[SOLVED] X crashes on startup with LTS kernel

lomaharshana · 2020-11-19 11:33:23

Hello Everyone

I have installed nvidia proprietary driver on my Archlinux.
With the regular linux kernel, X starts fine but with lts kernel the system freezes on startup.
I tried a couple of options from https://wiki.archlinux.org/index.php/NV … leshooting wiki.
(for example 1) load nvidia module in mkinitcpio 2) add drm kernel parameters 3) install nvidia and nvidia-utils and then modprobe nvidia etc.) but to no avail.

Maybe this is red herring but comparing Xorg.log files of working and non-working systems, I found that with lts kernel there is an additional drm device getting added.
Here are the excerpts from the two log file:

Are you able to switch your tty?

Try pressing ctrl+alt+F2 If that gives you a screen where you can login via a CLI, let me know. I think I may have encountered an issue similar to yours

seth · 2020-11-19 14:34:38

You've two drm devices because you've two GPUs (optimus system?)

Please post both complete xorg logs, use code tags, https://bbs.archlinux.org/help.php#bbcode or a pastebin service.

Edit: also "pacman -Qs nvidia" and "lspci -k" (latter for an LTS kernel boot)

https://bugs.archlinux.org/task/67831 should be fixed by xorg-server 1.20.9.r21.g5c400cae1-2 currently in testing.

lomaharshana · 2020-11-19 15:21:54

@Hilariousity
Yes, I can switch to tty.

@seth
I have just one GPU so I am not sure why card1 is getting added while LTS kernel startup.

Did you maybe previously mitigate the problem using https://wiki.archlinux.org/index.php/Ke … _KMS_start for the main kernel?

Hilariousity · 2020-11-19 19:21:08

So what appears to be going wrong is that xorg is attempting to run xorg of the intel driver instead of the nvidia driver

You said you only have one videocard. That appears to be incorrect. There is likely a secondary GPU built into you mainboard

it appears you might need to install the nvidia noveau driver or nvidia proprietary driver for you nvidia graphics card.

Please note the noveau is easier to install but the proprietary driver is better if you want to play "games"

Once you have the driver installed you should load the video card driver early in the boot process using early kms by adding the name of the driver to /etc/mkinitcpio.conf as mentioned in this article here

https://wiki.archlinux.org/index.php/No … _early_KMS

@seth and @Hilariousity

Thank you very much for your quick responses.
- Yes, there is a built in graphics card on the Intel processor. Thanks for pointing it out.
- But as you can see from the log of non-LTS instance, only card0 is getting added and X starts fine with this kernel. (That's the reason I thought of mentioning this fact.)
- When I start Arch with non-LTS kernel, I still see both 'GeForce GTX' and 'Intel Core I7' options under CUDA section of Blender so adding card1 does not seem necessary for built in GPU to work
- I have already tried adding the nvidia to the mkinitcpio modules [MODULES=(nvidia nvidia_modeset nvidia_uvm nvidia_drm)]. I suppose there is no different mkinitcpio for LTS.
- I can install the noveau driver if that helps, but the question still remains: why the same set up works with non-LTS and causes problem with LTS kernel.

as you can see from the log of non-LTS instance, only card0 is getting added and X starts fine with this kernel

You end up running the modesetting driver on both GPUs, what's weid, since you've the nvidia drivers intalled and there's

a) please read up https://wiki.archlinux.org/index.php/NVIDIA_Optimus decide how you intend to use the system and configure it accordingly
b) check the nvidia outputclass config

grep -r nvidia /{etc,usr/share}/X11/xorg.conf*

c) What if you start X11 dealyed (boot the multi-user.target, link in my signature, and startx or your DM from there)?
d) Let's see whether the modules are actually in the initramfs

lsinitcpio /boot/initramfs-linux-lts.img| grep nvidia

Sorry for the late reply.
There was an upgrade of linux-lts available yesterday. After I upgraded my system things seem to be fine now.

Thank you very much for your help.

Did the update also contain xorg-server 1.20.9.r21.g5c400cae1-2?

lomaharshana · 2020-11-25 12:22:14

@loqs

Maybe, I did not see the entire list of updates.

But sadly the LTS kernel is again giving the same error today. That's really strange.

You can find the log of package updates in /var/log/pacman.log. You can also check the current version of a apckage with pacman -Q e.g. `pacman -Q xorg-server`
If xorg-server is not on version 1.20.9.r21.g5c400cae1-2 please try updating the system.

Yes, I just checked as per your suggestion and the xorg-server version is indeed 1.20.9.r21.g5c400cae1-2.

We're back to "please configure the optimus system" (#9)
Also you don't have "nvidia-drm.modeset=1" in the kernel commandline anymore.

I changed the grub.conf to include this kernel parameter and the LTS seems to be working fine now.
Thank you!

Do I still need to configure optimus?
I looked at the archwiki and this option looks to be specific to laptops but I have a desktop.

NVIDIA Optimus is a technology that allows an Intel integrated GPU and discrete NVIDIA GPU to be built into and accessed by a laptop.

seth · 2020-11-28 13:17:09

Desktop or notebook - you've two GPUs and you probably want to control which one's used.
Since you don't care about battery life and assuming you can attach the outputs to the nvidia chip, you want to go w/ nvidia only. The easiest way should™ be to disable the intel chip in the BIOS.

lomaharshana · 2020-11-29 05:34:27

Ok. I will try configuring optimus and if there are any issues (that can't be solved by referring to the wikis), I will post them in a separate topic.

Thank you so much @loqs @seth @Hilariousity for your help!

Please always remember to mark resolved threads by editing your initial posts subject - so others will know that there's no task left, but maybe a solution to find.
Thanks.
