Apparently there are different configurations of the D505. I do not have that UMA option. The first page of the BIOS says:
Video Controller: Intel 855GM/855GME My native screen resolution (with 915resolution) is 1400x1050. -- mouse pointer disappears after switch to console or resuming from sleep https://launchpad.net/bugs/67196 -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
