    Display corruption when changine resolutions

    I wanted to post here first before filing a bug report, since I don't know if I could explain the bug correctly anyway.
    The OS drivers have always behaved this way for me, even the latest GIT (as of a week ago).
    Hardware is:
    Inspiron 1501 w/ Radeon Xpress 1150
    From what I understand it's an R300 core. Phoronix-test-suite system-info says:
    Code:
    Dell Inspiron 1501, Chipset: ATI RS480 + SB600, System Memory: 2386MB, Disk: 60GB TOSHIBA MK6037GS,
 Graphics: ATI RS482 [Radeon Xpress 200M] 128MB
    Well basically, 75% of the time the screen corrupts when switching resolutions (such as starting a game), I get a screen that looks like this:



    If I switch to a terminal by Ctrl+Alt+F1, then back to the previous screen with Ctrl+Alt+F7, the screen displays correctly. It seems that sometimes it doesn't "take" to the new resolution, and switching back and forth solves it. I'm wondering what steps I should take to find out exactly whats causing the problem? TIA.

    Fun. I don't know much about output configs and such, but for a bug report you should at least also provide?
    - Are you using KMS or not?
    - dmesg and Xorg.?.log

      The corruption looks awesome. I wonder how hard it would be to make a screensaver that looks like that, then maybe rotate around randomly.

        Thanks for the replies. Cool looking or not, it would be nicer to see the game i'm trying to play . I just remembered that one of the olllld versions of FGLRX would cause a screen like this during GDM loading, since it was trying to set a mode the LCD didn't support. The thing is that now, the modes ARE supported. They just don't... catch on the first try always.

        I just did a clean install of Karmic 9.10, but prior to this I was running the xorg-edgers ppa. I've experienced this behavior with all versions of the open source drivers. As far as I know KMS is enabled by default in the current Karmic kernel, but i'm not positive. I'll check into that.


        My xorg logs are almost half a megabyte in size... I trimmed it a bit, so hopefully it's still useful:

            The problem is generally that the xvidmode extension doesn't always work well with xrandr 1.2. xvidmode always assumes one crtc/output per screen, while with randr 1.2 you can have multiple crtcs and outputs per screen. So for backwards compat xvidmode uses the compat crtc and output which may not correspond to the actual current output topology. For example the compat crtc and output may be crtc 0 and VGA-0 while you may be using crtc 0 and LVDS. So when xvidmode is used, it screws up the output state. I think there are some fixes in xserver master.

              I spent a good deal of time reading the Radeon man-pages and trying out some options, but to no avail. AGPFastWrite and EnablePageFlip both cause X not to start for me, and nothing else I tried had any effect.

              I did some searching, but couldn't find any info on xvidmode. Are there any options to force modes that can be changed by an end user?

                There's an xrandr utility for querying and changing display modes. I don't feel confident saying that xrandr has replaced xvidmode but it seems that way to me.

                  Sorry to necropost, but i'm still experiencing this problem. I've tried using Xrandr to switch resolutions, but the results are identical.

                  On a depressing note, both Fedora 12 or Ubuntu Lucid alpha exhibit this same problem, except immediately after boot. I guess KMS triggers the corruption when it sets the resolution initially.

                  Anyone have any new ideas? I'm currently running Ubuntu Karmic. I could honestly make due with only the default panel resolution, but with most distros going to KMS, it looks like i'll soon be out of luck.TIA!

                    It's been a few more months, and no change for the better. I get the same result as my last post with the Lucid RC and Fedora 13.

                    I've been using Karmic for the last few months and just never changing the resolution, but now the display goes corrupt on bootup with lucid. It's definitely something to do with the laptop display panel not accepting the resolution or refresh rate it's being fed.
                    I can start up my computer now If I plug in an old CRT monitor i've got laying around, and then switch the laptop LCD on and off a few times. Then it'll eventually pop up with a good picture.

                    As said, i've always had this problem with the open source drivers. I think it's not necessarily related to the drivers themselves, but rather to randr. I honestly don't know, and i'm at the end of my rope as far as this laptop goes. Anyone have any suggestions?
