Confirmed: libXext 1.3.3 solve the error spamming problem. You can install this version from Ubuntu 15.04 (Vivid) both i386 and amd64 (just in case).
NOTE: For steam users, you will also have to replace the steam libXext libraries provided by steam package. These libraries are, in your steam installation directory, here: - ubuntu12_32/steam-runtime/i386/usr/lib/i386-linux-gnu/libXext.so.6.4.0 - ubuntu12_32/steam-runtime/amd64/usr/lib/x86_64-linux-gnu/libXext.so.6.4.0 As log as you replace the "libXext.so.6.4.0" you wont have to replace the "libXext.so.6", as this one is a symlink to "libXext.so.6.4.0". -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1369113 Title: Steam game began crashing 2014-09-12 (cross-post Source bugtracker) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/steam/+bug/1369113/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
