    Having a different issue and need some help. My machine works fine in windows environment with no display issues. I loaded Ubunu 10.4 and now have a split screen going on. Tested the drivers again using a windows rescue disk and no issues with lcd or card. Any ideas? Could it be the system bios. I checked the iso and no problems with the disk. Any ideas would be appreciated.

    Thank you very much!

    When resolution was 800×600 there were a kind of “vertical lines” on the left of desktop (like points).

    Now I have made what you say, this issue is fixed and I have the right resolution for this laptop

    Thanks again!
