Demonstration of X server / OpenGL lockup with Haswell graphics
Some, but not all, combinations of various X and OpenGL programs running on
Haswell built-in graphics (using the "intel" video driver) can cause the X
server to lock up solid, no response from the mouse and no ability to switch to
a virtual terminal.
The system used is an HP prototype with Haswell CPU and Lynx Point PCH.
Attached you find a shell script that runs programs found in the xscreensavers
package that installs by default. This script typically yields the lockup
within a few minutes. It does create a window that is 1280x1024, so won't run
as is on lower resolutions. If you modify it, the principle is that the two
smaller windows should lie within the larger one, in the vertical dimension.
Driver stack is:
- xorg-server 1.6.5
- xf86-video-intel 2.21.4
- Mesa-9.0.3
- libdrm-2.4.41
- Kernel is from Daniell Vetter's git branch
(git://people.freedesktop.org/~danvet/drm-intel)
