I got freeze at KSP startup when using Ubuntu 16.04 Mesa 11.2. It was early in the loading phase. There were 35(!) threads in total, most waiting in futexes & mutexes, but some were still active. Game just didn't progress forward. Using Git version of Mesa the game worked without freezes many times, until one time it again froze. When it starts OK, there are some rendering issues. E.g. when selecting settings, none of the setting tabs has any visible content. In the game itself: - "Choose flag" and Runway dialogs contents are also empty - Lines shown on hangar floor are flickering and their texture is garbage The game log file: ~/.config/unity3d/Squad/Kerbal\ Space\ Program/Player.log Doesn't show any warnings from Mesa. So yes, KSP 1.1 doesn't seem to work very well. As to your KSP 1.2-pre version... Do the KSP settings tabs look OK for you? When the game freezes, if you do "strace -f -p PID" (e.g. as root through SSH console), is the game still active? If you attach to it with Gdb, where it's stuck: $ gdb /proc/$(pidof KSP.x86)/exe $(pidof KSP.x86) (gdb) info threads (gdb) bt ?</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
