Default Rotation seems to freeze X

Hi guys,

I'm attempting to rotate one or both of my displays to be vertically-oriented, because I want more space for emacs editing. But when I try to rotate the display using either command-line xrandr or using nvidia-settings, the screen just goes black. It appears to do a mode switch or something, but then it never brings my desktop back up. So I'm not sure if this is an X crash or some other sort of failure.

I've got two Samsung 213T displays connected to a 6800GT and I'm using TwinView right now with each monitor set to 1600x1200 (screen #0 size is 3200x1200). I'm using 8762 driver release on 32-bit Ubuntu Dapper. My kernel is 2.6.15-25-686.

If this is at all useful, I will paste some of the potentially relevant portions from my xorg.conf file.

Code:
Section "Device"
        Identifier      "NVIDIA Corporation NVIDIA Default Card"
        Driver          "nvidia"
#       BusID           "PCI:1:0:0"
        Option          "RenderAccel" "true"
        Option          "AllowGLXWithComposite" "true"
EndSection

Section "Monitor"
        Identifier      "SyncMaster"
        Option          "DPMS"
        HorizSync       30-81
        VertRefresh     56-75
EndSection

Section "Screen"
        Identifier      "Default Screen"
        Device          "NVIDIA Corporation NVIDIA Default Card"
        Monitor         "SyncMaster"
        DefaultDepth    24
        Option          "TwinView"
        Option          "SecondMonitorHorizSync"   "30-81"
        Option          "SecondMonitorVertRefresh" "56-75"
        Option          "TwinViewOrientation"      "LeftOf"
        Option          "MetaModes"                "1600x1200,1600x1200"
        Option          "RandRRotation"            "true"
        Option          "NoLogo"                   "true"
        Option          "RenderAccel"              "true"
        SubSection "Display"
                Depth           1
                Modes           "1600x1200" "1280x1024" "1024x768" "800x600" "640x480"
        EndSubSection
        SubSection "Display"
                Depth           4
                Modes           "1600x1200" "1280x1024" "1024x768" "800x600" "640x480"
        EndSubSection
        SubSection "Display"
                Depth           8
                Modes           "1600x1200" "1280x1024" "1024x768" "800x600" "640x480"
        EndSubSection
        SubSection "Display"
                Depth           15
                Modes           "1600x1200" "1280x1024" "1024x768" "800x600" "640x480"
        EndSubSection
        SubSection "Display"
                Depth           16
                Modes           "1600x1200" "1280x1024" "1024x768" "800x600" "640x480"
        EndSubSection
        SubSection "Display"
                Depth           24
                Modes           "1600x1200" "1280x1024" "1024x768" "800x600" "640x480"
        EndSubSection
EndSection

Section "Extensions"
        Option "Composite" "true"
EndSection

Section "DRI"
        Mode    0666
EndSection
If there is any more information that I can possibly provide, please let me know.

Default Re: Rotation seems to freeze X

Please generate and post an nvidia-bug-report.log immediately after reproducing this problem. Also, what is the xrandr command that you're using to perform the rotation?

Thanks,
Lonni

Also, how should I generate the bug report after my X freezes or crashes?

Nevermind, I can ssh in remotely. I'll post a bug report log soon.

Default Re: Rotation seems to freeze X

So, I ssh'd in from another machine, then I ran (from the host machine) "xrandr -o right" and the screen blanked out as expected, and the terminal that I got from the remote machine froze up. So, it seems perhaps that it's crashing the kernel. I don't know enough of how I can debug this, so any suggestions would be appreciated.

You can generate the bug report before starting X again, after a crash.

Thanks,

Okay, so it's 116.3kb in size so it exceeded the 100kb limit of an attachment. I'm going to post it on my web shell instead.

http://www.gnome.org/~bratsche/nvidia-bug-report.log

Let me know if there's anything else I can do or give you to be of help.

Thanks

Default Re: Rotation seems to freeze X

I have a few questions:
0) Does this still crash if you're not using the Composite extension?
1) Have you verified that you're using the latest BIOS for your motherboard?

BTW, in the future, you can zip up the bug report to attach it here.

Thanks,
Lonni

0) I removed the "AllowGLXWithComposite" and "Composite" and the problem persisted.
1) No, not yet. I'll look into that.

Thanks!
