Hello,
I followed @omano guide to install nvidia 340 driver with 5.10 lts kernel.

No my pc is functional (Thanks Omano). The only thing is, I lost multi gestures (it was working before). Is not as important as the use of a second monitor (now I can) but it could be nice to have it. Do you now what could I do?.
Thanks for your help,
AO.
