Ok thanks. That was useful.
I note the nVidia driver and your 8400M GS detected by the 275.21 nVidia proprietary driver:
1007.591] Build Operating System: openSUSE SUSE LINUX 1007.591] Current Operating System: Linux linux-4xk6.site 18.104.22.168-0.7-desktop #1 SMP PREEMPT 2011-07-21 02:17:24 +0200 i686 .......... 1007.646] (II) NVIDIA GLX Module **275.21 ** Mon Jul 18 14:55:52 PDT 2011 .......... 1007.658] (II) NVIDIA dlloader X Driver ** 275.21** Mon Jul 18 14:38:30 PDT 2011 .......... 1007.710] (II) NVIDIA(0): NVIDIA GPU GeForce 8400M GS (G86M) at PCI:1:0:0 (GPU-0)
When I look at the nVidia site I note:
Current NVIDIA Linux graphics driver releases - nV News Forums
- Current long-lived branch release: 275.28 (x86 / x86_64)
- Current official release: 280.13 (x86 / x86_64)
- Current prerelease: 285.05.09
so the driver that is in use currently is the 280.13. Your 275.21 is none of those. Possibly a newer driver would be better ?
You could also install ‘nvidia-settings’ control as packaged by Packman Packagers : PackMan :: Informationen zum Paket nvidia-settings and use that to tune your nVidia hardware.
In addition I recall one forum thread here: nouveau & screen blanking where they complained of poor nVidia driver video performance and proposed a solution in same thread.
Have you blacklisted the ‘nouveau’ driver ? Have you put NO_KMS_IN_INITRD to yes in YaST > System > etc/sysconfig Editor > system > kernel ? Many of us find that ESSENTIAL for the nvidia proprietary graphic driver to work properly.
