Re: RFC/Discuss: Replace KDE by LXDE on LTSP?

Thanks for your input Andrew, correcting what I didn't get :)

That's right. 

But you get into the same memory issues regarding libraries which the 
benchmark outlines above, even if LXDE may be flight light in itself ... 
This because of library towering issues at hand. Sorry for pointing that 
out, but my cynical engineering side was revealed :)

Secondly choices done in Debian for end user experience are not always the 
best ones. Just a glimpse on what's done with OpenSuSE, Mandriva, Xandros 
and Ubuntu, you may see that others does a considerable better job 
providing desktops for end users compared with Debian. Even if Debian has 
improved immensely the last 4-5 years. 

That said, I know that such a statement commits. The good news is that 
desktop improvements usually made by distribution tailoring, are going 
into the desktop system itself. Usually the different Linux distroes are 
tailoring, plumbing and tweaking to get a really good desktop in place. 

Now much of this work are done within the different desktop environments 
itself, making everything blend nicely, and using common infrastructure as 
D-bus, x.org, HAL etc. Things that make you copy and past with ease 
between Gnome and KDE applications. 

E.g the educational experience from the MEDUSA project with 325.000 pupils 
and teachers in Canary Island who uses a Kubuntu based school desktop, are 
now tailored to be a standard part of KDE4 (finally): 


Here is the roadmap and background for including experiences for education 
onto the desktop:

Such ideas may be useful for LXDE developers too?

What's good news, is the race on improving Linux speed started by the 
interest for Mobile Internet Devices and Netbooks. Previously most free 
software developers ware focusing on catch up, getting the Linux desktop 
to be a real competitor to Mac and Windows, having having comparable 
functions and features.  This goal was reached 3-4 years ago IMHO. 

This desktop catch up lead to memory eating beast as OpenOffice and Firefox, 
not focusing on memory usage. 

With Netbooks and phones we are in a kind of reversed Mores Law situation. 
Meaning that Netbooks are sold in an extremely price sensitive market, and 
phones even more. Then it might be more sense to reduce memory and cpu 
power a little to get enough battery power to run a bigger screen, or more 
hours working desktop before a recharge. When big manufacturers can cut of 
10 USD to a 250 USD machine in production cost, it worth while the added 
cost of making improving the software - making it run smooth even with 
reduced computer power, getting longer battery life, bigger screen and 
mobile network which are up all the time. 

The race is on, focusing on memory footprint, running more software with 
less clock cycles, speed, ease of use and bling. We are already seeing 
great innovation ahead caused by speedy Web runtime (fast JavaScript 
engines) and effects on getting Linux on mobile devices.  You've probably 
heard about the JavaScript web browser runtime race[3], Sugar Desktop 
Environment, KDE4 with built in bling, reduced power etc.

This is all examples on the mega trend we are in. More focus on user 
experience for different users, bling and speed -- with less cpu, smaller 
screens, longer batterylife and mobile Internet. 

It's just a matter of time before this innovations flushes into the Debian 
repositories, being ready for stable use with the next release, 20 months 
from now or so :)
