Hi all
After upgrading my Ubuntu from 10.04 to 14.04 I only see the upper left
detail of the whole screen.
In the Xorg log file I found that the mode was probed to 1024x768
instead of 640x480.
Then I found a suspicious error message from the kernel that could be
the cause of the failed mode setting.
Is my assumption correct?
