Other things I've tested that didn't help: Updated the following packages to the versions in experimental:
- libegl1-mesa 17.0.3-1 - libgbm1 17.0.3-1 - libgl1-mesa-dri 17.0.3-1 - libgl1-mesa-glx 17.0.3-1 - libglapi-mesa 17.0.3-1 - libgles2-mesa 17.0.3-1 - libwayland-egl1-mesa 17.0.3-1 -- reverted back to stretch -- Updated the following packages to the versions in sid: - gir1.2-mutter-3.0 3.22.4-1 - libmutter0i 3.22.4-1 - mutter 3.22.4-1 - mutter-common 3.22.4-1 -- reverted back to stretch -- Meanwhile, the system running stretch with UXA has not shown this issue for over three days now. (Normally it happens every couple of minutes.) /etc/X11/xorg.conf.d/20-intel.conf: Section "Device" Identifier "Intel Graphics" Driver "intel" Option "AccelMethod" "uxa" EndSection I am uncertain if this happens on newer Intel GPU's as well, because I don't have any. I may have some i945 boards with a GMA 950 that I could test later. What I have tested, is a GeForce GT220 with the nouveau driver on a G41 board. I could not reproduce this bug there. -- With kind regards, Kevin Keijzer GNU/Linux systems administrator, LibrePractice https://www.librepractice.org/
