When I try to load Psychonauts it crashes and this is the result I get when running from teminal. Any help or suggestions are greatly appreciated.

  • What graphics card and which driver? Jun 2, 2012 at 15:09
  • What version of the game are you using? A new one was uploaded a few hours ago.

Psychonauts can definitely run on Intel Cards under Linux, you just have to force the card to allow s3tc textures. To do this under the command line, you would use:

force_s3tc_enable=true ./Psychonauts

And it should work. You might want to edit the .desktop file that the installer created so that it will point to a psychonauts.sh file that contains this command. That way you could still run the game from the app menu.

My .sh file looks like this:

cd /home/mike/Custom/psychonauts
force_s3tc_enable=true ./Psychonauts

And in the .desktop file I changed the exec from "/home/mike/Custom/psychonauts/Psychonauts" to sh /home/mike/Custom/psychonauts/psychonauts.sh

The sh command is absolutely necessary here, or else the game won't load properly and your desktop might lock up.

A word of warning: while the game will run on an integrated Intel graphics card, it probably won't run very WELL. You can adjust graphics settings in-game to try and improve performance, but it'll still be at least a little choppy.

  • It works, but it crashes on some cutscenes...

  • Works very well thank you. Will the same trick work for Amnesia? The game will load up until it asks for a name and then crashes.

    BrianXP7: I've found the Linux port of Psychonauts to be kind of unstable and a bit weak in the performance area as well. That's just the unfortunate nature of the port - it was not done all that well. The Windows version under Wine might perform far better. @shaneo I have not tested Amnesia myself yet. But I can confirm that it fixes the black screen problem in Bastion. Jun 3, 2012 at 23:05

It is likely that your graphics card is not good enough to play this game, as indicated by this error:

ERROR: Missing required OpenGL extensions: - GL_EXT_texture_compression_s3tc

It's also possible that you neglected to install proprietary drivers for your card, if it is Nvidia or ATI.
