Notas de Lançamento do Linux Mint 18 Cinnamon

Linux Mint 18 “Sarah” Cinnamon Edition


Movendo janelas que não cabem na tela

Caso sua resolução de tela seka muito baixa, algumas janelas podem não caber na tela.

Enquanto pressiona a tecla ALT, você pode clicar e segurar em qualquer parte da janela, usando o mouse, e movê-la pela tela.

Instalando os codecs multimídia estando desconectado da internet

Para baixar os codecs de mídia em um arquivo instalável:

  • Inicie o Linux Mint ISO em um computador conectado à internet
  • Abra o terminal e digite “apt download mint-meta-codecs” (sem as aspas)
  • Isso criará o arquivo “mint-meta-codecs.tgz”

No computador sem acesso à Internet você pode descompactar esse arquivo e executar ./install.sh (ou “sudo dpkg -i *.deb”) para instalar os codecs mutimídia.

Booting with non-PAE CPUs

To boot Linux Mint 18 on CPU 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

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".
  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.

Note that during a “point upgrade” (for instance between Linux Mint 17.2 and 17.3), the kernel and hardware drivers are not impacted, so you get all the new features without risking regressions on

Important information

New backport component in repositories

In previous releases, Linux Mint repositories had 3 components enabled by default: main, upstream and import.

This was changed in Linux Mint 18:

The backport component is now also required and enabled by default.

If you're upgrading manually from a previous release, please make sure to add this component to your APT sources.

AMD Catalyst (fglrx) drivers

The AMD Catalyst (fglrx) drivers are not compatible with Xorg 1.18, which is the version used in Linux Mint 18.

These drivers are proprietary and so their code is not available. AMD indicated they no longer wanted to support them and urged their customers to use open-source drivers instead.

If you are using an ATI GPU in Linux Mint 18, the operating system will either select the Radeon or AMDGPU drivers for you, and these are installed by default.

UEFI support

UEFI is fully supported.

Linux Mint is not certified by Microsoft (and should not need to be). If your computer is using “secureBoot”, turn it off.

Note: If you really need secureBoot, you will need to use rEFInd and sign the kernel with a MOK.

Known issues

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.

LSB dependency issue with Epson drivers and Google Earth

A missing package prevents the installation of the Epson drivers and of Google Earth.

This is a known issue upstream in Ubuntu which should soon be addressed. You can follow the progress on this issue in this bug report.

Mouse cursor disappears with Intel GPU

The mouse cursor disappears after switching users or suspending the computer. This is a known issue. Click here to see the upstream bug report.

Freezes/Crashes with ASRock Skylake motherboards

A known issue is affecting ASRock Skylake motherboards. The kernel floods /var/log/syslog with messages until the disk runs out of space.

If you are suffering from this issue add “echo 'disable' > /sys/firmware/acpi/interrupts/gpe6F” into your /etc/rc.local (to edit this file with admin privileges, you can type “gksu xed /etc/rc.local”).

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

Other issues

Linux Mint 18 is based on Ubuntu 16.04. Make sure to read the Ubuntu release notes.
