The Linux Thread!

Quick question before I spend a lot of time running through the script on page 1, is it still valid for Ubuntu 14.04?

[sal_vager]

Yes, the scripts should all be fine for all versions of Ubuntu, and indeed all Linux distro's, as a terminal of some sort and the shell that runs inside it are standard to all Unix-like operating systems.

Quick question before I spend a lot of time running through the script on page 1, is it still valid for Ubuntu 14.04?

If you refer to my script: Should work partial.

As I don't play KSP actively at the moment i only check this thread now and then for News.

My Script has Problem downloading the latest version from the Kerbalspaceprogram website, as a workaround download the zipfile manual and place it in the same directory as the script.

At all:

The problem:

There is maybe something broken with the SSL Certificate of the KSP Website.

If you download something via wget, it aborts and you get the following error message:

ERROR: cannot verify kerbalspaceprogram.com's certificate, issued by '/C=US/ST=Arizona/L=Scottsdale/O=GoDaddy.com, Inc./OU=http://certs.godaddy.com/repository//CN=Go Daddy Secure Certificate Authority - G2':
  Unable to locally verify the issuer's authority.
To connect to kerbalspaceprogram.com insecurely, use `--no-check-certificate'.

Has anybody a idea what this error really means or has a proper workaround (No diasableling '--no-check-certificate' is not a proper workaround).

Also thiy problem may be know: http://forum.kerbalspaceprogram.com/threads/117966-trouble-accessing-kerbalspaceprogram-com-on-Firefox

It's the site certificate, if you try opening the KSP website in a new browser it will complain about the certificate as well and there is nothing we can do about it.

It is Squads responsibility to keep their certificates up to date and to use reputable issuers instead of GoDaddy.

So while it is true that disabling '--no-check-certificate' is not desirable, it is the only workaround.

Hey guys,

Upgraded to Ubuntu 15.04 recently. Made sure I had the latest nVidia drivers. Installed KSP, and it runs fine absolutely stock. Yay!

Then I got crazy. Installed CKAN and downloaded some mods. But now KSP crashes after finishing loading all assets and switching between the loading and main menu screens.

Player.log is indicating a SIGSEGV, and at the end of the log is indicating that more than 16GB of memory is being used. However, the System Monitor doesn't indicate any usage above 6GB while KSP is running.

Logs on DropBox: https://www.dropbox.com/sh/q9c0mu16ieta8ix/AAAiecOmqDLOF9IoEcA0hfspa?dl=0

I'm at a loss as to how to fix it from here... Thanks in advance for any help you guys can offer!

Looks like it's trying to use a memory address outside of 16gigs, not that it's using 16gigs, so it'd be an invalid call rather than running out.

The stack trace actually specifically mentions a 2D texture call and clouds.

Stacktrace:

And the KSP.log also ends with clouds.

[LOG 13:35:33.217] Clouds: Cloud Material initialized

[LOG 13:35:33.217] Clouds: Generating Overlay...

So I'm guessing it's the clouds...

Hello there,

I'm comin back again with my Ubuntu 14.04LTS issues...

This time it's about the LC_ALL=C fix that seems to not work anymore.

I use to launch KSP with a little bash file in order to change the cwd to KSP's folder (for the atmospheric and reentry effects) and to set the LC_ALL env variable. Here is my script :

#!/bin/bash

cd "/media/Documents/Jeux/Steam-Linux/Kerbal Space Program"

LC_ALL=C ./KSP.x86_64

Since last sunday, the graphics settings are systematically reset after each KSP reboot (and the sent data confidentiality dialog too, off course) , as if the LC_ALL=C fix was not working anymore (I should remind that I'm using a french desktop).

This happened after an ubuntu update if I can remember (but I'm not 100% sure).

So if somedy has encountered the same problem and would share some advices, it will be greatly appreciated

And while i'm on that, are the __GL_THREADED_OPTIMIZATIONS=1 and LD_PRELOAD="libpthread.so.0 libGL.so.1" variable definition still necessary for KSP 1.0.4??

Thanks for all (welcome) help.

[Edited]

My OS is Ubuntu 14.04, GTX 760 with Nvidia drivers v355.11, libc is v2.19 (if that could help).

I'm getting consistent hangs/freezes at around T+32 on the basic flight training mission.

