I don't think I'm up to trying a chroot, what can I do do recover

The rescue is trivial nowadays and the process is described on our wiki. It boils down to this:

Code: [Select]

# mount /dev/YOUR-ROOT-PARTITION /mnt
# artix-chroot /mnt
# mkinitcpio -P
# grub-install --recheck /dev/sda                                                   # for BIOS systems
# grub-install --target=x86_64-efi --efi-directory=/boot/efi --bootloader-id=grub   # for UEFI systems
# grub-mkconfig -o /boot/grub/grub.cfg
# exit

Reboot and profit.

Try a rEFInd iso

My laptop is EFI  (or both), my desktop is only Legacy-BIOS. Not sure what that iso does.

Merci.  When I first read 'trivial' I saw red but when I read artix-chroot I saw green. I had to find out and did :-)  This is a great little tool, thank you devs!  (BTW I think grub-install 'includes' grub-mkconfig...?)

Unfortunately the results are mixed:

On my T480  laptop everything went fine, new install from the 2023 KDE-Live dvd, full update, 1920x1080 resolution, just pointed it at a copy of my desktop /home/user directory and all is fine.

On my desktop (where the last update including a grub failure and warning had led to disaster) it's another story. I recopied that partition and did the suggested artix-chroot footwork which made it bootable but only to a black screen. Did another artix-chroot and updated it in the hopes of a fix but no cigar. Another partition got a new installation and a full update but it coughs up only a 1024-resolution, it's the only one available in the KDE hardware settings dialog. Somewhere I saw "because of Wayland" but I don't recall EVER having set wayland instead of X11.

My mistake.
rEFInd is a boot manager which auto discovers bootable EFI OS installations on a computer.
So handy to recover from broken grub situations without the need to chroot if you have it on a USB or CD. It can also replace grub.itha; one cr one can never have enough boot-aids around :-)

You may need to try a different kernel (try linux-lts); also, I saw you're using nouveau, you'll probably have better luck if you use nvidia instead, if you have a new card. Don't change both at once, begin with nvidia.

Well, he was right you know...
