hard gpu driver problem

hello,

since the last update, my screen of my laptop is total freaking out.

when in console mode, brightness is changing from time to time.

when i start x, screen is going on and off, resolution seems to change and so on.

i have sshd on my laptop, so that i am able to post some info.

lsmod | grep i9

Re: hard gpu driver problem

Please use code tags, see https://bbs.archlinux.org/help.php#bbcode .

What is your default videocard, intel or nvidia ?
Are you using nvidia or nouveau drivers ?

Re: hard gpu driver problem

Sure, re-coded.

Hmm, I guess I am using the igpu.
at least, i removed all nvidia drivers, and i dont have any other xf86-*driver packages installed.
how to clearly determine which driver is used?
i see kernel mod i915 is loaded

Re: hard gpu driver problem

good eve,

using lts kernel right now, problem not present anymore

pacman -R linux
pacman -S linux-lts
mkinitcpio -p linux-lts
grub-mkconfig
grub-install /dev/sda

guess its kernel bug in linux 4.5.x

Re: hard gpu driver problem

you are aware you can have linux and linux-lts installed together ?
All you need is seperate boot-entries in your bootloader so you can choose which one to boot.
