Not sure why I can't find similar bug reports. Don't know why this is not working just for me.

I can't build any rockets because I can't connect parts together. The windows does not have such effects.
If I move (for example) a separator under the command part it won't snap together.

I am using the Steam version under Ubuntu 12.10 (64 Bit).

Hello, I can confirm this.
After I saw the Linux version coming out I decided to instantly buy the game after I tried the Demo on Steam and got the same problem.
The green balls indication where to connect parts are not on the parts, they are like 5x the parts size away from it, making it impossible to connect any parts.
The game is unplayable this way, can't produce an aircraft.
Loading pre-saved aircraft won't work, too (e. g. "Kerbal X"). They don't show up. When you go to the Launch after selecting one of these ships you end up in space (you should be at the ramp though) not able to fire any stages and not seeing your ship.

System: Ubuntu 12.04 (64 Bit)
Graphics: ATI HD5570 (drivers working fine)
Processor: Intel I3

Can you guys both make sure you're using the correct Locale settings? Bug #427 seems to describe the issue you're having.

#4 Updated by r2p2 about 7 years ago

You are right. After starting steam with LANG=C steam I am able to load predefined crafts and create my own ones. It seams that it is a not so obvious duplicate.

I'm french an I have the exact same issue (Steam, Ubuntu 12.10 64bits, belgian-french locale).
Changing the launch command of steam by "LANG=C optirun command" worked for me (optirun is there because I have Nvidia Optimus technology).

Thank you for sorting it out !

Got the same Bug... It was with the Ubuntu Versions 12.10 and 13.04, 64Bit

But LANG=C didn't helped...

#8 Updated by Stechi almost 7 years ago

Also the same bug with Ubunt 12.10 x64,
LANG=C didn't fix the bug,
also I played default with english localization,
so the error shouldn't occur in the first place.

Kerbal v0.20.2.0 on Steam

The same here in Fedora 18 x86_64, I can't connect any parts and I don't even see the green dots for doing it.

#10 Updated by LamerTex almost 7 years ago


Here the same problem in Ubuntu 13.04 x64 with nvidia 670 and Intel i5.

The only way to play the game is to launch it from the directory with "LC_ALL=C ./KSP.x86_64" command.

With this it's working fine, only the audio is completly wrong (see the image below).

Why after 4 months this bug is always here?

How can I start the game from steam without every time have to start it from the terminal?

#11 Updated by KingCrunch over 6 years ago

Still exists. LC_ALL=C works for now

#12 Updated by jw almost 6 years ago

Still experiencing this issue on Ubuntu 14.04, locale nl-be (Dutch, Belgium), with the latest version of the demo on Steam.

Also, this thing is really un-Googleable.

@LamerTex, to start from Steam, change the "Launch options" in Steam to:

LC_ALL=C %command%

or, for the 64-bit version:

LC_ALL=C %command%_64


#13 Updated by TruePikachu almost 6 years ago

The demo is an older version of the game (0.18.3) then what the issue refers to (0.19.1).

#14 Updated by sal_vager over 4 years ago

  • Status changed from Confirmed to Resolved
  • % Done changed from 10 to 100

This was caused by KSP using the systems locale to set the float delimiter, this is no longer the case in the current version (1.0.5)
