Hi @Syutenjyo,

How did you install gw, was this a conda install?

Currently the conda binary doesn't work with wayland sessions, so perhaps this is the cause. You can check if you are running wayland by typing echo $XDG_SESSION_TYPE. If you are using wayland you will have to build from source, or install using linuxbrew.

I think the runtime dir can be set using:

export XDG_RUNTIME_DIR=/run/user/$(id -u)

To debug the graphics config issue, you can try running:

glxinfo | grep "OpenGL"

This will tell you if OpenGL is available. If OpenGL is not working you will need to install some libraries, these might help:

sudo yum groupinstall "Development Tools"
sudo yum install mesa-libGL mesa-libGL-devel
sudo yum install glx-utils
sudo yum install libXrandr-devel
sudo yum install libXinerama-devel
sudo yum install libXcursor-devel
sudo yum install libXi-devel 

Running gw in debug mode can also be helpful, if you share the output from GW_DEBUG=1 gw hg38. Thanks
