opensuse 12.1 hardware requirements

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 #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

Which has:

  • 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.

… and finally, don’t forget this reminder to run ‘top’ in a terminal window and keep it running to see what process is taking up the CPU when you observe the slow behaviour…

Also, a caution here re: nvidia-settings.BEFORE you change any setting, take a screen dump of the window and save it as a default setting. That way you can restore things afterward to the original default, if need be (in case one can not remember the original setting).

Note I’ll be away on business and not back to either late Thursday or sometime Friday and not likely to have much in the way of Internet access. So good luck in your efforts.

when i installed nvidia graphic driver instead of nouveo, my laptop doesnot Sleep, Restart, Shutdown,… with kickoff bottons. when i select one of these keys after a while a black screen appear and laptop freezes. so i force to use one of the following methods for example shutdowning the laptop: 1- holding power key for 5 min or 2- using “init 0” command in terminal.
what is the reason for this problem? how can i fix it?
