Still a problem people... I did not have this problem from Dapper through Maverick, but since updating Maverick through Natty, Oneric, and Precise, to Quantal in one day this week, this bug has now affected me - I don't know which release intorduced it, but my guess is that Oneric or Precise were the culprit since I took a break after the Precise install and the problem appeared, so I upgraded to Quantal to see if that solved the problem but it did not.
The only software changes to the workstation have been the upgrades the OS imposed and the retirements the OS imposed. I have made no BIOS setting changes to this workstation since I built this workstation in 2008 and installed Hardy on it. The workstation has an American Megatrends BIOS v0804 on the ASUStek Rampage II Extreme mobo, a 2.93GHz Core i7, 12GB RAM, 6x250GB RAID (2 hot spare), and dual ATI Radeon HD 4850 graphics cards. 10 minutes after boot, WHETHER I'M ACTIVELY USING THE SYSTEM OR NOT; whether I'm logged in or not, both of my dual monitors shutdown and the only way to get them back on is to reboot the machine, then I have 10 minutes of "use" before my workstation is pretty much worthless again. 'xset [-display 0:0.0] dpms force on' does not turn the monitors back on. 'xset s reset' has no effect because apparently this isn't a screensaver issue. I have 2 ATI Radeon HD 4850 (RV770) cards in this workstation, but I'm only using 2 monitors now, not 4, so only 1 card is being used. I do not have gnome-screensaver installed it doesn't matter if I have xscreensaver installed or not - problem occurs regardless it doesn't matter if I forced off dpms (xset -dpms) it doesn't matter if I forced off screensaver settings (xset -display 0:0.0 s 0 0 ) if dpms is on, and the monitor has shut down, ssh'ing in xset -q tells me the monitor is on, but it's not... it doesn't matter what video driver I used (Ubuntu's default, fglrx, or the proprietary ATI drivers) it doesn't matter if I'm using cinnamon, gnome, or unity it doesn't matter if my power settings are set to not sleep or suspend It doesn't matter that my brightness settings are set to NOT turn off the monitor In case you think the monitors themselves are shutting down on their own, they're not. They are HP LP2465s and they are connected to two different workstations - two dual monitor setups, and the other workstation, when selected, has the monitors active and they work just fine. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/30969 Title: monitor suspends regardless of gnome-power-manager timeouts To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-power-manager/+bug/30969/+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
