I used it for 3 weeks and it is quite good. But I had to install a lot of
software, including Open Office.
Mepis Antix is quite good and very fast. Of course, a little more
uncomfortable to use than Ubuntu.
I definitely recommend it.

There is a new member of the Ubuntu family. It uses LXDE and it is called
Lubuntu. Early reports make it the fastest Ubuntu yet, quite a bit faster
than Xubuntu.

https://wiki.ubuntu.com/Lubuntu

Anti-X login says that LXDE is available and Synaptic says it's
installed, but my system will not log into it. It also says that
Openbox is installed, but I can not log into it either. There is
another WM called FVWM Crystal which I'm currently logged into right
now. I just found it. I've never heard of it before, so I've got
some exploring to do. The more that I play with this little OS, the
more that I like it and the more that I think that Mepis should divert
all of it's efforts toward it's further development.

I would like all the window managers that it says it has to actually
work. So far it's WMs that I could get working are IceWM, Fluxbox,
FVWM Crystal and XFCE.

Update: I just got LXDE up and running, so I've even got more exploring to do.

I used LXDE a lot under Ubuntu and I like it but not very much. I miss the
multiple desktops. It has only two and when I add some more the new
configuration is not saved and have to add more desktops next time. But it is
very fast and responsive. But it is more uncomfortable to use than GNOME. I also
use FVWM-Crystal sometimes but I am too lazy to use the menus. I just left-click
on the desktop to start the terminal and start applications from there. And it
is really more comfortable than LXDE.
Under Antix it seems that LXDE does not work either. I installed GNOME, KDE
and XFCE and it seemed to have managed, but at startup I never managed to use
anything than the default windowmanager, it seems that it is JWM. Then it was
easy to switch to Fluxbox.
Under Antix it was quite easy to install programs from the command line, I had
to become root by using the su command and root password and then everything was
easy with

aptitude install whatever.

Among others I installed OpenOffice and had to install Digikam, as I could not
get F-spot to work.
Now I am writing under Crunchbang Linux.

Using F1 to choose your WM at the log in screen will show you WM
options that you do not yet have. It seems that the OS's standard
package manager, Meta Installer, does not bring in the entire WM.

In Fluxbox open the menu and go to; (Full
Fluxbox>Applications>System>Package Management>Synaptic) and you can
bring in LXDE and or FVWM Crystal from there.

Synaptic will not allow you to bring in Gnome or KDE. I do not know
why those are offered as WM options at the log in screen.

GQview is available as a photo viewer. It is much less of a pain in
the butt and uses less system resources than F-Spot or DigiKam.

Under Antix I installed Mirage and gpicview, as they were easier to use.
GQView, by default, shows the high resolution pictures as huge, does not fit
them to window.
I had to have digikam for importing photos.

Mirage is quite good

aptitude install mirage

If i remember well, I also used gwenview under Antix.
By the way, it is a good idea to go back and install Antix. I will experiment
with it some more. I will install it back right now.
I liked Antix's DVD burner, Gnomebaker very much but I preferred to install
and use Brasero.
