[Bug 1971434] Re: Display powersave only blanks, but does not turn off

2024-10-15 Thread Philipp Wendler
Thanks for working on this!

The discussion about unplug events being the cause made me wonder
whether this is also the source of a similar problem I have as well: On
my ThinkPad T14 with Ubuntu 22.04 and Wayland, closing the lid wakes the
notebook up from sleep mode. I.e., if I enter standby and then close the
lid, the notebook wakes up. If I directly close the lid, the notebook
enters standby mode and stays there. Of course it could also be that
this is due to a different cause, but I wanted to mention it here in
case it helps. I let "udevadm monitor"  run through a "standby - close
lid - wake up" cycle but the only "bind|unbind|add|remove" messages that
it showed were for USB devices (plus some "change" messages for
drm/card1 and my NVME disk).

For the problem with the HDMI monitor on my other machine I could
produce an event log tomorrow if desired, or perform other debugging you
would like to see. For me the problem also happens reliably on my other
machine. (Though interestingly, on the monitor where my main machine
shows the problem, my ThinkPad does not show it. Both run Ubuntu 22.04
Wayland and have an AMD GPU.)

I can confirm #52: Works fine for me on DisplayPort, broken on HDMI.

My system is described in #21.

[Bug 1971093] Re: collectd missing in 22.04/jammy

2022-05-09 Thread Philipp Wendler
I have tried out the packages from Jammy proposed, and they work fine
here (Ubuntu 22.04, many collectd plugins active, forwarding to a
Graphite server). Debian sid also has collectd 5.12.0-9 with the exact
same changelog as the Ubuntu package (https://metadata.ftp-
master.debian.org/changelogs//main/c/collectd/collectd_5.12.0-9_changelog)
with no recent bugs in their tracker. So there does not seem to be a
reason why Ubuntu should not ship that package.

Anway, if a package is shipped and later removed from the package
repository for whatever reason, I would expect to be able to find the
reason for this somewhere, e.g., here in the bug tracker. But I could
not find any mention of this.

[Bug 1567565] Re: Permission error saving a file

2021-11-06 Thread Philipp Wendler
This problem persists with recent versions of Ubuntu and Evince when
editing files on CIFS/SMB shares, even after disabling AppArmor.

The reason for this is that Evince attempts to move the temporary file over the 
original PDF while it still has the latter file open, and overwriting open 
files is not supported by SMB:

** Tags added: apport-collected

** Description changed:

  Since kernel 5.4.0-89.100 on Focal and 4.15.0-159.167 on Bionic I can no
  longer mount an overlay filesystem over directories like / in a user
  namespace. With kernel versions 5.4.0-88.99 and 4.15.0-158.166,
  respectively, this still works.
  
  An easy way to test this is the following command:
  mkdir /tmp/test /tmp/test/upper /tmp/test/work
  unshare -m -U -r mount -t overlay none / -o 
lowerdir=/,upperdir=/tmp/test/upper,workdir=/tmp/test/work
  
  On an older kernel, this works and outputs nothing.
  On the affected kernels, it outputs
  
  mount: /: wrong fs type, bad option, bad superblock on none, missing
  codepage or helper program, or other error.
  
  I strongly suspect that this is due to commit "ovl: prevent private
  clone if bind mount is not allowed"
  
(https://github.com/torvalds/linux/commit/427215d85e8d1476da1a86b8d67aceb485eb3631),
  which is supposed to fix CVE-2021-3732 and was backported to the
  affected Ubuntu kernels. This would likely mean that also all other
  supported Ubuntu versions are affected and also upstream kernel (but I
  did not test this).
  
  My testing indicates that the mount problem exists whenever I want to
  use a directory as lowerdir that has some mountpoints below. For
  example, using / or /dev as lowerdir does not work, but
  lowerdir=/dev/shm works even on the affected kernels.
  
  Of course I can understand the problem of CVE-2021-3732, but the current
  fix is clearly a regression for legitimate behavior.
  
