Slackware 13 and NVidia Compositing
 

I upgraded my desktop to the new Slackware today, and it's definitely very cool. However, when I went to enable desktop effects in the display settings, I'm told this:

Compositing is not supported on your system. Required X extensions (XComposite and XDamage) are not available.

I have an old NVidia GeForce 5200 and I'm using the most recent NVidia driver from their website. Using this command:

nvidia-xconfig --add-argb-glx-visuals --allow-glx-composite --composite --disable-glx-root-clipping --damage-events --randr-rotation --render-accel --nvagp=agpgart

I basically tried enabling everything I could think of, and the xorg.conf file was updated appropriately, but still no luck.

I also have xinerama enabled, and it's working fine.

Any ideas?

Xinerama and compositing are mutually exclusive as far as I know. Can't you use xrandr instead of xinerama?

The "FX" 5200 uses NVIDIA-Linux-x86-173.14.20.pkg1.run

Did you run nvidia-xconfig without all the options? That's all I did on my system. On reboot, the automagic stuff did the rest.

I also recommend using the SlackBuild for installing the nvidia driver. As usual, alter the slackbuild for your nvidia driver version (and pkg#). Since I installed the nvidia driver with the .run package the first time I removed the .run package with --uninstall and renamed the xorg.conf before reinstalling the nvidia driver with the slackbuild

Ahhh, I see. I had previously had it configured as a dual-head system, but since KDE4 doesn't support that I just checked the "Enable Xinerama" box in the nvidia-settings dialog. I didn't realize there was another way to do it.

Thanks for the help!

Check the "krandrtray" program of KDE4.

Resolution
 

I have the same setup as the OP. I followed the steps here, and have tried several other things. While I can get X to run and KDE to configure, I can't seem to get the 1680x1050 resolution that I had set up on KDE 3.5.10. My monitor's native resolution is 1680x1050 so everything look so much better that way. I know it must be possible, but X doesn't seem to want to pick up Modes or ModeLine in xorg.conf.
Also, there is no option for that resolution in nvidia-settings. The highest it goes is 1600x1200.

Currently, I am using the nvidia driver and kernel (legacy) packages from Slackbuilds and have xorg.conf set up from nvidia-xconfig.

PS Let me know if it is appropriate to bump or if this warranted a new thread. Nettiquitte is not my strong suit (although I'm working on it.)

I think I see what's going on here. I have a ViewSonicVX2235WM Monitor using a DVI connection. For whatever reason the EDID seems to be indicating a 1600x1200 native resolution. It looks like the problem is actually a monitor problem and not x or nvidia. Now how to address this. Do I look to correcting the incorrect information from the monitor or look to overriding the settings. I believe that xorg.conf overrode the settings with Slackware 12.2. That may be the way to go.

The ViewSonic vx2235wm sends a different EDID for the analogue and digital interfaces. The digital is dysfunctional in that it limits the pixel clock to 135.0.

I added to the Device section in xorg.conf: Option "ModeValidation" "DFP-0: NoMaxPClkCheck"

Restarted X and finally...1680x1050.

One more thing...for almost two years I have been trying to get this resolution in Windows and could not do it. Windows has no xorg.conf to edit so if it won't work, that's that.

I thought I would post this since I found numerous occasions that ppl were having this issue with the dual head (DVI VGA) nVidia cards with the FX5200 GPU.

I hope this is helpful.
