      Hi @Subhajig ,
      What Ubuntu version do you have?
      Do you have an Nvidia GPU? You can check it with the following command in the terminal:

      lspci | grep VGA

        Thanks for quick reply,
        My UBUNTU version is 16.04.4 LTS.
        After giving "1spci | grep VGA" i'm getting following
        "00:02.0 VGA compatible controller: Intel Corporation Xeon E3-1200 v3/4th Gen Core Processor Integrated Graphics Controller (rev 06)"
        Thanks in advance.

          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
