--- Comment #21 from Michel Dänzer michel@daenzer.net --- (In reply to Vladimir Ysikov from comment #20)
I rebuild llvm-svn, mesa-git with debug symbols and get this:
behem0th@ArchLinux ~ $ glxinfo name of display: :0 Error: couldn't find RGB GLX visual or fbconfig
Looks like something went wrong when updating LLVM / Mesa. Please attach the corresponding Xorg.0.log file.
