[résolu] Problem with dual screen

arno · 2020-05-15 20:58:36

Hello
I'm French so if you don't understand everything about my message, you have to go after Google translation!
I have a problem when installing a second screen. I now have an HDMI screen and a VGA screen. When I plug them in, both are cloned. Now I want them to communicate, like a single screen.
So I launch Arandr to organize the two screens, side by side.
I even save the new configuration in a .sh file in the .screenlayout folder
But when I restart the computer, this new organization is not taken into account. My two screens are cloned again.
How to make so that my new organization is taken into account at startup?
If you have a solution, I'm interested !!
Thank you
Arnaud

Did you set the .sh file as executable?

8bit

You must include the screensaver script in your Openbox ~/.config/openbox/autostart. For example

./.screenlayout/filename.sh

Also, you need to add a call to the script in your autostart file (helium ~/.config/openbox/autostart, lithium ~/.config/bunsen/autostart).

EDIT Beaten by Damo, except for the reminder that Lithium is different.

Hello
I checked your proposals:
- when I right click on the icon of the file I created (which I named "config1.sh") - property, the box "allow this file to be executed as a program is checked
- I added this line in my autostart: /home/arno/.screenlayout/config1.sh

And it still doesn't work?
Damn .... I don't see where it gets stuck?
In all thank you!

From the start:

You can set up xinerama (multidisplay as one monitor), with the program ARandR, but it is not persistent?
If you after reboot when monitors in cloned mode, what if you copy the contents of your monitor-skript in an terminal? Does that shift mode back to xinerama?
Do you use correct autostart file? Do you have anyting else autostarted, you can identify is started from autstatfile (like "lxterminal").

Does it work when you apply the settings manually?
Try the script, but also try the xrandr command inside the script to see what it spits out.

If the executable script is not in your $PATH, then you need to start it with the dot notation, as I showed earlier

./.screenlayout/config1.sh

So there, it's a very strange thing ....
Writing the line: ./.screenlayout/config1.sh in the autostart file didn't change anything for me.
So I started to doubt the proper functioning of the autostart file itself!
To check, I uncommented a line:
Instead of:
## Launch guake
guake
## set up the double screen
./.screenlayout/config1.sh

I wrote:
## Launch guake
## guake
## set up the double screen
./.screenlayout/config1.sh

And there it works !!! strangely, the fact of having gone from:
guake
at
## guake

has allowed the dual screen to work as I want.

It's mysterious isn't it?

Not really. You were starting a process without forking it, so nothing else would happen until the guake process finished. If you had done this...

## Launch guake
guake &
## set up the double screen
./.screenlayout/config1.sh

or possibly better to arrange the screens first:

## set up the double screen
./.screenlayout/config1.sh
## Launch guake
guake &

The script doesn't need the ampersand, because it exits as soon as its command has completed.

Indeed .... that's it it works !!
Thanks a lot for your help. And suddenly, today, I understand a little better how my "system" works and it's cool !!
Thanks again
Arnaud
