It does not start the MATE desktop environment

[Destac]

I have updated the system and when i restart the desktop does not load. It tries to access, but the black screen does not stop blinking and the low bar appears, it is like in a loop.

optimus-manager?

Yes, I have it installed because I use an Nvidia graphics card.

Users of optimus-manager, beware the python update!

There was a large amount of python updates. Now optimus-manager does not work. I got to the login screen and the monitor turned black, then flashed a bit with the cursor and then black to black and repeat. After arch-chroot and some thinking I removed Optimus-manager and now it works again. Just a heads up!

Thank you very much, I was able to solve the problem
