Just saw a changelog go through which probably explains this: ----- gnome-power-manager-2.29.91-2.fc13 (FEDORA-2010-4350) Update Information: This update re-enables brightness changing support through HAL for some graphic cards. * Thu Mar 11 2010 Bastien Nocera <bnocera@xxxxxxxxxx> 2.29.91-2 - Update to 2.29.91 - Revert HAL removal, or some machines wouldn't have brightness handling any more ----- so yeah, it was a g-p-m change, update your g-p-m and it should work again. -- Adam Williamson Fedora QA Community Monkey IRC: adamw | Fedora Talk: adamwill AT fedoraproject DOT org http://www.happyassassin.net -- test mailing list test@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe: https://admin.fedoraproject.org/mailman/listinfo/test
