unknow monitor & screen is not refreshed
I installed Ubuntu 9.10 on an old PC, Dell dimension L550r, PIII500, 512M ram.
There is a problem that monitor is not detected. I could logon as 'xterm' type, but the window size is only 1/4 of screen. When I logon as 'GNOME', it seems screen is not refreshed. media player window is blank, but can see a static image if minimize and restore window. Even terminal window is blank.
Go to "System"->"Preference"->"Display", shows "monitor unknown"
I can not find file /etc/X11/xorg.conf, is this normal?
xrandr command output:
Screen 0: minimum 640x400, current 1024x768, maximum 1024x768
default connected 1024x768+0+0 0mm x0mm
1024x768 60.0* 75.0 70
Any help is appreciated.
