I have somes problems with some games in Ubuntu 12.04 64 bit, both in WINE and with native games in that I can't control the characters since they always move forward or in circles.

That happens in Grand Theft Auto: San Andreas, but also in the native Linux games Psychonauts and Shank making the games unplayable (so it's not a problem with WINE, I guess).

Does anyone know what's happening?

Is there a possible fix?

Do you use a gamepad or keyboard / mouse ? –  mark kirby Aug 8 '12 at 9:59
    
I use both. I have a x360 controller that I use in some games, like super meat boy. but it happened before I hooked the controller. –  faceless Aug 8 '12 at 10:36
    
Ok. Found the source of the problem, the joystick input. Namely, the file /dev/input/js0 related to joysticks. I just renamed the file and everything went to normal. Is there a better workaround? how do I disable joystick input in Ubuntu? –  faceless Aug 8 '12 at 12:03

1 Answer 1

Use:

$ cat /sys/class/input/js0/device/name

or

$ jstest /dev/input/js0

to find out the name of the device that is causing the problem. It's probably the laptops accelerometer that you should be able to blacklist via /etc/modprobe.d/.

Found the source of the problem, my microsoft keyboard 600 is detected as a joystick. I guess that's a curse for using microsoft hardware in an open-source operating system :P. Still I would like to prevent this. Any ideias? –  faceless Aug 9 '12 at 3:21
