** Description changed: The symptoms reported with https://bugs.launchpad.net/ubuntu/+source/linux/+bug/451282 persist. After resuming from sudpend the display returns fully dimmed, and display brightness can't be adjusted, neither using FN keys, nor using KDE power management control. The issue occurs regardless whether the supend state was activated by low battery, by closing the display, or by explicitly selecting sleep mode in KDE. Killing and restarting X does not solve the problem. A reboot does. Notebook: HP 8530w, Quadro FX 770M, Nouveau driver.
