2nd monitor doesn't work

[severe vale]

my laptop is the dell latitude e6520, with 3 USB ports and 1 audio port, one VGA port, one HDMI port, when I connect my tv to my laptop through the HDMI port, nothing shows, when I go into the display settings, it's just my main screen, any way to fix this?

[tidal anchor]

in terminal type mok-util --sb-state and share the output

[severe vale]

that's it?

really?

damn I didn't know Linux was this good

[tidal anchor]

No

[severe vale]

oh

ohhh

ok brb

dude

am I supposed to put the space in there?

because it's not working rn

command 'mok-util' not found

did you mean:
command 'mokutil' from deb mokutil (0.6.0-2)
Try: sudo apt install <deb name>

@tidal anchor

ok I tried it again without the - between mok and util and it said this: 'EFI variables are not supported on this system'

[tidal anchor]

well, that shouldn't be an issue then. inxi -Gxxx and show output

i don't have the tv connected through hdmi rn

[tidal anchor]

connect it and run again

[severe vale]

ok

here you go

anything?

[red edge]

have you tried a different port on the tv and verified that the tvs input is set to the correct HDMI port?

beyond that I have seen threads where people were unable to get secondary monitors connected to the nvidia card (as is the case in some laptops) working via nouveau

that said due to the age of the machine proprietary drivers may be a nonstarter

Looks like 390 is the most recent version nvidia driver that is supported

one might wonder if 390 via the graphics drivers ppa would work https://launchpad.net/~graphics-drivers/+archive/ubuntu/ppa?field.series_filter=noble be sure to understand how to switch back via the cli in case it doesn't work correctly

[weak elm]

From the inxi output, your HDMI port can only be accessed through the nvidia chip. And your nvidia chip is way out of support for the official driver, 390 was the last version with support. You can still install 390 on Mint 20.3, which is at the tail end of support (until April 2025), or use the free and open nouveau driver, which might not support this.
The easy solution is disabling the nvidia in BIOS and trying to run everything off the well-supported Intel iGPU. Or you start the painful path of getting nvidia to work.

[severe vale]

can't I install it on mint 22?

btw if I install the nouveau driver is it more up-to-date and will I get (possibly) more performance?

[weak elm]

We tried this with the last two users coming through here with that issue. It does not work, we have no solution.

[weak elm]

Look at the inxi output. You are running the nouveau driver. It is the default now, but it is basically a few hobbyists tinkering away without any help from nvidia, and it has numerous issues.

[severe vale]

ok

little off-topic but fps has been getting a little lower recently, like 45 fps, on windows I used to get stable 60

and yes I ticked use dedicated GPU if available on properties

[weak elm]

That is because nouveau is slow. You will get comparable performance if you get the nvidia driver to work, but as I said, this requires dropping back to an old Mint version (20.3) or finding a way to run it on something newer.

[severe vale]

wow ok

well thank you curunir and micheal

[weak elm]

The problem here is that nvidia cannot be arsed to support the chip any more, and they also do not support open source developers. All other GPUs are supported indefinitely, but the nvidia ones are left to rot.

[severe vale]

nvidia's just kinda lazy, huh?

[weak elm]

Look at how Jensen is behaving, and how they are pricing things. Gamers have given them a monopoly, and AI has made sure they cannot be punished for anything.

[severe vale]

ok

I gtg

cya later

[weak elm]

You can solve this easily by getting an AMD or Intel GPU, but on a laptop, you are stuck. You can use the iGPU, it is not all that bad.

[severe vale]

it's an intel hd-3000
