- title ATI X700 Mobility Graphics Chipset
Ubuntu 7.04 (Feisty Fawn)
Some users using the ATI x700 Mobility graphics card on their laptop may find that there is no display after installing Ubuntu. The default driver "ATI" does not support this card correctly. The driver therefore must be changed. Note: If you plug a secondary monitor into your system, you will find that you can see the gnome login prompt on that monitor.
Step 1: Closing Gnome and logging in
When your system has turned on, and you hear the Gnome login sound, Press the Ctrl-Alt-F2 keys at the same time. You will now be shown the login prompt, login using your user name and password that you setup when installing Ubuntu. (Note, don't worry when inputting your password, the display never shows how many digits it is (and so no "*" are displayed). You have now logged into your Ubuntu installation.
Step 2: Opening The Xorg File
Open up /etc/X11/xorg.conf which is the config file for Xorg.
Step 3: Changing The Driver
Using your arrow keys scroll down until you see something similar to...
Section "Device" Identifier "ATI Technologies Inc Radeon Mobility X700 (PCIE)" Driver "Ati" Bus "PCI:1:0:0" Endsection
...and then change the driver value "ATI" to "vesa".
Step 4: Restarting The Machine
You may now restart you computer for changes to take effect.
Step 5: Logging in
You should now be presented with the Gnome login screen (yay!) Type in your details and login to your Ubuntu system.
Step 6: Installing The Restricted ATI Driver
This step is optional, however it is likely to improve your graphics performance. If you are using Ubuntu 7.04 Feisty then Go to System>Administration>Restricted Drivers Manager and then enable the driver. Note, this requires an active internet connection
