Bug#441902: xserver-xorg-video-ati: 6.7.192-1~7.2 crashes xserver with xv video playback on compiz

[Alec Robertson]

Hi,

> Do you have a backtrace for this crash? (either at the end of the log,
> or (better) with gdb)

With the latest xserver from unstable, I still get the xv crash. This
backtrace was from vlc playing a dvd then rotating the compiz cube.

Backtrace:

Nope, that doesn't work. Only a "compiz --replace" fixes the problem
(short of restarting X).

Bug#441902: xserver-xorg-video-ati: 6.7.192-1~7.2 crashes xserver with xv video playback on compiz

[Alec Robertson]

Hi Michael,

> I'm following up to the bug report, please do so as well.

I'm not sure what this means, but I'm guessing that I didn't cc the
debian bug report system? I have done so this time.

>> Is 64Gb an acceptable amount for a 128Mb ati card on a 1Gb memory

Turns out it complained with 8Mb but is fine with 16Mb.

> That wasn't tearing but just a page flipping related bug I fixed for
> 6.7.19x.

I have re-enabled page flipping and it seems to be better. There is
still a distortion of my screen when swithcing to/from the virtual
consoles, but this generally goes away after a couple of seconds. If
not, a restart of compiz will refresh the screen. I can file a separate
report regarding this (it has been around for a long time.)

>> As of X.org 7.3, compiz should be faster with EXA than with XAA with
>> the r300 Mesa driver.

Xorg no longer crashes when entering or leaving X, however the EXA
performance is still much poorer than XAA. To be sure, it's better than
it was but there is still a great deal of stuttering when switching cube
faces and even xterm windows do not draw cleanly, resulting in
strange refresh effects. Note that I tried this with the ati driver in
unstable and then in experimental, without much difference between the
two.

Also, I still get these, should I report this as a separate bug?

Bug#441902: xserver-xorg-video-ati: 6.7.192-1~7.2 crashes xserver with xv video playback on compiz

[Alec Robertson]

Hi,

> Is it actually a freeze? Or just the server not restoring the VT console
> because it crashes before doing so (known bug in Xserver 1.4)?

It requires a power off as I have no access to a console/X, but I haven't 
checked whether I can ssh in from another machine. 

> Please try with Xserver 1.4 anyway. You're reporting a bug against a
> package which has never been in Debian so far :/

OK, so I did this two ways:
1) upgrade all packages to experimental -- crashed my system when I
   tried to start X, so I gave up on this!
2) just upgrade: xserver-xorg xserver-xorg-core xserver-xorg-input-kbd
   xserver-xorg-input-mouse xserver-xorg-video-ati... but this has the
   same result, I can't even boot into X and have to hard reboot my
   machine.

> You should try removing all these options.

Is there any reason these would cause problems? Unless I am mistaken,
they break down like so:

* defaults (kept in to be able to switch)
>>Option  "AccelMethod"  "XAA"# XAA (default,fast) or EXA 
>> (slow,buggy)

* required for compiz
>>Option  "XAANoOffscreenPixmaps" # default is undefined 
>> (required for compiz)

* physical parameter for my card
>>Option  "AGPMode"  "4"  # default is 1 (4x=firegl-t2)

* a recommendation I found somewhere (is this necessary?)
>>Option  "GARTSize" "64" # default is 8 Mb

* improve power consumption (I'm on a laptop, does this cause problems)
>>Option  "DynamicClocks""on" # default is off (on=faster?)

* I use radeonfb and the man page says I can turn this off (problems?)
>>Option  "VGAAccess""off"# default is on (not required 
>> for radeonfb)


> You should try EXA instead of XAA too (especially with Xserver 1.4).

I've been trying this on and off, but with my compiz desktop, EXA is
terribly slow to draw the windows.

Bug#441902: xserver-xorg-video-ati: 6.7.192-1~7.2 crashes xserver with xv video playback on compiz

[Alec Robertson]

Package: xserver-xorg-video-ati
Version: 1:6.6.193-1
Severity: normal

I'm running unstable but with the latest experimental ati driver from 
bgoglin that works with the xserver in unstable. Version 6.6.193 works 
fine with xv video and does not crash the xserver when I switch desktops 
in compiz (composite + aiglx + r300). But it does have problems switching
back and forth from virtual terminals, so I have to disable pageflip. 
6.7.192 fixes this virtual terminal problem, but when I'm playing videos
with mplayer (or vlc) and I switch desktops then the xserver crashes.
I've tried upgrading the necessary xorg components to 7.3 but this
freezes my system when I exit the xserver with ctrl-alt-delete,
requiring a hard reboot.
