I want to file a bug from this but i have not idea to which compoment I should raport that?
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.
btw: Meanwhile one workaround you could try is to put the mode on xorg.conf.
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.
