unable to launch "/usr/bin/lxsession..."

[Jordan_Schleif]

Hi there,

After logging into Lubuntu, I get this message before the desktop appears:


unable to launch "/usr/bin/lxsession -s Lubuntu -e LXDE" X session --- "/usr/bin/lxsession -s Lubuntu -e LXDE" not found; falling back to default session.

The desktop loads normally after that, and everything seems to work fine, but it's annoying to have to click to dismiss this message every login.

I've done some searching and have come across similar issues, some involve reinstalling the environment, e.g. xfce4. But I don't know the equivalent command for Lubuntu.

Does anyone know what might be going on here?

Hello and welcome to the forums

Can you have a look in the the /usr/share/xsessions directory and report back its contents - e.g. open a terminal and use



ls /usr/share/xsessions


Also, can you clarify whether the message says usr/bin/lxsession or /usr/bin/lxsession?

Yeah, that was a typo, it is "/usr/bin/lxsession".

Here is what I have in that directory. "Lubuntu.desktop" is the session I attempt to use upon login.

Lubuntu.desktop Lubuntu-Netbook.desktop openbox.desktop

Here is the contents of Lubuntu.desktop:

/usr/bin/lxsession was missing.


sudo apt-get install --reinstall lxsession

helped me to log back in and start Lubuntu.
