How to Fix Screen Blank when Installing openSuSE 10.3 on Eee Box


openSuSE installed from the DVD successfully, but the screen would go blank and enter standby mode after booting. A DVI-VGA adapter was used to connect a VGA LCD screen.

The problem lies in the Xorg configuration. Apparently the default Intel driver does not work. The driver needs to be changed to VESA.

To fix the screen and get Xorg to work correctly:

1.      Turn on the computer. It will display the boot progress, but then the screen will go blank. Press Ctrl+Alt+F1 to change to command line mode.

2.      Login as root.

3.      To edit the configuration file, you will require a text editor. By default, only vi is installed. These instructions use pico. To install pico, place the openSuSE Install DVD in the drive, and type “yast2 –i pico” on the command line.

4.      Open the configuration file: pico /etc/X11/xorg.conf

5.      Scroll down using the arrow keys to find the line which says:
Section “Device”
A few lines futher down, replace this line:
Driver    “intel”
With this line:
Driver    “vesa”

6.      Press Ctrl+O and then Enter to save the file. Press Ctrl+X to exit.

7.      Type “reboot” to restart the computer. This time you should be able to login to the desktop environment as normal.
