I have an ATI Radeon HD 4770, using Natty x64 and the open source ati drivers.
I'm having some trouble with graphics, and I'm stuck in software rendering mode.
As you can see, the r600 dri is failing somewhere and it is falling back to the software rasterizer. I didn't have this problem before Natty, but now I just can't seem to fix it. I've googled around and there's not too much info out there, but it was able to get me this far, and it seems that there may be some problems with the r600 and KMS, according to this page:
:~$ LIBGL_DEBUG=verbose glxinfo|grep render
libGL: OpenDriver: trying /usr/lib/dri/tls/r600_dri.so
libGL: OpenDriver: trying /usr/lib/dri/r600_dri.so
libGL error: failed to create dri screen
libGL: OpenDriver: trying /usr/lib/dri/tls/swrast_dri.so
libGL: OpenDriver: trying /usr/lib/dri/swrast_dri.so
direct rendering: Yes
OpenGL renderer string: Software Rasterizer
But now I am at an impass, because I am not all that versed in linux, and I don't know what the next step is. That bug report seems to imply that this can be fixed, but I don't know what to do. Can anyone help me?
