  • hello

    I'm not able to enable 3840x2160@60hz in ubuntu. I can see from my monitors menu (Asus PB287Q) that it is at 60hz during grub menu but immediately when ubuntu switches display it does back to 30hz.

     

    my setup:

    -asus pb287q

    -MSI Z97M-G43

    -Intel i5 4460

    -ubuntu 14.04

     

    I have tried:

    -change DP stream to 1.2 from monitors menu

    -install latest intel graphics 1.06

    -tried adding new modeline with xrandr and also added it to /usr/share/X11/xorg.conf.d/10-monitor.conf

    -tried changing output with xrandr but i get "xrandr: configure crtc 0 failed"

     

     

    xorglog:

    [   231.051] (II) intel(0): switch to mode 3840x2160@60.0 on DP1 using pipe 0, position (0, 0), rotation normal, reflection none

    [   231.585] (II) intel(0): switch to mode 3840x2160@30.0 on DP1 using pipe 0, position (0, 0), rotation normal, reflection none

    Any advice? Does this need edid quirk in drm_edid.c or something to driver? 

     

     

     

    EDIT: decode edid was garbage becasue of wrong input format... now fixed
