source code of modified glxgears
Attached a hacked version of glxgears:
Main modifications (just quick hacks):
- force frame rate divided by 2 (if 60Hz monitor 30fps)
- force run only if desktop resolution is double the width one of typical
resolutions (for example 1920*2 x 1080 or 1600*2 x 900 ...)
- undecorated, stay on top window. No fullscreen hint as it would make go to
only one monitor, problem with some window managers the panel/menu bar is
visible (deactivating page flip)
- textures generated by program with alpha channel to "stress test" and more
gears.
Build with
gcc -o "glx_swapbuf_test" ./glxswapcontrol.c -lm -lX11 -lGL -lGLU
Time to hang can be as much as 2 days usually less than 1 day.
Last hang with kernel
linux-image-4.3.0-994-generic_4.3.0-994.201511052100_amd64 both with and
without drm debug enabled.</pre>
