I have installed Debian yesterday. Later I installed the AMD Catalyst Driver because the system didn't detected the second screen. It worked perfectly.Now I can't launch gnome-control-center, I don't know if it's related to the AMD driver. Anyway it only displays these errors:~> gnome-control-center*** glibc detected *** gnome-control-center: free(): invalid pointer: 0x00007fd97191ae88 ***======= Backtrace:

Can't launch gnome-control-center, fglrx problem?
debian;gnome shell;fglrx
The dependencies linking Debian packages ensure that you can't break one package by uninstalling others, unless you force things. So if the gnome-control-center package is still installed, that means that all its dependencies are still there too.Given that the fglrx driver was installed from the binaries provided on AMD's web site, it doesn't have the same guarantee. If you can, I would suggest uninstalling fglrx with sh ./amd-driver-installer-[version]-x86.x86_64.run --uninstall and verifying whether gnome-control-center works without it (using the radeon driver).Once that's determined, you can reinstall fglrx, perhaps using the packages available alongside Debian in the non-free repositories (start from the fglrx-driver package; you may need to add contriband non-freeto the lines ending with main in /etc/apt/sources.list). Complete instructions are available on the Debian wiki.
