Second Monitor stays black/in power save mode
- by Rob
I'm using two Monitors, a Belinea o.display 1 (Recognized as a Rogen Tech Distribution Inc 20" by Ubuntu, but working fine) on the DVI-Output (connected via DVI-to-VGA-adapter) as my primary Monitor and a Dell 19" (Recognized correctly) on the HDMI-output (via HDMI-to-DVI adapter) as secondary monitor. The graphics controller is a GeForce 9500 GS.
I'm running a fully updated Ubuntu 13.04 with nouveau 1:1.0.7-0ubuntu1.
The problem is that the second monitor (Dell) never seems to come out of standby during boot: the screen stays black and the status led on the monitor stays orange (it's green when it's on). It is correctly recognized an the size of the desktop is set accordingly, it just stays black. Changing any setting via xrandr/arandr/etc. does nothing. The on-screen-menu of the monitor reports it to be in power save mode.
When using the proprietary NVIDIA-Drivers, the second monitor works just find. But these drivers cause a lot of other problems on my system, so i would really like to avoid them.
On Ubuntu 12.10 i had found a workaround:
When moving the relative position of the second monitor slightly down and the up again, it would turn on and function normally:
xrandr --output DVI-I-1 --mode 1680x1050 --pos 1280x0 --rotate normal --output HDMI-1 --mode 1280x1024 --pos 0x88 --rotate normal
sleep 2
xrandr --output DVI-I-1 --mode 1680x1050 --pos 1280x0 --rotate normal --output HDMI-1 --mode 1280x1024 --pos 0x0 --rotate normal
This workaround stop working after the update to 13.04, and now i'm looking for a new solution.
Has anyone experienced something similarity?
