Comment 13 for bug 137307

Then I understand that either

a) something else pulled Xgl in when upgrading.
b) it was previously installed and only exhibited the problem after the upgrade.

On second thinking, a) cannot be since removing Xgl didn't pull out anything else due to dependencies.

In truth, I don't remember explicitly installing Xgl but I couldn't rule it out either. Is there some way to inspect the lifetime of a package in the system? First install, reason, things like that (note that I have already removed it)? My machine started with Dapper.

As a side note, if b) is what happened, should someone be notified about it? Is it normal that Xgl has no effect in feisty and cripples X in gutsy for this card?
