That is if enlightenment can make it real, real easy:-) Wed, 16 Feb 2011 00:11:00 GMT donotreply@osnews.com (fran) Comments Questionable statement http://www.osnews.com/thread?462664 http://www.osnews.com/thread?462664 The beauty of this comes from the fact that EFL does NOT need hardware accellerated support! Although it will take advantage of it (if found) it is not a strict requirement.

Do GTK+ and Qt require hardware acceleration?

The reason for this is the EFL canvas (named Evas) is a lot smarter that your average QT or GTK+ canvas. Instead of blindly rendering pixels and then forgetting about them, it actually keeps track of what is shown at the screen at any given time. Then it can calculated only the parts that have changed and do not render the rest.

Don't GTK+ and Qt also support XDAMAGE?

Perhaps the difference is:

The programmer is also completely un-aware of this.

More elaboration is in order on how EFL is unique.

Well if you are developing native applications for your 8-core machine with infinite memory then EFL might not seem something important to you. If however you are into embedded devices (think 8-16 MBs of RAM and simple processors) then EFL might be the best thing since sliced bread. It all comes down to speed. EFL are truly optimized for speed!


Define "speed".

We've tried running E17 (via Arch Linux I believe) on our diskless machines (about a month ago), and while things are smooth, it's not speedy. And it comes at a *very* heavy price, using up most of the 1 GB of RAM and 90% CPU with just the desktop loaded with an animated wallpaper.

Disabling the animated wallpaper drops CPU usage a bit, but it's still over 80% when moving windows around or switching windows.

It sure looks pretty, though, with smooth animations and no tearing or anything like that. But it's definitely not "speedy", nor efficient.

This is on a 2.0 GHz AMD Sempron CPU with nVidia 6100 graphics onboard, and the binary nvidia driver.

GNOME 2.x, KDE 3.x, and even KDE 4.x are more efficient (10-20% CPU, 100-200 MB RAM) and nicer to use, on the same hardware. (One of the nice things about diskless clients is that switching OSes is a simple reboot away.)

That was a deal killer for me (still as of 6 months ago), especially with some graphics intense applications which don't have a friendly resize behavior.

That's with the default theme (it has some system monitors), chromium and an xterm running. This is one a 5+ year old laptop at 1.3 ghz with crummy Intel 855GM video.
So yeah, I'd say it's pretty damn smooth and speedy. Although it would be nice if the default theme wasnt so washed out with white that you can't see anything of it.Edited 2011-02-16 04:09 UTC Wed, 16 Feb 2011 04:08:00 GMT donotreply@osnews.com (Soulbender) Comments RE: E17 anything but "speedy" http://www.osnews.com/thread?462682 http://www.osnews.com/thread?462682 Ill preface I appreciate the arch devs for packaging pre release software. Generally my experience with packaged e17 & efl has been shaky at best. For arch using repo package my cpu usage was relativley high to me 20-30, with composite more like 40-60%. Compiled I rarely go above 10%, including compositing. I don't know what it is, but self compiling just worked better. I used easy_e17 for a while and switched to my own package builds later. Archs package were pretty bare of configuration flags, however i think a lot of options are auto enabled. So I don't know where the problem is.

None the less I'm happy to hear this I've been an e17 user since 2005, prior to that an e16 user. I have had great experiences with e17.

I've ran e17 on much slower hardware without any hitches are you running KDE4/Gnome applications in tandem with e17 thats probably the problem... you get all the bloat of Gnome + QT4 + e17 which makes it look bad and it really isn't Wed, 16 Feb 2011 04:43:00 GMT donotreply@osnews.com (cb88) Comments Unstable http://www.osnews.com/thread?462685 http://www.osnews.com/thread?462685 My problem with E17 has been its very unstable configuration. I play around in the settings and then it randomly begins to segfault. And it will segfault on boot every single time. My only chance is then to reset the configuration and start all over. That's why I can't use it on my laptop although I sure would like to.

rasterman has been said to be an awesome programmer doing wonders but I don't think any post gdi32 graphic toolkit used today lacks damage/dirty information (gdi32 has at least some form of it). Java Swing has it, irrc I used an option in kde4 to monitor the redraw regions .. Any experienced dev can confirm that ?

Do GTK+ and Qt require hardware acceleration?
No, except if you want some effects (3D/fast scrolling/physics). EFL provides those effects without hardware acceleration.

Mobile devices ship more and more with powerful GPUs, anyway, nowadays; it is just more efficient. But if you just can't have a (good) GPU, EFL offers a way to still get what you want.

It's very fast and very pretty. The problem I had with it was the stability. They sort that and I'll switch to it full time on the craptop, maybe even on the desktop. Much better looking that LXDE. (It could also do with a better file manager.) It does make you realise just how fat things have become, it's obscene how slow some things are on computers from even only a few years ago. Seams like you need to keep getting a faster computer just to stay still as things get fatter. Enlightenment goes against this trend, and that makes it a breath of fresh air.
