Public bug reported:
Since linux kernel 3.0(oneric) resolution does not detects correctly. intelfb
can't set correct video mode for framebuffer and Xorg detects the only SVGA
resolutions(max 1024x768) as well. But manually generated ModeLine for Xorg(via
tool cvt) works fine (1920x1080 at 60.00Hz).
I have Core i5 650 and using its integrated GPU. My monitor Samsung SyncMaster
E2220 is connected via VGA(DE-15) socket. I do not have DVI so could not test
this connection.
I was hoped that in 12.04 LTS(or in 3.2 kernel) this will be fixed, but still
it is not.
On Lucid and Natty all works fine.
If you need additional info, please let me know.
