--- Comment #37 from Phil Armstrong <[email protected]> 2011-11-29 09:15:44 PST --- OK, to update this bug, with kernel 3.1.1 (Debian current release) I used the command "sleep 10; xset force dpms off" to trigger dpms. In single user mode, just udevd, Xorg, portmap and an xterm running: The guilty setting on my monitor appears to be "Auto Switch Input". With this on, X is unable to put the monitor to sleep at all; the screen goes black but the monitor remains on. With Auto-switch input off, dpms works fine. With a Gnome desktop booted: With auto-switch on, I get the same behaviour as reported for single-user mode. With it off, I sometimes get the previously reported "sleep, then wake-up" behaviour, sometimes not. Killing upowerd doesn't make any difference. Presumably something else is waking the monitor up, but I can't work out what's making the difference: perhaps there's some internal monitor or graphics card state? Meanwhile Windows is able to put the monitor to sleep permanently regardless of monitor settings on the same machine. So this bug is still extant as far as I'm concerned. -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. _______________________________________________ xorg-driver-ati mailing list [email protected] http://lists.x.org/mailman/listinfo/xorg-driver-ati
