Radeon Open Source Drivers

[GlacialTurtle]

I could be wrong here, but it could be related to SDL 2. SDL 2 seems like it avoids messing with the actual monitor settings in general on Linux. so e.g. it doesn't actually change your desktop resolution when in games fullscreen, it just creates a fullscreen window and limits the internal rendering resolution (I think). I've noticed other SDL 2 games with broken gamma/brightness controls, so it might be related to that - SDL 2 avoiding changing anything about the monitor settings in Linux (outside of NVIDIA it would seem here).

Maybe look into xrandr? http://www.x.org/wiki/Projects/XRandR/

Also of note that fullscreen borderless doesn't appear on top of the desktop (with Catalyst), unity/compiz still appear on top. Will test it in GNOME under Arch and see if it's any different.

Similar here, I post my problem on Steam forums, but best here, I think. Right now I have:
OS: Debian SID + Mesa 10.6.8 + radeonsi (oss drivers).
Graphic card: AMD ATI R9 290.

The graphics, as you see on the attachment are weird. I can post the hpl.log if needed.

I reply to myself. I have upgraded to Mesa 11 and now it works perfect!

Thanks!

I'm also experiencing issues with the open source amd graphics card with the 3d stuff:





Card: AMD Radeon HD6850
Distro: Arch Linux x86_64
Kernel: 4.2.2-1
Driver: xf86-video-ati 1:7.5.0-2
Mesa: 11.0.2-1
libLLVM: 3.7.0-4

Hi there

I know opensource driver are not officially supported, but i wonder what opengl extensions are required by soma.
I have the same issue as Palmitoxico on an ati hd 4870 using r600g. (mesa 11, 64bit, archlinux)
As my card only supports opengl 3.3 but has the same issue as the 6870, i wonder if the issue is related to missing extensions in r600g.
If someone has some further information/ good guess i would be glad.

There's a bug opened on Mesa bugtracker for this issue:
https://bugs.freedesktop.org/show_bug.cgi?id=92229

I also have HD4870 and the same issue (arch linux, Mesa git)

:-) thanks for the update!

The gamma issue has been a long standing X.org / SDL bug:
https://bugs.freedesktop.org/show_bug.cgi?id=27222
https://bugzilla.libsdl.org/show_bug.cgi?id=971

(It should be fixed in X.org, but I still consider it an SDL bug as well because they could use the Xrandr API which does work - there was even a proposed SDL patch for this in the linked bug report)

Soma stopped working with opensource amd drivers after recent updates. Shows "coludn't init glew" message.

Verify cache integrity and see if that helps.
