This problem of "vertical coloured lines on bootup dell inspiron 1501" still presents with 14.04. I just upgraded from 12.04 to 14.04, in the upgrade process the fix of adding radeon.nomodestet=1 at grub bootline got lost, and the vertical colored stripes came back when booting up. However, it seems that it seems it happened not as often.
I wish that the problem could be fixed. My laptop is a Dell INspiron 1501. I read in the list that it has related to Unity? Is it true?
