Hey guys, having some pretty big issues. I am using the FGLRX driver on debian testing (currently jessie). First off the data, hardinfo: http://jsbin.com/xezolalisi/1/ Player.log: https://www.refheap.com/99623 KSP.log: https://www.refheap.com/99624 Part of /var/log/messages: Apr 14 20:03:03 mordocai-pc org.gnome.zeitgeist.Engine[1215]: ** (zeitgeist-datahub:1538): WARNING **: zeitgeist-datahub.vala:226: Unable to get name "org.gnome.zeitgeist.datahub" on the bus!

That particular time it froze during the main menu! Even Alt+SysRq+K wasn't bringing any functionality back, I had to use the reset button. I have installed microsoft fonts, am using the launch options 'LD_LIBRARY_PATH="/usr/lib:$LD_LIBRARY_PATH" LC_ALL=C %command%_64', and have done echo "0099e747: 00" | xxd -r - KSP.x86_64;echo "0099e74c: 00" | xxd -r - KSP.x86_64. Any ideas? Edit: Changed launch options to simply '%command%_64' and left all graphics settings default besides turning off anti-aliasing and I got through the flight tutorial. Tried again with a bigger resolution and it crashed in the menu. Going to see how stable it is with no graphic changes. Edit2: Good news everyone! Like many before me, I have found that kerbal loves radeon drivers and hates fglrx! With the radeon drivers I can play with 1920x1080 highest texture detail with AA and edge highlighting full screen with no issues besides the known rotating FPS issue. If anyone else is like me and on debian jessie has found the need to switch between drivers these scripts may be helpful: switch_to_fglrx: https://www.refheap.com/99625 switch_to_radeon: https://www.refheap.com/99626 Note that in the above scripts the commented out line is no longer needed due to the discovery that update-alternatives takes care of that file. In addition, note that the fglrx kernel module will still be running when running radeon but it doesn't appear to cause issues. If it bothers you, write a modprobe.d to blacklist fglrx and move it into/out of the correct directory in the scripts.
