Comment 1 Hadrien Grasland 2012-10-29 11:05:43 UTC

I plugged in an LCD monitor (ASUS PB238) on my laptop, then used the Fn-based keystroke to switch graphic outputs, and multiple errors like this appeared. The operation was successful in the end, though.

Package: kernel
Architecture: x86_64
OS Release: Fedora release 16 (Verne)
