EE no screens found Linux-lts[SOLVED]

I'm trying to change my linux kernel from the normal linux to linux-lts. But whenever i try to use the LTS version of the kernel i cannot get x-org to work, it simply gives me a message of (EE) no screens found(EE), after failing to find the correct drivers.
I'm currently using a laptop with a CPU\GPU, called Radeon Vega graphics on a Ryzen 5 cpu.

I read in a post i could simply go into /etc/mkinitcpio.conf and add amdgpu inside MODULE. But this did not help much.
I tried to look into the AMD and Xorg wiki but i cant really figure out what is wrong since my normal Linux kernel seem to work just fine on boot. So this seems to me that it is some kind of LTS kernel issue, or?

Worth noting that sometimes when i try and boot from the LTS kernel it also fails to find the disk and when i power on the machine it says "no boot device found" but that is a seperate issue and something i can bypass with another reboot for now.

I must admit i am totally lost. Been trying to look in the wiki pages and former forum topics but nothing seems to work.
I'm not really an expert in Arch but i am willing to learn so if someone can point me in the right direction it would be much appreciated!

This is my X-orgLog

Re: EE no screens found Linux-lts[SOLVED]

The LTS kernel is a year old at this point from a HW support perspective, if your hardware is too new that isn't too surprising. For what reason do you want to switch (FWIW the current stable kernel will become the next LTS when we move on to 5.5)?

is xf86-video-amdgpu even installed?
are you using a custom xorg configuration? if yes then post it.

Re: EE no screens found Linux-lts[SOLVED]

It should load modesetting either way. You might want to post a complete dmesg

3rd generation Ryzen isn't supported by the 4.19 LTS branch.

That explains alot! Think i will stick to linux kernel for now then smile Reason i wanted to use LTS kernel was because i read sometthing on the arch forum, and people were saying that using normal linux kernel with virtualbox would cause it to break alot.
I guess i will just learn how to deal with it if it happens instead and get more into the arch ethos sooner than later smile

Yea xf86-video-amdgpu is installed, but i think the problem is what the others pointed out that the linux LTS dont support the 3rd generation Ryzen, that was the issue smile
