[177.70] Problems again with latest KDE and xorg
1) I am having again serious performance problems which makes my desktop unusable. My configuration:

- Driver 177.70 with Geoforce 8400M GS (OpenSuse Factory) (all recomended performance options applied)
- Kde 4.1.64 (latest trunk). I think we are about to release KDE 4.1.1 in a few days, so I presume you will get some bad press again nivida.
- xorg-x11 7.3 (opensuse build 168.4)
- xorg-x11-server 7.3 (opensuse build 155.5)

I have to say that during KDE 4.1.63 and Nvidia 177.70 everything improved a lot (but not to the point to say that performance was good). But now my desktop is unusable again.

2) The bad performance of NVidia makes my laptop (dell xps m1330) die due to temperature even with patched bios (A12). I presume this is due to:
- the inherent temperature problems of nvidia defective GPU (not related only to Linux systems)
- the defective Nvidia drivers on Linux, which makes the CPU do tasks related to the graphic card

I am very dissapointed with NVidia. Even if performance and temperature problems are corrected, I will NEVER buy a system again without decent Open Source drivers. At the moment I think only Intel is supporting Open Source at that level.

Did you compile KDE trunk from source?
I use KDE 4.1.1 from opensuse Factory repo with 177.70 and have no such problems.

Have you tried with shipped xorg, the one from factory repo is experimental and caused problems for me.

I have a 8400GS on laptop HP dv6624, openSuSE 11.0 with default xorg and nvidia 177.70 with default installation settings + OnDemandVBlankInterrupts=true.

All works fine ! with KDE4.1 from factory repo

How did you manage to install 177.70? Manually or is there a repository with beta drivers?

Manually - you need gcc and kernel-source.

I also did it manually but the installer claimed wrong kernel source till I compiled kernel of it (without installing compilation results) and later the X server initialization take so long to start so KDM gave up waiting.
The only way was to start sesion with 'startx' command.

I wish there was also dev repository to keep people updated if they want.

did you use your distros kernel source packages or the vanilla kernel?

Re: [177.70] Problems again with latest KDE and xorg
I use distro kernel 2.6.25 and had to compile the source in order to install 177.70.

When I install driver with 2.6.27 there was no problem with compilation but after loging out from KDE session (or any other) the wait for KDM is so long that easier is to reboot computer than restart the session.
Is it common for everyone? (I use Quadro FX 570M and openSUSE 11.1A2 - Factory brand)
