[SOLVED] Anybody know a good place to ask about this backtrace on X...

trist007 · 09-20-2012, 11:26 AM

I'm running Slackware 13.37 32 bit with Firefox 4. Everytime I click on Ajax stuff firefox freezes and X spikes to 100% and dumps this backtrace in the /var/log/Xorg.0.log. I'm just trying to get an idea of what might be causing the segfault. So far I'm thinking about either updating libpixman or trying another nvidia driver.

Code:

I'm using NVIDIA-Linux-x86-173.14.35-pkg1.run as the nvidia driver. I tried the newer 304.43 but it doesn't support Option "Rotate" "CCW" which I need. I'm going to try the older one 96.43.23 in a bit.

Well it was the old nvidia driver. So I installed the newest one NVIDIA-Linux-x86-304.43.run but I remember the last time I used it I couldn't get one of my monitors to rotate. So I looked further in and noticed that the "Rotate" "CCW" was deprecated. Here's how it should be implemented now.

Code:

Section "Screen"

# Removed Option "metamodes" "nvidia-auto-select +0+0"
# Removed Option "metamodes" "DFP: nvidia-auto-select +0+0"
    Identifier     "Screen2"
    Device         "Device2"
    Monitor        "Monitor2"
    DefaultDepth    24
    Option         "Stereo" "0"
    Option         "metamodes" "DFP: nvidia-auto-select {Rotation=left} +0+0; DFP: nvidia-auto-select +0+0"
    SubSection     "Display"
        Depth       24
    EndSubSection
EndSection
