To be pedantic the "last" command isn't recording anything. It is only reporting what has already been recorded. > > Today, I'm checking my logs, and I don't see any record of logins > > to the desktop unless the user also started a shell in a virtual > > terminal. That would be due to your xdm, gdm, gdm3, lightdm, kdm or other graphical login manager. It is responsible for recording desktop logins. Some do. Some do not. If they don't then I think that is a bug. But people who know about last and logins are becoming fewer every day and so this part of the system has atrophied. > > Has this changed recently?

What graphical login manager are you using? As I recall lightdm for example does not record this information. I am pretty sure I saw that there was a bug report on it. Ah... Here it is: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=648604 What terminal emulator are you using? Xterm records this information. But I assume that like the desktop managers that some terminal emulators have fallen out of recording it. Plus many people today log into a system and never start a terminal emulator, doing everything they want to do through other graphical applications. If a user only starts a web browser, file manager, office applications, then there won't be any terminal emulators started. > Is there a command that does?

If you want this functionality then I suggest trying a different login manager until a fixed version of lightdm appears. I do like lightdm. You could look to see if there is a backport to Stable. Bob