  My use case is that I want to create a container for sandboxing purposes
  where I want to mount overlays inside a user+mount namespace over the
  whole visible filesystem hierarchy. (Note that in this use case, I
  iterate over all mount points and create an overlay mount for each
  existing mount point, I do not expect a single overlay mount to have
  meaningful cross-mountpoint behavior. So my use case is not affected by
  the security problem. But for this I still need to be able to create
  overlay mounts for all mount points, including non-leave mountpoints.)

2021-04-13 Thread Philipp Wendler
We also experience this bug on Focal. It is a real issue for us because
unattended-upgrades relies on the `users` command to determine logged-in
users. This means that on Focal, unattended-upgrades reboots forcefully
and kills running tmux sessions even if instructed not to with
`Unattended-Upgrade::Automatic-Reboot-WithUsers "false";` in the apt
config.

Ok, just wanted to make sure this is the case.

Thanks!

I tested it on a Focal machine and the -proposed kernel works. However,
I don't have a Groovy machine here, is it necessary for me to test this?

I noticed that in the list of affected packages in the bug metadata
Bionic is not mentioned. Will the fix also be backported there?

2020-11-23 Thread Philipp Wendler
I noticed that the changelog of the kernel package 5.4.0-50.55~18.04.1
for Bionic now also includes the two additional patches, and indeed I
can confirm that on Bionic with kernel 5.4.0-54-generic the regression
was now also introduced.

Is there an update whether it will be possible to solve this regression?
It breaks our container runtime unfortunately.

[Bug 1900141] [NEW] overlay: permission regression in 5.4.0-51.56 due to patches related to CVE-2020-16120

2020-10-16 Thread Philipp Wendler
Public bug reported:

We use unprivileged user namespaces with overlay mounts for containers.
After recently upgrading our Focal kernels to 5.4.0-51.56 this breaks,
one cannot access files through the overlay mount in the container
anymore. This is very likely caused by some of the patches that were
added in relation to CVE-2020-16120.

The following commands allow to reproduce the problem when executed as
an arbitrary non-root user:

mkdir /tmp/test /tmp/test/upper /tmp/test/work /tmp/test/usr
unshare -m -U -r /bin/sh -c "mount -t overlay none /tmp/test/usr -o 
lowerdir=/usr,upperdir=/tmp/test/upper,workdir=/tmp/test/work; ls -l 
/tmp/test/usr/bin/id; file /tmp/test/usr/bin/id; /tmp/test/usr/bin/id"

The output when broken is this:

-rwxr-xr-x 1 nobody nogroup 47480 Sep  5  2019 /tmp/test/usr/bin/id
/tmp/test/usr/bin/id: executable, regular file, no read permission
/bin/sh: 1: /tmp/test/usr/bin/id: Operation not permitted

The expected output is this:

-rwxr-xr-x 1 nobody nogroup 43224 Jan 18  2018 /tmp/test/usr/bin/id
/tmp/test/usr/bin/id: ELF 64-bit LSB shared object, ...
uid=0(root) gid=0(root) groups=0(root),65534(nogroup)

These commands create a user namespace and within it mount an overlay of
/usr to /tmp/test/usr and then try to access something in it.

This works on Ubuntu Bionic with kernel 4.15.0-121.123 (note that this
already includes a fix for CVE-2020-16120) and on kernel 5.4.0-48.52 but
is broken on kernel 5.4.0-51.56, no matter whether on Bionic or Focal.

So I strongly suspect that not the actual security fixes for
CVE-2020-16120 are the cause, but one of the following two patches that
according to the changelogs were applied in the same revision but only
to 5.4, not to 4.15:

ovl: call secutiry hook in ovl_real_ioctl()
ovl: check permission to open real file

The mail with the announcement (https://www.openwall.com/lists/oss-
security/2020/10/13/6) lists these two commits as separate from the
actual security fixes ("may be desired or necessary").

Is it possible to revert these two changes or fix them such that our
unprivileged containers work again on Ubuntu kernel 5.4? Or is there a
workaround that I can add to my container solution such that this use
case works again?

[Bug 1793458] Re: Overlayfs in user namespace leaks directory content of inaccessible directories

2018-11-19 Thread Philipp Wendler
I find the demand to test the fix within 5 days, combined with the
threat of dropping the patch otherwise, unreasonable.

