I am running Linux Mint 14 (Nadia), using the Mate Desktop. I know that KSP is not officially supported on my platform, but since Mint 14 is basically Ubuntu, it should be able to make it work. Version 0.19.1 ran fine (after tweaking the start command to LC_ALL=C ./KSP.x86 or LC_ALL=C ./KSP.x86_64) KSP starts up fine and I can get through the menu to create a new game. After naming it and selecting a flag it starts to show the nice new loading animation and then just closes. It also closes in the same way when entering the settings menu. I tried running both, the 32 and 64 bit version, both with the LC_ALL=C... commands and without (only ./KSP.x86). The result is the same for all my tries. The console output is the same for all as well: Set current directory to /home/user/bin/KSP_linux-0.20.0 Found path: /home/user/bin/KSP_linux-0.20.0/KSP.x86 Mono path[0] = '/home/user/bin/KSP_linux-0.20.0/KSP_Data/Managed' Mono path[1] = '/home/user/bin/KSP_linux-0.20.0/KSP_Data/Mono' Mono config path = '/home/user/bin/KSP_linux-0.20.0/KSP_Data/Mono/etc' /dev/input/js0: driver version: 2.1.0 (20100) /dev/input/js0: fd 3, buttons 12, axes 6, name Logitech Logitech Dual Action /dev/input/js0: axis 0: raw 0, mapped 0.000000 /dev/input/js0: axis 1: raw 337, mapped 0.000000 /dev/input/js0: axis 2: raw 337, mapped 0.000000 /dev/input/js0: axis 3: raw 337, mapped 0.000000 /dev/input/js0: axis 4: raw 0, mapped 0.000000 /dev/input/js0: axis 5: raw 0, mapped 0.000000 Aborted I have an Radeon 4870 HD graphics card and as I said before, 0.19.1 ran fine in both, 32 and 54 bit flavors. Does anyone have an idea how to solve this?
