monitor settings not sticking

[JASpup]

Old lxrandr in Tahr works normally. It includes only the options in the Advanced tab of the Xenial version.

I'm trying to turn off my external monitor to use only the laptop LCD. When I uncheck the external box, or select this arrangement in Quick Options tab, it changes for a few seconds before reverting back to the way it was.

Changing monitor settings is like The Little Engine That Could.

I did something to get it to stick, but it's a weird, common intermittent problem. It could have been restarting JWM.

Seems like it works... then maybe not.

To turn off your external monitor:

xrandr --output HDMI-0 --off

To enable your laptop LCD:

xrandr --output LVDS --auto --primary

where LVDS is your laptop screen
and HDMI-0 is your external monitor.
The exact names for your machine may be different.
Typing xrandr will show you the names of your monitors.

Then you probably need to type fixPuppyPin

For help:

xrandr --help

If X is using the vesa driver, xrandr might not work properly.

lxrandr puts a desktop file in /root/.config/autostart/

Maybe this will work where the gui does not. My external is VGA and DVI. I use DVI for my 64 desktop and VGA on the portable 32s.

To get it to work yesterday I had to restart X.

Hope in the command line!
