Hi all, Has anybody figured out how to control permissions on the /dev/nvidiactl under OpenSuSE 11.1? Thanks. Boris. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

OK, figured this one out. There is a file called /etc/modprobe.d/nvidia whose content look something like the following: -------------------------- options nvidia NVreg_DeviceFileUID=0 NVreg_DeviceFileGID=33 NVreg_DeviceFileMode =0666 -------------------------- All you have to do is change the mode in NVreg_DeviceFileMode=0xxx to what you desire.

OOC, why would you need to change this? I have: crw-rw---- 1 root video 195, 255 2009-06-15 08:07 /dev/nvidiactl Wouldn't that be correct? Xorg runs as root. I ask all this because I still cannot get desktop effects to work with a supported nvidia card (all in an earlier thread in these parts). -- Roger Oberholtzer OPQ Systems / Ramböll RST Ramböll Sverige AB Krukmakargatan 21 P.O.

Roger, /dev/nvidiactl is a tool for individual (non-root) users to control the function of their NVIDIA card. To make it accessible to everybody I set the access mode to 666. Try it out - I think that could fix your desktop effects problem. Boris. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Unfortunately, no. The ONLY desktop effect I get is when I click on the top border of a window, it becomes semi-transparent. It stays this way while I move it. Nothing more. I have tried a new user just in case something is odd in my directory. Nothing works. I am convinced the window manager is the problem. It is kwin (4.2.4 (KDE 4.2.4) "release 2"). The card is an NVIDIA "GeForce 9400 GT/PCI/SSE2" running NVIDIA driver "3.0.0 NVIDIA 185.18.14". -- Roger Oberholtzer OPQ Systems / Ramböll RST Ramböll Sverige AB Krukmakargatan 21 P.O.

You could be right, it could be the window manager or something else in the KDE. If you don't mind wasting some time, potentially, you might try playing with the newest KDE, KDE 4.3 (OpenSuSE has it under "Factory", I think).

I was thinking of doing that. I would like to sort out the set of repositories that should work together as a unit: X11 Qt KDE For a new NVIDIA card supported by the current NVIDIA driver, should X11 be Xorg or Xgl? Or both? There is the one-click install, but that does not obsolete older repositories. Or even change the priority of the stuff installed to be greater than whatever was already there. I have: /repositories/X11:/Compiz/openSUSE_11.1/ /repositories/KDE:/Backports/openSUSE_11.1/ /repositories/KDE:/42/openSUSE_11.1/ /repositories/KDE:/KDE4:/Playground/openSUSE_11.1_KDE_42/ /repositories/KDE:/KDE4:/Community/openSUSE_11.1_KDE_42/ /repositories/KDE:/Qt44/openSUSE_11.1/ /repositories/X11:/XGL/openSUSE_11.1_KDE4_Factory/ http://download.nvidia.com/opensuse/11.1 All with a priority of 99. The 11.1 original distribution and updates have a priority of 100. Anyone have this sorted? -- Roger Oberholtzer OPQ Systems / Ramböll RST Ramböll Sverige AB Krukmakargatan 21 P.O.

On a test 11.1 machine, I did this update to KDE4 Factory. Then, I started the KDE compiz setup program. And guess what: it make more things work. The odd thing is that the settings here have nothing to do with those in the ccsm program. They seem not to share anything. I have been under the impression that these two programs were an interface into the same configuration. Well, that is not the case! In fact, in the KDE config utility there were fewer plugins to configure, and fewer per-plugin settings to fiddle with. Even the key presses are radically different. In the KDE compiz setup program, starting cube rotation is Alt-F11 (it takes two hands - and I have big hands!), whereas the ccsm keys are a key+mouse combo. The menu that lets you redefine the keys does not accept mouse buttons (AFAICT) All this is not the case with KDE 4.2.4. That still does not work, no matter which config program is used. -- Roger Oberholtzer OPQ Systems / Ramböll RST Ramböll Sverige AB Krukmakargatan 21 P.O.
