[Solved] Issues installing KDE on Arch

[queen sluice]

Hi! I’ve just performed my first manual installation of Arch Linux (being guided). After being given instructions to install KDE plasma and SDDM, I am still unable to access the desktop. I have attached a picture of the systemctl status of SDDM, and the error message when trying to load KDE.

Idk wtf to do

@queen sluice do you have an nvidia card?

[queen sluice]

Yes

[mossy forge]

Then add nvidia nvidia_modeset nvidia_uvm nvidia_drm to your initramfs modules

[queen sluice]

Where is that located again?

[mossy forge]

In /etc/mkinitcpio.conf

Once you do that

Regenerate your initramfs

And reboot and try again

[queen sluice]

I don’t see where to add modules

[mossy forge]

In this file there is a line with MODULES=""

[mossy forge]

Add these in it

It's at the beginning of the file

[queen sluice]

How so?

I’ve tried and um

[mossy forge]

sudo mkinitcpio -P

Try with sudo

[queen sluice]

Made no difference

I’m using btrfs if that’s needed

[mossy forge]

ls /boot

[mint path]

Did you edited mkinitcpio?

[queen sluice]

Yes

[mossy forge]

What does this output

[mossy forge]

You sure you have sudo installed

[queen sluice]

Yep

[mossy forge]

Try using su then run mkinitcpio -P

[queen sluice]

I don’t have a root password

I have sudo installed

[mossy forge]

Is your boot partition mounted?

lsblk -f

[mossy forge]

Reinstall the kernel

sudo pacman -S linux

[queen sluice]

Why?

I did that, btw

Reboot?

[mossy forge]

Yes

[mossy forge]

Cuz the compressed image vmlinuz is not present in /boot

[queen sluice]

Oh

Also it did nothing, it’s still hanging

[mossy forge]

Same as this?

[queen sluice]

Yep

I’m pretty sure the boot loader is the EFI boot stub, and not grub or Systemd

Idk if that’s helpful, so there

[mossy forge]

You edited /etc/mkinitcpio.conf right?

[queen sluice]

Yes

@mossy forge here

[mossy forge]

Do you have an iGPU?

[queen sluice]

What’s that?

[mossy forge]

Nvm

Idk maybe post your xorg log

.s paste

[lofty wind]

Paste short snippets, up to a few lines, in channel. Please do not use pastebin.com or paste.ubuntu.com; some good, sane paste services are ix.io, paste.rs, bpaste.net, and gist.github.com.
See .s ix or .s rs for an easy way to paste from a pipe.

[queen sluice]

where is this?

[mossy forge]

/var/log/Xorg.0.log

[mossy forge]

Paste it in one of these

And send the link here

[queen sluice]

how do I paste it? do I need to manually type this?

[mossy forge]

cat /var/log/Xorg.0.log | curl -F 'f:1=<-' ix.io

It will output a link. Send it here

[mossy forge]

Have you properly installed the nvidia driver for your gpu?

[queen sluice]

I believe so

sudo pacman -S nvidia-open, as told in #tech-general

[mossy forge]

I really suggest installing the proprietary driver

Nvidia open source drivers suck

[queen sluice]

so remove the open driver, and install the proprietary one?

[mossy forge]

Yeah

What card do you have

[mossy forge]

@queen sluice

[queen sluice]

GTX 1660 Ti

[mossy forge]

Install the nvidia package and remove kms from the HOOKS in /etc/mkinitcpio.conf if it is present. Then reboot and you should be good.

[queen sluice]

I didn't see kms

[mossy forge]

Just install nvidia then

and reboot

Then try again with the proprietary driver to see if it resolves your issue

[queen sluice]

...nope

same error

oh wait kms is there

I'll remove that

[wise yarrow]

that isn't the nvidia open source driver

that's the proprietary nvidia drivers with open source kernel modules

[queen sluice]

Nothing happened

[mossy forge]

Still they have issues

[queen sluice]

I still have the error

[queen sluice]

do I need to do this?

[mossy forge]

After removing kms you need to regenerate your initramfs

[mossy forge]

Yes

[queen sluice]

oh

[mossy forge]

Should have specified, sorry

[wise yarrow]

what's with the initramfs-linux (folder) and vmlinux-linux in your boot folder?

[queen sluice]

I was following instruction

[queen sluice]

I still have the error

[mossy forge]

Did you reboot?

[queen sluice]

yes

[mossy forge]

Got no more ideas, maybe something changed in the xorg log

paste it again maybe

@wise yarrow I was able to load a KDE plasma session using the Manjaro KDE live iso I have laying around. KDE still does not load on Arch

do you happen to know what drivers Manjaro uses?

I did boot with Open Source Drivers, but here was the result:

why is it upside down?
