I am installing 12.04 on an IBM x3250 M2 server. It has an ATI ES1000 with no acceleration (that does not bother me, we don't need it), we use it to connect remotely via FreeNX.
FreeNX works fine, (except than in Windows 7 machines NX Client shows only icons and no text) but the only resolution I can get in the monitor directly attached to the server is 800x600. The display manager also shows me two monitors, the real one and one IBM 15".
Which driver should I install?. It seems that the ATI driver that comes with Ubuntu does not work properly. Any help will be appreciated.
