Random reboot of desktop

[MintingMint]

hi,

I happened twice today,

I was just browsing internet in firefox and youtube in chrome, nothing hard, the desktop suddently locked itself like after a long time inactivity, and asked me for the root password. then I'm back to the desktop but all my browsers are closed, the first time this happened I had unsaved text in the text editor and I lost it.

What do you think is going on ?

Hello MintingMint welcome to the Forum.
Please share your system info by going to:
Menu/System Reports/System Information/click "Copy"
and pasting it here.
(You can use the command inxi -Fxxxmprz on the Terminal.)

What do you think is going on ?

It sounds to me like xserver is crashing. If you want to kill xserver on purpose type
<Ctrl><Alt><Backspace>

That is not something you normally want to do, and it is very rare for it to happen without you pressing <Ctrl><Alt><Backspace>. It has never happened on my system.

it happened again right now, even if I restored an old timeshift backup (updated ofcourse).
here is the output of inxi -Fxxxmprz

The latest change I did in this computer is adding a graphics card (RTX 2080). I keps the opensource driver because I don't need GPU power on mint (I use it on windows 10)

Any idea ?

When did this start? How long were you using mint before this problem started? Do you leave the system up all the time or only when needed? I started having this same issue a few weeks back after updating, and I see another post having similar issues from last month.

[MintingMint]

I think the problem was using non nvidia drivers for my RTX, once installed, the problem where solved.
but this is a problem, I did not wanted to use proprietary software on my linux .
