[Bug 1896498] [NEW] Ubuntu installer failed while trying "fresh" install over existing instalation on btrfs

2020-09-21 Thread João Manuel Rodrigues
Public bug reported:

I have a previous installation of Ubuntu 16.04.
My disk has 2 GPT partitions:
/dev/sda1   for /boot/efi
/dev/sda2  btrfs  with 2 subvolumes: @ mounted as /, @home mounted as /home.

I tried a fresh install of Ubuntu 20.04.1.  I selected manual
partitioning and /dev/sda1 was recognized as Boot/efi.  I had to select
/dev/sda2 and specify "mount as" / (there is no better alternative).  I
proceeded and verified on a terminal that the installer detected the
subvolumes just fine:

ubuntu@ubuntu:~$ mount | grep sda
/dev/sda2 on /target type btrfs 
(rw,relatime,ssd,space_cache,subvolid=257,subvol=/@)
/dev/sda1 on /target/boot/efi type vfat 
(rw,relatime,fmask=0077,dmask=0077,codepage=437,iocharset=iso8859-1,shortname=mixed,errors=remount-ro)
/dev/sda2 on /target/home type btrfs 
(rw,relatime,ssd,space_cache,subvolid=258,subvol=/@home)

The instalation went on to copy files, all seemed fine.  When the step
"Creating a user" was reached, the installer crashed with an unspecified
error.

I'm on Ubuntu 16.04 (Xenial). I just did a `apt update; apt upgrade`.

~$ apt show openjdk-9-jdk

If I install this package I still get the error, so it seems the fixed
version is not in the Xenial repos, yet.

[Bug 1393469] Re: indicator-printers does not show up when printing

2016-01-28 Thread João Manuel Rodrigues
I'm using Ubuntu 14.04, installed from scratch, not upgrade.
The only unusual setup I can think of is that my root partition is btrfs.

In my case, the problem is intermittent. Some days everything seems to
work as expected.

When it happens, I launch the system-config-printer tool and open the
printer's queue dialog.  This sends the jobs to the printer.

[Bug 1333773] Re: scanning for btrfs file systems on system startup

2014-12-22 Thread João Manuel Rodrigues
I have a fresh 14.04 installation.  I did set up a single partition as
btrfs, with 2 subvolumes for / and /home, so removing brtfs-tools is out
of question.

The Scanning for btrfs file systems appears early on, but stays there for 
some 25 seconds until  the boot resumes again.
The system finally boots and works fine afterwards, but the boot is definitely 
slow.  There must be a bug causing this delay.

[Bug 1341562] Re: indicator-printers not working on Ubuntu 14.04

2014-09-03 Thread João Manuel Rodrigues
I installed 14.04.1 (fresh, not an update) a week ago, and have kept it
up-to-date. I have only installed a couple of packages from the standard
repositories: vim, java, no fancy stuff.

I configured a couple of network printers (via SMB print server), and
noticed that when I print, no indicator appears. Also, the jobs won't
start printing until I open the corresponding print queue in the
Printers configuration application.  This may be related to the fact
that these printers require user authentication. Anyway, this is an
inconvenience that would probably be solved if the indicator-printers
applet were running properly.

I've installed mainline kernel
  linux-image-2.6.32-02063211-generic_2.6.32-02063211_i386.deb
and rebooted.
Tried a suspend and resume shows same symptoms as originally reported: no 
screen, no reaction.

I've also tried kernel
  linux-image-2.6.34-999-generic_2.6.34-999.201005181210_i386.deb
and had symptoms similar to what adline reported above:
system seems to resume, but the screen shows alternating patterns of horizontal 
lines or random dots.  Tried to switch to other consoles (Alt-F1) but the 
screen remained unintelligible. There is reaction to CapsLock, and I was able 
to use Alt-SysRq key combinations to terminate/sync/reboot.