In my original report of this security problem I have already provided a
script that allows to reproduce the problem and check if it still
exists.

Requiring an answer within 5 days is too short, after all people can be
on holiday or just busy for other reasons.

And even if I as the original submitter wouldn't respond at all, this is
a real security problem in Ubuntu that was already confirmed. Are you
really going to drop the patch and let CVE-2018-6559 stay unfixed
forever?

Maybe I will find the time to test it on Bionic, but I will certainly
not install a different version of Ubuntu than the one I am currently
running.

I hope that this is all just a misunderstanding and the message does not
apply to security problems. In this case please consider changing the
message or improving the process such that this confusion will be
avoided for future reports.

[Bug 1633413] Re: Obsolete authenthication requests for WiFi

2017-01-25 Thread Philipp Wendler
I agree that this is very inconvenient. For example, I have a system at
home that I leave unattended but I need it to reconnect automatically to
my wifi, because I need to access it from abroad. If there is a
disconnect and it can't reconnect immediately (e.g., because of a router
reboot), the password dialog will prevent network manager from
connecting to my wifi again, effectively killing my access to this
machine.

So I would say that even if network manager needs to ask for the
password because it can't know whether the password is correct, this
should not block all other operations: network manager should try
connecting to the wifi in the background (and if it succeeds, hide the
dialog).

This is also asked here: https://bugzilla.gnome.org/show_bug.cgi?id=680625

[Bug 1619677] Re: Intel Skylake video: no output on VGA port

2016-10-20 Thread Philipp Wendler
We are also experiencing such problems on a range of different notebooks
with an Intel HD Graphics 520 (Skylake generation). We tested multiple
Fujitsu Lifebook E746 with their onboard VGA connector and a ThinkPad
T460s with different adapters from DisplayPort, under both Ubuntu 16.04
with kernel 4.4 and Ubuntu 16.10 with kernel 4.8.

In a few cases (certain combinations of notebooks and projectors) we got
a working VGA connection, bust mostly not. If a connection could be
established, it was stable.

It seems that VGA ports on Linux with Skylake GPUs are completely
unreliable.

According to http://www.anandtech.com/show/9483/intel-skylake-review-
6700k-6600k-ddr4-ddr3-ipc-6th-generation/4, Skylake has no internal VGA
port anymore and all VGA connectors are build using adapters, which
could explain this (worse timings and signal quality for example).

However, Windows 10 on the same notebooks never had a problem with VGA
output in our tests, so it seems that there is still some influence of
the OS.

This is a major problem for our users because they absolutely rely on a
working VGA connector, because when giving talks (for example on
academic conferences) it is still the norm that only a VGA connection to
the projector is available.

2016-04-26 Thread Philipp Wendler
I tested 4.4.0-22.38_amd64 on Ubuntu 14.04 with an overlay over an NFS4
mount (same situation as in comment #7) and the crash when reading
existing files from the lower layer is gone.

I did not test overlay over NFS3.

I still cannot successfully write to files that exist in the lower layer
("Operation not supported"), only to new files, but I guess this is not
in the scope of this bug report.

2016-04-13 Thread Philipp Wendler
I also experience this problem using the Xenial kernel 4.4.0-18.34~14.04.1 on 
Ubuntu 14.04.
I can even reproduce it as a non-root user by creating an overlay mount inside 
a user namespace.

After mounting an overlay over an NFS mount, I can successfully traverse
existing directories and create, write, read, and remove new files. As
soon as I try to read an existing file (from the lower layer NFS mount),
the application that attempts the read dies and the syslog shows the
kernel bug. The system continues running afterwards.

Furthermore, a similar crash occurs for NFS 4 mounts:

2014-12-08 Thread Philipp Wendler
For auditing my PAM config, could you please tell me which PAM config the lock 
screen uses
(i.e., which file in /etc/pam.d is used)?
So far I could not find any differences between them.
The LDAP config is in common-{auth,account}, which are included in most files 
in this directory.
All these services (login, lightdm, polkit-1, sudo, sshd) are working fine.

