    Dell 1905fp acting weird

    Got a Dell machine with a X300 graphics card, and a 1905fp with a digital connection. When Kubuntu starts up, the monitor will just sorta blink on and off, on for 2 seconds maybe, then off for 1. It seems like it's some sort of issue with the refresh rate or something. I also have a CRT monitor, and using that things work fine. Also when I boot into XP with the 1905fp, everything works fine as well.

    If it ends up working (i.e. this only happens before the X server starts), it's probably just the monitor changing resolutions or refresh rates one or more times. Nothing to be worried about.

      i wish

      no, it keeps on doing it, and after that until the monitor is completely turned off and back on before a reboot it'll even do it while the BIOS and stuff is loading in the beginning. It really seems like kubuntu screws with the refresh rate on it and it doesn't go away until the monitor is turned off and back on.

        Hmm... Very strange. I'd say there's a problem with the monitor or cable, but if it doesn't happen with Windows...

        Could you please attach (or pastebin, or whatever) /etc/X11/xorg.conf?

            first of all, i actually did a reinstall, because i had messed around with it so much i just wanted to make sure i hadn't really screwed something up. Of course upon reinstall the graphics worked fine. Then i tried to go to the fglrx driver and that's when things got screwed up. The reason I'd been messing with it was to get compiz fusion workin. So now when i switch between the proprietary and open source driver it goes from not working to working. So it seems to be something about the proprietary ati driver in combination with my 1905fp. Here's my xorg.conf, and the flatpanel is currently working. When I change to the other device in the bottom section, that's when stuff breaks.

              Re: Dell 1905fp acting weird

              alright, i got it. The monitor gets screwed up at any resolution over 1152x864. In order to get it to work with 1280x1024 I had to add the following:
              HorizSync 64
              VertRefresh 60

              which are values taken directly from dell's support site.

                Yep, that's one of the suggested fixes.

                Glad to be of service... even though I didn't really do anything for you.

                EDIT: That table seems to be especially suited to be made into a modeline... How interesting.
