Thank you so much! Unfortunately, my KSP backup directories were all wiped out, so I'm kinda starting from zero.

Super kool, thanx dude.

@GreeningGalaxy Unfortunately, it seems like the server is wiped and the files don't appear to be available. Does anyone happen to have to zips?

I'm sorry, I'm a yutz, AMDGPU was installed the whole time, and I did know this, but I forgot. elfa ~ # apt install xserver-xorg-video-amdgpu xserver-xorg-video-amdgpu is already the newest version (1.1.99+git1608230731.73c8dc~gd~x). But now I'm wondering, could it be my motherboard? I'm using an Asus F1A55-M which has a built in video thing for AMD GPU on CPU that I'm not using. I know that if I cold boot my computer with the monitor off, I have to reboot because it wont enable the video card properly (bios not linux). I did buy a replacement, but stupid me bought the wrong board for the chip ordered at the same time.

Thanks @Kerbal101 and @LatiMacciato Actually, the glitch/update problem was experienced with the main branch drivers from Linux Mint and Xubuntu, on this card, HD6950, a HD4830, and one other that I can't remember, as well as with oibaf on two of those. KSP does the menu text thing, and a shadows sourcing from the wrong direction thing on main branch. Both of those are corrected with -force-glcore, but scatterer does a lines in the sky thing with it. Using oibaf, KSP's graphics works reasonably well, except when they become unstable, and then the GUI in VAB/SAB flickers. I'm almost completely convinced that firefox is causing the update issues. AMDGPU-Pro doesn't function on this card, and I have yet to try AMDGPU or AMDGPU+. KSP segfaults randomly, but is more stable on a fresh boot, and without firefox in the background. Once KSP segfaults once, it's my grandfather standing up to pee until a reboot. I'll try the stuff you'all suggested latter. Edit: Correction, I think on the HD4830, oibaf made everything screwy,

@Kerbal101 Tada...

@LatiMacciato Nope, you can't. If you don't load those plugins, you lose your window and control bars. Sad me. But, I guess I now know there's something wrong with the vid driver.

@LatiMacciato I didn't have it installed before, so I installed it. I really don't like the decoration/resize/etc tweaks. Will these workarounds work without those enabled?

I decided to post an example of the "after image" phenomenon I was talking about. I realize this isn't KSP specific, but, I can't find an explanation anywhere else, and it *does* affect KSP. And I hate the Ubuntu forums. This vid is like 8 seconds long, and just so happens to have Scott Manly in it. https://drive.google.com/open?id=0BwrwTiBuln0sTTJjQmZJaUw4ak0

@azander Do you think the flash plugin could be breaking the vid driver? Because there's a few things that make me think you might be right if you do.

I'm still experiencing random crashes as well on XFCE Ubuntu 16.04.1 LTS, however, I've also been noticing some odd behaviours. After a crash; then reboot, I can play for much longer, but that's usually a given. If I restart the game immediately, I get video glitches and texture errors such as the app menu listing mods beyond it's lower limit, or the "grass" texture looking stretched. These errors persist between restarts, and the game usually crashes in minutes. If I delete the whole ksp directory, and recopy from archive, I don't need to reboot, and the video issues don't come up as they would had I simply restarted, however, I cant really find caches in the ksp structure. Maybe ksp modifies its files? Maybe a temp somewhere else? Deleting Unity's pref file seems to help in my case as well. The oibaf driver repository has updated several time recently, but they haven't resulted in any stability changes for ksp. I still think Firefox and/or the flash plugin is contributing to instability somehow. Just to reiterate what I've tried: Changed vid cards, still ATI though Changed destros Minimalist install Updated vid driver Have not tired Catalyst/AMDGPU yet, kinda avoiding it right now, will be trying soon Scripts listed in this and the old thread And with Dev versions of several libraries

CPU and mem pass on both test, and don't cause instability in programs running in conjunction. However, I figured out that I was talking through my nose before. KSP still sigfaults even if nothing's loaded. It's utterly random, and I might again be deluding myself when I say that it seems a little more stable when launched from a terminal, and in windowed mode. And I was having so much fun when it worked for a day.

@LatiMacciato I agree it might be flash, but it's also happen with VirtualBox, however, with Vbox, it's hard for me to reproduce the error as the both combined, chew my system memory to shreds.

I think I might have figured out one of the contributing factors to my game's instability, but I didn't even know it was a possibility to be a cause. Although, I could be seeing pasterns that aren't there. It seems that when I have a particularly high load on one core, and not the others, say when Firefox is loaded and rendering something, KSP is more apt to segfult. I had thought asynchronise multi-threading would not lead to instability, but if unity is issuing FIFO free commands, it would explain a lot, and explain why this is only happening in the new multi-core optimized version. Then again, I could be talking out of nose, but, I was able to play 20 hour straight without interruption (crashing seems to make me aware of the time so I don't over play) without programs or daemons in the background. Again, no idea if this is correct, but as soon as I opened Firefox to listen to a thing, KSP crashed in 5 minutes, but when I tried again with nothing, I played for 6 hours more; then crashed again when I opened Firefox. It could be something to do with Firefox specifically, I don't have too many intensive programs to test with that wouldn't also grind the system to a halt. I also find that after a segfualt, I get... glitched. I get like an after image of what was in video memory before the crash, like the picture of KSP's loading screen. It doesn't LOOK like an after image mind you, it's the whole and complete screen. The effect has a name, but I can't remember it.

Oh, I have no doubt that it'll eventually be fixed, even if some bodger has to come up with some kind of patch or exception for linux. It's just a bummer that it's not now. Besides, I bought the game when it was 7 bux, so, I can't really complain.
