External screen not detected.

---

Hi.

I’m running Antergos on a laptop with an external screen. For the first day, there was no issue with the screen.
The next day, though, merely trying to boot with the screen connected or plug it in made Antergos freeze.

From the third day on, the screen is just never detected anymore.

My laptop is a Lenovo Thinkpad P71, the external screen is connected in HDMI.

lspci -v returns this concerning the driver in use:

01:00.0 3D controller: NVIDIA Corporation GP104GLM [Quadro P3000 Mobile] (rev a1)
Subsystem: Lenovo GP104GLM [Quadro P3000 Mobile]

i would try to get proprietarynvidia driver running:

sudo pacman -S nvidia-installer
nvidia-installer -t if this do NOT give any error do a real install:

sudo nvidia-installer

install nvidia settings:
sudo pacman -S nvidia-settings

reboot and see if it works again!

Thanks for your answer. Unfortunately, it did not succeed.

nvidia-installer -t did give an error, so I tried installed nvidia-settings and rebooted, to no effect: screen still not detected, “nouveau” still listed as the driver.

So, I tried sudo nvidia-installer, but it tells me it can’t find a suitable driver for my graphics card!

This mean your card is not in the database, but you can force installation:

sudo nvidia-installer -f

That did the trick, thanks, man.

you are welcome!

@joekamprad Ok, it worked for a day, but next boot: the external screen is detected… but no longer the laptop screen itself.

nvidia-settings ?
DE settings?

Neither nvidia-settings nor the settings of the DE (Cinnamon) detect the laptop screen, only the external.

possible this is a hybrid graphics saystem with intel + nvidia graphics?

No, pretty sure there’s only the Nvidia card.

Here are the specs, it’s stock (outisde of the US, Antergos single boot): http://psref.lenovo.com/Detail/ThinkPad_P71?M=20HK0002**.
It’s a work laptop, paid by the employer, so I didn’t fiddle with the hardware at all.
