Could not apply the stored configuration for monitors

Hi, I have an Esprimo Mobile laptop. I have upgraded Suse 11 to 12.3 by installing the new OS and keeping the home directory.

I am facing the problem that the monitor is not compatible with the setting I got after the installation. The resolution is bad, and in the command mode (Ctrl+Alt+F1), when running MC commander, the screen is confused and unreadable.

I obtain the following warning message in graphical mode after each booting:

None of the selected modes were compatible with the possible modes
Trying modes for CRTC 320
CRTC 320: trying mode 640x480@73Hz with output at 1280x768@76Hz (pass 0)
CRTC 320: trying mode 640x480@73Hz with output at 1280x768@76Hz (pass 1)

Please help for establishing the good monitor setting/device.
