Solution: sudo rm /usr/lib/xorg/modules/libglx.so && sudo cp /usr/lib/xorg/modules/extensions/libglx.so /usr/lib/xorg/modules/
The problem was, that libglx.so in /modules directory was a symbolic link to old 180.44 glx library but this in /modules/extensions was correct. -- Error: couldn't find RGB GLX visual or fbconfig https://bugs.launchpad.net/bugs/433522 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
