schaij: It did not fix the issue. The same issue occurs again with the ScreenSelector.so not loaded.

Tuxgamer42: But you did install:

sudo apt-get install libgtk2.0-0:i386 libglib2.0-0:i386 libgdk-pixbuf2.0-0:i386

as suggested by jatowar? Your issue is definitely not related to corrupted Save Games; The ldd-command must not return any "not found " for ScreenSelector.so to load.

What does ldd $(find . -name "ScreenSelector.so") print now?

jasbisch: Hey there!

Just yesterday I bought the game and downloaded the recent version (1.11) 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
chmod: changing permissions of 'Truberbrook.x86': Operation not permitted
ERROR: ld.so: object 'libgtk3-nocsd.so.0' from LD_PRELOAD cannot be preloaded (cannot open shared object file): ignored.

Logging to /home/jasper/.config/unity3d/BTF/Truberbrook/Player.log"

The Player.log file contains the following:

"Desktop is 1600 x 900 @ 60 Hz
Unable to find a supported OpenGL core profile
Failed to create valid graphics context: please ensure you meet the minimum requirements
E.g. OpenGL core profile 3.2 or later for OpenGL Core renderer
Vulkan detection: 0
No supported renderers found, exiting

(Filename: Line: 560)"

I already installed OpenGL ("OpenGL version string: 3.0 Mesa 18.2.2") but I still get the same error.

Does anyone know, what I could do?

I'm really looking forward to dive into the world of Trüberbrook! =)

Best
Jasper
