Hi !

Thanks for your time!

terdon

No problem :)

One sec

54N1

So xrandr --output LVDS-0 --off works, xrandr --output LVDS-0 --auto --right-of MI-0 does not turn it back on but xrandr --output LVDS-0 --auto does.

terdon

But the screens are mirrored, right?

54N1

when I use xrandr --output LVDS-0 --auto

They get mirrored

terdon

Do any of the commands give error messages?

54N1

13:13

$ xrandr --output LVDS-0 --auto --right-of MI-0
xrandr: cannot find output "MI-0"

terdon

@54N1 Cool, try with --output "HD MI-0" instead

54N1

ok a sec

sani@saniscomp:~$ xrandr --output LVDS-0 --off
sani@saniscomp:~$ xrandr --output HD MI-0
xrandr: unrecognized option 'MI-0'
Try 'xrandr --help' for more information.
sani@saniscomp:~$ $ xrandr --output HD MI0 --auto --right-of MI-0
$: command not found
sani@saniscomp:~$ $ xrandr --output HD-MI0 --auto --right-of MI-0
$: command not found
sani@saniscomp:~$ $ xrandr --output HD-MI-0 --auto --right-of MI-0
$: command not found
sani@saniscomp:~$ $ xrandr --output HDMI-0 --auto --right-of MI-0
$: command not found

EHm

could u specify the command please :P

terdon

No, I meant with the quotes (and never include the $):

xrandr --output "HD MI-0" --auto --primary --output LVDS-0 --auto  --right-of "HD MI-0"

54N1

sani@saniscomp:~$ xrandr --output "HD MI-0" --auto --primary --output LVDS-0 --right-of "HD MI-0"
warning: output HD MI-0 not found; ignoring

terdon

Dammit. That's strange

Try xrandr --output "HDMI-0" --auto --primary --output LVDS-0 --right-of "HDMI-0"

54N1

:/ the second screen is a built in laptop screen

terdon

@54N1 Which one, the LVDS I assume right?

54N1

The 24inch small one we are trying to activate back by command

xrandr --output "HDMI-0" --auto --primary --output LVDS-0 --right-of "HDMI-0" gives no result

sani@saniscomp:~$ xrandr --output "HDMI-0" --auto --primary --output LVDS-0 --right-of "HDMI-0"
sani@saniscomp:~$

terdon

@54N1 But no error? Good.

54N1

:D

terdon

Does this turn the screen off?

xrandr --output "HDMI-0" --off

I want to make sure that the screen's identifier is actually HDMI-0

54N1

13:20

That turned off the main screen 27" wich was the only one on lol

but yes it turns of the main one :)

terdon

@54N1 OK, so the HDMI-0 is the correct identifier.

54N1

Yes :)

terdon

OK, gimme a sec to try something

54N1

Cool

:)

terdon

@54N1 what exactly is your desired setup? Should the external (HDMI) screen bethe primary? Which one should be to the left of which?

54N1

13:25

Yes when the HDMI is connected I rarely want to use the laptop screen

The HDMI 27" is to the left

terdon

So when both are on, you'd like your desktop to be extended to the laptop's right?

54N1

No to my laptops left

My laptop is right of my screen

terdon

@54N1 Sorry, I meant you'd like your desktop to be extended to the laptop's correct?

54N1

Yes

And the hdmi 27 to be the primary

terdon

OK, does this work?

xrandr --output HDMI-0 --auto --primary --output LVDS-0 --mode 1920x1080 --right-of HDMI-0

If not, try this:

xrandr --output HDMI-0 --auto --primary --output LVDS-0 --mode 1920x1080+1920+0

54N1

13:29

YES!!!!

terdon

:)

54N1

RESPECT

terdon

Which one, the first?

54N1

sani@saniscomp:~$ xrandr --output HDMI-0 --auto --primary --output LVDS-0 --mode 1920x1080 --right-of HDMI-0
sani@saniscomp:~$ xrandr --output LVDS-0 --off
sani@saniscomp:~$ xrandr --output HDMI-0 --auto --primary --output LVDS-0 --mode 1920x1080 --right-of HDMI-0
sani@saniscomp:~$ ^C

Turned it off and then back on how I want it to be

terdon

Perfect!

54N1

13:29

:D

terdon

@54N1 OK, I updated my answer with the correct command. You should be able to set the keyboard shortcuts now.

54N1

ok I will try it now

hm the post is not update

d

terdon

Just reload the page, I can see the update on mine, I only changed one line in the script

54N1

I know this is a really beginers question, but how do I save the script do I just enter it into the terminal

like this I mean

sani@saniscomp:~$ #!/usr/bin/env bash
sani@saniscomp:~$
sani@saniscomp:~$ if [[ $1 = "off" ]]; then
> xrandr --output LVDS-0 --off
> else
> xrandr --output HDMI-0 --auto --primary --output LVDS-0 --mode 1920x1080 --right-of HDMI-0
> fi
sani@saniscomp:~$ ~/switch_screens.sh off

lol

sorry it says exactly how in your post

54N1

13:53

Evrything works from the command promt the only thing not working is the keyboard shourtcuts

terdon

14:32

@54N1 Sorry, I was away. How did you set the shortcuts? try using the full path instead of ~/

So, if your home directory is /home/54N1 and the script is at /home/54N1/switch_screens.sh use /home/54N1/switch_screens.sh in the shortcuts
