Thanks for debugging this. I'm also adding xorg to this bugreport since it appears something in X is intercepting the keyevent and blanking the screen. Could you do the following:
Paste in output of: lspci -nn | grep VGA Attach /var/log/Xorg.0.log To triagers/developers: 1) xev is showing the key press event for XF86Suspend. 2) with no GPM running, the screen is turned off on keypress 3) on key press with GPM running, GPM does not tell screen is turned off, but it turns off anyways ** Package changed: gnome-power-manager (Ubuntu) => xorg (Ubuntu) ** Changed in: xorg (Ubuntu) Importance: Undecided => Low ** Changed in: xorg (Ubuntu) Status: New => Confirmed -- Pressing Suspend key turns off display instead of suspending https://bugs.launchpad.net/bugs/410829 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in ubuntu. _______________________________________________ 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
