Fix access to the event* device associated with your joystick. > If your distro uses udev (Unified device control), which it probably does, you can fix this yourself. The rules used by udev to set up devices are in /etc/udev/rules.d You shouldn't change the rules files because any kernel upgrade might overwrite them, but you can add a custom file. The rule that's affecting you is: KERNEL=="mouse*|mice|event*", NAME="input/%k", MODE="0640" in '50-udev-default.rules'. These files are applied in lexical sort order at boot time, so you can add a file called, say, '55-my-custom.rules' to contain the following lines: # Custom rules # # Give user,group and world read and write access to /dev/input/event* # KERNEL=="event*", NAME="input/%k", MODE="0644" This rule will override the access permissions set in '50-udev-default.rules'. You'll need to do this as root. Use any text editor (vi, emacs or gedit will all be fine) to create the file, which must be: - owned by root - in the root group - read and write accessible to root - read accessible by group and world Check this once you've created it and use chown and/or chmod to fix ownership and access as necessary. If you try this be very careful not to change any of the existing files: you can upset the entire i/o system if you damage them. Make sure you keep a copy of your custom file somewhere safe. You may need it again. You'll almost certainly need to reinstall it if you do a clean install of a future Ubuntu release or change to a different distro. HTH Martin
