  • setup:
    -asus pb287q
    -MSI Z97M-G43 (latest bios 1.5)
    -Intel i5 4460
    -ubuntu 14.04 (latest next kernel)
     
     
    I'm able to enable 3840x2160@60hz in ubuntu 14.04 with the latest kernel compiled. I use command "xrandr --output DP1 --mode 3840x2160 --rate 60 --verbose" 
     
    The problem is that if I put monitor off and then on again (or let monitor sleep), it goes back to 30hz. It also 30hz after full reboot. 60hz is preferred. How I can make 60hz really preferred so that its used after I open monitor?

    so where it gets the 30hz default for this monitor and how to override it to use 60hz everytime? seems that reading EDID fails everytime and still it

  • Hi Kari,

    extra questions pertinent here:

    Is this behaviour a regression caused by installer? Or you were facing on Canonical's kernel?

    Do you face it with upstream drm-intel-nightly and with latest xf86-video-intel? If so, 

    Regardless the component please report the issue at bugs.freedesktop.org following: https://01.org/linuxgraphics/documentation/how-report-bugs.

    as you did already for the suspend/resume leak.

    Thanks,
    Rodrigo.

  • btw: Meanwhile one workaround you could try is to put the mode on xorg.conf.

  • Hi Rodrigo,

     

    I'm using ubuntu 14.04 with mainline kernel. for example 3.17rc6 http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.17-rc6-utopic/. With the original 14.04 kernel, which is 3.13, I cant even see the 60hz option with xrandr.

     

    I have not tried to add anything to xorg.conf but instead I created /usr/share/X11/xorg.conf.d/10-monitor.conf where I had 60hz modeline. With that the booting fails.

     

    I tried drm-intel-nightly last week and it had the same problem. I have not tried with latest xf86-video-intel. How can I test that?

  • I just tried daily ubuntu 14.10 live cd (http://cdimage.ubuntu.com/daily-live/current/) and with that the refresh rate is 60hz immediately after boot and it does not change after monitor goes to sleep and wakes up.
