If you have trouble installing SAMSON and cannot find an answer below, please check the SAMSON Connect Forum.

I have a high DPI monitor and icons in SAMSON look small#


  • Right click on the SAMSON executable program to open its properties and go to the "Compatibility" tab:

Properties: Compatibility

  • Click on "Change high DPI settings" and check the lower check box ("Override high DPI scaling behavior") and for the "Scaling performed by" select "System" from the list:

Properties: Scaling override

  • Restart SAMSON if it was launched.

Full Disk Access In MacOS#

It might be necessary to provide a full disk access on macOS for SAMSON, e.g., to be able to access ~/Documents, desktop files, etc. Please check an example of the procedure to add full disk access here: Please note that you will need to perform this for SAMSON and you will need to use sh instead of bash.


Cannot launch SAMSON on Linux due to missing xcb#

On Ubuntu-like Linux, you might first need to install the following libraries: libxcb-xinerama0, libxcb-cursor0:

sudo apt install libxcb-xinerama0, libxcb-cursor0

On CentOS-like Linux, you might first need to install xcb-util* packages:

sudo dnf install xcb-util*

Installing OpenGL drivers on Linux#

Please, check how to install GPU driver and OpenGL library for your platform.

Below are suggestion for Debian-based systems (e.g. Ubuntu).

First, to check which GPU you have run the following command in the terminal:

lspci | grep VGA

If you have NVIDIA or AMD graphics card, you can install their proprietary drivers. Please, check how to do it for you platform and your GPU.

If you have only an integrated GPU (Graphics Processing Unit), you may see only something like:

00:02.0 VGA compatible controller: Intel Corporation ... process Graphics Controller

In this case you might need to install Mesa.

First check whether you have Mesa with OpenGL already installed in your system:

glxinfo | grep OpenGL

To install Mesa execute the following command in the terminal:

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

Running SAMSON on Linux with an AMD GPU#

SAMSON requires a graphics card supporting OpenGL 3.2. To detect which GPU you have you may run several commands:

sudo lshw -c video
lspci -nn | grep VGA

SAMSON depends on and (to be precise, and, which are not provided by SAMSON and should be installed on your system. To check whether these libraries are installed on your system, you may run the following commands:

sudo updatedb

If you have no library in your system, you can make links to either the shipped with SAMSON, or to your system library, e.g. by compiz:

ln -s $HOME/OneAngstrom/SAMSON-Application/6.0.0/Binaries/SAMSONQtLibs/ $HOME/OneAngstrom/SAMSON-Application/6.0.0/Binaries/SAMSONQtLibs/


sudo ln -s /usr/lib/x86_64-linux-gnu/compiz/ /usr/lib/x86_64-linux-gnu/

In the first case, you will need to create this link every time your SAMSON has been updated. If you have no library, you may create a link to, e.g. depending on where you have

sudo ln -s /usr/lib/x86_64-linux-gnu/ /usr/lib/x86_64-linux-gnu/


sudo ln -s /usr/lib/x86_64-linux-gnu/mesa/ /usr/lib/x86_64-linux-gnu/

Otherwise, these libraries can be installed through a GPU driver or mesa. If, for example, you have Ubuntu 14.04 (up to Xorg 1.16) you may install the fglrx driver (please refer to

For a newer version of Ubuntu, if you have a recent AMD GPU, you may install the AMDGPU Driver or the AMDGPU-PRO Driver. Alternatively, you may install mesa:

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