[Bug 1311316] Re: After locking screen there is no input field to type password for unlock

2014-12-08 Thread Philipp Wendler
I cannot imagine how a missing password input field in the lock screen could be 
related to an LDAP configuration issue on our side.
If the authentication would fail after entering the password, then yes, of 
course this could be such a problem.
But a password field should always be shown by the unlock screen, regardless of 
the authentication backend.

Also our LDAP configuration is working for several years now without problems.
Only since the upgrade to Ubuntu 14.04 this problem with the lock screen has 
started appearing.
All other applications, including the login screen (lightdm) are working fine.

By the way, we have a dual monitor setup, too.
Our home file systems are on an NFS fileserver, mounted using automount and 
with root_squash enabled (this means that root does not have full access to my 
home directory, but only the same rights as all other accounts). If there is a 
root process trying to access files in my home this would fail.

[Bug 1311316] Re: After locking screen there is no input field to type password for unlock

2014-12-05 Thread Philipp Wendler
We also have this problem on several machines, and I hope I can contribute to 
getting it fixed.
Removing light-locker fixed the "double unlock" problem, but not this problem. 
The machine is a fully up-to-date Ubuntu 14.04 with LDAP authentication.

The output of ls -l /sbin/unix_chkpwd is
-rwxr-sr-x 1 root shadow 35536 Jan 31  2014 /sbin/unix_chkpwd
I cannot post full auth.log because of personal data,
but I will try to remember to grap the last lines of the log the next time the 
problem appears.

The problem occurs only randomly and not very often (maybe once per
week). It happens less often now that the "double unlock" problem is
fixed, I guess simply because I have to enter my password less often
now.

A reliable work around is to switch to a text console, login as the same user, 
and run "unity --replace".
This restores the password input field. After unlocking, the panels are missing 
but I can fix this by opening a terminal window and running "unity --replace" 
there.

[Bug 1341628] Re: [needs-packaging]openjdk-8 in 14.04

2014-07-14 Thread Philipp Wendler
During the life time of 14.04, we expect many Java applications to switch to 
and rely on Java 8
(given the nice programming benefits this offers, the switch probably happens 
faster than for e.g. Java 7).
We are considering making this change for our own open-source Java application, 
too.

Thus 14.04 should offer a convenient way to install openjdk-8.

[Bug 1315464] [NEW] Cannot login if ~/.cache is dead symlink

2014-05-02 Thread Philipp Wendler
Public bug reported:

On Ubuntu 14.04, graphical logins fail if ~/.cache is a dead symlink.
Only the background picture and the mouse cursor is shown during login,
and nothing else is started. Console logins still work.

This happens independently of the login manager (tested lightdm, gdm,
and kdm) and the session (tested unity, gnome-shell, kde, and xfce).
Therefore I guess upstart (the "init --user" process) is the problem, as
it tries to log in to ~/.cache/upstart/.

My version of upstart is 1.12.1-0ubuntu4.

Steps to reproduce:

mv .cache cache.bak
ln -s /non-existent .cache
Try logging in.

I would expect that logging in just works without using the .cache
directory in this case (e.g., not logging to .cache/upstart), or that
the dead symlink would be silently removed and the directory created, or
that an error message would appear and login would be aborted. The
current situation is bad because it is very hard to find the cause of
the login problem (I just stumbled upon it by accident).

[Bug 1297065] Re: [needs-packaging]openjdk-8 in ubuntu

2014-03-28 Thread Philipp Wendler
It would be great if it could land at least in Trusty, so that we don't
have a LTS version where the only available Java version is quite
outdated. I expect many Java programs to require Java 8 some time while
Trusty is still supported.

In fact, I am also a Java developer, and we will surely switch to Java 8
somewhere in the next 2 years. As most of our users are based on LTS
versions of Ubuntu, having Java 8 in Trusty would be a major improvement
for us.

[Bug 1008344] Re: checks "admin" group membership instead of querying polkit

2013-01-31 Thread Philipp Wendler
Please, drop the is_admin check completely.

