Mouse is too fast/sensitive in Defcon on Ubuntu 11.04/11.10
Posted: Wed Nov 23, 2011 8:28 pm
The mouse sensitivity in Defcon is extremely high, making it very difficult to click on buttons, etc. in game. Moving my finger 1/4 of the way across my touchpad moves the cursor across the entire screen. This is roughly 8x as sensitive as my touchpad outside the game. Is there any way to adjust the sensitivity?

I suspect this related to SDL.
I've done quick search, most posts refer to setting the environment variable "SDL_VIDEO_X11_MOUSEACCEL".
For X11, sets the mouse acceleration. The value should be a string on the form:
where n and d are the acceleration numerator/denumerators (so mouse movement is accelerated by n/d), and t is the threshold above which acceleration applies (counted as number of pixels the mouse moves at once).
The necessary environment variable is SDL_VIDEO_X11_MOUSEACCEL.
I found that setting SDL_VIDEO_X11_MOUSEACCEL didn't work for me without setting SDL_MOUSE_RELATIVE=0 too.
So, for example:
$ SDL_MOUSE_RELATIVE=0 SDL_VIDEO_X11_MOUSEACCEL=6/1/0 openttd
There are other reports which suggest that
Open a terminal and type
Add these lines
to the end of the file. Save and exit. Log out. Log back in.
The environment variables will be set for all programs you launch.
