--- Comment #4 from cactipus mitch9654@gmail.com --- I changed my graphics driver from `nouveau` to `nvidia`, then changed back. Upon starting the game, I no longer get the "X error of failed request". The game actually starts - resolution changes, an instance of the game appears in GNOME's "alt-tab" list. However, I'm still looking at my GNOME desktop - the game doesn't actually appear.
At any rate, I'm no longer dealing with this bug, and I can't even reproduce it myself. It exists, but it's a little sneaky.
NOTE: I mentioned in the bug description that I tested with one monitor. I actually have three, but I just went into my display settings and disabled everything except the one. Perhaps that had something to do with it?
