I managed to mostly solve the problem; on page 5 of the link paxman1 posted (http://kubuntuforums.net/forums/index.php?topic=3098015.60) someone named ilowman suggested going to System Settings-Advanced-Service Manager and turning off Detecting RANDR (monitor) changes The effect was immediate; my screen now flickers only when loading KDE4.1, and when opening System Settings-Display. This seems to solve the glitches where the screen briefly redraws in a shifted position from normal; the people at that link seemed to think there are two kinds of graphical glitches going on here. One downside, however, is that while I can still switch screen resolutions to 1024x768 (and possibly others) I cannot switch back; I lost my first draft of this comment when X restarted instead. -- [Intrepid] Screen flicker/resync on X4500HD https://bugs.launchpad.net/bugs/275152 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

My laptop has this problem (filed duplicate bug report by accident). It's an Inspiron 6000 running Ubuntu Intrepid 32bit; Intel 915 Graphics, and the thing flickers every 5 to 7 seconds, as pointed out here. I had this thing connected to a projector earlier today (no problems with detection; it automatically resized the displays to 1024x768 and so on) and the flicker manifested as the overhead projector losing the laptop's signal every seven seconds or so. As far as I can recall the laptop screen itself was absolutely stable while this was going on; the NO SIGNAL ON RGB 1 just kept popping up every seven seconds, for one second. Unlike the OP, I ONLY see this problem while running X. The display is perfectly solid all the way through the BIOS to the Kubuntu setup screens, to KDM itself where the problem begins. On shutdown, the display is stable as far as I can tell; shutdown is fast and requires a few mode changes of its own. -- [Intrepid] Screen flicker/resync on X4500HD https://bugs.launchpad.net/bugs/275152 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Also happens for me, Dell D630 laptop (64 bit) with Intel GMA 965. I just upgraded from Kubuntu Hardy to Intrepid so I've no idea if this is KDE4 related. It looks like DPMS is kicking in briefly. The laptop's screen stays on while this happens. I made it stable by using xrandr to a lower resolution and then xrandr back to the native VGA resolution (1920x1200 in my case). ** Attachment added: Xorg.0.log.gz http://launchpadlibrarian.net/18495166/Xorg.0.log.gz -- [Intrepid] Screen flicker/resync on X4500HD https://bugs.launchpad.net/bugs/275152 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
