Comment 11 for bug 280798

I'm not sure if I should, but I'm moving this to Confirmed, as I have the same problem myself. I'm running up-to-date Jaunty.

Just as the original poster mentioned, xrandr works correctly, but the applet only offers “normal” and “upside down” as options.

My card is an nVidia 9600 GT, running the nvidia binary drivers (180). I have enabled rotation in xorg.conf with « Option "RandRRotation" "True" » (not sure if this is true for the original report).

A few more details:
* The display properties applet complains that “It appears that your graphics driver does not support the necessary extensions to use this tool”, and it asks if I want to use the “vendor's tool” (nvidia-settings). The latter works correctly, but is a bit too verbose for everyday use (I rotate my screen often). Also, it's a bit annoying that I get asked the same question every single time.
* For some reason the applet displays “Unknown” as the screen identifier. I imagine that's somehow nVidia's fault, but it's still annoying: I have a single screen, its name is manually entered in xorg.conf, and nvidia-settings is able to show it (also, if I ask it to acquire EDID info, it succeeds, and the screen's name is contained therein).

Let me know if I can provide any more useful information.
