Hi,
I am stumped and was hoping somebody my help me.
Just installed 11.04 on a box that it is on a kvm switch. As long as the switch is connecting the monitor to the booting Ubuntu box, the resolution of the monitor is detected OK. However, if for some reason I am working on a different box and the KVM switch is routing K V and M inputs to the other box, then Ubuntu defaults to what seems a botched VGA setting (i.e. it chops off top and left sections of the display).
While in this "VGA" mode if I log out and log in, it re-detects the resolution ok.
Is there any way to force Ubuntu to use a specific resolution no matter what? In this way, if I am working on a different box while waiting for Ubuntu to load, when I switch the resolution will be OK.
I tried the only thing I can think of and this is to set the "good" resolution as "default" for "all" monitors, but it has no effect.
Somebody suggested to edit x.org.config.
I checked http://www.x.org/wiki/ConfigurationHelp
and tried X -configure as indicated in the wiki to get X to generate its configuration file. I figure, there should be a setting somewhere to prevent autoconfiguration, but all I get is this error message:
=================
peter@DELL-PC:~$ sudo X -configure
Fatal server error:
Server is already active for display 0
If this server is no longer running, remove /tmp/.X0-lock
and start again.
Please consult the The X.Org Foundation support
at http://wiki.x.org
for help.

Any ideas would be very much appreciated!
FYI, my box does not support Unity and hence it runs in Classic
