Release Notes for Peppermint Nine

  • Peppermint Nine makes use of the Xfwm4 window manager, and Xfce bottom panel in the LXDE desktop environment. This is unlike other Linux distributions that use LXDE as the default desktop environment where it is common to use the Openbox window manager, and lxpanel. As a result, there are more window manager features, however some things within the window manager settings and some Xfce panel plugins may not function 100% as intended to in their native Xfce desktop environment.

  • Software ratings within the Software Manager (mintinstall) are based on feedback submitted by users to the website This website is part of the Linux Mint project and is not affiliated with Peppermint or Peppermint OS, however we do encourage Peppermint users to submit feedback as we all benefit from this feedback.

  • Peppermint Nine is built on the Ubuntu 18.04 LTS code base and makes use of its package repositories. As a result, any bugs that affect Ubuntu 18.04 may potentially affect Peppermint Nine. Please report bugs for Ubuntu's packages to the necessary bug trackers and please report bugs for Peppermint specific packages to Peppermint's bug tracker.

  • The Peppermint Settings Panel, Peppermint Control Center, and Ubiquity installation slideshow do not yet support languages other than US English. This will hopefully be addressed in the future.

  • Electing to go straight to the installer or OEM install option when booting into the ISO file may result in a very minor visual anomaly where the background image doesn’t always display. This issue has no functional effect on the installed system.

  • Certain peripherals manufactured by Logitech can cause an additional battery icon to appear on the panel when they're connected. This is due to the system reading their batteries. This has no negative affects on the function of the system.

  • Electing to encrypt your home folder during the installation process results in the system not presenting a mount key upon first boot. Running the command ecryptfs-unwrap-passphrase and entering your system password will result in the presentation of the key.

  • Whilst the 64bit version of Peppermint 9 supports both UEFI and Secureboot, electing to install 3rd party software that doesn’t contain a valid key during the install may fail with Secureboot enabled. We advise you either disable Secureboot during the installation or do not choose to install 3rd party software during the installation.

  • The USB Stick Formatter utility on some hardware may appear to format the stick but has not, running it for a second or third time has proven successful during testing, or you can use the 'Disks' utility for formatting.

  • Firefox is known to have issues with dark gtk themes and some websites, such as the Youtube search box displaying white text on a white background and therefore being unreadable, we've included a fix for this that locks Firefox to the Peppermint-Red-Mix theme .. if you want to unlock/lock the Firefox theme you'll find the 'Firefox Theme Lock' application either in the menu or in the new Peppermint Settings Panel, unlocking the Firefox theme will result in Firefox using the current system wide gtk theme. There is also a "Thunderbird Theme Lock" in the Peppermint Settings Panel for the same reason.

  • The Numix Folders utility may not always work properly in a "Live" environment.

  • Keeping a home folder from a previous version will result in missing configuration files because they cannot be copied from /etc/skel during the account setup stage, so it is advisable to only do a full clean install of Peppermint 9, or (where keeping a /home partition from a previous version) to create a new user account with a different name than any currently held accounts. (you can then copy any user files such as docs/pics/music/etc. across to the new account)
Thank you for downloading Peppermint, we hope you enjoy using it as much as we did creating it.
