Today it hit me again when I was switching user. I was logged in as one user, then pressed CTRL-ALT-L to lock the screen and then switch user. After logging in as second user everything was OK. Then I switched back to the first user and then back to the second user and the system was hanging for some time. Also screen was garbled much, thus it is likely to be an nvidia-bug: See also https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers/+bug/1025693
Or is there anybody who is suffering from this without having an nvidia card? Then please leave a comment. [596939.374062] NVRM: os_pci_init_handle: invalid context!
