I installed steam-login from here and it worked just fine. Then I went back to Unity and it wouldn't load Unity anymore. When I tried running compiz from the Ctrl+Alt+F1 command line it gave me the output below.

When I googled the first error line, I found this page. It's in greek but it does mention xfwm4 which steam-login makes use of so I'm thinking that could be the culprit. Any suggestions on how to reset things? I tried this page, that didn't do it, as well as some of the commands in the other greek web page and that didn't work either.

Try resetting compiz by executing the command below:

rm -r ~/.config/compiz-1; rm -r ~/.compiz

Then give restart.

  • That fixed it. However there's still a bug in steam-login or one of the dependencies that it uses, because as soon as I log back in with steam-login, the behavior is exhibited again and I have to remove those folders to reset compiz again. I filed the issue here Sep 28, 2013 at 20:58

    I think this has something to do with your steam installation. If you downloaded steam.deb file from the web site, remove that and install steam from Ubuntu software center. If you installed Steam from Ubuntu software center, do the other way around. Reset Steam as well. rm -r ~/.steam

  • steam-launcher that was installed was from the beta. It got updated to the ubuntu repo version when it came out. I uninstalled and reinstalled steam from the software center but I'm not gonna rm -r right now since I'll have to reinstall all my games again. Oct 2, 2013 at 14:50

    It seems I didn't have to rm-r ~/.steam including all the folders pointed to in the symlinks. Just reinstalling the steam-launcher package with the one from the ubuntu software center and removing the steam folder only fixed it. It works fine now. Oct 2, 2013 at 19:41
  • However, this doesn't solve my problem. Tried a lot of ways.
