[Not solved] No External Display on Lenovo Legion 5 15ARH05H

Hello Garuda users.

After a fresh install of Garuda Dragonized Gaming, I have lost the ability to use external monitors on my laptop (Legion 5, 4800H, 1660ti)
I have confirmed it works on POP!_OS.

The Nvidia dGPU seems to work fine besides the monitor issue;

prime-run glxgears

works properly and shows in nvtop

Here is the output of my garuda-inxi:

I apologize for the loss of indentation.

P.S. I can't promise instant responses, but I will attempt to respond asap

I'd recommend you switch to discrete graphics in the UEFI, then everything will "just work".

Thanks for the help but unfortunately, booting with Discrete Graphics enabled results in either freezing at the "LEGION" boot menu or booting into a black screen.

Unfortunately Legion laptops are notorious when it comes to their 'hybrid' mode. As far as I know, hybrid mode disables external monitor completely as the ports are connected to the gpu directly, so using external monitors is out of the question. And if that wasn't bad enough, latest nvidia drivers causes issues on dedicated gpu mode with a lot of users to the point where many of them had to rollback to previous drivers (have two friends who can confirm this).

The only thing I can suggest to you is to retry dedicated gpu option and to check if there are any bios updates on Lenovo's website. If you have to flash your bios, please be aware to be VERY CAREFUL WHEN FLASHING BIOS as it is a very delicate process and if anything goes wrong during the flashing process, it can brick your system entirely. Hopefully someone else here who have Legion laptops will have a better solution for you.

All the best.

I'll look into the bios, but I don't think the root problem is with my BIOS.

With the same settings, POP!_OS is able to drive the dGPU and monitors.

I'd prefer to fix my garuda install rather than go back to POP! if possible.

Thanks,

~Saik

You're right, this being a bios problem does seem silly, I was only going off based what my friends have reported and some news about legion laptops. I do hope you find a solution soon though, all the best. :slightly_smiling_face:

Well my new laptop arrives some time today, I'll probably give up on this endeavor and use this laptop as a server from my dorm room.

Make a Bios update. As i see your Bios version is very old and outdated (FSCN14WW date: 08/26/2020)
Bios your find here

How to make it without Windows ?
1.) Download Windows 10 PE Gandalf’s Windows 10PE x64 Redstone 7 Spring 2022 Edition
2.) Take some usb-stick install Ventoy on it. and put the iso on the stick and the dwnloaded fscn25ww.exe also on the stick.
3.) Boot Windows PE and after booting launch the exe
4.) After all is finished reboot and make your Bios settings as it was before. (TPM off, secure boot disabled etc....)

This suggests you have made other configuration changes, e.g. you ran nvidia-xconfig and have hard-coded the display settings.

Believe me - as someone who has a 17ACH6H - discrete graphics is the easiest way to get things working.

This sounds pretty interesting, given that Lenovo will only give me my drivers in .exe format. I'll have to give this a try. (P.S. I haven't touch the Legion laptop in days since I got a newer better laptop)
