      It seems that your system does not have a dedicated GPU. You should be able to run SAMSON with Intel (with built-in graphics), but you may lack some SAMSON features, which relies on GPU.

      Could you, please, check the result of the following command in your terminal:

      glxinfo | grep OpenGL

      If you see "The program 'glxinfo' is currently not installed", you will need to install the mesa:

      sudo apt-get install build-essential mesa-utils libgl1-mesa-dev

      After the installation, try the glxinfo | grep OpenGL command again in the terminal.

              Could you please run the following command in the terminal and post it here:

              locate libOpenGL.so

              If you see in the result, for example, /usr/lib/x86_64-linux-gnu/libOpenGL.so but no libOpenGL.so.0, you will need to create a symlink.

                  Does the command locate libOpenGL.so show you libOpenGL.so or not?
                  The symlink can be created in the terminal as follows:

                  ln -s target linkname

                      Could you, please, double-check whether libgl1-mesa-dev is installed:

                      sudo apt-get install build-essential mesa-utils libgl1-mesa-dev

                      Please, check the troubleshooting section of the SAMSON Installation guide.
                      You can do a symlink to the libQt5OpenGL.so shipped together with SAMSON:

                      ln -s $HOME/NANO-D/SAMSON/0.7.0/Binaries/SAMSONQtLibs/libQt5OpenGL.so $HOME/NANO-D/SAMSON/0.7.0/Binaries/SAMSONQtLibs/libOpenGL.so.0

                      or you can install compiz and create symlink to its OpenGL:

                      sudo apt-get install compiz-dev
sudo ln -s /usr/lib/x86_64-linux-gnu/compiz/libopengl.so $HOME/NANO-D/SAMSON/0.7.0/Binaries/SAMSONQtLibs/libOpenGL.so.0
