[SOLVED] Integrated GPU errors after upgrading to Linux LTS

Hey,

I'm having problems with my new laptop (Thinkpad T450S) with Arch. It freezes completely maybe once a day and I thought this might have to do with the kernel somehow being incompatible with the hardware. I installed LTS but once the laptop boots into console login, the console has massive font size (which is often a GPU problem itself) and when I try to login I get a Xorg error that says there's a fatal error with i915 kernel module (TTY1 login starts X). When I try to modprobe i915 it says that module doesn't exist, which it should. I tried reinstalling the kernel (and grub-mkconfig obviously) and also I tried to reinstall xf86-intel video, but it doens't go away. For the record, this is also a new installation (two days old) because the last installation had this problem as well.

I hope someone can guide me to the right direction, I'm not sure why i915 seems to completely disappear when installing LTS as it works fine with bleeding edge kernel.

Thanks!

EDIT: this laptop hasn't got discrete graphics, only Intel HD 5500.

What is the output of the following?

pacman -Q linux-lts linux
uname -a

Hi, yes I should know better.

victor@archlinux:~% uname -a
Linux archlinux 4.20.10-arch1-1-ARCH #1 SMP PREEMPT Fri Feb 15 17:49:06 UTC 2019 x86_64 GNU/Linux

victor@archlinux:~% pacman -Q linux linux-lts
error: package 'linux' was not found
linux-lts 4.19.23-1

No errors on pacman -Rsn linux && pacman -S linux-lts && grub-mkconfig -o /boot/grub/grub.cfg.

EDIT: The problem is obvious. Apparentally there was a stupid mistake in mkconfig... Don't know how I managed to screw it up. GRUB was booting "linux" while it wasn't installed, instead of lts, which was Solved now, thanks.

Re: [SOLVED] Integrated GPU errors after upgrading to Linux LTS

The running kernel is

archlinux 4.20.10-arch1-1-ARCH

The installed package providing modules is

linux-lts 4.19.23-1

So the running kernel can not find any matching modules such as i915.
The most common cause is /boot being a separate filesystem and not being mounted when the kernel was updated.

Yep, managed to fix it. I probably made an error when using mkconfig, possibly UEFI partition wasn't mounted or something (like you said). I'm golden now. Thanks!
