Enable “Open as Admin” in Nautilus File Browser

Last updated: February 15, 2018

gnome shell

It’s been a long time last time I wrote about how to enable “Open as root” or “Open as Administrator” in Nautilus’ context menu.

A Nautilus extension called Nautilus Admin has been created for a period of time. It’s a simply Python script that adds some administrative actions to the right-click menu:

  • Open as Administrator: opens a folder in a new Nautilus window running with administrator (root) privileges.
  • Edit as Administrator: opens a file in a Gedit window running with administrator (root) privileges.

To install the Nautilus extension:

The extension is available for all current Ubuntu releases: Ubuntu 14.04, Ubuntu 16.04, Ubuntu 17.10, and Ubuntu 18.04.

1. Simply open “Terminal” either via Ctrl+Alt+T or from app launcher. Then run command:

sudo apt-get install nautilus-admin

Input your password (no visual feedback while typing) when it prompts and hit Enter.

2. Then restart Nautilus via command:

nautilus -q

That’s it. Open nautilus file browser again and enjoy with new context menu options!

Enable Fn Keys on HP Essential Laptops & Ubuntu 16.04

Last updated: February 12, 2018

HP Linux Imaging and Printing

I’ve bought a cheap laptop HP 246 G6 recently. As expect, Fn + function keys are not working after installing Ubuntu 16.04 on it.

So below is the quick fix how to enable the Fn keys on this laptop which may work also on other HP essential laptops.

1. First open terminal either via Ctrl+Alt+T or by searching for ‘terminal’ from app launcher. When it opens, run command:

sudo -H gedit /etc/default/grub

Input your password (no visual feedback) when it prompts and hit Enter.

2. The command opens the grub configuration file with gedit text editor.

There find out the line says:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

and change it into:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_osi="

3. After saving the changes. Update grub bootloader via command and reboot:

sudo update-grub

4. If F1 to F12 function keys are working even without pressing Fn:

Restart and press F10 to go to BIOS, disable “Action Keys Mode” in System Configuration tab.