I've tried lowering all of my graphics settings as low as possible, but to no avail. Also tried updating drivers and ensured that I'm using the proprietary nvidia-304 driver. KSP.log has no hints and dmesg doesn't show anything interesting.

Any ideas?

[YellowApple]

Player.log is indicating a SIGSEGV, and at the end of the log is indicating that more than 16GB of memory is being used. However, the System Monitor doesn't indicate any usage above 6GB while KSP is running.

As far as I can tell, this is a Unity bug; other Unity games (like Cities: Skylines) have the same problem when running under 64-bit Linux. I've tried asking about this in Unity-land, but I haven't gotten anywhere. Best one can do is limit how many mods are installed while hoping that the problem doesn't exist in Unity 5.

[Stone Blue]

So I was perusing my Player.log for giggles, and I see the following at the top.

My question is mainly, why is my 2GB VRAM dedicated at the top, but anear the bottom, it shows 0 MB VRAM detected?...Also, it looks like KSP is defaulting to using OpenGL? is that correct?

Thanx for any insight... (Oh, this is Lubuntu 15.04, KSP 1.0.4 64bit)

I have a desktop system (Centos 7, x86_64, Core2Duo, 8Gb RAM, Nvidia, Nvidia proprietary driver), here KSP works fine.

But on my laptop ThinkPad x220t (Ubuntu 14.04 LTS, Core i5, 16GB RAM, intel graphics) it doesn't works The game running, display starting game menu, but when I try to load anything, for example, asteroid mission, I seen vessel, navbol, panel, and... black screen. No space around. I try googling, and read FAQ in start post of this thread, but it doesn't help me.

I use clean, 32 bit installation from Steam(in future I want to change it to x86_64, it works on my desktop fine).

How I can fix my problem?

Hi hargin, this sounds like the joystick bug, your gfx settings will reset if you start KSP with a controller bound but no controller present.

And __GL_THREADED_OPTIMIZATIONS was never necessary, it's just reported to help for some players (though I never saw a difference).

KSP on Linux and OSX uses OpenGL, this is normal, the VRAM thing is a Unity bug however and there's nothing we can do about it, thankfully it's completely harmless.

Thanks sal_vager, I've my answer. I saw that there was issues with joysticks.

I tried to test my joystick, but as the thrust axis has an assigned range of −32768 to 32767, only half of my axis is taken into account (KSP set the thrust only from 0% to 50% or from 50% to 100%).

So piloting aircrafts becomes a real challenges.

I didn't wait for your answer : I did a full KSP reinstall

Edited November 8, 2015 by hargn

[Zekario]

I'm running KSP on a Thinkpad X220 with Arch Linux. I have a few odd problems, here's a few:

When resuming after a suspend (systemctl suspend, or shutting the laptop lid) while having KSP started, the sound doesn't come back on. I have to fully restart KSP to fix it. This is pretty annoying, and I'd like to fix at least this.

Quicksaving doesn't show the "quicksaving..." in the corner.

I can't use aero-effects. Settings says it's hardware related, but I wouldn't be suprised if it wasn't.

CPU hovers in the upper 50%s, even when doing nothing and on the main menu screen.

I also had a few problems I fixed or I can't replicate, like black VAB fixed by turning a setting off, the Mun disappearing, buttons being blacn, etc.

I'm starting to think my thinkpad is faulty. I had none of these problems on my desktop and other (now dead) laptop. Edited November 24, 2015 by Zekario

[sal_vager]

Hi Zekario.

I don't know about the sound, maybe a pulseaudio issue?

Does quicksave work, have you tried rebinding it to another key?

KSP checks for anti-aliasing before enabling some effects, so try turning on anti-aliasing in the KSP settings screen.

¯\_(ツ)_/¯

The black VAB is caused by the PPFX edge highlighter with Intel drivers, this may also have made the Mun and buttons disappear.

[Zekario]

I use ALSA for sound, and the same thing happens when I suspend on my desktop. Possible KSP bug? I don't remember this happening on PulseAudio, maybe I'll try that.

Quicksave works. I can use F5 and Mod+F5, but the messages don't pop up.

No aero-effects is okay, I guess.

I can live with CPU usage, I don't do much else when playing KSP. And hey, unused CPU is wasted CPU (Right?). Only thing that may be a problem is heating.

Makes sense. I don't have those issues after disabling it.

