there is a distorted graphics problem if you are Red Hat Enterprise 5 Edition on Microsoft Virtual PC 2007 running on Windows 7(I am using the Professional Edition)
you need to modify the X Server configuration file and change the default display depth to 16 bits
most Linux distributions support 24 bit colour,
which MVPC doesn't support(only 16 bit colours)
ALT + F2
type gnome-terminal ans press RUN
[root@localhost ~]#ls -ltr /etc/X11/xorg.conf
[root@localhost ~]#vi /etc/X11/xorg.conf
change the following..
Section "Screen"
Identifier "Screen0"
Device "Videocard0"
DefaultDepth 16
SubSection "Display"
Viewport 0 0
Depth 16
EndSubSection
EndSection