I said it already: "you cannot know whether the user knows the password
of an admin account if you do not ask for it". If you try guessing, you
will inevitable guess wrong sometimes and frustrate the user. This is
also true if polkit does the guessing.

If you do not want to confuse user with admin buttons, then, either put
a lock symbol on all of them, of grey them out and add a single unlock
button just like the time settings dialog.

For the check for missing packages, you can just add a button "check for
missing packages", or run the check when the user clicks the unlock
button. Or you convert the popup that asks the user into a text and
button in the language dialog, something along "Missing packages detect.
[ Install them]".

This solution is easy to implement, does not require new polkit
features, has a clear, obvious, ui, and does not get in the way of users
by hiding things from them they would like to see.

[Bug 1008344] Re: checks "admin" group membership instead of querying polkit

2013-01-02 Thread Philipp Wendler
I would get rid of greying out these buttons completely.

You will never know whether the user is able to authenticate as admin,
because you cannot know whether the user knows the password of an admin
account if you do not ask for it. In all cases where the buttons are
greyed out, but the user would know how to authenticate, this will
create frustration.

Furthermore, there is no advantage of having the buttons greyed out. If
you want to signal to the user that they require more rights, you can
put a lock symbol on them (isn't there an example in the time settings
dialogue for this?).

This solution would be the easiest to implement and to use.

[Bug 1008344] Re: [Precise] Language selector won't allow me to install languages

2012-12-12 Thread Philipp Wendler
@Gunnar: As I said in the bug report, this is an installation which uses
user accounts and groups from an LDAP directory. There is an LDAP group
for all network-wide admins, and I am in this group. This group is
enabled for sudo and policykit admin rights in the appropriate config
files, and I expect all users within this group to have all available
permissions. I certainly don't want to edit code files in /usr/lib to
give myself additional rights.

I also don't want do put all admin users into the local groups "sudo" or
"admin", because this defeats the whole purpose of an LDAP directory
(i.e., I would have to change files on all machines in the network
whenever there is a new admin or one leaves). It is also not an option
to distribute the groups "sudo" and "admin" via LDAP, because then
nothing works on the machine in an emergency when the LDAP server is
down (it is generally not recommended to distribute any uids and gids <
1000 via LDAP for this reason).

You are also wrong about the "way that is compatible with how Ubuntu
handles these things". Ubuntu uses sudo and policykit, and I am using
these ways.

Note that language-selector does not need to know about the existence of
any files (and should not), it should just ask policykit whether the
user has admin rights. That's the way all other applications work (if
they don't use sudo).

Ok, so I added the group I am in as an AdminIdentity in this file.
However, in the language selector, the relevant buttons are still grayed

I am very confident that my change to

changed something for the user account administration that is also part
of gnome-control-center. Previously this would ask me for the root
password, now I am able to unlock the settings there with my own
password (or one of the other accounts in the new admin group). So this
should work for the language selector, too.

[Bug 1012016] [NEW] Dash is not usable with resolution of 768x1366 (tablet)

2012-06-12 Thread Philipp Wendler
Public bug reported:

When the horizontal resolution is very small (e.g., 768px on my
convertible in tablet mode), the dash runs off to the screen to the
right (cf. screenshot). There is bug #837922 from 2011 which is marked
as fixed, but the problem exists on a fresh install of Precise (using
unity-3d).

[Bug 197957] Re: Include a libasound2-plugins-extra package for a52, maemo

2012-06-06 Thread Philipp Wendler
Mike,
HDMI really supports multi-channel PCM. I am not sure, though, if all receivers 
support it, and if the Linux drivers of all video card brands support it. I 
have a Denon receiver and an Intel IGP, and it works nicely out-of-the-box 
under Ubuntu since 11.10. I just need to select the appropriate output in the 
sound control applet.

Of course having a52 would still be nice for people without such
hardware.

2012-06-06 Thread Philipp Wendler
If you have hardware that supports HDMI (both your computer and your
receiver), you can use HDMI to transport uncompressed multi-channel
audio (up to 6-8 channels) and don't need the a52 plugin. Of course, if
you are stuck to older hardware without HDMI, that's no solution, but I
guess a lot of people will be able to use HDMI nowadays.

