using xrandr to turn screen off/on like mate-display-properties
I've got 2 monitors connected to my laptop.
One is connected via HDMI and one is connected via USB displaylink. When I boot up my computer linux thinks my DL monitor is on, but the screen is black (DL is not initialized properly for some reason). The mate-display-properties fix Its easy to fix using mate's display properties widget. (similar to gnome-display-properties) Turn off DL monitor I select the DL monitor, click off, apply Turn on DL monitor Then I select the monitor, click on, move it to where I want it, click apply. Perfect! Now lets try it with the command line after a fresh reboot. Turn off DL monitor with command line xrandr --output DVI-0 --off Perfect. Now lets turn it back on... Turn on using xrandr --mode (fails) xrandr --output DVI-0 --mode 1920x1080 My system gets completely messed up and I have to reboot. The DL monitor seems to mirror my LVDS monitor. I can move the mouse around but can't click on anything or make windows get focus. Turn on using xrandr --auto (fails) xrandr --output DVI-0 --auto My system gets completely messed up and I have to reboot. The DL monitor turns on but the graphics go all corrupt, black mixed with the picture, wherever I move the mouse redraws that part of the screen. It seems to have its own space rather than mirroring. Its weird. Solution? If mate-display-properties could produce a commandline output or log for me to see what its doing I could just use the same commands? verbose xrandr output (both screens positioned and working properly) http://codepad.org/jJccaANW |

Okay I tried running mate-display-properties from a console window inside the mate session and then turning monitors on and off with mate-display-properties.
I got a segmentation fault every time. and mate-display-properties ended. I tried running it in the foreground and background (without ampersand and with). Besides the segmentation fault message, nothing else is shown. [0] % mate-display-properties& [1] 6209 [0] % [1] + 6209 segmentation fault mate-display-properties =================== Regarding HDMI vs DVI. HDMI is the native HDMI graphics output on my laptop. When I boot up that works properly. The DVI-0 is the Displaylink adapter. When I boot up the Displaylink monitor is on, but its black. It needs to be turned off and on again with mate-display-properties to get it to function normally. This is what my setup looks like in mate-display-properties http://i.imgur.com/gdZTQbI.jpg |
Do you have a xorg.conf file in /etc/X11 ?(if you do please post it) If not it could be a good thing to have it there with all monitor settings you need, so then there is no need to set it up everytime the machine is turned on.
