Description Philipp Brüschweiler 2012-09-05 20:29:06 UTC

When running latest weston on DRM, the keyboard and mouse completely lock up and the display is filled with junk/random textures from the past. Not even sysrq+rv gives back control of the keyboard. The only action left is to force a reboot (sysrq+reisub or hard reboot).

I have not been able to produce interesting log output, or even a crash log (which means that the problem doesn't seem to be a simple segfault). Log with all the env variables in wayland.freedesktop.org/building.html (under "Notes") set: http://www.hastebin.com/raw/yumicikeru
