computer monitors goes into stand-by with hdmi when booting AND forciing display though replica of dvi...

#1 Post by casper :) »

my monitor will work fine with the hdmi how i have it setup if i run it with these settings...

in order for me to get a display showing my desktop with my wallpaper and my toolbar i will have to have "Replica of" my dvi output. i dont know if this is normal or not. i assume its something with X but i couldnt find much online. is there a way to set up the hdmi desktop with Replica of turned off and get my desktop to show my toolbars and such? maybe its as easy as starting kde while its in that mode but im at a loss.

also, when i boot up with my monitors input as hdmi, my screen will just stay in stand-by and i will to switch the monitors input from hdmi do dvi.

debians been great and so much fun i can't wait to keep learning ^^.

thanks!

xorg.conf has a DPMS setting in the monitors section. Unfortunately monitor vendors are free to ignore it, or as is more often the case, incorrectly implement it.

You also have the option to set a startup script with the login manager (at least with lightdm). For example in my /etc/lightdm/lightdm.conf there is a line that I modified:

display-setup-script=/etc/lightdm/monitors.sh

The monitors.sh contains the following:

Code: Select all

#!/bin/sh
# Shutoff laptop display - use only HDMI monitor
xrandr --output eDP --off
xrandr --output HDMI-A-0 --mode 2560x1440
xrandr shuts off my laptop screen since the laptop is setup as if it were a desktop computer.
Then, xrandr sets the output of the HDMI monitor to the specified DPI
So when the system boots, it will automatically turn off the laptop screen and set the external monitor before I even login.
This may not be exactly what you are looking for but if gives you a workable option.
