VPN Passwords won't save in XFCE

In order to stop XFCE network manager dropping your saved VPN passwords, open the config files found in /etc/Network Manager/system-connections/, choose your preferred connection, and open in leafpad with:

gksu leafpad  [filename]

Add the following line:

[vpn-secrets]
password=xxxxxxxx

Where xxxxxxxx is your VPN password. Save file.

Fixing DNS leak in Manjaro

Firstly, check the file /etc/resolv.conf and see what's inside. Make sure it only contains the DNS servers you want it to contain. The NordVPN servers are:

nameserver 78.46.223.24
nameserver 162.242.211.137 

If there are any more, delete them, and then make the resolv.conf file immutable with the following command:

sudo chattr +i /etc/resolv.conf 

Reboot. To reverse the process:

su
chattr -i /etc/resolv.conf
nano /etc/resolv.conf 

Enter preferred DNS servers and make file immutable again:

chattr +i /etc/resolv.conf

Restoring GRUB2 (Antergos)

Method One:

Boot Live CD and run the following command to determine where your Antergos/Arch/Manjaro partition is.

blkid

Mount it.

mount /dev/sda5 /mnt

Change root directory.

mount -t proc proc /mnt/pro

mount -t sysfs sys /mnt/sys

mount -o bind /dev /mnt/dev

mount -t devpts pts /mnt/dev/pts/

chroot /mnt Install mtools and os-prober.

pacman -S mtools os-prober

Install to dev/sda (or whichever your mbr is.)

grub-install /dev/sda

Update and configure GRUB

Method Two: 

pacman -S arch-install-scripts --noconfirm

No Screensaver in Gnome 3?

Problem: Screensaver although installed, doesn't seem to work. The issue appears to be that xscreensaver doesn't auto-start. (Check in 'System Monitor' to see whether this is the case.)

If it is, in home>.config>autostart create an empty text-file called  'xscreensaver.desktop' and paste in the following information and reboot (then check 'System Monitor' again):

[Desktop Entry]
Type=Application
Exec=/usr/bin/xscreensaver -nosplash
Hidden=false
X-GNOME-Autostart-enabled=true
Name=xscreensaver
Comment=Screensaver for xserver
Name[en_GB]=xscreensaver