[Bug 1008344] [NEW] [Precise] Language selector won't allow me to install languages

2012-06-03 Thread Philipp Wendler
Public bug reported:

In a new install of Ubuntu Precise, I cannot make any system-wide
changes in the language selector (such as installing languages or
clicking "Apply System-Wide"), only user-specific changes. All those
controls for system-wide changes are greyed out, although my user does
have sudo abilities and I would be able to enter the root password of
the machine.

The machine is freshly installed, but with customizations specific to
our site, e.g. ldap authentication for users. Specifically, my user is
an ldap user, not a local one, and there is a group in the ldap
directory which was granted sudo capability by adding it to
/etc/sudoers. My user is part of that group. sudo on the command line
and gksudo work fine.

[Bug 997740] Re: cant send bug reports - apport crashes without message

2012-05-12 Thread Philipp Wendler
This happens for me everytime apport comes up and asks to send a bug report, 
too.
Both for crashes of system applications (where I need to enter my password) as 
well as for crashes of user applications.
I can see the window where the crash details are listed, but nothing happens 
when clicking "Continue" (except that the window closes).

I found a discussion from 2008 on the net which seems to indicate that
this is by design and won't get changed:

Sad, but probably there is nothing that can be done about this (aside
from using Kerberos, syncing IDs, or switching to Samba).

[Bug 887904] Re: [Oneiric] Ecryptfs kills 3D support of my video driver

2012-01-02 Thread Philipp Wendler
@Dustin
The pause on login is much much longer than manually doing a 
ecryptfs-mount-private. The latter takes about half a second of CPU time, 
whereas the pause on login is much longer (I guess around 10s, although I 
didn't measure it). So I think its not only the key strengthening.

[Bug 887904] Re: [Oneiric] Ecryptfs kills 3D support of my video driver

2012-01-02 Thread Philipp Wendler

** Tags added: apport-collected staging

** Description changed:

  I have a machine which I upgraded from Natty to Oneiric a week ago. It
  uses the onboard graphics card of Intel SandyBridge CPUs, and Unity as
  well as HDMI audio output worked fine.
  
  A few days ago I installed ecryptfs-utils and set up a encrypted
  directory. I did not use the login password, but a separate password,
  and I move the .Private directory to another partition (creating a
  symlink in my home directory). I did no login or logout since that.
  
  Yesterday I was fiddling with my screen resolutions and had some
  problems, so I tried to login/logout and reboot. Now a lot of weird
  things happen:
  
  First, when I login, after entering my password  and hitting enter, there is 
a pause of several seconds, during which nothing seems to happen, but the 
lightdm process takes 100% CPU.
  Second, 3D support of my video driver is suddenly gone. The 
/usr/lib/nux/unity_support_test says that software rendering is used. In dmesg, 
there are messages about "invalid framebuffer ids" and "composite sync not 
supported". Of couse unity is not working (only unity-2d).
  Third, all my audio devices are gone in the output of aplay -L (only the alsa 
default device that points to PulseAudio is there). If I run aplay -L on a 
terminal (not within X), all devices are there! Of course sound is also not 
working.
  
  I verified that ecryptfs is the problem. If I remove/rename the
  .ecryptfs folder in my home directory, i can log in fine (without
  pause), and 3D and audio are working. If I move the folder back, and try
  to login again, the problems are there. I do not even need to reboot
  between the logins. In one login my graphics card seems to be completely
  unsupported, and in the next login it is the usually well supported
  Intel graphics card again.

I have heard of gnome-tweak-tool, but I have also heard a lot of
warnings about it, which say that it shouldn't be used for Ubuntu. So
this is not a recommendation we could give to users.

I just verified that the problem exists regardless of whether the target
directory of my ~/.Private symlink exists. It only depends on the
existence of the .ecryptfs directory.

between the logins. In one login my graphics card seems to be completely
unsupported, and in the next login it is the usually well supported
Intel graphics card again.

