[Solved] Arch doesn't boot after updates

Kromes · 2016-09-17 11:12:00

Hey guys,

Booted up arch this morning and ran

sudo pacman - Syu

as well as installing a few apps.

The only other thing I did in the session prior to the problems is create a Xresources file, which I deleted just in case via my Mint install.

Grub begins launching Arch and I get the ram disk messages, but then all I get is a black screen.
Not sure what diagnostics I can post to help solve the problem, being as I can't load Arch.

Any help would be really appreciated.

Try disabling kernel modesetting.

I've tried adding

nomodeset  i915.modeset=0

to my launch parameters in grub to no avail.

Fixed the problem by downgrading the kernel. Does anyone know if there's a way to update without changing the kernel? How can I avoid this problem? I want to be able to run

pacman - Syu

without fear of killing arch

No. Partial upgrades are unsupported

Read your journal from the failed boot and find out what went wrong.

Did you try just "nomodeset" by itself?

Rather than using an outdated kernel, you should switch to the LTS version.

I've switched to lts kernel. I had a few problems with this, it turns out typing grub-mkconfig is not enough. Like a total noob I simply thought that grub-mkconfig is exactly the same as grub-update. Idiot. If anyone has a problem updating the kernels or their grub set up try:

grub-mkconfig - o /boot/grub/grub.cfg

Switching to lts kernel fixed my boot display issues. Solved, thanks guys.
