I would like see the laptop screen in my Samsung TV with HDMI cable. The FN+F8 button is not working and the settings I don't see the TV, when cable is on-on.

How to?

Please help me. Thanks!

I don't see the TV, when cable is on-on

How are you checking?

I would use

Code: Select all

xrandr

Or

Code: Select all

arandr

^ That offers a nice GUI (install the arandr package).

[sjsj]

xrandr

Code: Select all

Screen 0: minimum 320 x 200, current 1280 x 720, maximum 8192 x 8192

   1280x720      59.65*+

su
xrandr

Code: Select all

No protocol specified
Can't open display :0

The arandr command not found (su and not su).

You would need to install arandr, as noted, via apt. Each desktop environment (gnome, mate, cinnamon, xfce, etc) has a display applet where this can be configured. Look for display settings. WIthout knowing your desktop environment I can't be more specific.

I think that's GNOME so try the display section of the settings panel.

Gnome.

I see only the notebook screen settings. The TV screen settings not in list.

[sgosnell]

I don't use Gnome, and I can't read the language in use by the computer, so I/m afraid I won't be of much more help.
