I have a HP mini note 2133, with 1024 x 600 resolution screen.
There were some issues with the wireless network (broadcom) card not working on the system, on ubuntu 9.10 I could not get the wireless card to work at the same time as the broadcom card.
When I installed the system the screen worked fine but as soon as I installed the driver for the network card the screen stopped working.
The problem was not that hard to fix though.
1. Stop gnome display mangager
sudo service gdm stop
2. Configure xorg with a xorg.conf file
sudo Xorg -configure
Move the xorg conf file to /etc/X11/xorg.conf
I added this line to the Devices section
Option "PanelSize" "1024x600"
3 Start GDM
sudo service gdm start
4 Install the driver for the network card
After that it worked fine and I have a bit more understanding about linux.
