Summary: [GM965 TV] OpenGL programs crash after switching to
1024x768
Product: DRI
Version: XOrg CVS
Platform: x86-64 (AMD64)
OS/Version: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: DRM modules
AssignedTo: dri-devel@lists.sourceforge.net
ReportedBy: [EMAIL PROTECTED]
- System: AOpen MiniPC MP965-DR
- CPU/RAM: Core 2 duo T7500, 2GB ram
- OS: Fedora 8
- X server: xorg 1.4.99.1-0.10.fc9
- intel_drv.so: built from 12/18 git: f69b48fe24ef9..
- mesa/drm drivers: built from 12/21 git: f8830a1bf788..
- system outputs: VGA, TMDS-1, LVDS, TV
- TV: 32" Sony WEGA, NTSC 480i only
This bug causes opengl programs to hang with 100% cpu usage, and also prevent
any interaction with the X desktop or programs. To reproduce this bug, I did
the following:
1. Boot MiniPC in TV-only configuration with 800x600 resolution
2. Run glxgears (or other opengl program)
- runs without problem
3. Use xrandr to change resolution to 1024x768
4. Run glxgears again
- program locks up after drawing blank black client area, sometimes before
drawing title bar and frame
The system may be restored to functionality by connecting remotely by SSH and
killing the opengl program. However, after this crash/deadlock occurs once,
the opengl program will hang every time it's started, even after switching back
to 800x600. The only way to restore normal operation is to shut down and
restart the machine.
I am submitting this bug to both the xorg/Driver/intel and DRI/DRM_Modules
projects as I'm not sure in which driver the problem lies.
