When I went back to gentoo, I decided to go with KDE/trunk, and 4.2 really is shaping up to something really nice. I understand that 4.2 is now branched off in svn, so trunk is now what will be 4.3. And it works great. I also gambled a bit and built it against qt-4.5 which seems really stable. What I miss in KDE now is a global ‘OS X’ like menu to save me some screen real estate, and a ‘OS X’/awn like dock…

I hope that qt-4.5 final and KDE 4.2 and future brings more performance increases, it’s soon completly smooth on my Quadro FX 570m …

And while I’m thinking about qt, give Nokia a round of applause for releasing qt under LGPL!

KDE4.1 update

August 26, 2008

Having used KDE4.1 for some time now I’ve grown accustomed to the changes and found some fixes to performance problems.

After reading this link and a recompile of qt-4.4 and all of KDE4.1 kwin no more uses ~80% cpu for no apparent reason. It does hower still use a hefty amount when dragging windows around…

After updating to nVidia’s latest beta drivers (177.67), things are now starting to work smoothly. I can now resize a window and not have to wait 10 seconds to see the results. So even nVidia are improving, thats nice. It’s just a shame the put themselfs in this position at all.

One thing with KDE4.1 I really don’t like is Kontact. It segfaults daily, and for no apparent reason. Since I built it without debugging symbols I can’t provide any useful backtraces, sorry. I also don’t like the changes in akregator: I dont want have a separate column for unread, just put that number right next to the feed name as in akregator in KDE3.5 please.

I also think that 4.1 uses to much screen area. I’d like the ‘Toolbar from current window’ at the top of the screen ( OS X lookalike ) but with the ability to add systray to it. That would enable me to get rid of the panel altogether and hence minimizing used screen area.

PC-BSD

August 15, 2008

So today I installed an alpha version of PC-BSD, which is based on FreeBSD 7. It was a really easy to use installer which allowed for zfs based file systems. It also includes KDE4.1. I must say that KDE4.1 is much smoother on *BSD than on linux. What the **** are nVidia doing with their drivers?

It seems however that PC-BSD didn’t like the disk i installed it on ( a usb attached 120 gb ata disk) and spits out lots of “SCSI error…”

Maybe I’ll wipe my OpenSolaris install of my internal HDD and install FreeBSD there instead as I need to learn a bit about it for future possible jobs. I’ll then install OpenSolaris on the USB drive and see if it fares better.

KDE4.1

August 10, 2008

I finally decided to switch to KDE4.1 for my every day use as DE on linux. The compilation and installation went smooth, but there are some outstanding performance problems with the nvidia drivers 😦

Transparency, wobbly windows and scrolling works ok. Resizing windows and switiching virtual desktops takes somewhere between 0.5 to 2 seconds. Something is very broken in the graphics stack on linux/X11/nVidia setups, and as far as I understand it, most of the blame lies with nVidia’s drivers.

I get a rather high cpu usage from kwin (about 30% on core) and i get significantly lower ‘score’ in glxgears. I get around ~3500 fps vs ~5000 fps on kde3.5.

Would be interesting to see how kde4.1 performs on OpenSolaris or FreeBSD with nvidia graphics.

I generally like kde4, so I can live with the delays from bad drivers, and I’m excited about all the new ideas kde4 brings to the table.
