Cannot upgrade to Ubuntu 20.04 LTS

[Remy Dubertrand]

Hello,

I am new in the forum. I have a recent laptop and would like to upgrade my Ubuntu (with Xfce desktop) towards 20.04 LTS. I currently have problems with OpenGt and/or the driver of my video card, from what I can understand from the developers of a Mathematica-l software.

Thanks.
