Cool! That lets me select whether to use the -386 kernel or the -generic
kernel as default - thanks.
@Chris: use the following to set for your specific monitor:
Log off and then log back in. Once you've done that:
gksu gedit /etc/X11/xorg.conf
and modify the "Virtual" settings this section to your proper screen
settings (1600 1200):
Identifier "Default Screen"
Device "Configured Video Device"
Monitor "Configured Monitor"
Virtual 1024 768
Test that first (logout/login), and then you may also wish to modify the
depth settings as well depending upon what grapic card you have - I've
found on certain Intel & ATI cards, setting to 16 instead of 24 enables
dri and speeds up my glxgears on those cards by a factor of about 2.
