Bug#543802: xserver-xorg-video-ati bugs when blender rendering
Package: xserver-xorg-video-ati
Version: 1:6.6.3-2 (etch) to 1:6-12.2-3 (lenny/unstable)
Following blender tutorial "Manual - Blender 2.43 Part I"
(http://wiki.blender.org/index.php/Doc:Manual/Your_First_Animation/1.A_static_Gingerbread_Man),
in chapter "Lets's see what Guss looks like (rendering)", making both
layers 1 and 10 visible, and so moving a bit the drawing: server X
freezes...
Mouse pointer can move but clicks and keyboard do nothing (impossible to
change screen, to stop the server or halt the system: no input).
System seems to be alive yet because an "at" job like "halt" launched
before the "freeze" will stop the system.
I tested in stable and apt-pinning, all with xfce4 desktop manager:
- Debian Lenny with the 2.46 blender version
- Debian Lenny with 2.48 blender version (testing)
- Debian Lenny with 2.48 blender version + xserver-xorg-video-ati
1.6.12.2.2-3 (unstable)
all with both my costumized and generic 2.6.26 kernel
- Debian etch with blender and xserver-xorg-video-ati stable
version with generic 2.6.18 kernel
In all the above cases the same problem.
I installed the ATI proprietary fglrx driver and module in the same etch
configuration and all works fine without problems.
That is the reason why i think it's driver bug, not a blender or mesa bug.
I cannot test fglrx in lenny because my graphic board is based on ATI
Radeon 8500 and fglrx for lenny does not suport this chip.
All tests have been done with the same xorg.conf bellow:
I can do more tests you need
thanks
