I don't find an option to mirror my Displays on Ubuntu 18.04:
I am running Ubuntu on a Dell M3800 with hybrid graphics.
What might cause this?

where is display one - it only shows 2 and 3 , or better said how did you connect your displays?

Display one is the built in display of the notebook and it is turned of. Turning it on doesn't show the mirror option neither, displays are connected via HDMI and Mini DisplayPort (DELL M3800)

please give us more info: is it ubuntu or one of the official flavours like xfce or mate etc... - or have you installed several of these? is it still a new installation or a heavily edited and what is your grafic devicesudo lshw -c display- try running a live session from usb/dvd and check if it is the same on there.
– db429
Nov 26 at 22:35
It is not heavily edited. It is Ubuntu 18.04, no flavour.
– Alexander Zeitler
Nov 26 at 22:37
okay it is hybrid grafix - so I have no clue except to point you to: help.ubuntu.com/community/HybridGraphics or ubuntuhandbook.org/index.php/2016/04/… sorry

When booting from Live USB the options also is not avaiable.
Switching to the NVIDIA Driver 340.107 from nvidia-340 didn't fix it.

where is display one - it only shows 2 and 3 , or better said how did you connect your displays?
– db429

Display one is the built in display of the notebook and it is turned of. Turning it on doesn't show the mirror option neither, displays are connected via HDMI and Mini DisplayPort (DELL M3800)

From this answer: How can I mirror one of the screens in a 3-monitor setup? try using:
xrandr --output eDP-1-1 --output HDMI-1-2 --output HDMI-1-2 --same-as HDMI-1-1
In the accepted solution above, screen 3 is mirrored to screen 2 but the primary screen is not mirrored.
Another option is switching to Unity desktop: GNOME in Ubuntu 18.04 and multi monitor setup
Click the gear icon next to the Sign In button as shown below:
Note: Fresh 18.04 installs may need to install Unity Desktop. 16.04 Upgrades will likely have Unity in place by default. See: How can I make Ubuntu 18.04 / 18.10 desktop use Unity (be like Ubuntu 14.04)?

@AlexanderZeitler usexrandr --output HDMI-1-2 --pos 0x1920assuming monitor two sits to the right of monitor 1. The best solution is to runxrandrand not the positions before using--same-as. Of course you can always reboot too.
