Everything renders OK now. Also I managed to crash a kernel :) Here is corresponding /var/crash/vmcore.0 file: https://dl.dropboxusercontent.com/u/19923518/temp/vmcore.0.tgz Hope this is a file you need since I'm not a kernel developer and wiki says something regarding core.txt.* which I don't have. I didn't manage to find exact steps to reproduce a crash but after running an application for a while, resizing windows, switching desktops, enabling/disabling wireframes mode (X button) etc it reproduces regularly. Another problem I found is that everything renders OK when I run application using sudo: http://imagizer.imageshack.com/img923/8076/VoUVVt.png But when I don't use sudo there is a lot of artifacts and FPS is only about 15 instead of 60: http://imagizer.imageshack.com/img924/8987/L71OjT.png > It seems it fails to open the drm device.

I'm afraid I don't have such a group: ``` sudo pw group mod video -m eax pw: unknown group `-1' ``` On Sun, 14 Feb 2016 19:49:06 +0300 Eax Melanhovich <afiskon@devzen.ru> wrote: > Hello, Michael > > > The WIP kernel driver instructions are here: > > https://wiki.freebsd.org/Graphics/Update%20i915%20GPU%20driver%20to%20Linux%203.8 > > It works!
