[solved] intel graphics: output eDP1 missing after kernel update

Hi @ all,

after updating from linux 4.10.13-1 to linux 4.11.5-1, the internal display of my laptop is no longer recognized and the screen stays black. Same issue with linux-lts 4.9.32-1. I ssh'd into the machine to investigate:

$ ls -l /sys/class/drm
total 0              
lrwxrwxrwx 1 root root    0 Jun 16 00:26 card0 -> ../../devices/pci0000:00/0000:00:02.0/drm/card0
lrwxrwxrwx 1 root root    0 Jun 16 00:26 card0-HDMI-A-1 -> ../../devices/pci0000:00/0000:00:02.0/drm/card0/card0-HDMI-A-1
lrwxrwxrwx 1 root root    0 Jun 16 00:26 controlD64 -> ../../devices/pci0000:00/0000:00:02.0/drm/controlD64
lrwxrwxrwx 1 root root    0 Jun 16 00:26 renderD128 -> ../../devices/pci0000:00/0000:00:02.0/drm/renderD128
-r--r--r-- 1 root root 4096 Jun 16 00:28 version

Running linux 4.10.13-1, I get

$ ls -l /sys/class/drm
total 0
lrwxrwxrwx 1 root root    0 Jun 16 00:38 card0 -> ../../devices/pci0000:00/0000:00:02.0/drm/card0
lrwxrwxrwx 1 root root    0 Jun 16 00:38 card0-eDP-1 -> ../../devices/pci0000:00/0000:00:02.0/drm/card0/card0-eDP-1
lrwxrwxrwx 1 root root    0 Jun 16 00:38 card0-HDMI-A-1 -> ../../devices/pci0000:00/0000:00:02.0/drm/card0/card0-HDMI-A-1
lrwxrwxrwx 1 root root    0 Jun 16 00:38 renderD128 -> ../../devices/pci0000:00/0000:00:02.0/drm/renderD128
-r--r--r-- 1 root root 4096 Jun 16 00:38 version

The laptop is an Asus Zenbook UX305U:

$ lscpu | grep "Model name"
Model name:            Intel(R) Core(TM) i5-6200U CPU @ 2.30GHz

$ lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation HD Graphics 520 (rev 07)

I haven't had the time to test kernel versions in between, but will do so tomorrow. It seems, it has nothing to do with xf86-video-intel, I uninstalled it, rebuilt the initramfs and rebooted. The problem persists.

Is anyone having similar issues? Any advice appreciated.

Cheers,
Marcus

I've found out, that 4.11.4-1 is still working. Filed a bugreport: https://bugs.archlinux.org/task/54471.

I ran into the same issue, for now I solved it by enabling CSM in the bios, it seems to work fine with 4.11.5

Re: [solved] intel graphics: output eDP1 missing after kernel update

I ran into the same issue with the same laptop.
The bitsikas's solution worked also for me. My previous solution was to install the previous linux-4.11.3-1 package.
