http://ubuntuforums.org – Hi, My Os = Ubuntu 9.10. I'm using Samsung 14" (SyncMaster 551s) monitor. Screen Resolution: 1024 x 768 (4:3) Refresh Rate : 60 Some time the monitor Blackout before/after the Login Screen Display. But the Cpu/Machine is still running !! Then after approximately 1 minute it come back in work automatically. I've tryed with other Resolution like, 800 x 600 (4:3) But the problem is still there. And i didn't face this in older Ubuntus. What to do now ? Thanks! (Hardware)
