If you already have a running Calculate Linux system, simply update to CL 20.6.


thanks for update , since im newbie i will wait for update to drop on console

It would be interesting for you to do a GUI and a cli of the emerge to make things easier
But I don’t know if that would be against your purpose.

It’s planned, but later. Now the task is to rewrite the utilities to Python 3.

Would it also be possible to add hybrid graphics support in the system installation?
I don’t know how to get Nvidia’s hybrid drivers into the gentoo base

We don’t have laptops with hybrid graphics. It’s gonna be hard to test.

Even so I can test it
Just add that I test
