I had the same problem on the same laptop model (HP G62). To bypass this issue, I disabled radeon at system startup by editing /etc/default/grub and setting the variable GRUB_CMDLINE_LINUX_DEFAULT in this way: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash radeon.modeset=0"
I hope this can be useful for someone else. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/766292 Title: 11.04 b2 (not start) -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