Public bug reported:

After a suspend, touching a key will restart the fans and there's disk
activity, but the screen remains blank and there's no reaction to key
presses (CapsLock won't toggle the led).

This is a fresh install of Lucid Lynx 10.04, not an upgrade.
Suspend/resume has worked on this machine with several previous versions

[Bug 538697] [NEW] Usplash turns off screen and locks the system while checking filesytem

2010-03-14 Thread João Manuel Rodrigues
Public bug reported:

Binary package hint: usplash

On a specific type of computer, while booting, a routine check of the
root filesystem started and almost immediately the screen turned black
and entered a power-saving mode.  If left alone for some more time (1
minute or so), the computer stops responding: pressing NumLk or CapsLk
won't toggle the LEDs, Alt-SysRq comands do nothing, and even pressing
the soft-off button does nothing.  This is critical because the next
boot (after switching off then on) will force a fsck again with the same
result.

While the screen is blank, if I switch to text console (e.g. with
Alt-F8) soon enough, I can see the fsck and the boot process completing
normally.

Removing the splash boot option also allows a clean boot.  This is a
valid workaround.

On a normal boot, whithout filesystem checks, usplash runs normally.

The problem is repeatable: just 'touch /forcefsck' and reboot.  I tested
in 2 or 3 identical computers with the same results.

This seems to be hardware related since the exact same instalation in
different computers never showed this behavior.

Hardware summary:
ASUS P4R8L motherboard
Intel(R) Pentium(R) 4 CPU 3.00GHz

[Bug 538697] Re: Usplash turns off screen and locks the system while checking filesytem

2010-03-14 Thread João Manuel Rodrigues
** Description changed:

  Binary package hint: usplash
  
  On a specific type of computer, while booting, a routine check of the
  root filesystem started and almost immediately the screen turned black
  and entered a power-saving mode.  If left alone for some more time (1
  minute or so), the computer stops responding: pressing NumLk or CapsLk
  won't toggle the LEDs, Alt-SysRq comands do nothing, and even pressing
  the soft-off button does nothing.  This is critical because the next
  boot (after switching off then on) will force a fsck again with the same
  result.
  
  While the screen is blank, if I switch to text console (e.g. with
  Alt-F8) soon enough, I can see the fsck and the boot process completing
  normally.
  
  Removing the splash boot option also allows a clean boot.  This is a
  valid workaround.
  
  On a normal boot, whithout filesystem checks, usplash runs normally.
  
  The problem is repeatable: just 'touch /forcefsck' and reboot.  I tested
  in 2 or 3 identical computers with the same results.
  
  This seems to be hardware related since the exact same instalation in
  different computers never showed this behavior.
  
  Hardware summary:
  ASUS P4R8L motherboard
  Intel(R) Pentium(R) 4 CPU 3.00GHz
  Radeon 9100 IGP

[Bug 120015] useradd too slow with LDAP nsswitch

2007-06-12 Thread João Manuel Rodrigues
Public bug reported:

Binary package hint: passwd

In a machine with nsswitch configured to used a LDAP server with around
5 users, trying to add a new local user (with useradd) takes a
really long time.

My /etc/nsswitch.conf contains this:
passwd: files ldap
group:  files
shadow: files
hosts:  files dns mdns
#hosts:  dns [!UNAVAIL=return] files mdns  #UA2006 ?
networks:   files
protocols:  db files
services:   db files
ethers: db files
rpc:db files
netgroup:   nis

An strace shows that useradd is fetching a full list of users from the
server: on my system his takes a long time.  Commenting out the ldap
in nsswitch immediately solves the problem.

Maybe this is a feature but I can't see why adding a new user should
need to verifiy every existing user.

Using the command  newusers, there is no problem even with LDAP
activated.

[Bug 120015] Re: useradd too slow with LDAP nsswitch

2007-06-12 Thread João Manuel Rodrigues
Forgot to say:
I'm using Ubuntu 6.06 but I recall similar behavior with a Mandrake 10.1 distro 
a few years ago.  This is probably a upstream problem.

