[gentoo-user] urgent : chicken-egg problem

[Helmut Jarausch]

Hi,,

somehow one of my machines is broken.

After uninstalling x11-drivers/ati-drivers 
eselect opengl set xorg-x11
gives
Switching to xorg-x11 OpenGL interface...!!! Error: No proper xorg-x11 or xorg-x11 opengl implementation found

Trying to re-emerge media-libs/mesa fails during install
Switching to xorg-x11 OpenGL interface...!!! Error: No proper xorg-x11 or xorg-x11 opengl implementation found
exiting

and trying to re-emerge x11-base/xorg-server
fails because of missing file
/usr/lib64/libGL.so

So, how can I cut this Gordean knot?

Many thanks for your help,
Helmut.

If the ati-drivers are like my nvidia drivers you many have a dangling
symlink at /usr/lib/libGL.so:

/usr/lib/libGL.so  <----- This is a symlink to one of the two libs below
/usr/lib/opengl/xorg-x11/lib/libGL.so
/usr/lib/opengl/nvidia/lib/libGL.so

Try pointing that symlink to the opengl version of libGL.so.

Thanks, this helped. I ran symlinks -dr on /usr
Initially this didn't help.
Once I've stopped the X server, I could re-emerge mesa which
fixed the problems.
Many thanks again,
Helmut.
