Thanks pmp6nl. I would just like to add that I'm now fully up and running with 11.04 64bit on my Toshiba laptop with its HD3400.
The trick was adding "nomodeset" on the grub boot line, which finally got me to the log in screen. Following that I have installed all recommended updates (inc a lot of xorg ones) and (taking a big risk) installed the proprietary FLGRX driver. Everything is fine. In post no 46 I may have selected nomodeset in the install as well, come to think about it. (I was trying lots of different combinations of settings at the time.) -- 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 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/763909/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
