I am running Doom3 on Linux. Everything worked out fine, as described in this documentation but I ran into a fix when I changed my screen resolution.
Now the games starts in a bigger window, the bottom part of which is inaccessible as it extends beyond my laptop screen size. The mouse pointer moves only inside this window, so neither can use the Doom UI nor can I move this Doom window to make the UI visible.
Is there a config file somewhere where I can specify the screen resolution, or some command-line parameters with which to start Doom3 ?
