Hey there!

I bought the game and downloaded the recent version (1.12) for Linux (Ubuntu 18.04 LTS). After installing the *.sh script (without problems), I'm unable to launch the game. Executing the start.sh script I get the following output:

"Running Trüberbrook

The Player.log file contains the following:

"Desktop is 1600 x 900 @ 60 Hz

I already installed OpenGL, this is what "glxinfo | grep OpenGL" tells me:
"OpenGL vendor string: Intel Open Source Technology Center

Even if it seems, as I have a core profile version of 4.5, I get the same error.
This is my system's technical specification:
"Memory: 4Gb

And a bit of more detail on the graphics (from the GOG.com System Report):
"Intel Corporation 4th Gen Core Processor Integrated Graphics Controller (rev 06)

Does anyone know, what I could do? Thank's so much in advance!
I'm really looking forward to dive into the world of Trüberbrook! =)

Hi Jasper,

I am not entirely sure if your graphics card supports opengl3.2 but there might be an issue with dependencies and lacking 32bit libraries. Since someone else faces the same issues as you I just copy my reply in here:

Then, check that you have all glx libraries as 32 bit versions, as well.
'ldconfig -p | grep GL'

You should get an output like this:
libQt5OpenGL.so.5 (libc6,x86-64) => /usr/lib64/libQt5OpenGL.so.5
libOpenGL.so.0 (libc6,x86-64) => /usr/lib64/libOpenGL.so.0
libOpenGL.so.0 (libc6) => /usr/lib/libOpenGL.so.0
libGLdispatch.so.0 (libc6,x86-64) => /usr/lib64/libGLdispatch.so.0
libGLdispatch.so.0 (libc6) => /usr/lib/libGLdispatch.so.0
libGLX_mesa.so.0 (libc6,x86-64) => /usr/lib64/libGLX_mesa.so.0
libGLX_mesa.so.0 (libc6) => /usr/lib/libGLX_mesa.so.0
libGLX_mesa.so (libc6,x86-64) => /usr/lib64/libGLX_mesa.so
libGLX_mesa.so (libc6) => /usr/lib/libGLX_mesa.so

Make sure you have the libc6 version (without the x86-64). If you are missing some, then install them. Since I am on opensuse I can't give you the exact command but it should be something like
'sudo apt-get install missinglibrary:i386'

Also make sure your graphic drivers are up-to-date and if you have a Nvidia card use the proprietary drivers (because nvidia doesn't love linux).

If it still fails I would suggest opening up a support ticket with GoG (which might be a good idea anyway).

However, if you are in the mood for a little bit of console magic you can also run the game with
'strace ./start.sh'

and if that gives to much output

'strace ./start.sh 2>&1 | grep GL'

Normally it should tell you which libraries are loaded and then you see where it fails.

Finally, you can also try to run it with wine if you can't solve the dependencies issues (even though thats not really the point of using linux ;-) ).

Hello Jasper, dmsoxid,

Just to add one thing: When I have re-installed Trüberbrook, there was (meanwhile) a new version available (1.13). I have used this one for re-installation. Do not know if solution would work with 1.12 as well. I think you should give 1.13 a try.

Best regards

Dear @dmsoxid,

thanks for your help! Now the game is running for me!
It helped a lot, that you gave me the explicit code for the package to install including the name for the library, as I would not have known how to find that one.

And thanks @olliprivat for your advise as well. Actually I have used v1.13 as well. So I cannot say if it works with v1.12 as well. But I think so, I guess at least my problem was the missing 32-bit library.

Thank you both! I'm off to Trüberbrook now!

Cheers
Jasper
