Public bug reported:
I had a problem for the longest time resolving a resolution issue with
Ubuntu on a Gateway MX3225 laptop. The laptop uses a Via chipset for
graphics. I couldn't seem to get the openchrome drivers working at all
through the traditional methods. I am running Ubuntu 8.10, Intrepid
Ibex with all updates per 1/1/2009.
I installed Mandriva 2009 and configured my xorg.conf and then saved the
file on a flash drive. I then installed Ubuntu, copied the needed
information over to the xorg.conf file, and it worked.
The resolution was set at 1600x1440 or some such resolution (I don't
quite remember right now) right after install. The resolution was also
incorrect when I booted the LiveCD.
Ubuntu does not automatically detect my resolution for this laptop. I
don't know if it's the graphics chipset or not (I'm assuming it is).
Here's the necessary output and information:
