 |

Hi there,
Unsure if this fits in this section or "Kernel and Hardware" instead..
I am facing a weird issue after reinstalling my laptop : the video modes for my primary display are wrong (4:3 ratio instead of 16:9). The maximum resolution is detected correctly (3840x2160) but all the others are wrong:

3840x2160 60.00*+
2048x1536 60.00
1920x1440 60.00
1856x1392 60.01
1792x1344 60.01
1600x1200 60.00
1400x1050 59.98
1280x1024 60.02
1280x960 60.00
1024x768 60.04 60.00
960x720 60.00
928x696 60.05
896x672 60.01
800x600 60.00 60.32 56.25
700x525 59.98
640x512 60.02
640x480 60.00 59.94
512x384 60.00
400x300 60.32 56.34
320x240 60.05

Now I need to use 1920x1080 on this display because I also use an external monitor that doesn't support > 1920x1080 and having a mix of 4K and HD mode is a pain since X doesn't support setting a DPI per display.
More infos :

Kernel is 4.17.9-gentoo, here's the config : http://ix.io/1j7u
I did read https://wiki.gentoo.org/wiki/Intel but haven't found an answer.

This used to work correctly before reinstalling, but I can't figure out what's wrong.
Thanks for your help!

Also I was able to use 1920x1080 before reinstalling.
One thing i noticed is that the name of my devices changed :
eDP1 became eDP-1 and DP1-2 became DP-1-2.. I don't know if this is relevant...

| Maybe you used the intel driver before, now you're using the modesetting driver? |
