How to install dual monitor command file permanently

[Cariboo1938]

Yipes! I've used this method successfully on a number of occassions. Sorry you had to resort to a full re-install. For future reference, instead of re-installing, you could try to go to a text console (Ctrl+Alt+F1) and undo the change or, if the text console is unavailable, boot into recovery mode and undo the change.
Looking at your screenshots, the issue may have been the ownership and permissions of the file. You have:
...I would have left it at the default:

-rwxr-xr-x 1 1 root root 136 ...etc

...as I believe the script is run by the lightdm user, who would not have had access to that file with the permissions you set. It might have hung the process.

I got a little further....No dead lock after 'Restart' ...but still not permanent. I had to run Arandr again to get the Dual Monitor setting.

It seems there is still something missing, but I can't figure it out.
I attached the screenshots of Ownership/Permission and lightdm.conf and the screenlayout.sh file. I'm just wondering if it is necessary to make lightdm.conf executable too?

Lightdm.conf does not need to be made executable.

Instead of running arandr to fix the issue, can you instead run:

/usr/local/bin/screenlayout.sh

...and see if it sets up the monitor configuration correctly?

There are also lightdm log files in /var/log/lightdm. Of interest would be lightdm.log. You'll need root privledges to view the file. Try:

sudo -i mousepad /var/log/lightdm/lightdm.log

...to view the file. Copy the contents and paste back in between [code] [/code] tags.

I put the screenlayout.sh on the Desktop and after boot, when I get the mirrored monitors only,
I execute the .sh file dirctly from there.
It does the same as running /usr/local/bin/screenlayout.sh from the terminal.

There are also lightdm log files in /var/log/lightdm. Of interest would be lightdm.log. You'll need root privledges to view the file. Try:

Here is the lightdm log-file

Can you also try adding:

session-setup-script=/usr/local/bin/screenlayout.sh

...to the end of /etc/lightdm/lightdm.conf?

[Cariboo1938]

Can you also try adding:

session-setup-script=/usr/local/bin/screenlayout.sh

...to the end of /etc/lightdm/lightdm.conf?

Nope, didn't do the trick...

As you can see, the file screenlayout is located in /usr/local/bin
and the end line of line ightdm.conf is now

session-setup-script=/usr/local/bin/screenlayout.sh

but I still have the same display on both monitors.

[Toz]

Hmm.

Can you try putting the command in .xprofile in your home directory?

mousepad ~/.xprofile

...and copy/paste:

#!/bin/sh
xrandr --output VGA-0 --mode 1920x1080 --pos 0x0 --rotate normal --output DVI-0 --mode 1920x1080 --pos 1920x0 --rotate normal

...save the file and make it executable:

chmod +x ~/.xprofile

...and try it again?

[Cariboo1938]

nope...I again have to execute screenlayout.sh (in my case,from /home/jg/Dektop) after a reboot.
Do I have to bring lightdm.conf first back to the originale state?

[Toz]

The .xprofile file is owned by root in your home directory - this one should be owned by you. Try:

sudo chown jg:jg ~/.xprofile

...and try again.

I've used the lightdm procedure successfully in the past. If I have time today, I'm going to hook up my external monitor to my 13.10 install and have a closer look. Maybe there has been some sort of regression in lightdm.

[Cariboo1938]

Still not working...
BTW:
I thank you so much for your patience and support...I am really interested how to solve the issue

[Toz]

Was able to do some testing this morning.

xrandr in the lightdm configuration files no longer works for me either - must be a regression (or change) in lightdm.

.xprofile worked for me. My .xprofile file:

#!/bin/bash
xrandr --output DP2 --auto --right-of LVDS1

..and:

$ ls -al  |grep xprofile
-rwxr-xr-x  1 toz  toz    132 Oct 30 10:36 .xprofile

Can you try with a small delay in the file and using the bash shell:

#!/bin/bash
sleep 3
xrandr --output VGA-0 --mode 1920x1080 --pos 0x0 --rotate normal --output DVI-0 --mode 1920x1080 --pos 1920x0 --rotate normal

Also check your ~/.xsession-errors file for any xrandr errors:

cat ~/.xsession-errors
