Red Hat Linux Resolution tuning

Manually generate the xorg.conf file under/etc/x11,

# vi/etc/x11/xorg.conf

The contents of the file are as follows:

# #Add The following codes:

section "Monitor"
Identifier "Monitor0"
VendorName "Monitor Vendor"
ModelName "Monitor Model"
Horizsync 28.0-70.0
Vertrefresh 56.0-75.0
Endsection

section "Device"
Identifier "Card0"
Driver "VESA"
Endsection

Section "Screen"
Identifier "Screen0"
Device "Card0"
Monitor "Monitor0"
Subsection "Display"
Viewport 0 0
Depth 24
Modes "1280x1024" "1024x768" "800x600"
Endsubsection
Endsection

Save and restart, the default is displayed at the highest resolution defined in xorg.conf, which can be modified in the display option.

For example, now it's too big to drive, I'll change the modes to "1024x768" "800x600".
