I have similar troubles. The freezes were less frequent when I upgraded to kernel 3.4.0-030400-generic but they still occur.
I'm running a GeForce 6150 LE and "dkms status" says: nvidia-173-updates, 173.14.35, 3.2.0-30-generic, x86_64: installed nvidia-173-updates, 173.14.35, 3.4.0-030400-generic, x86_64: installed dmesg ends with: [ 3361.843042] NVRM: Xid (0000:05): 9, Channel 00000000 Instance 00008069 status 0000001d [ 3361.844898] NVRM: Xid (0000:05): 9, Channel 00000020 Instance 00000000 Intr 00100000 Is there anything we can do to help troubleshoot this? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1027724 Title: [nvidia] Xorg freeze To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers/+bug/1027724/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
