Installing Feisty On 6400/1505 With Script
Initial Install and Preparation
Download the Ubuntu Desktop Live CD from Here: Download ISO Here. Burn the ISO to CD and boot.
After booting into the CD X won't start. Hit Enter to say OK to the error messages and get back to the black screen. You may need to switch to ALT-F4. Do the following, one at a time, to get X working:
sudo chmod +x ati
You'll see X start and you are now running the Live CD in your native resolution!
Double click the Install icon and configure your install how you like it.
After your system finishes installing it will prompt you before rebooting, ensure you have a network cable connected, and when it boots into the new system you'll see an error about X. Use your arrows to select NO, hit ENTER and then OK to get to the black login screen. You'll see an error regarding BCM43xx appearing, ignore it and type as if it wasn't there. The command line can't "read" that error so don't try to backspace over it, etc. Login using your username and password.
Download the script
Make it executable and run it:
sudo chmod +x dellinstall
Sit back and relax for a moment until you hear your system BEEP at reboots.
After the system reboots X still won't start, login to the black login screen (X still errors out), go into the install (cd install) directory and again type the same script command:
When it is finished the system will BEEP, reboot, and you can now use it!
Your system will reboot automatically and after it comes up you'll have X. To login to Beryl, before you login select the GNOME with XGL session from the Options>Sessions menu in the bottom left corner.
