I have been able to solve the problem, thanks to an Ubuntu forum post. However, it might still be a bug, since not everyone will find the solution.
The problem was that the ATI flgrx driver failed to load with kernel -16, as of the time I originally posted this bug. But flgrx still worked in kernel -15. Using kernel -15, hardware manager, I disabled the ATI restricted driver. Using synaptic, I obtained the envyng package and its GUI. From terminal, I used sudo envyng to download and install a new ATI graphics driver. Then I re- booted to kernel 16. At first, it was in the wrong resolution. But I enabled the new ATI graphics driver and re-booted again. All was well. Someone suggested that afterwards, it helps to re-install compiz. I don't know. -- compiz.real crashed with SIGSEGV https://bugs.launchpad.net/bugs/216043 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
