Since Ubuntu team is just able to tell us to report that it doesn't work at each single version of the kernel, waiting for upstream to fix the trouble, I put here a workaround (tested on raring) to all those people whose got this 100% reproducible trouble since quantal release.
Add 'nomodeset' in GRUB2's kernel command line (using GRUB_CMDLINE_LINUX in /etc/default/grub) and run 'sudo update-grub2' Put lightdm_delay init script in /etc/init.d/lightdm_delay sudo chmod 755 /etc/init.d/lightdm_delay sudo update-rc.d lightdm_delay defaults sudo reboot Basically this script just reload radeon module and start lightdm daemon 1 second after. ** Attachment added: "lightdm_delay" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1029790/+attachment/3680718/+files/lightdm_delay -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1029790 Title: 1002:714a Can't boot without nomodeset option-kernel 3.5.X.X/3.6.X.X ATI M52 [Mobility Radeon X1300] To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1029790/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
