F13, KDE. I have the screensaver set to activate after 5 minutes and it seems to work fine. Nevertheless if I leave the machine for a long period, say an hour or two (I'd need to experiment more to be sure, and that takes time of course) the monitor refuses to wake up but just shows a small error message of its own telling me that the recommended settings are 1440x900. Needless to say, that's the resolution I already use. The monitor is a Samsung SyncMaster 920NW, landscape format LCD, and it worked fine in F12, F11 and I think F10 (I've had it for a while). The only recourse seems to be a hard reset as there's no reaction to the keyboard or mouse. I haven't yet tried ssh from another machine to poke around. If anyone tells me what to look for I'll be happy to do it next time. I turned off power management to see what happens. It didn't make any difference. poc -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
