Hello there, I just made the update to 11.04 and i have the same problem Here is a brief explanation of the steps that occur during the boot, as i noticed above these were not clearly mentioned ..
I have a dual boot setup alongside with windows 7 so at the dual boot screen, choosing ubuntu usually displayed a black screen with the boot options, which after the update is purple (and font size is smaller, not sure if that's also a bug or on purpose) After choosing the latest Generic, the boot will show up some boot text quickly and then get to the splash screen Immediately after the 4'th "dot" appears on the loading screen, my display would go to black, then turn on again, then back ... indefinitely In other words, the display dims over and over.... I did not reach the login screen yet and i have no option of stopping the loop other than Ctrl + Alt + Delete (Escape used to work before when i had a similar situation) In my next attempt, i tried going to the recovery mode to check for errors, did not get anything, and when i chose the resume option, i experience the same thing as above I am fairly new to ubuntu and i don't know what to do besides that.. If there is anything i can do to help, please let me know, i am usually online most of the day :) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/763909 Title: 11.04 Wont Boot With Mobility Radeon HD 3400 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