Some more info:
In my current setup, ldap is only used for the passwd DB --- Kerberos is used 
for authentication, so there is no need for shadow DB from nsswitch.  I've 
installed libnss-ldap, but not libpam-ldap.

I tried creating users both with and without options specifying UID and GID:
   useradd johndoe
   useradd -u 1234 johndoe
   useradd -u 1234 -g 100 johndoe
All had the same problem.  (I hoped that by specifying a UID only a single 
lookup would be made, but strace reveals the same behavior: fetching the full 
DB.)

Sorry for the typos in the previous comment.

[Bug 67487] Re: Install 6:10 Failure: Black screen at Live Desktop Stage

2006-11-02 Thread João Manuel Rodrigues

I agree with Slogger that this might be related with bug #22985. At least some 
of the problems mentioned here look similar, but there are some new issues, too.

Bug #22985 comes from Dapper (6.06), still exists in Edgy (6.10).  In
Dapper, switching to a console worked fine and a fix was easy to apply.
In Edgy there seem to be problems with the console, too, which should be
a different problem but very much worsens the situation.

I have an Acer Aspire 1692WLMi laptop (Pentium M, ATI X700 PCI-E,
1280x800 LCD) and had bug #22985 with Dapper: when X ran, LCD turned
black, it seemed like the backlight was turned off.  Possibly there was
signal on the CRT output, but I can't recall that now.

I have only tried Edgy-live once and this is what I recall:
LCD turned black on X startup, just like on Dapper.  Tried switching to console 
but it looked all garbled up... very unpleasant, but it looked like the system 
was running.

I was eventually able to boot and switch to a sane console by specifying
vga=771 boot parameter.

I'll try and repeat this later.  I'll confirm it here.

[Bug 30557] Re: cpu idle time in /proc/stat wrong

2006-09-14 Thread João Manuel Rodrigues
This probably does not belong here, but just to let you know:

With latest update of the 686 kernel (2.6.15-26.47), restricted modules 
(2.6.15.11-4) and proprietary ATI fglrx driver (7.0.0-8.25.18+2.6.15.11-4),
I now have hardware 3D with the 686 kernel.  Problem seems to be gone.

2006-08-14 Thread João Manuel Rodrigues
I confirm anonym's problems.

I have an Acer aspire 1692WLmi, Pentium M740 with ATI X700 graphics.
With the proprietary fglrx driver (version 8.25.18), hardware 3D is
unavailable with -686 kernel (version 2.6.15-26.46) but works with -386
kernel.  This can be verified by running glxinfo and checking the
direct rendering: line.

However, I suspect this may be a different bug, and possibly not with
the kernel but with the fglrx driver or the restricted kernel module it
needs.

[Bug 30557] Re: cpu idle time in /proc/stat wrong

2006-08-04 Thread João Manuel Rodrigues
I'm now running linux-image-2.6.15-26-686, version 2.6.15-26.46 on a
Pentium M 740 1.73MHz (Acer Aspire 1692WLMi).

So far, it seems fine: Without changing max_cstate, CPU rapidly throtles
down to 800MHz and, when idle, CPU usage settles around 5--6%.  Starting
new apps, such as opening a firefox window, does not feel sluggish like
it used to.

Here is a sample of data taken some 19 minutes after booting, laptop
connected to AC power, with Wi-Fi on and a USB mouse plugged in:

$ cat /sys/module/processor/parameters/max_cstate
8

$ top

top - 18:56:55 up 14 min,  3 users,  load average: 0.08, 0.33, 0.27

Cpu(s):  5.3% us,  0.0% sy,  0.0% ni, 94.7% id,  0.0% wa,  0.0% hi,  0.0% si

$ cat /proc/acpi/processor/CPU*/power

Looks like this one is fixed.  Thanks.
