My arch Linux plasma desktop is really slow

[tacit quail]

Fyi all the fixes I tried seemed a bit too confusing and I didn't understand them

I'm on like a fresh install

[willow heart]

What do you mean slow?

[tacit quail]

Like every action is really laggy

Mouse movement and anything to do with just using it

[willow heart]

Did you install your Nvidia drivers?

[tacit quail]

Really stuttery it feels like

Not too sure but I don't think so

How do I do that??

[willow heart]

You just install sudo pacman -S nvidia-open-dkms

And rebuild the initramfs with sudo mkinitcpio -P

[tacit quail]

After that I assume I restart the system right?

[willow heart]

Yes.

[tacit quail]

Got an error "specified kernal image does not exist: '/boot/vmlinuz-linux' "

When executing the second commmand

[willow heart]

Show me a screenshot.

Is it a laptop?

[tacit quail]

There's more up top

And no it's not a laptop

[willow heart]

Okay, show me the output of ls -al /boot/

[tacit quail]

Total 0

That's all it says

[willow heart]

Oh, show the output of lsblk

[tacit quail]

I put it on my sda because my nvme0 is broken just so you know my windows 11 is also on my sda just fyi

[willow heart]

No boot partition!!

[tacit quail]

I made one????

I made a boot a swap and a file system

[willow heart]

Output of cat /etc/fstab

[willow heart]

The swap is there but no boot.

[tacit quail]

??? Im so lost sda 5 is supposed to be efi if I'm not mistaken and sda 6 file system and obviously sda 7 swap

[willow heart]

Show the fstab cat /etc/fstab

[willow heart]

This is impossible. I'm puzzled by this; the fstab is empty.

[tacit quail]

Yea😭😭

Trust me this isn't something that happens to me rarely I always have the most random and unexplained issues🥲

Don't know how it's empty at all it should have at least 1 thing there no??

[willow heart]

Output of lsblk -f

[tacit quail]

Don't mind the name of the nvme🥲

[willow heart]

Let fix this.

[willow heart]

You used grub, right?

[tacit quail]

Yes

[willow heart]

Mount the boot partition sudo mount /dev/sda5 /mnt/boot

[willow heart]

Okay, just do sudo mount /dev/sda5 /mnt

[tacit quail]

Okay done I got no response in return.

[willow heart]

And run ls -al /mnt/

Show the output

[willow heart]

Okay, that look good.

[willow heart]

Now lets do it again.

run sudo umount -R /mnt

[tacit quail]

Done

[willow heart]

Run sudo mount /dev/sda6 /mnt

And run sudo mkdir -vp /mnt/boot

After that run sudo mount /dev/sda5 /mnt/boot

[tacit quail]

Don't know how I'm not a superuser even though I should be

[willow heart]

Run them with sudo.

[tacit quail]

The last 2 commands worked

[willow heart]

Show me.

[willow heart]

You didn't the first one.

[willow heart]

Is it hard to follow instructions?

[willow heart]

Run umount -R /mnt

[tacit quail]

No that is my fault I thought I used sudo with the first one my bad.

[tacit quail]

Did it

[willow heart]

Okay, run sudo mount /dev/sda6 /mnt

[tacit quail]

Done

[willow heart]

Run sudo mkdir -vp /mnt/boot

[tacit quail]

✅

[willow heart]

And after that run sudo mount /dev/sda5 /mnt/boot

[tacit quail]

Done

No output

[willow heart]

Run lsblk

[willow heart]

Run sudo genfstab -U /mnt > /mnt/etc/fstab

[willow heart]

Okay, it didn't work so lets do it manually.

[tacit quail]

Alright

[willow heart]

Run lsblk -f

[willow heart]

Copy the UUID's to here.

[tacit quail]

All of them?

[willow heart]

sda5, sda6, sda7.

[willow heart]

Run this one see if it works genfstab -U /mnt | sudo tee /mnt/etc/fstab > /dev/null

[tacit quail]

That command worked

[willow heart]

Okay, output of cat /etc/fstab

[tacit quail]

A746-9496

418760ac-2742-4996-95fc-accfc9d69734

Ea87915c-7b0a-495e-8700-e2dbca4a898a

These are the uids

Uids*

Uuids

[willow heart]

Run this cat /etc/fstab | curl -F 'file=@-' https://0x0.st and share the link.

[tacit quail]

Https://0x0.st/KjlG.txt

[willow heart]

What is your text editor?

[tacit quail]

On what?? My Linuz system?

Linux*

Not too sure

[willow heart]

Yes

[tacit quail]

KDE

Kwrite

[willow heart]

You have kate?

[tacit quail]

Yea

[willow heart]

Okay, edit that file sudo kate /etc/fstab and put in it this

# /dev/sda6
UUID=418760ac-2741-4996-95fc-accfc9d69734   /    ext4    rw,relatime    0 1

# /dev/sda5
UUID=A746-9496    /boot    vfat    rw,relatime,fmask=0022,dmask=0022,codepage=437,iocharset=ascii,shortname=mixed,utf8,errors=remount-ro   0 2

# /dev/sda7
UUID=ea87915c-7b0a-495e-8700-e2dbca4a898a    none    swap    defaults    0 0

[willow heart]

Just install nano sudo pacman -S nano and use that instead of kate

[tacit quail]

Nano is already installed

[willow heart]

Okay, just sudo nano /etc/fstab

Remove everything in there first

Then put this

# /dev/sda6
UUID=418760ac-2741-4996-95fc-accfc9d69734   /    ext4    rw,relatime    0 1

# /dev/sda5
UUID=A746-9496    /boot    vfat    rw,relatime,fmask=0022,dmask=0022,codepage=437,iocharset=ascii,shortname=mixed,utf8,errors=remount-ro   0 2

# /dev/sda7
UUID=ea87915c-7b0a-495e-8700-e2dbca4a898a    none    swap    defaults    0 0

[tacit quail]

[willow heart]

Make sure you don't miss anything.

[tacit quail]

I will don't worry

Alr typed everything in

[willow heart]

No new lines after the UUID's

[tacit quail]

Also forgot the vfat and boot but the uuids and the other things below it belong on one line?