ALSO: I can't see the fonts on menus like the debug menu. Do I need certain fonts for it to display properly?

Also: Thanks for helping everyone with their KSP troubles on Linux!

[ETPOF]

Hello. Hopefully I'm posting this in the right place.

I'm running Ubuntu 14.04 and earlier today my game crashed. I'm not sure why, but it has happened before and everything has turned out fine. The first time, Kerbal told me I had invalid/broken saves and I needed to either delete them or cancel. I canceled and replaced my persistent.sfs with my quicksave.sfs file and was able to play again. However, this time it asked me again and I clumsily clicked delete. Now my save is gone. Is is possible to recover it before I spend most of my time hyperediting everything back? If you need more information I can give you more. Any help is appreciated.

[sal_vager]

Zekario, KSP uses [U][URL="https://en.wikipedia.org/wiki/FMOD"]FMOD[/URL][/U] for sound via the [U][URL="http://unity3d.com/"]Unity3D[/URL][/U] game engine, and it looks like [U][URL="http://answers.unity3d.com/questions/524602/audiosource-glitching-when-resuming-from-suspend-o.html"]others have also had issues[/URL][/U] with sound after using suspend.

No idea on the quicksave message, maybe there's an error in the log to say why, you can open it in-game with rightshift+F2 or check your Player.log in ~/.config/unity3d/Squad/Kerbal\ Space\ Program/ , also you can enable anti-aliasing, "no hardware support" doesn't mean AA won't work.

KSP also uses a lot of cpu on my desktop, no idea why or if it can be reduced.

For fonts you will need Arial.ttf and ArialBd.ttf files in your usr/share/fonts folder, you can get these from the ttf-mscorefonts-installer package on Debian systems, there should be an equivalent on Arch, [U][URL="http://forum.kerbalspaceprogram.com/threads/92231-The-Linux-Thread!#linuxthread06b"]more info here.[/URL][/U]


ETPOF, not easily, KSP doesn't make a backup or send the folder to the recycle bin so your only choice is to try an undelete program and hope it recovers the files.

The Ubuntu repository contains a few programs to do this, they are extundelete, magicrescue and testdisk.

[Zekario]

I installed XFCE4 then uninstalled it, and that fixed lots of KSP related problems. I don't know either. Quicksave and debug fonts show up, and I think my only KSP problem now is the suspend-sound thing. My CPU makes more sense now, going up when actually doing things and going down when on menus. It even made CKAN work, before it have errors. I'm confused, but happy.

I have AA on, but aero effects still don't want to work. It's fine though.

Thanks for your help!

[fade2blk]

I've been trying to fix my performance issues with Linux KSP on and off for months now. This thread finally provided the answer.

I had massive FPS hits every time I panned the camera around or even moved the mouse too quickly. Turns out my mouse defaults and locks to a polling rate of 1000hz on Linux and changing the rate via usbhid does nothing. I grabbed a cheap mouse locked to 125hz and the FPS drops are finally gone.

[Ricardo.b]

LC_ALL=C is not working for me.
the game is in a different HD, but the terminal gives: Permission Denied

what do I do?

[sal_vager]

Well, LC_ALL=C should not be needed anymore, with 1.0.5 the game was made to ignore the users locale.

But if you're getting permission denied you'll need to check the permissions of the files, if you're dualbooting with Windows make sure Linux and KSP are on a Linux compatible file system (not NTFS or FAT).

What filesystem and mount options does that drive have? (see output of 'mount' command)

If it's NTFS, it's possible to make permissions play nice, but not straightforward, best put KSP on a Linux-native filesystem.

Check that your "different HD" isn't mounted with "noexec" - Ubuntu does this by default for some reason.

 

On another note, why the bleep do we have an "answer this question" button on this thread now? which question? What if it's an informational post - i.e. the top of this thread?

Well, this is a bother, when I'm logged in I cannot see the first post, so I can't edit it, instead all I see are the hidden old posts I used to use to arrange the thread.

When I log out I can see the first post just fine, and all the hidden posts are hidden but because I'm not logged in I can't edit it.

And I can't completely delete the hidden posts, because I want to use those to arrange the thread ...

[Torih]

Is it just me or is the link for the physics file missing? 

Need to grab a new one since I seem to be missing all reentry and aero effects for some reason.
