Flashing underscore whenever I try to switch back from xanmod or lqx kernels back to latest Manjaro kernel

Hey! I have been using Manjaro for 6-7 months now and decided that I want to switch from custom kernels such as xanmod and lqx to ordinary Manjaro ones. However, I encounter flashing underscore on boot, and I am able to enter advanced grub options and switch back to custom kernels (they work straightaway). I suspect that the main problem here is the fact that I am using a Nvidia card with proprietary drivers, but not really sure how to solve this problem. Could you please help me with this issue?

> Installed PCI configs:
                  NAME               VERSION          FREEDRIVER           TYPE
     video-modesetting            2020.01.13                true            PCI
video-hybrid-intel-nvidia-prime            2021.12.18               false            PCI

please post the output of

inxi --admin --verbosity=7 --filter --no-host --width




glxinfo | grep server

note: you have to install the package “mesa-utils” first if glxinfo is missing

You need to build the Nvidia drivers as Manjaro does not provide these kernel, and of course doesn’t provide the Nvidia modules either. Not sure about your system (need to provide relevant info just saw the link to inxi), but this is probably that.

PS: there is no real benefit in using these custom kernels in my opinion. Real life use case you’ll see no difference.

inxi : inxi --admin --verbosity=7 --filter --no-host --width - Pastebin.com

Session type: tty ( x11 when using xanmod or lqx)

Glxinfo: unable to open display

Exactly! That is why I decided to get rid of them, but unable to switch to default kernel for some reason.

so please provide us with the information of glxinfo as explained above. also please use the formatting that is described below and not pastebin or any other similar.

:+1: Welcome to Manjaro! :+1:

  1. Please read this:
    [HowTo] Provide System Information
    and press the three dots below your post and press the :pencil2: to give us more information so we can see what’s really going on.
    Now we know the symptom of the disease, but we need some more probing to know where the origin lies… :grin:
  2. An inxi --admin --verbosity=7 --filter --no-host --width would be the minimum required information for us to be able to help you. (Personally Identifiable Information like serial numbers and MAC addresses will be filtered out by the above command)
    Also, please copy-paste that output in-between 3 backticks ``` at the beginning and end of the code/text.

i’m out

I don’t understand what am I doing wrong, sorry.

provide output from:
mhwd-kernel -li

It should be enough to install the current kernel sudo mhwd-kernel --install linux519 and then your nvidia drivers.

Your kernel parameters don’t look default, please remove anything that you don’t actually need (e.g. audit=0 is listed twice)

From the blinking cursor, can you switch to a TTY? Then you could also provide the journal of this boot and the Xorg.0.log file.

Hi, I will post another reply as soon as I will be back home. So far I have tried linux 515 and it works without any issue, while booting in 519 produces kernel panic. I am able to use TTY without any issues as well.

The kernel and the gpu drivers are meant for eachother. If your combination is not built to match you will get issues.

You are - of course - aware the mentioned kernels are custom built and unsupported.

If you like to play with kernels - I get it - I do too - from time to time.

I therefore suggest you ensure you install kernel headers for whichever kernel and nvidia-dkms - I think this will take the top of your issues.
