Release Notes for Linux Mint 19 MATE
This is Linux Mint 19, codename Tara.
Swap with home directory encryption
There is an issue with home directory encryption that causes swap to be misconfigured during installation. To correct this, run the following two commands after logging in to your new Linux Mint 19 installation:
sudo sed -i 's#/target##' /etc/crypttab
sudo sed -i '#^/swapfile#d' /etc/fstab
Follow it up with this command:
sudo update-initramfs -u
For more details see [FIX] no swap on fresh LM19 install with home directory encryption.
The default touchpad driver in this edition is "libinput" (provided by the xserver-xorg-input-libinput package).
If you experience problems with it, you can switch to another driver called "synaptics" (provided by the xserver-xorg-input-synaptics package).
To know which driver is used by your input devices, run the following command:
grep -i "Using input driver" /var/log/Xorg.0.log
When both drivers are installed, "synaptics" takes priority.
To switch to the "synaptics" driver, install it with the command:
apt install xserver-xorg-input-synaptics
Then log out and log back in.
To go back to using "libinput", simply remove the "synaptics" driver:
apt remove xserver-xorg-input-synaptics
Then log out and log back in.
Note: You can also try installing the "evdev" driver (provided by the xserver-xorg-input-evdev).
Garbled screen in Virtualbox
If the screen is garbled when launching Linux Mint in Virtualbox, switch to console with HOST+F1 (e.g. the RIGHT Ctrl key, no ALT) and back to tty7 with HOST+F7.
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.
Home directory encryption
Benchmarks have demonstrated that, in most cases, home directory encryption is slower than full disk encryption.
The move to systemd caused a regression in ecrypts which is responsible for mounting/unmounting encrypted home directories when you login and logout. Because of this issue, please be aware that in Mint 19 and newer releases, your encrypted home directory is no longer unmounted on logout: https://bugs.launchpad.net/ubuntu/+source/gnome-session/+bug/1734541.
The move to systemd caused a regression affecting LightDM guest sessions. Please be aware that in Mint 19 and newer releases, guest session processes are no longer properly confined: https://bugs.launchpad.net/ubuntu/+source/lightdm/+bug/1663157.
You can still enable guest sessions in the "Login Window" utility, but this option is now disabled by default.
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.
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.
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
Linux Mint 19 is based on Ubuntu 18.04. Make sure to read the Ubuntu release notes.
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).
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.
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.
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.
Solving freezes during the boot sequence
Some graphics cards don't work well with the open-source driver present in Linux Mint.
If Linux Mint freezes during boot time, use the "nomodeset" boot option as illustrated in the video below:
If you're booting in EFI mode, the procedure is similar but the menu looks slightly different:
Thanks to "nomodeset" you should be able to boot Linux Mint and install it on your computer.
After the installation, reboot the computer and hold SHIFT to force the boot menu to appear.
Add the "nomodeset" option as illustrated below:
If your graphics card is from NVIDIA, once in Linux Mint, perform the following steps to install the NVIDIA drivers:
- Run the Driver Manager
- Choose the NVIDIA drivers and wait for them to be installed
- Reboot the computer
With these drivers the system should now be stable and you no longer need to use "nomodeset".
Note: If you're using an Optimus card, you've nothing more to do. Upon reboot, a system tray icon should show up indicating which GPU is currently active. Click on it to switch GPUs.
Note: If you still cannot boot try one of the following solutions:
- Try with "nouveau.noaccel=1" instead of "nomodeset".
- Try with "noapic noacpi nosplash irqpoll" instead of "quiet splash".
- Use the "Compatibility mode" to boot and install Linux Mint.
- After the installation, use "Advanced Options" -> "Recovery mode" from the boot menu and choose "resume".
Choosing the right version of Linux Mint
Each new version comes with a new kernel and a newer set of drivers. Most of the time, this means newer versions are compatible with a larger variety of hardware components, but sometimes it might also introduce regressions. If you are facing hardware issues with the latest version of Linux Mint and you are unable to solve them, you can always try an earlier release. If that one works better for you, you can stick to it, or you can use it to install Linux Mint and then upgrade to the newer release.
