[3.] Keywords (i.e., modules, networking, kernel): -
[4.] Kernel version (from /proc/version): Originally discovered on ubuntu 12.10, but also tested with mainline kernel 3.7 rc7. Currently I'm on Linux version:
3.8.0-030800rc1-generic (root@gomeisa) (gcc version 4.6.3 (Ubuntu/Linaro 4.6.3-1ubuntu5) ) #201212212135 SMP Sat Dec 22 02:36:00 UTC 2012
[5.] Output of Oops.. message -
[6.] A small shell script or example program which triggers the problem (if possible) The problem occurs while connecting the display, in earlier ubuntu versions a much higher resolution was default selected. Manually selecting a higher display resolution is also not possible because higher resolution are not present.
