Hello. I'm running Scientific Linux 6.2 VM local with an Intel HD Graphic Family driver. I'm running the recommended Resolution setting of 1920 x 1080 outside of SL 6.2. However, within SL 6.2, System > Preferences > Display a) shows 'Monitor: Unknown,' b) the max permitted Resolution setting is 1280 x 768, and c) the 'Detect Monitors' button does nothing.

A better resolution is essential as I am running linux executables that produce displays not fully visible in the terminal window using the current maximum resolution setting of 1280 x 768.

Appreciate anyone's assistance in this matter.

Following are some of the relevant lines from the /var/log/Xorg.0.log file:

I have attempted introducing a /etc/init.d/xorg.conf file to no avail that included:

Section "Device"
Identifier "Device0"
Driver "intelhd"
EndSection

Further, I've seen other threads that suggesting that addition of an xorg.conf file should not be necessary.

Please advise.

switch to using Spice - you;ll get better performance and good resolution
