Bug Description

After an update (kernel?), I have begun to receive the message "Running in Low Graphics Mode" at boot. I can tell it to use Default setting from the options it offers, and get by it, after which things look and work normally until a reboot, which may or may not occur correctly.

If I select extra graphics debug messages and display boot messages in Xdiagnose, this problem DOES NOT occur. If I deselect those, the problem begins again.

I don't know which update caused it, but it was somewhere around mid or early May.
