Hello,
I've got an external monitor attached to my laptop.
By adjusting the settings, I can set it to be to the left of my laptop screen.
But when I shut down and restart, these settings are lost, although I explicitely applied and saved the settings.
It starts up with mirroring the main screen on the laptop.
Why does it not save those settings and applies them when the external monitior is attached/active?
There is a
similar thread, but it grew old, so I may also refer to this one as a similar problem of settings ot being stored.
What is your desktop?
Hello,
It's Openbox
Every desktop environment save it with no problem, but a window manager needs to store such settings manually, there is a solution on our wiki:

Right:
So it's ID the monitors with a xandr query:
$ xrandr -q
Screen 0: minimum 8 x 8, current 2048 x 768, maximum 32767 x 32767
LVDS1 connected primary 1024x600+1024+0 (normal left inverted right x axis y axis) 220mm x 130mm

Then generate a modeline:
LVDS

VGA1

Having read the manpage for xandr I wonder
- how do I make the additional monitor options, only when attached?
- what is the syntax for modifying two screens (6 separate lines? How will they be read?)? Unfortunately the manpage doesn't show multiple screen examples. But it does mention the positioning option.
- and the settings are currently set for both screens, so it seems I need to reverse to default to make these changes (or not?)?
Haven't done anything, don't want to mess it up...
