Linux Mint Launcher not working

[GCharb]

Hello everyone!

I just installed the 3D Coat 2021 trial in Linux Mint, the program works fine if I click the icon in the installation folder, I created a launcher, it appears in the Graphics categories no problem, but I just can't make it work, nothing happens if I click the launcher !

Here is the launcher code, any suggestions?

[Desktop Entry]
Name=3D Coat
Icon=/opt/3DCoat/data/Icon/3DCoat.png
Exec=/opt/3DCoat/3dcoat
Type=Application
Categories=Graphics;
Comment=Easy to learn 3D software for the creation of 3D models
Keywords=sculpting;modelling;texturing;rendering;

Thanks for any help, Gilles

it is complicated!!!

i assume you have not an nvidia optimus configuration on your pc.

then do this:

1) extract the 3dcoat package to for example /opt/3dcoat (as a normal user, this is a little bit complicated, but you can extract with a build in unpack manager and move the extracted folder within the command line with cp -R command (lookup how to use it))

2) make sure you are the owner of the folder, in command line:

sudo chown username /opt/3dcoat

sudo chgrp username /opt/3dcoat (username is your user, lookup how to use it)

3) i think you will need to set the environment variable, so that there is no startup error (which you will see when you start in terminal)

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/opt/3DCoat/LinuxLibs

For this you will need a shell script (mine is named s3dcoat.sh) which extends this variable and starts 3dcoat:

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/opt/3DCoat/LinuxLibs

__NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia /opt/3DCoat/3dcoat

(I have nvidia optimus, so I need these temporary variables:  _

__NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia

you can skip them, but /opt/3DCoat/3dcoat is important, because it starts 3dcoat.

4) you can than use the shell script in the .desktop file, which should be located in /usr/share/applications. My looks like this:

[Desktop Entry]
Name=3dCoat
Exec=/opt/3DCoat/s3dcoat.sh %U
Icon=/opt/3DCoat/data/Icon/3DCoat.png
Terminal=false
Type=Application
StartupNotify=true
Categories=Graphics;
Comment=Sculpt and paint program
Keywords=3d;paint;sculpt;retopo

 

Hope this helps a bit.

you can make it even easier. Install winehq and you can run the windows version in linux. performance is great.
