So I decided to upgrade from Fedora 19 to Fedora 20, so far the only problem seems to be related to my video drivers (everything else works exactly as before), I had to uninstall my beta drivers under windows to make the random black screening go away (fun!) and for the icing on the cake I had to ram my head against the MvM server because now it doesn’t seem to startup in quickplay mode anymore despite having all of the convars correctly placed.
I was all for the new update in the beginning, but this is turning into a royal pain in the ass. I wish Valve could put some straight forward guidelines on how to get setup, and what you can and can’t use in quickplay. The current list they provide leaves too many questions unanswered.
