Messed up colors, Radeon driver, Radeon 6950 Cayman GPU

[newjerseyninja]

Hello,

I am using Mint 18.1 and have a Radeon 6950 card. This is a Cayman GPU.

Kernel is the one that came with the OS:
4.4.0-53-generic


I used the Oibaf PPA and upgraded to what I thought was the latest:

This is what glxinfo gives:

OpenGL vendor string: X.Org
OpenGL renderer string: Gallium 0.4 on AMD CAYMAN (DRM 2.43.0 / 4.4.0-53-generic, LLVM 3.8.0)
OpenGL core profile version string: 4.1 (Core Profile) Mesa 12.0.6
OpenGL core profile shading language version string: 4.10
OpenGL core profile context flags: (none)
OpenGL core profile profile mask: core profile


When I start up War Thunder, I am getting insane bright colors, looks like a highlighter marker exploded on the screen.



What should I try next to fix the colors?

The game actually runs pretty smooth.

Apparently I wasn't yet running the Oibaf stuff when the colors were messed up originally.

After getting all of that installed:

$ glxinfo | grep OpenGL
OpenGL vendor string: X.Org
OpenGL renderer string: Gallium 0.4 on AMD CAYMAN (DRM 2.43.0 / 4.4.0-53-generic, LLVM 4.0.0)
OpenGL core profile version string: 4.1 (Core Profile) Mesa 17.2.0-devel
OpenGL core profile shading language version string: 4.10
OpenGL core profile context flags: (none)
OpenGL core profile profile mask: core profile
OpenGL core profile extensions:
OpenGL version string: 3.0 Mesa 17.2.0-devel
OpenGL shading language version string: 1.30
OpenGL context flags: (none)
OpenGL extensions:
OpenGL ES profile version string: OpenGL ES 3.0 Mesa 17.2.0-devel
OpenGL ES profile shading language version string: OpenGL ES GLSL ES 3.00
OpenGL ES profile extensions:




The colors are actually worse now.


Oddly glxgears runs perfect.

Mint uses really old, slow and buggy software and your Oibaf is really old, currently it uses llvm 4.0. Use a rolling release distribution like Debian testing Xfce and Oipaf ppa yakkety version from launchpad, see the second message:

I purged my existing oibaf ppa and switched to the Padoka mesa PPA.

Same performance... colors are still all messed up:

$ glxinfo | grep OpenGL

As soon as the moderator here lets me post a picture of it I will.

I have tried min, max, medium settings and its all the same, no effect on the crazy colors.

I will try a newer kernel. I can get a 4.10 series kernel that is a binary. I am less comfortable compiling a kernel.

The game itself is a linux steam game.

Previously this all worked OK on a 14.04 based Mint 17.0 with 3.11 kernel running Fglrx driver. I only "upgraded" because after about 6 months of working perfectly the game just stopped working. Thats when I started reading about the new drivers, upgrade distro, etc.

Messed up colors are probably a mesa issue. I'd suggest trying a different version of mesa.

I have been using the latest Padoka PPA for MESA for the past 3 months, the performance actually got less stable. Now the game freezes very often, most of the time it is recoverable by using alt + tab to switch contexts. When returning to War Thunder the game is unfrozen.

The graphics are still very messed up.

I've seen references to the GPR Limit needing to be 128 instead of 124 as is set in r600_shaders.c

This problem seems to be several years old. Is there any chance this will ever get fixed? I really don't want to have to install a windows partition just to play a game.
