Nvidia Graphics card not detected... After disabling it..?

ua flag

I had installed the graphics card drivers and all when installing the OS. Everything was fine until my laptop started to switch off due to heating issues due to nvidia graphics card.... So I somehow disabled* it in a way i dont remember... Now lspci -k | grep -EA3 'VGA|3D|Display' returns

omsk@omsk-Latitude-E6420:~/Desktop$ lspci -k | grep -EA3 'VGA|3D|Display'
00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09)
    DeviceName:  Onboard IGD
    Subsystem: Dell 2nd Generation Core Processor Family Integrated Graphics Controller
    Kernel driver in use: i915

It is just not able to detect the card... N now I have fixed the heating issue so i want to re enable it..

I have a Dell Latitude e6420 having a nvidia nvs 4200m.

I m on ubuntu 20.04 LTS.

Thanks in advance.

It would be preferable if you remember what you did and where but here are some suggestions: First check UEFI in case that's where you somehow disable it. If not there then open Nvidia X Server Settings.

If it was me I'd look in command `history` for clues as to what I did (did you use commands?) or if you made package changes in apt logs (`/var/log/apt/history.log`) for details of what you did.. etc. Given you've not yet told us what OS & release you are using, we know almost nothing about what you did.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
