Hi all, I hope I have found the right forum for asking my question -- apologies if that's not the case. I have a Dell U2412M connected to a Dell StudioSlim 540s, with the i915 driver on Fedora's 3.9.6 Kernel running KDE (4.10.4). The monitor is connected via an HDMI cable, with a DVI adapter to the monitor. When booting up my machine into X or waking it from sleep, things work perfectly. However, when I turn off the monitor (or whenever it turns itself off, if configured to do so) while the PC keeps running, I have a hard time getting the monitor to work when turning it on again. One of three things happens:
(1) The monitor pops up a message saying that "The current input timing is not supported by the monitor display. Please change your input to 1920x1200@60Hz". (2) The expected desktop contents appear on screen, but only for a fraction of a second. Then the monitor goes blank again for a few seconds, and this iterates until I turn it off again. (3) Things work as expected, but unfortunately only after turning the monitor on and off on the order of a dozen times. Even then, the configuration is a bit wonky (for example, xrandr shows all connections disconnected). I have the monitor configured to 1920x1200@60Hz both in KDE's settings and via variations of an xorg.conf (including no xorg.conf) in which I expressly state that this is what my monitor needs. I'm wondering if the problem might be HDMI-related and whether it sounds familiar to folks on this list. Any help is welcome.
