KSP 1.1.3 won't start anymore

[Martian Emigrant]

I have been running KSP on Linux for a few months now with the usual little nags.

1.1.3 and pre 1.2

Today I tried changing my Video card driver. My shadows have been messed up for a long time and I read about the Video card being to blame. With messages of failures on my attempts. Officially: No changes.

Now KSP will flash on and off when I try to run it.

So I think I did something the game doesn't like.

I am contemplating reinstalling Linux. Upgrading the version.

Before I do:

Could something else be going on?

I used to be a half decent administrator on Windows. Linux not so much.

I dread having to do the reinstall. It was a pain to do in the first place.

Could it be easier than that? Am I missing the obvious?

I just need a Yea or nae.

 

Thanks,

Certainly, but without logs, console output, system / OS details and more information on exactly what you changed... kinda hard to say what that might be.

From / to? Method?
Checked that OpenGL acceleration is actually working? ( output of glxinfo | egrep 'direct | vendor', test in other OpengGL apps etc. )

You never have to reinstall, but it may be easier. Largely depends on one's level of GNU/Linux package management foo and/or patience.
In theory, if you know what you changed, just put it back. Might be easier to say than to do though.

Apart from GPU drivers (this is the thing that changed, no?), there are also a few Unity bugs that can prevent the game starting, might be worth checking the known issues etc. in the linux thread.

What steve_v said. If you consider re-installing than that is probably the easiest way ...

Thanks guy.

I hate it. But I know I have to do a fresh install.

Getting a coffee then I will prepare a backup of my files.

Well, technically it is most surely not necessary. I deducted from your questions that you don't consider so much to track that error down.

I personally wouldn't install new, i'd take a look at the different logs to draw the circles ever more narrow and in the end i'd see where the error is. Or i'd or revert to the old driver if no error could be found or it would take too much time. But since we do not even know how you installed the new driver and you didn't care to tell us, a new install is probably the fastest and most frictionless procedure :-)
