IT@School GNU/Linux Display Problems

If you cannot get Graphical Desktop, or gets a blank screen,

go to virtual console 1 by pressing Control + Alt + F1 login as root user and

issue the command,

dpkg-reconfigure xserver-xorg

then follow the instructions. Use tab to switch to ok cancel buttons and enter key push the ok/cancel buttons. After completing the configuration, you will be back to root prompt ie #.

Use the command,

/etc/init.d/gdm restart to restart the xserver.

Things to note while reconfiguring the xserver

1. In most cases, the graphics card will auto detect by the system. If still not getting display after configuration is completed, Check your mouse. If it is a serial one, you have to select /dev/ttyS0 or /dev/ttyS1 as the mouse port and select the protocol as microsoft.
2. In configuring monitor, select Simple option and choose the size of your monitor form the list. Also make sure that the resolutions 1024x768 800x600 and 640x488 is selected (stared *). If there is no star(*) on it press space to select the option.
3. In the Video memory option make sure you choose atleast 8192 (8MB of Video ram)
4. Still the graphics is not working choose the driver as VESA
