Bug#622894: xserver-xorg: VT switching does not work.

2011-04-15 Thread John D. Hendrickson and Sara Darnell

rununtil you get it sorted out why...

there are program(s) to refresh vga text mode / save restore vesa.  run 
it and you'll have your text terminal.


note because VT depends on kernel etc you problem might depend on how 
you start x, not just X drivers or a flaky video card

VT switching (via Ctrl-Alt-F[1-6]) does not work.   When trying to switch, X 
seems to freeze: no response to kbd, mouse pointer disappears, xclock stops 
dead.

But, in fact the VT has switched, it is just not reflected on video:  Can type commands, 
restart xdm and suchlike, when typing blind.  And, when switching "back" to VT7 
(via Alt+F7) everything pops back into life.

This is the very behaviour I reported before for xserver-xorg 7.3+20 (i386).

On some occasions though I couldn't get back to VT7, only solution left was 
magic sysrq -- or power button.

Just add '*** xmodmap is obsolete, try setxkbmap instead ***'
somewhere on the xmodmap manpage. That would help #584502 sufferers too.

Bug#619033: xserver-xorg-video-intel: External screen shakes

2011-03-20 Thread John D. Hendrickson and Sara Darnell
but you can set the sync modes before X startup or after - so saying it 
is UBUNTU's error is wrong.  it is Ubuntu's correctness to use the 
better frequencies maybe


VERY NORMAL.

I have used vga extended cables or switchbox, but not with that exact 
card - and using them reduces quality


video stability IS very picky / requires a ton of fidelity and 
bandwidth.  thus network cables can't carry video.  stability also 
depends on the monitor's electronics / abilities.  (btw I know nothing 
of LED monitor pinouts / signals)

Bug#618622: crash when resizing screen while running a fullscreen application

Why blame X ?

many desktops / window managers will send X a HUP signal on exit.  a bad 
application might even do it.


First show was closed by UNIX or X itself decided to exit.

Bug#617969: xserver-xorg-core: Weird behavior/crash with specific usage

2011-03-15 Thread John D. Hendrickson and Sara Darnell

You said radeon right?  I don't have that but here's some tips.

/usr/X11R7/bin/Xorg (that's the name of your "real X server") 
automatically makes a config (example /etc/X11/Xorg-config-4).


What you want is to run Xorg with option to save the config.  Editing 
that config you'll see mouse, keyboard, video card, fonts, etc that X 
will try to use upon startup.  You have to tell Xorg to use the config 
on startup (because it will try to do it automatic as usual).


You'd like to look at someone else's config.  You might see  1) your 
loading modules you might not need  2) your loading modules you don't 
have  3) how to run in a more basic / stable mode until you get things 
figured out.


You'll have to ask someone else how exactly not to load 3D because I 
don't use Xorg and I don't have a radeon chipset video card.


You might also try: xserver-xorg-video-radeon.  And there's also the 
Debian Alioth website if you haven't found it yet.

Judging by the direction of Gnome for the past few years, this

I had tried keyboard-configuration.  Again, it doesn't get close to the
level of flexibility I want.  How do I set the Pause key as Compose?
I keep doing that with an Xmodmap file, and praying that my way will
continue to work.


I'm sorry I didn't study that much about keyboard yet, I think setxkbmap
is the preferred tool now, but I don't know much about it. At least not
more than Xmodmap that I don't use ;)

Julien> Doesn't your-favorite-editor and /etc/X11/xorg.conf.d/ fill that

First, there is no such directory on my system.  I see that it is
mentioned in the manpage, but without it being created by the package
(even if empty) I simply didn't know a split configuration was possible
for the X server.  It certainly wasn't so in XFree86.


I think that's a point, this directory should probably be created.


Second, yes, in general and for a random package, I am quite capable of
writing a configuration file by hand.  The X server is different.  Why?
Because the hierarchical, bottom-up format of the file forces me to
write the entire configuration, reproducing all the defaults even in the
parts totally unrelated to what I'm trying to customize.  For instance,
to modify the synaptics behavior, I cannot simply write a Pointer
section and be done.  To get it used, I have to have a ServerLayout
section, therefore I also need a Screen section, and once I have one I
better get all the most obscure settings there right.


Well basically this is not true anymore, you can write 'just' the
synaptics configuration, as explained in the doc I pointed to you earlier.
And even without /etc/X11/xorg.conf.d/ you can write partial xorg.conf
now, with just your synaptics configuration in it for instance.

But I guess this need a little more advertising ;)


This is the only reason I am begging for a tool to generate the
configuration.  The availability of xorg.conf.d doesn't seem to change
this; correct me if I'm wrong.

Julien> My two cents,

Thanks for an informative, snark-less reply.

Basically there are still more than 500 bugs to triage, so I guess
spending time on video drivers bugs is more important than spending time
on user missconfiguration... Especially when the time has been spent to
write the doc already. But the doc might need some improvements, as
always, patches are welcome ;)

Hope this helps,

Bug#617969: xserver-xorg-core: Weird behavior/crash with specific usage

2011-03-13 Thread John D. Hendrickson and Sara Darnell
my experience with that is you *might* have a memory problem with your 
video card


with the lockup statement included that adds to the possibility that 
might be so


on the other hand I can't see it so you might just need graphics libs 
needing to be re-installed


Best is if you can try a "known good" video card in or with the same system.

