Novell and Ximian LinuxEdge has posted the videos of the presentation of Novell Desktop Linux 10 by Nat Friedman. "A preview of Novell Linux Desktop 10 was shown to an audience at the Solutions Linux conference this week. We have a selection of videos which display a variety of amazing effects through the use of XGL, including transparency, wobbling windows, a 3D cube for desktop switching, and a task switcher which displays a preview of windows."

Personally, I don't care about the wobbly windows, or any of the other "eye candy" effects. But what did impress me about the video was how smooth and responsive everything seemed to be.

I've been using Linux and FreeBSD with Xorg (previously XFree86) for years, and one thing that has bothered me for a long time is how relatively sluggish the X Window System feels compared to MS Windows. (And compared to YellowTab Zeta.)

It was my understanding that MS Windows achieves a more responsive GUI (lower latency) than X does due to graphical integration at the kernel level. But whatever the case, I'm really hurting for a more responsive Desktop these days. Hopefully XGL, or Cairo, or Glitz, or a combination of all these things that I've been reading about for so long now are the answer. And hopefully they are implemented into packages and distributions soon.

Yeah ... it's spelled enhancement, I know. What happened to the edit option?

"What happened to the edit option?"

Last time I checked it was only available for 20 minutes after the post was made.

I don't know what distro you're using, or what graphics card for that matter, but you might want to try Suse. Its "experimental" ATI OpenGL rendering (an option in Sax2, the X configuration frontend) did wonders for my X rendering responsiveness, where distros like Xandros and Linspire had failed horribly, and even Ubuntu wasn't quite as fast. I think it's got good nVidia drivers built in, too.

I've been using Gentoo for the last 18 months. (On my main machine anyway. I run FreeBSD / Ubuntu / Debian / Other distro / Other OS on my spare machine.)

I have an NVidia GeForce 6600 GT. 1GB of RAM running in Dual Channel mode. (512MB x 2) AMD XP3200+ CPU. Asus motherboard.

It seems to primarily be an issue with what I have come to call "redraw". (I don't know if that is the technically correct terminology or not though.) But for example, if you drag a window around in front of FireFox, it trails really bad. And just moving/resizing windows in general ... there's this definite feeling of lag/latency as you see the window frame being redrawn, or you see the icons being slowly repainted on the screen.

My nvidia card dirvers load at kernel level when loading RHEL 4.2 AS; and It's super fast and responsive; try it and you will know what I mean. But remember you will need nvidia based card and nvidia drivers not the out of the box drivers.
If you want to feel the difference before and after fire the screensave with one of its OpenGL and tick the check mark which says show frame rate, then hit preview.
In my case atlantis jumped from 5fps to 35 fps

That is just agpart driver modification if I'm not wrong, all other drivers have same feature.

Second, screensaver performance diff was because without proprietary drivers you were using xorg driver, which is 2d only. Atlantis was running on cpu.
