Kernel update broke 2 monitor setup

Hi,
today i updated after a few weeks. After that my second monitor was black.

sudo pacman -U linux-5.2.11.arch1-1-x86_64.pkg.tar.xz linux-api-headers-5.1-1-any.pkg.tar.xz linux-firmware-20190815.07b925b-1-any.pkg.tar.xz solved the problem.

Someone else experience this issue? Already read another post with someone having the problem.

Re: Kernel update broke 2 monitor setup

Please provide the link to the other thread,  along with details of your system and what should be displayed on the second monitor.
Edit:
linux-api-headers is almost certainly not related.

Re: Kernel update broke 2 monitor setup

I have the same problem too. My hardware is :
lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation HD Graphics 530 (rev 06)

I solve the problem Downgrading the kernel
sudo pacman -U linux-5.2.14.arch2-1-x86_64.pkg.tar.xz

Re: Kernel update broke 2 monitor setup

@jalmmor is that not a work around rather than a fix?

Re: Kernel update broke 2 monitor setup

I think that is a bad solution.
For update the system is necessary exclude the kernel and execute pacman with the option "--ignore linux"

As you said, it is a workauround, not a fix. @loqs it's just a simple two monitor setup. System was not recognizing the second monitor after updating. Since a kernel downgrade "solved" the problem, i'm assuming the new kernel version was responsible. When the same problem occurs after updating again, i will send information output.

Maybe next Kernel version will work again. We'll see.

You could try https://aur.archlinux.org/packages/linux-mainline/ to see if it has been fixed for the next kernel version.
