Christopher, based on your question, I added NOMODESET to /etc/default/grub definition of GRUB_CMDLINE_LINUX_DEFAULT, ran update- grub, and rebooted.
Short answer - it no longer provides any salubrious effect. Long answer: The system booted into stripey / herringbone display, though there were some pure-white patches interspersed with the herringbone pattern. I closed the lid, waited a moment, and opened it, and the display appeared to be in a lower resolution mode. I logged in and checked; sure enough, it was in 1024 X 768 rather than 1280 X 800, and I could not select that higher resolution mode in screen settings - it was not offered. Also the video performance was v e r y s l o w. So I removed the NOMODESET and rebooted. I guess today is a good day for rebooting as I did not get the herringbone / stripey pattern on this boot. One other odd effect I have noticed. If the system boots into SHM (stripey herringbone mode) and I correct it by closing the lid and reopening it again, subsequently after screen blanking the screen reappears in SHM. I don't recall this behaviour in the past. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1234429 Title: 1002:5975 [Dell Inspiron 1501] vertical coloured lines / herringbone pattern on startup Status in “linux” package in Ubuntu: Incomplete Bug description: This problem occurs intermittently on my Dell Inspiron 1501 laptop. For instance, on booting the Saucy beta 2 release from USB stick; or today, booting the installed 13.10 beta 2 with all updates current. But not always. The screen is 100% illegible when this happens. WORKAROUND: Wait for the screen to blank on power save; when it is reactivated, the display is fine. Or if screen blanking is not engaged, close the lid, wait, and open it again.
