Important links


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 ./ (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

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 hardware support.

Important information

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", you might need to turn it off.

Note: You can also check rEFInd and sign the kernel with a MOK.

Known issues

Grub fails to install grub-efi-amd64-signed

In EFI mode, if the installer fails with the following error message:

"The 'grub-efi-amd64-signed' package failed to install into /target/."

Reboot the live medium and disconnect the computer from the Internet before launching the installation.

The installation should then proceed in offline mode and prevent this issue from happening.

NVIDIA Optimus

On NVIDIA Optimus laptops the Driver Manager recommends the installation of the NVIDIA drivers.

These drivers add support for NVIDIA Prime, which gives you the ability to switch between the NVIDIA and the Intel chipset.

After you install these drivers, you need to reboot the computer for them to load.

Upon reboot, an issue is preventing NVIDIA prime from working correctly (you won't have 3D acceleration in your first session, and the NVIDIA prime system tray icon won't load).

Simply log out and log back in to fix this issue.

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

Force UEFI dialog hanging the installation

The following bug is affecting Linux Mint:

The issue occurs in EFI mode, when the HDD (or SSD) is new (without a partition table) and the installer is connected to the Internet.

To work around this problem, disable your Internet connection before launching the installer, or let the installer partition your drive automatically first (during a first install) and then install a second time with manual partitioning.
