Dual Monitors Not Running On Startup on Mint Cinnamon 18.3


I installed Linux as dual boot on my computer a week ago and have worked out all problems but this issue to have dual monitors run on startup.

Dual monitors (primary ACER, secondary DELL) worked well under Win-7 and XP and I am able to have them both on my Linux desktop by running my LRandR terminal command after I've booted to the desktop and then plugged in the secondary monitor, but not in autostart. If I have both monitors attached to the two DVI jacks the primary monitor does not wake up... only the secondary monitor comes up and it does not have the panel on it.

Here's the output of inxi -Fxz after connecting the secondary monitor and running the following command in a terminal...
xrandr --output DVI-1 --mode 1280x1024 --pos 1680x0 --rotate normal --output DVI-0 --primary --mode 1680x1050 --pos 0x0 --rotate normal

Client: Shell (bash 4.3.481) inxi: 2.2.35

Running that command in autostart does not wake the secondary monitor... it has to be plugged into the sound card after reaching the desktop.

I'm trying to be clear but if you need any more info let me know.

Sorry if this topic doesn't belong here, but I am a Linux retread having only played with it many years ago... but I am determined to not return to MS Windows. So... I would think I am a newbie.

Thank you for any help,
Ed

The way I do this is I use "arandr". Then when the config is the way I like it I can "save" the config file. Then make sure the config file, which I have named "desktop.sh", is set to open with "bash".

Then in "session and startup" I set it to run at boot. Sometimes this doesn't work at boot so I create a tray icon that operates the "desktop.sh" file after startup.

Maybe that will give you some ideas.

Did not work... If both monitors are plugged in at startup, the main monitor goes to sleep and stays asleep while the secondary monitor only shows my wallpaper and I am not able to switch to the other monitor. If I startup with only the primary monitor then I reach my desktop as usual, but then I have to plug in the secondary monitor... then when I run my dualmonitors.ch script the secondary monitor is usable, however, the unplugging/plugging causes undue wear and tear on the DVI jack and is not a viable solution.

Nice try though... thanks,
Ed

OK, do it like you normally do. But don't set the resolution. Just let it boot up and attach the second monitor. Open gnome-control-center and make your changes there. Then, every time you log in it should be correct.

I would then try a different live distro on DVD or USB, like ubuntu, and see if that lights both monitors.

Tried that but when gnome-control-center is run only Printers and Firewall Configuration are shown.

-SOLVED-

The old Dell monitor I was using as DVI-1 was not providing EDID data when autoprobed by X server in order to find permissable video modes. Tonight I retired the old Dell and replacing it with the Acer, which was my main monitor (DVI-0). I had a newer HP monitor in storage which is now in the main (DVI-0) position and both monitors are recognized and used when I boot to the desktop. Now both are usable as my extended desktop.
