Hybrid graphics laptop (NVIDIA + Intel) - dual monitor setup (internal + HDMI) - second monitor not detected

[kamarada]

Hi, everyone! I know that people ask questions like this here and there, but it’s happening to me as well and I’m not sure my problem is the same as theirs.

I’m not sure how/when it started, but it’s been a few weeks since my second monitor is not detected by Manjaro. If I reboot my laptop into Windows, my second monitor shows image and works as expected, so I know it’s not a fault on my monitor or the HDMI cable.

I’m using Manjaro with the GNOME 49 desktop, latest updates applied, 6.12 (LTS) kernel.

Not sure this is related, but once I tried to make Optimus Manager work, without success, I just gave up on it.

I tried to install and use Optimus Manager because my laptop battery drains fast: I can use it for barely 2 hours without plugging it into AC power. Any help with that would be appreciated as well.

My gaming laptop is Lenovo Legion with i7-13650 and Nvidia 5070.

When you are using Nvidia Intel combo - use the combo driver

sudo mhwd -i pci video-hybrid-intel-nvidia-prime

Then use the envycontrol package to switch between gpu

sudo pacman -Syu envycontrol

Setting to hybrid mode

sudo envycontrol -s hybrid

Note: remember housekeeping, in context it is removing experimental packages - one benefit is that an update doesn’t need to pull several gigabyte data.

@kamarada

That could be anything - the battery is slightly worn

@kamarada

Battery:
  ID-1: BAT1 charge: 75.5 Wh (100%) condition: 75.6/90.1 Wh (83.9%)

• perhaps you are running the Nvidia GPU for everything
• perhaps the power profile is set to performance

[Zauberer-Merlin]

No direct solution, but some ideas …

My main system (where I am currently working on) is an Alienware Area 51m, that has a NVIDIA 2070 and an Intel GPU, Notebook Monitor+HDMI+display port monitor attached.

I did remove optimus etc., as this was not working on my system as well.
Yes, also here, 2,5-3h work without power attached is the maximum.

Would suggest you remove it as well completely, just to make sure that optimus is not hindering the GPU in any way.

I do not have “modesetting” installed - only video-nvidia.
Maybe this uses more power, probably this is true. But the system works.

I am on kernel 6.19 atm - 6.18 works great as well.
Probably you try 6.18 as well.

You are using the 590 nvidia driver as I do.

Probably you should try to use the 570 driver (or 575) as some people (also mentioned on the nvidia forum) do have difficulties with the 590 driver.

If I would be you, I would

• clean the system driver wise as much as possible, means
• remove everything that is not mandatory e.g. optimus, modesetting etc.,
• install 570 nvidia driver with the 6.18 kernel

It is not difficult

• in a terminal “sudo pacman -Syu”
• Install kernel 6.18 with the manjaro settings manager in your DE
• reboot
• do not log into any DE (or - if autologin is enabled: logout), and
• in a TTY
• with mhwd - remove the installed drivers completely, do NOT reboot, install only the needed drivers (e.g. 570), again … with mhwd
• reboot.

Hi @kamarada ,

I’ve posted one my own too: ISSUE: DisplayPort Alt Mode (DP-1) not detected after kernel update - #3 by rommond

For me, the solution has been install and change to 6.1.163-1-MANJARO kernel

Hope it helps.

@linux-aarhus

When you are using Nvidia Intel combo - use the combo driver

sudo mhwd -i pci video-hybrid-intel-nvidia-prime

Warning: a version of config 'video-hybrid-intel-nvidia-prime' is already installed!
Use -f/--force to force installation...

@linux-aarhus

Then use the envycontrol package to switch between gpu

sudo pacman -Syu envycontrol

Alright, installed!

@linux-aarhus

Setting to hybrid mode

sudo envycontrol -s hybrid

[kamarada]

My second monitor is back!

I forgot to tell, but I also removed Optimus Manager:

$ pamac remove optimus-manager-qt optimus-manager-git

@Zauberer-Merlin

Probably you try 6.18 as well.

My second monitor came back with 6.12, but I upgraded to 6.18 to keep things up to date. Then, I removed 6.12 to keep the system clean.

@Zauberer-Merlin

You are using the 590 nvidia driver as I do.

Probably you should try to use the 570 driver (or 575) as some people (also mentioned on the nvidia forum) do have difficulties with the 590 driver.

The ArchWiki says the appropriate driver for my card (GPU family = Ada Lovelace) is the nvidia-open package, which is currently version 590. Since other measures were enough to solve the problem, I’m not going to try this, but thank you for the suggestion.

I’ll try to measure the battery comsumption now and share some statistics here. Thanks everyone!
