The monitor is connected with a displayport cable.Įnable or disable the displayport 1.2 setting of the monitor doesn't change anything. My graphics card is Intel HD4600 and my monitor is Dell UP3214Q. I tried xset dpms force off/suspend/ standby, the monitor works fine after resuming. This never happened on 13.10.īooting from xubuntu 14.04 livecd or a clean installion of xubuntu 14.04 gives the same problem. I have to restart x to bring it back to work. When I turn the monitor off and on, it only shows 'no input signal'. I upgraded my xubuntu 13.10 to 14.04 recently.
