Release Notes for Peppermint Six

  • Peppermint makes use of the Xfwm4 window manager and the LXDE desktop environment. This is unlike other Linux distributions that use LXDE as the default desktop environment as it is common to use the Openbox window manager. As a result, there are more window manager features, however some things within the window manager settings may not function as they were originally intended to in Xfce desktop environment, where Xfwm4 was originally intended to run.

  • The "Keyboard and Mouse", "Keyboard Layout", and "Keyboard Shortcuts" applications from previous versions of Peppermint has been removed. Input device settings have been added into the Peppermint Control Center located within the "Preferences" menu.

  • Software ratings with the Software Manger, 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 LLC, however we do encourage Peppermint users to submit feedback as we all benefit from this feedback.

  • There is an upstream bug with the default panel application, "lxpanel", that prevents the "Directory Menu" panel applet from functioning properly. This particular issue is unlikely to be fixed in the future as lxpanel development is presently halted in favor of LXQT development.

  • Peppermint Six is based on the Ubuntu 14.04.2 point release and makes use of its package repositories. As a result, any bugs that affect Ubuntu 14.04.2 may potentially affect Peppermint Six. 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.

  • Keyboard shortcut support in the Peppermint Control Center is not 100% complete and there are still several bugs that need to be worked through. Technically it works, but some strange behavior may occur if you attempt to use certain key combinations. Updates to the control center will be issued to address this. Manual editing of the configuration files may be necessary in some instances. The configuration files are located at ~/.config/peppermint-control-center/xbindkeys.conf and ~/.config/xfce4/xfconf/xfce-perchannel-xml/xfce4-keyboard-shortcuts.xml should you wish to edit them manually.

  • The Peppermint Control Center and the Ice application do not yet support languages other than US English. This will hopefully be addressed in the near future.

  • Electing to go straight to the installer when booting into the ISO file will result in some visual anomalies during the install process. This will appear in the form of overlapping windows. This issue has no functional effect on the installed system but can be rather annoying. As such, we recommend booting to a live session and running the installer.

  • The browsers Chromium and Chrome have recently moved to a new graphics engine called "Aura" that can cause some visual anomalies on the desktop when used in combination with certain hardware. Disabling hardware acceleration in the browsers settings usually mitigates or fixes the problem.

  • 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. If a fix for this surfaces, we'll issue a respin of the ISO with the fix as soon as possible.

  • The desktop pager on the panel has some visual glitches in that it doesn't refresh properly. This is an upstream issue with lxpanel and will not likely be fixed in the future. Clicking on the pager to change workspaces still works as normal.

  • The new dark theme 'Peppermix-Dark' may still contain a few minor graphic glitches, if you spot any we'd appreciate it if you'd report them on the forum so they can be fixed, and use of the Peppermix-Dark theme causes 2 x "Gtk-WARNING **: Theme parsing error" when sudo is used to elevate privileges in the terminal, these warnings are harmless and can be safely ignored.

  • Plugging in removable media does not cause the new Nemo file manager to prompt to mount the drive, you need to enter the file manager and click on the drive in the left hand column, it will then be mounted.

  • The new i3lock screenlock doesn't prompt for a password, this is a 'feature' not a glitch, but if you find yourself looking at screen with nothing but a digital clock in a circle you need to enter your password then hit enter to unlock the screen .. the screenlock is only ever activated manually or after the PC is resumed from sleep so you shouldn't arrive at it unexpectedly but we thought it best to mention it.

  • It has been reported that installing the TLP power manager from their PPA will cause a dependency problem with the utopic LTS enablement stack, our advice is to not use TLP (most of its functionality is now in the kernel), but if you choose to do so, please ask for advice on the forum.

Thank you for downloading and utilizing Peppermint.
