after upgrading from 15.1 -> 15.2 I’m running into problems with my X11 hardware acceleration. In /var/log/Xorg.0.log I can see the following error message:
"intel(0): Failed to submit rendering commands (Operation not permitted), disabling acceleration"
The message indicates, that it is somehow related to permissions - does anyone has an idea ?
I noticed that the error message is not coming from the startup - it happens once I start an application using OpenGL like glxgears.
After that my system is an questionable state, screen updates in spotify do not work properly anymore and firefox starts hanging for a minute when scrolling.
