Recently i tried to upgrade my laptop from Ubuntu 9.04 to 9.10. Generally this is pretty straight forward, just a few clicks and it's done and running better than ever, however, this time was different.
The upgrade went fine then it was time to reboot. After the BIOS POSTed and the ubuntu kernel started loading all i could see was a white screen with vertical lines that grew in intensity as time went by.
After looking for a solution for a long time i decided to just format the drive and install 9.04 again. The next day i found a posting about a possible solution so I had to check it out and finally got Ubuntu 9.10 installed.
At https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/... (comment 94) there was a comment asking someone to try putting "nomodeset" as a boot parameter.
With the Ubuntu 9.10 Install CD at the options screen after highlighting the install option you can press F6 to add more boot options. Adding the "nomodeset" allowed it to install but after rebooting it was still having issues with the white screen.
The solution is to edit the /boot/grub/grub.cfg file and add the "nomodeset".
On line 53 there is a line:
that needs to be modified to:
After all this I finally have a working system.
