"Can you activate compositing?"
How to do that please ?

I don't know how you can activate compositing on Kubuntu. I activated it on ubuntu MATE 14.04.1 LTS with MATE Tweak on my Intel Mac last week.

Do you use the unofficial Mesa system-wide? Can you activate compositing?
Of course, like I showed here (http://forum.hyperion-entertainment.biz ... 847#p31858) I followed your guide and exectuted the Mesa procedure twice. Video and games are correct. I can't get compositing to work - not Compiz nor Compton. I don't know if the somewhat transparent window decorations are indicative of compositing enabled or are a part of Metacity and Openbox.

Hi All,

I read that Mesa 10.5 is faster with a Radeon HD6870 than the older Mesa versions.

Link: Ubuntu 15.04 Offers Faster OpenGL For AMD Radeon GPUs On Open-Source

Therefore I patched it because of the wrong colors problem and compiled it on my AMIGA one X1000 today. I tested the new Mesa 10.5.4 with 'glxgears' and with SuperTuxKart 0.8.1 on Debian Sid. Unfortunately STK is slower with the new Mesa. At least 15% slower than with the unofficial Mesa 10.0.4. 3D acceleration works but slower on Debian Sid.

The unofficial Mesa 10.0.4 is used on some Power Macs and on the AMIGA one X1000 because all new official Mesa versions on Linux PPC have wrong colors.

Rgds,

Christian

Hi All,

I compiled Mesa with LLVM 3.7 because of the following news:
There are numerous improvements to the PowerPC target in this release:
  • LLVM now generates the Vector-Scalar eXtension (VSX) instructions from version 2.06 of the Power ISA, for both big- and little-endian targets.
  • LLVM now has a POWER8 instruction scheduling description.
  • AddressSanitizer (ASan) support is now fully functional.
  • Performance of simple atomic accesses has been greatly improved.
  • Atomic fences now use light-weight syncs where possible, again providing significant performance benefit.
  • The PowerPC target now supports PIC levels (-fPIC vs. -fpic).
  • PPC32 SVR4 now supports small-model PIC.
  • Experimental support for the stackmap/patchpoint intrinsics has been added.
  • There have been many smaller bug fixes and performance improvements.

I just tested Mesa 10.6.2 on Xorg 1.16.4-r2. Result:

32-bit root window: No matching fbConfigs or visuals found
16-bit root window: Wrong colours (red and blue swapped)

@xeno74: Do you still have the patch you used on 10.5? I can try applying it on 10.6 and see if it fixes the colours at least.

Hi Marcus,

Thank you for testing Mesa. :-) The patching of Mesa because of the wrong colors is very easy. You have to modify the file p_format.h in the directory src/gallium/include/pipe/. In this code block you see the patched part of this file:

Good luck. :-)

Thanks.

That fixed the colours in some apps (e.g. glxgears is ok now), but not in others.

Oh well...

(I tested with the r600 driver (on TURKS) btw.)

Nice. The first patch in the series looks interresting too, it might fix the cases which your patch did not.
