Package: supertuxkart Version: 0.9-4 Since Supertuxkart 0.9 we use xrandr instead of vidmode for changing resolutions.
The main issue is that if someone will force to use xinerama in his system, then xrandr extension will be totally disabled. Unfortunately STK 0.9 has a bug and in this case it thinks that whole desktop resolution is (0, 0). And it will cause a crash. I already fixed it just after 0.9 release: https://github.com/supertuxkart/stk-code/commit/f019f8622c93e57c12c0763dba44416c580f85a7 We had one bug report about it where someone confirmed that this commit fixed this issue: https://github.com/supertuxkart/stk-code/issues/2165#issuecomment-98944452 I would suggest to apply this patch, at least in Debian testing. It will allow to run STK in windowed mode when xrandr is not available.
