--- Comment #5 from Alexander von Gluck kallisti5@unixzen.com --- If I disable ColorTiling, Gnome doesn't load completely only showing the desktop wallpaper Errors about unable to find displaybuffer (or something like that... not sure of exact error)
While the display is corrupt.. I *can* tell that acceleration is working due to the speed of the GUI compared to llvmpipe.

attaching related software package versions. A version number means a stable upstream version, a date stamp means that it was a build of the latest git code from that date.

--- Comment #7 from Michel Dänzer michel@daenzer.net --- This is why ColorTiling is still disabled by default for your card... just leave it at that? :)
(In reply to comment #5)
If I disable ColorTiling, Gnome doesn't load completely only showing the desktop wallpaper Errors about unable to find displaybuffer (or something like that... not sure of exact error)
Sounds like a separate issue. FWIW, 'unable to find displaybuffer' sounds like something I've seen myself, though AFAIR without ill effect.

--- Comment #8 from Alexander von Gluck kallisti5@unixzen.com --- Thanks for the input.
I disabled colortiling and installed xfce.. success!
It seems like Gnome 3.6 won't work unless color tiling is enabled. I double checked the gnome session logs and don't see the previously mentioned error anymore.. just a blank desktop wallpaper across both monitors. I erased the gnome config files in .local without any success.
I ran a glxinfo from .xinit, and it does confirm that Gallium is in use. (attached)

Weird. GNOME 3.6 was and 3.8 still is working fine for me with ColorTiling disabled (on a 7770), and I'm not sure how this could be directly related. Is there anything in dmesg about GPU lockups, or is gnome-shell getting stuck somehwere, or something like that?

--- Comment #12 from Alexander von Gluck kallisti5@unixzen.com --- The only dmesg errors are these:

agd5f mentioned that those are normal though. (well, not *normal* but can be ignored)

This means some rendering was dropped on the floor because the kernel ran out of memory. Not sure that can explain it though, unless this keeps repeating it should continue rendering again.

It looks like Jerome Glisse is adding it :)

--- Comment #15 from Alex Deucher agd5f@yahoo.com --- Created attachment 77614 --> https://bugs.freedesktop.org/attachment.cgi?id=77614&action=edit possible fix
Does this kernel patch fix the issue?
https://bugs.freedesktop.org/show_bug.cgi?id=62889
--- Comment #16 from Alexander von Gluck kallisti5@unixzen.com --- I can give it a try, however it may be a few days. I ended up pulling the 7970 and putting it in a box (the cardboard kind) under my desk and replacing it with a 5870 which kind of works minus GPU CP stalls (which i'm opening another bug on :D)
https://bugs.freedesktop.org/show_bug.cgi?id=62889
--- Comment #17 from Alexander von Gluck kallisti5@unixzen.com --- I re-updated my Mesa, llvm-amdgpu, libdrm, to mainline and applied the patch to kernel 3.9.0rc3
Now things seem to be in a better state. The patch doesn't seem to provide any change though as I can boot the older 3.8.x kernel and see the same results.
It looks like something changed in Mesa or libdrm for the better.
Oddly enough, after the updates while Gnome 3 loads ok with color tiling, Steam now shows the corruption Gnome once showed.. (see new screenshot attached)
Sorry i'm kind of all over the place with the testing, I had to update Mesa to get X working again.

--- Comment #19 from Alexander von Gluck kallisti5@unixzen.com --- I can confirm that after disabling ColorTiling that Steam loads properly.
So it looks like:
1) The ColorTiling bug moved from Gnome 3 back to Steam after updating Mesa / libdrm 2) The Patch makes no real difference. 3) Disabling ColoringTiling makes Steam function.
So it looks like things are finally working at this point.
Going to play some random Steam games to see if there is any corruption or CP stalls as with the HD 5870

--- Comment #20 from Michel Dänzer michel@daenzer.net --- Are the 32-bit drivers used by Steam up to date?
https://bugs.freedesktop.org/show_bug.cgi?id=62889
--- Comment #21 from Alexander von Gluck kallisti5@unixzen.com --- Yup. Did the same process for the 32-bit drivers. Same result.
I went ahead and ripped mesa out for Catalyst... which is kind of working. Let me know if you guys have any more big ideas :)

Yup. Did the same process for the 32-bit drivers. Same result.
Works For Me™... Did you verify with LIBGL_DEBUG=verbose that it's picking up the right radeonsi_dri.so?

--- Comment #23 from Michel Dänzer michel@daenzer.net --- With no answer to comment #22, I assume the Steam issue was due to picking up stale 32-bit binaries.
