I fix the dependency problem. I had to remove all the nvidia packages and install the modalias packages and the nvida-common. I installed 195.22 and the problem is back. flash-flash then login screen. Therefore the problem must be in the nvidia accelerated server as the NV, non-accelerated work fine.
This morning I had an update on nvidia 195.30. I just installed it and hoping this may fix the problem. -- Random full screen flash then xorg-server crash back to login screen https://bugs.launchpad.net/bugs/497954 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
