Upgrading from xf86-video-nouveau-1.0.10-3 to xf86-video-nouveau-1.0.11-1 causes X to crash when calling xrandr. I use xrandr to setup two monitors, so it makes the newest version of xf86-video-nouveau unusable for me.

This is an example of what causes xrandr to crash:

$ xrandr --output LVDS-1 --auto --primary --rotate left

I have attached the Xorg.0.log files from running X with xf86-video-nouveau-1.0.10-3 and xf86-video-nouveau-1.0.11-1. Everything pretty much looks the same. No big differences.

I have also attached the output of `startx`. Despite xf86-video-nouveau-1.0.10-3 being the one that works with xrandr, it looks like it spits out a stack trace when exiting from X and going back to the console. (This, of course, causes no problems to me as a user because I've already exited X.)

If you look in the file startx-output-xf86-video-nouveau-1.0.11-1, you can see the following suspicious lines:

resize called 1920 1920
/usr/bin/Xorg.bin: symbol lookup error: /usr/lib/xorg/modules/drivers/ undefined symbol: exaGetPixmapDriverPrivate

I bet the "resize called" line is produced when calling `xrandr`, and then the following line is what actually causes X to crash.

After googling around for the cause, I only really found the following page:

Here is the output of `lscpi -v` for my card:

On the Arch Linux News page for the xorg-server 1.6 update, it says that glamor accelerated rendering has been deprecated and the glamor package removed, but one of the comments on the ubuntu launchpad page mentions glamor, so I'm wondering if that is where the problem lies.

You completely misread that news item. The glamor-egl package was deprecated because glamor is now built into the server.

You're right!

Is there anything I can do to try to figure out why xrandr is not working? I'm not too familiar with how to go about debugging problems with X.

Feel free to report this upstream if something went broken.
