The bug is still present in 12.04. The workaround of disabling GPU scaling through the nvidia-settings utility still works. But that still leaves the login screen with an incorrect resolution. Additionally guest sessions will always start with an incorrect setting, so after starting a guest session you have to start the nvidia settings utility, then disable GPU scaling, then manually set the correct resolution. That makes the workaround way too cumbersome to be acceptable, especially for the guest account which is expected to be used by less experienced users.

Ubuntu reports that the monitor is not detected and defaults to a screen resolution of 1280x800 pixels. When I use the monitor preferences to change the resolution to 1024x768 (which is the correct resolution for this projector), the image gets even more blurry than when the incorrect resolution is used. xdpyinfo claims the resolution has been changed to 1024x768 pixels, but the actual output being sent on the DVI port is still 1280x800 pixels. It appears Ubuntu has configured the graphics chip to scale the 1024x768 image to 1280x800 pixels which the projector then needs to scale back to 1024x768 pixels, which results in a blurry output, which is almost unreadable. The bug exists in both the preinstalled Ubuntu 9.04 as well as in the Ubuntu 10.04, that I just installed from the official Ubuntu DVD image.
