Seems to be something wrong with the video "auto" setting in .supertux2/config
When I checked the older version of Supertux, the setting is video "sdl" You can check the video setting for Supertux2 from the terminal(CTRL+ALT+t) as in this example: $ grep 'video \"' .supertux2/config (video "auto") What fixed it for me - setting the video mode to "sdl" in the .supertux2/config file. 1.) Make a backup of your configuration file (optional): $ cp .supertux2/config .supertux2/config.bak 2.) Run this to update your Supertux2 config file to use "sdl" instead of "auto" or "opengl". $ sed -i 's/video\ "auto"/video\ "sdl"/g;s/video\ "opengl"/video\ "sdl"/g' .supertux2/config 3.) Below is example of expected change: $ grep 'video \"' .supertux2/config (video "sdl") The game runs good for me after this setting. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/320734 Title: game play is very slow in supertux2 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/supertux/+bug/320734/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
