Hi,

where does this in your xorg.conf come from?

Section "Files"
        ModulePath "/usr/lib/xorg/modules/extensions"
        ModulePath "/usr/lib/xorg/modules"
EndSection

I don't know offhand where it came from; either it was added automatically by an
fglrx installer which generated an xorg.conf file (before fglrx was properly
packaged), or I added it by hand during my initial system setup because it was
actually necessary at that point.

Delete that block and move everything back to its original location. That
should fix your issue.

Yes, that gets me into X with functioning GLX, albeit with possibly lower
performance; I seem to recall getting ~6400 FPS from glxgears under the
manual-symlink solution, and now I'm getting only ~3000-~3200. That could be a
coincidence, though; if I see perceptibly worse performance in software where it
actually matters, I'll try to revert to the manual-symlink configuration and
test.

I don't think you need to do the debugging I described here:

I would think probably not, no. I could switch back to the problematic config
and do it if you want, but it doesn't seem necessary.

/usr/lib/xorg/modules/extensions/libglx.so ->
/usr/lib/fglrx/fglrx-libglx.so

If you delete the link - does it work? It should pick up linux/libglx.so

With the existing xorg.conf, no, it does not. With the Files section commented
out, yes, it does.


Thanks for the quick solution!
