I doubt any changes that you make to the 'virtual' will matter.

It's clear that your setup is trying to configure 'on the fly' and it
may prove useful to actually configure a video card section in xorg.conf

It would use 'radeon' module. You have 32 Megabytes of video ram which
will easily handle a hefty size screen.

I would suspect that something similar to 'system-config-display
--reconfig' is available on Ubuntu to write the configuration for you.

Perhaps something like... 'sudo /usr/bin/X -config' will do it.

I am sorry but I am not knowledgeable about Ubuntu utilities.
