separate x screens with nvidia

Hello all...

I am running Slackware X68_64 and I just purchased a second monitor. I enable separate x screens with nvidia-settings and when I reboot I get a black screen and when I put my mouse over to the secondary monitor I get X for the mouse pointer.... Than after a while it just blacks out.... Any Ideas?

Thank You for the help.

When I open nvidia-settings as root I get:

Invalid display device DFP-2 specified on line 52 of configuration file

Any body out there?

Thanks

What are you wanting to accomplish?

Two sepperate X sessions - one on each monitor?
Or a single X session spanning one huge desktop? - The Window manager thinks there is a single gigantic monitor, maximizing a window spans both monitors.
Or a single X session with dual monitors? - The Window manager knows there are 2 monitors, maximizing an application spans a single monitor. You can drag application windows for monitor to monitor.
Or something else


Nvidia has decent documentation
ftp://download.nvidia.com/XFree86/Li...gtwinview.html

Personally, I use option 3 above. Single session, dual monitor. Provides 3D acceleration, desktop effects, and VDPAU
Code:

disturbed1,

Thanks for the reply. I am trying to use option 3. I just found out my issue. After I get option 3 enable as you describe the monitor flickers and I can see my desktop for about 5 seconds than it turns black. Now here is the funny part. I can get a flash light and point it to the monitor and I can see my desktop. WTF!?! lol so it looks like some how its not getting light via the lcd only for a few seconds?
Maybe a bad monitor? Your thoughts?

Thanks for the help!

Bad monitor, bad cables, or bad GPU.

Swap the cables on the back of your monitors - if monitor #1 is now dark, swap the cables at the GPU - if monitor #1 is still dark = bad cable, if monitor #2 is now dark = bad secondary output on GPU. If monitor #2 never lights up = bad monitor.

Thanks for the help disturbed1,

The issue was a bad monitor. Now I have the monitor working but the desktop is bigger than my monitor. How can I fix that?

Thank You,

My resolution is 1920x1080 which is supported by the monitor.... I cant seem to figure out why is the desktop bigger than the viewable area.

Any ideas?

TIA.

This might happen when resolution (or resolution options) are specified in xorg.conf, or the .nvidiarc file. The name/option is panning (IIRC).

If you're like me, you'll soon start to wonder how we got by in the past with only a single monitor. Makes everything so much easier. When I want to watch a movie my Girlfriend will not enjoy, I'll expand MythTV to take up both monitors. Scoot back plug in the headphones, and enjoy.
