Wifi and Display issues with endeavouros on Zephyrus G14

General system Newbie
1

hey all,

i’ve been experimenting with dual booting on my GA402XV Zephyrus G14, however i’m running into problems pertaining to wireless connection speeds and some graphical glitches.

I followed the guide on https://asus-linux.org/guides/arch-guide/

i’ve tried endeavouros, a manual install of arch, and garuda linux but i’m having the same issues on all three so i’m guessing im doing something wrong or something isnt compatible with the g14 hardware?

[1] wifi speeds are incredibly slow compared to windows on the same laptop, i have been unsuccessful in figuring out why.

my wifi card is the mediatek MT9722

[2] Experiencing graphical glitches as well, in login screens and when booted into the desktop environment despite having all the nvidia drivers. When watching a video, playing a game, or moving windows around blocks of green/miscolored generic looking glitches flash and then disappear and repeat. it kinda looks like bad editing of glitch effects in a youtube video lol. it’s mostly just annoying visual flickering on some parts of the screen

(additionally fan speeds have been weird, but I’ve read multiple reports that that is apparently normal with this laptop and arch based distros? so idk)

Any help would be appreciated, and if I need to provide more information/screenshots just let me know.

The WiFi card should work on the latest kernel. What does it show

inxi -GNa

Edit:
Is it a Ryzen Cpu? Maybe post the whole hardware output. Post the url

inxi -Faz | eos-sendlog

yea it’s a ryzen cpu.

and also the wifi card does work; it just isnt as fast as it is on windows for some reason. At work i get like 4Mbps and at home i get like 40Mbps (taken from speedtest-cli) I have no idea why its so much slower at work even though my work laptop, which runs ubuntu, gets normal internet speeds and is typically pretty fast. but my personal laptop running eos gets like 4Mbps lol

honestly the wifi issue is lame but its bearable, what isn’t bearable is the screen glitches, which are present in the login screen always and then comes and goes when im using my laptop for unknown reasons.

edit: idk what i did but wifi speeds are normal and comparable to windows now so nevermind that

If you’re using Wayland, I suggest logging in using X11 instead and confirm whether the graphical issues persist.

I can see your BIOS is up-to-date, so we can rule that out at least :+1:

Hey bink, thanks for the response

I tried X11 as well as Wayland with kde and I3. I still experienced issues (also X11 kde would lag a lot for me and make my fans really loud)

I installed eos with cinnamon instead of kde last night and have been using it for a bit today and I haven’t noticed any graphical bugs or lag. Although, the visual glitches usually come and go, so I’ll update in a day if I experience anything odd and if not, i’ll just stick with cinnamon.

If this is persisting through re-installs, different desktop environments and X11/Wayland, I’d have to suspect a possible hardware issue.

Are you able to test with an external display, and confirm whether the glitches appear on that also?

7

yes, i’ll test with another monitor when it starts to happen again.

also this doesn’t happen on windows, and if it were a hardware issue i’d assume it would also happen on windows.

I see that it’s rendering on the amdgpu. I do notice you have some odd kernel parameters.

ibt=off pm_debug_messages
amd_pmc.dyndbg=“+p” acpi.dyndbg=“file
drivers/acpi/x86/s2idle.c +p”

ibt=off shouldn’t be needed anymore for the nvidia gpu.

These look like they have something to do with secure boot and or disk encryption but I’m not 100% sure.

amd_pmc.dyndbg=“+p” acpi.dyndbg=“file
drivers/acpi/x86/s2idle.c +p”

Did any these kernel parameters get added by you?

9

Yes, I’d tend to agree :thinking:

10

no, i didn’t add any of those. i’m running the g14 kernel which i installed from the arch for asus laptops guide linked in my original post, so i’m assuming the custom kernel added those parameters.

(also i have tried not using the g14 kernel and i was still getting bugs)

11

Okay … because probably correct. I didn’t realize it was the g14 kernel. Is your UEFI Bios up to date?

Edit: I just checked your hardware output and yes it looks like 2024.

Maybe you could check this.
