Known problems in Linux Mint Debian
No boot splash
Plymouth wasn't considered stable enough to be included in LMDE. Alternatives such as usplash or splashy seemed obsolete and rather than using them temporarily, it was decided not to use any default boot splash.
Print to PDF
The PDF printer produces blank PDF documents. To work around this problem, launch the "Printing" tool from the menu, remove the PDF printer and add a new one.
Grub
LMDE uses the same version of Grub as Debian Testing. This version describes LMDE as "LinuxMint" instead of "Linux Mint Debian" as defined in /etc/linuxmint/info.
Software Sources
The Software Sources tool isn't branded yet. It contains two tabs ("Update" and "Statistics") which are not relevant to LMDE.
Missing packages
The following packages are missing and will soon be ported to LMDE: jockey-gtk, usb-creator, simple-ccsm.
Upstream issues
LMDE is based on Debian Testing. Make sure to read the known issues related to it.