Alternatively if you can't try a different card maybe you can try known 
good graphics apps that use the same ammount of video memory and see if 
there are problems.  But that is mostly the same as re-installing.


Your not "over clocking" your card are you?  That can cause permanent 
damage.  tools that change clock speed have been known to damage and be 
a pile of bull when it comes to real performance that the card (properly 
set) did not already have.

Package: xserver-xorg-core
Version: 2:1.9.4.901-1
Severity: important

First of all, I am not really sure if this is the package that causes the
problems described below. I have no other clue on which package is resposible.
Secondly, maybe this should be characterized as 'grave'. Furthermore, my
problem can manifest in 2 ways, which seem to be random:

1. A vertical strip of the screen(possibly arround 200pixels wide) from the
leftmost part of the screen gets mirrored/painted on the rightmost part of the
screen. If I just drag my mouse on the rightmost part of the desktop creating a
'selection-rectangle' that portion of the screen gets repainted correctly. This
is the less annoying side-effect. The most annoying is this: If this happens
under GNOME2.x(from unstable) the ENTIRE system lockups. I cannot even
ctrl+alt+f1 to a console. The only thing working is the mouse pointer but I
cannot 'click' anything on screen. My only way to reboot is by
alt+sysrq+r+s+u+b which sucks. If this happens while using Xfce4.8(from
experimental) funnily enough the system doesn't lockup. Everything "works" up
until I close the offending window/program(see below on how to reproduce). But
(in xfce) if I do ctrl+alt+f1-> "sudo /etc/init.d/gdm3 restart" nothing
happens. If after that I do a ctrl+alt+f7 the system lockups again.

2. X.org gets automatically restarted and I get presented with a GDM login
screen. Needless to say everything that was opened on the desktop is lost.

How to reproduce:

1. Use any Gtk program that has a treeview widget with a treestore(eg. exaile,
reportbug, dfeet, emesene) or compile an example gtk-treeview(I did to confirm)
program. Try to approach the mouse pointer to the "arrow" of the treeview that
expands/collapses the rows. The instant the mouse goes over it, one of the
above will happen.

2. Launch xterm. It only paints the window and then one of the above happens.

3. Open LibreOffice Writer and go "Help->About". When the new window opens, one
of the above happens. The same happens when LibreOffice Writer presents you
with a dialog. eg "save/cancel/ignore", "recovering lost work". This may happen
with all LibreOffice products. I haven't tested that.

hi I wrote www.sourceforge.net/projects/xdm-options/

one reason I've used xdm for so long is that having my environment in 
xterm was more important to me than how X got started


I think the C-coded display managers out there don't bother with 
/etc/profile or ~/.profile like a login should - but I don't know.


by the way XAUTHORITY may not be an export when you think it is - and 
maybe it shouldn't be (reasons omitted)


you can use xauth it is simple to use

2011-03-06 Thread John D. Hendrickson and Sara Darnell
of course if you ask and have that command.  just ask I'm actually not 
planning on being in the channel long.  someone might find me!  he he.


Question.  can I ask what top-post is?  I will look it up too.  debian 
rules are getting rather long to even have heard about even having read 
a good part of them once.

Of course.  This is why the kernel driver filters the commands going to
the GPU - the commands come from unprivileged applications (the Mesa
driver is just a shared library) and should not be trusted.

Sounds like more 
than a driver issue but a choice of driver issue.  How are you going to 
have it both ways without an ammount of care you have no time for?


having interrupting access / watchdog is nice if your driver can do that

Don't top-post.

No, not unless it will affect a large proportion of users.


My system locks up whenever I click on a YouTube video link since
yesterday. I can probably live without YouTube :), but in any case this
shouldn't happen.

This isn't a singled out case nor in exotic, possibly faulty, hardware.
It's on a standard 1½-year old Dell OptiPlex 780 desktop with a Radeon
HD card (one of the standard configurations) and this is on a stock
squeeze system.

The findings so far seem to suggest this is a Mesa issue; I'd probably
file it under "Linux kernel bugs" (or even DoS bugs) but I'm not sure
where to properly file such bugs in the post-KMS stack world.

If there is a kernel driver involved then it should be assigned to the
kernel.  Even without KMS, a Mesa driver should be considered untrusted
and should not be able to trigger a crash or hang.  With KMS, this
applies to the X driver too.


With or without KMS, the userspace acceleration drivers can certainly
cause GPU hangs if the 3D engine is programmed with some combination
of commands it doesn't like.


You can't solve the halting problem but you can implement a watchdog,
can't you?

Ben.

Bug#616511: xserver-xorg-video-vesa: Blank screen on ATI R580

2011-03-04 Thread John D. Hendrickson and Sara Darnell
I'll restate the obvious.  note I'm not part of xserver-xorg-video-vesa 
team - so look for more answers.


make sure your linux kernel has radeon support.  make sure X loads the 
modules.  make sure X.org supports the chipset that is actually on the card.

Bug#615959: happens more often

2011-03-04 Thread John D. Hendrickson and Sara Darnell
Johannes could you please tell me if you see this?  I'm unsure if my 
mail is working.


I had the problems you speak of at one time.  I had *thought* my gnome 
were installed but infact the libs were not all installed correctly. 
Was it an installer problem?  I don't remember - but the problem had too 
many details to see in a glance.  I would guess someone already asked 
you to recheck libs.

It seems that this problem isn't just confined to libreoffice. I've also
had it happen with abiword and gimp now, with no particular special
