  1. Updating an old laptop a coworker gave me. 9.04 to 9.10 update went to blank screen. I googled “Kubuntu 9.10 blank display”. 3rd entry was to this page and the exact fix. Thanks.

  2. ahhhhh…. thanks ever so much! This has been such a LONG and frustrating journey. I wish I could have found your site sooner!

  3. I just updated to Intrepid a few days ago and had been downloading a bunch of video conversion and editing programs when this happened to me. Startup, but just a blank screen, no login. Ubuntu forums were no help, but a bit of Googling uncovered this post. IT WORKED – Thanks so much. In fact, I’m posting this from my laptop right now. Much appreciated.

  4. This did not work for me!

    I selected Recovery Mode but was unable to log in as root! After selecting recovery mode, these messages was displayed on the screen:

    Gave up waiting for root device. Common problems:
    – Boot args (Cat /proc/cmdline)
    – check rootdelay= (did the system wait long enough)
    – check root=(did the system wait for the right device)
    -Missing modules (Cat /proc/modules; lo /dev)

    ALERT! /dev/disk/by-uuid8874485b-afa6-4ec7-bfef-b45b0d8c6dad does not exist. Droppingto a shell!

    Busy Box v1.13.3 (Ubuntu 1:1.13.3-1Ubuntu7) built-in shell (ash)
    Enter ‘help’ for a list of built-in commands.

  5. It works, but just for the session. When I quit and reboot, I get the black screen again.
    Any tip?
    Thans, Alph

  6. Wow, l have tried many websites to solve this. This appears to have rid my blank screen on startup. Cheers.