I talked to the Pulseaudio developers on IRC. Disabling the module
"module-suspend-on-idle" solves this problem.

2011-11-01 Thread Philipp Wendler
It also works if I switch the Pulseaudio output configuration to
"Digital Stereo (HDMI) output" and back while the sound is playing. As
soon as the first change is done, I hear sound (in stereo, of course)
and after the second change I have nice 5.1 sound.

So Pulseaudio is clearly able to do everything necessary to have sound,
it just needs to do it automatically when starting playback.

[Bug 884336] [NEW] [Oneiric] HDMI output does not work immediately

2011-10-31 Thread Philipp Wendler
Public bug reported:

In Oneiric, the output of 5.1 sound (not AC3 passthrough, but multi-
channel PCM) via the HDMI connector of my onboard Intel graphics card is
finally working. This is really great!

For this to work, I have configured Pulseaudio to use the "Digital
Surround 5.1 (HDMI) Output". The HDMI output of my computer is connected
to a 5.1 receiver.

However, there is one nuisance: Whenever I start playing sound on the
computer (e.g., rhythmbox or VLC, both playing via PulseAudio), I hear
no sound. On my receiver I have to re-select the input source for the
computer, which seems to initiate a HDMI handshake (it lasts 3 seconds).
Only after this I am able to hear sound.

If I press pause and continue in Rhythmbox, the sound continues fine. If
I stop and restart Rhythmbox, I have to do the above procedure again.
The same is true for VLC and probably for all other players.

While playing around, I have noticed that sound is also working after
killing pulseaudio while playing something in Rhythmbox. When the
connection to Pulseaudio is killed, Rhythmbox tries a fallback to ALSA.
As the Pulseaudio daemon was immediately restarted, this will result in
Rhythmbox being connected via the ALSA plugin (before the connection was
direct). It seems that Pulseaudio is doing the necessary things here,
because after this I do hear sound (as long as Rhythmbox runs). However,
this trick does not work for other players like VLC which don't fall
back to ALSA.

Note that while for me this is just a nuisance, it may be a real blocker
for other users. As long as you don't try to fiddle with the receiver
inputs while playing sound on the computer, you hear absolutely nothing
via HDMI. This includes the sounds from the speaker test dialog of
Pulseaudio. I guess a lot of users would give up and think that HDMI
output is broken in Ubuntu.

[Bug 884251] [NEW] [Oneiric] Now way to configure font hinting and subpixel order

2011-10-31 Thread Philipp Wendler
Public bug reported:

On my old Ubuntu installation, I had enabled font hinting and configured
the subpixel order so that the fonts look well on my LCD.

On my fresh Oneiric installation, there is no way to do so, and the
fonts look really ugly in some places (e.g., in the panel). They appear
to be blurry, which disturbs me very much. My eyes even keep moving up
the place where the indicators sit just because there is something there
that doesn't look right. Ubuntu really needs a way to configure these
things if they can't be detected automatically.

[Bug 863547] Re: Setting screen resolution fails with error message "null"

2011-10-22 Thread Philipp Wendler
Hi,

currently only a part of this bug is reproducible. The error message
does not appear anymore, but changing resolutions, enabling/disabling
monitors etc. does not work. Whatever I do in this dialogue, absolutely
nothing happens when I click "apply".

Changing resolutions etc. on the command line works well.

My monitor setup is as follows:

2011-10-04 Thread Philipp Wendler
Hi Sebastien,

indeed, it seems to be working now with version 3.2.0-0ubuntu4
 of gnome-settings-daemon (even after setting sleep-inactive-battery to true).
So I close this bug. Thanks for fixing it.

[Bug 865720] Re: [Oneiric] Can't disable automatic standby (suspend-to-ram) on inactivity

2011-10-03 Thread Philipp Wendler
Alex: A much better temporary fix is this:

gsettings set org.gnome.settings-daemon.plugins.power sleep-inactive-battery 
false
gsettings set org.gnome.settings-daemon.plugins.power 
sleep-inactive-battery-timeout 0

Then you can revert the changes from the comment you mentioned.
The advantage here is that it will not prevent you from manually going to 
standby.
