Problem still occures on Toshiba A300 with ATI Radeon 3470. (Ubuntu 12.04.2, gnome-shell).
Almost every time I was informed that watchdog detected hard lockup on cpu. (No log file to post at the moment) I've tried adding "nomodeset" to GRUB_CMDLINE_LINUX_DEFAULT, but with no luck. Also tried this solution: http://mylinuxexplore.blogspot.com/2011/11 /solved-ubuntu-doesnt-shutdown-properly.html, which didn't solve it either. No issue with open source drivers. WORKAROUND: For the last month I've been able to shutdown safely, killing Xorg first. sudo killall Xorg && sudo shutdown -P now -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to fglrx-installer in Ubuntu. https://bugs.launchpad.net/bugs/750437 Title: fglrx hard lockup on shutdown To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/fglrx-installer/+bug/750437/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
