[Gate-users] problem with /vis/open OGL

[Sarah Blind]

Dear Gate users, 

I'm new to Gate and I encounter the following problem while executing a very simple code: 
when I write 



/vis/open OGL 



in my main.mac I get the following error message: 


BQ_BEGIN

"OGLSQt" is not compatible with your chosen session, and no fallback system found 

BQ_END


Yet OpenGL is installed. Has someone an idea what the problem can be? 

I'm working on a virtualbox with Ubuntu 20.04.3 LTS. 
I installed Gate 9.1 throught the ubuntu software center. 

Many thanks for your help, 
Sarah
