1.Locked root account
The root account is now locked by default.
To use the recovery console (from the Grub menu) or log in as root, you first need to give root a new password:
sudo passwd root
2.Virtualbox Guest Additions
To add support for shared folders, drag and drop, proper acceleration and display resolution in Virtualbox, click on the "Devices" menu of Virtualbox and choose "Insert Guest Additions CD Image". Choose "download" when asked and follow the instructions.
For more info, read Installing the VirtualBox Guest Additions.
3.Sound and microphone issues
If you're facing issues with your microphone or your sound output, please install "pavucontrol".
This will add "PulseAudio Volume Control" to your menu. This application has more configuration options than the default volume control.
4.DVD Playback with VLC
If VLC does not find your DVD player, click on Media->Open Disc, and specify '/dev/sr0' as the disc device.
5.Issues with KDE apps
If you're experiencing issues with KDE apps (Okular, Gwenview, KStars..etc) run the following command:
apt install kdelibs-bin kdelibs5-data kdelibs5-plugins
LMDE 3 is based on Debian Stretch
8.Username and password in the live session
In the live session, the username is "mint" and the password is empty (i.e. just press Enter if asked for a password).
9.Moving windows which don't fit in the screen
If your screen resolution is too low, some windows might not fit in the screen.
While pressing the ALT key, you can grab any part of a window with the mouse and move it across the screen.
10.Installing multimedia codecs offline
To download the multimedia codecs into an installable archive:
Boot from the Linux Mint ISO on a computer which is connected to the Internet
Open a terminal and type "apt download mint-meta-codecs" (without the quotes)
This creates a "mint-meta-codecs.tgz" archive
On computers which do not have an Internet access, you can decompress this archive and run ./install.sh (or alternatively "sudo dpkg -i *.deb") to install the multimedia codecs.
11.Booting with non-PAE CPUs
To boot Linux Mint on CPUs which do not officially support PAE (Pentium M processors for instance), please use the "Start Linux Mint with PAE forced" option from the boot menu.
