KDE The KDE team has released KDE 4.3. This release comes packed with improvements and bug fixes - in fact, over the last six months, 10000 bugs were squashed, 2000 feature requests handled, and 63000 changes were checked in by 700 people. We've already talked about this new release in quite some detail last week, but let's take a look at the most important new features anyway.

Basically, use an Intel chipset and your distro's drivers or an nVidia chipset with a recent driver. Your mileage might vary with ATI, but you'll be hopping around with the ati, radeonhd and fglrx drivers and stuff like Xv will still be broken or working poorly.


I *am* using an NVIDIA card (6200, 128MB dedicated RAM) with a recent driver, and KDE 4 is STILL showing BAD performance. Resizing especially is unusable, and various other animations are jittery.

The exact same card with the exact same driver has NO problems with Compiz - which is smooth as butter.

Can't explain that then. I have a 7300GT (mainly because I knew that it still supported XvMC) and that works pretty well. The 9500GT didn't work well but does with the latest drivers. Mind you, I suppose when you're using binary drivers and different combinations of chipsets then mileage varies. The fact is that they will have a tendency to fix things in the most recent chipsets first. I've still seen some strange issues with Compiz, mostly related to resizing. It still seems as though nVidia falls back to software rendering on some chipsets for certain things.

The Intel stuff seems to work better than anything else and works pretty well across the board for Compiz and KDE 4, apart from that known cock up that Ubuntu inherited in their recent release that slows everything down.

It's a complex area, but the common theme is they're graphics issues regardless of whether some things work OK in Compiz or vice versa.

Fair enough.

The only thing to note other than that reasonable summary is that the situation is improving daily:

... in all parts of the Linux graphics stack.

The releases of distributions due out later this year will hopefully have many of the issues of the graphics stack all sorted.

Coincidentally, and happily, these releases of major Linux distributions will be the first to include KDE 4.3.

What driver version are you using? From what I could gather (and mind you, I haven't reached KDE4 performance zen yet), not all generations of the nVidia driver have been fixed, and the oldest ones might even be doomed to never get officially fixed I'm afraid.

I'm using an old GeForce FX 5700 here (not the most up-to-date hardware out there, but should be more than enough for running KDE4) with the 173.14.18 drivers (I think nothing above it really supports my card). Seems like there's a new revision of this driver and I might try it soon, but so far performance is pretty choppy.

Anyway, some time ago I decided to give the nouveau drivers a go (http://nouveau.freedesktop.org) since I was getting desperate about the bad performance of KDE4. Much to my surprise the 2D performance was *greatly* improved (resizing and scrolling suddenly became really smooth), but at the expense of completely dropping 3D acceleration and some 2D features (like being able to view webcam streams in Skype, for some reason). I can live without 3D acceleration (it's been ages since I've played any games), but Skype video is a must, so I had to go back to the closed-source drivers, but I'll keep an eye on the open-source one, seems like they are doing things right.

What driver version are you using?

You see, Thom, if you are using Nvidia and driver version 1008 with Kernel 2.6.29 with Xorg 7.2.1.3 then you might get good 3D effects with KDE 4.2.99.5. But that combination gives really dicey 2D. So you might be better off with Radeon. But only of you have something between an HD2400 and an HD2475. (But not the HD2450, because that will give you a black screen after the KDE4 splash is done.) If you decide on that, you'll need to compile an Xorg nightly that's after July 27. (And you'll have to use a development kernel to get 3D support. The DRM changed.) Make sure and use the final 4.3 release for that, because there was a patch that went in right before to keep KDE from frying your LCD on monitors that don't follow spec properly.

Intel X3300 was working pretty well last week with Xorg 7.1.2.3 and driver version 6666 with kernel 2.6.30 (but not 2.6.29). But then something changed after I rebooted and everything locks up if you try to scroll any text, and I'm still trying to track down what it was. I'll let you know if I find out.

Lemur says that he has two Nvidias that really fly with KDE4.3, but also says that Nvidia cards perform very poorly with KDE 4.3 because the driver is proprietary and so doesn't support Xrender. He also says that he has no idea what hardware or software to recommend, except that you should definitely use KDE4, because it rocks.

I wish I could give you more definite advice. Especially as KDE4 is really worth using these days as it has matured into such a rock solid desktop platform.

For now, you may want to run XFce, or LXDE, or Gnome, which should all work well with whatever software and hardware you have now. But be advised that they are not nearly as Innovative. So if you use them, you're probably destroying the future of Linux graphics.

HTH,
Steve

No clue there as to why - my only problem is resizing (I wouldn't call it unusable though). No jittery animations here (except when I connect my 40" LCD TV ;)
