I've looked everywhere and I still can't find the fix fot my problem
I installed Manjara two days ago to give Linux another try and just see how it performs nowadays.
At the beginning everything seemed to be working fine, until changed kernel, although I also had problems with setting Manjaro in UEFI.
I'm trying to run it as secondary system to Windows.
I have HP laptop with NVMe ssd, UEFI, GPT and TPM, secure boot is off of course, although I can't find any fast boot options in BIOS so I'm not sure if it's even there.
I think I've looked through every guide for fixing GRUB, and correctly setting up dual boot, and still nothing worked.
To the point:
I switched kernels, pretty much just to see how that works and on next reboot, OS just got stuck on this:
But from what I've read these are harmless.
Space pointer is just flickering like crazy, and ctrl+alt+f4 console (I'll be glad to know how it's called ) is unusable. It also flickers. I was able to access terminal by editing grub settings though. I can also perform manjaro-chroot in LiveCD environment, but no luck with
mhws-chroot. Strange thing is that I can launch Manjaro in UEFI-Legacy mode, hower the screen is offset, and there are definitely many other graphics problems. But it's still somewhat usable and sometimes it even has correct colors.
Not having much to loose I decided to re-install Manjaro. I used "replace partition" option as I did the first time. After making sure everything is uptodate I changed kernel once again to see if the problem would show up again... and it did.
I re-installed Linux for third time, but this time I decided to follow this post
I followed it step by step and because of that I was also able to create correct (I think) UEFI setup.
I tested the same thing again, but this time Manjaro launched without any problems after switching kernels!!! I went back to original one and everything went smoothly again.
I started setting up system to my liking. I only installed apps like Chrome, Spotify etc. and edited theme a bit. (The first time I installed Manjaro nothing wen't wrong with that).
Then I restarted my laptop... and I was back to the start. Manjaro wouldn't boot again!
I know that the simple answer would be to just not switch kernels but I worry that if I start using Manjaro more as my main operating system that could happen again with something like system update and I would really like to avoid that. Even if not I think that having something small that doesn't work in bigger system is never a good thing.
I hope I included enough information to work with. Thanks from replies upfront anyway
P.S. EFI partition is shared by Manjaro and Windows
