I am having the same error, and I didn't remove nvidia-glx (which I believe is supported by ubuntu) but I did remove the compiz repos from sources.list
I ran "sudo aptitude update" as well as "sudo aptitude dist-upgrade" it didn't look like it removed any files (I had already removed my xgl/compiz and later my xgl/beryl before trying to get edgy.
I have attatched my sources.list as well as so you may confirm this, as well as my apt, and main logs in a tar file.
From my results thusfar I can derive that I successfully undid everything that was changed. However, please see my attatched log files, and tell me what I have done incorrectly, or, if this is truly a problem with Ubuntu, then consider this my bug report.
