[DESKTOP] Dual-Head Issue [both screensavers on one screen] - Kubuntu 14.10

[Egyas]

I have an odd issue I have never run into before. I use a dual monitor set-up, and each monitor is connected to its own graphics card (Geforce GTX 465 and GeForce 210). For the most part, things run fine, except for two issues. When I reboot, the login screen background for BOTH monitors displays on my main monitor. Also, when the screensaver kicks in, they both run on the main monitor, leaving the secondary monitor visible.

Anyone have any idea what can be causing this? I do NOT run Xinerama. In fact, if I try to turn it on and restart X, it will not start. I have to edit xorg.conf and disable Xinerama to get X to start, but I think I read somewhere that it is broken w/ the more modern nvidia drivers.

Thoughts? If you need anything specific to look at, let me know and I'll gladly post it. Here are pics of the screensaver and login screen issues (ignore the messy desk)...

Here's my xorg.conf file...

these are sometimes tricky,
i think the background image showing up on both monitors is correct? but login prompt on only one?
i love how u call it a major issue he he
not sure about the screen saver...sorry
on another note shouldnt the GTX be able to drive 2 monitors? even the 210?

Background on both is what I want. I just need to figue out why at login both backgrounds are on 1 monitor, and why both screensavers run on a single monitor.

i love how u call it a major issue he he

Oopps! lol Didn't even realize I said that. I removed the work "major".

It can, but in the past I have had issues of the secondary screen resizing or changing when I played a fullscreen game, etc. So to avoid that I use a second card for the secondary monitor.

As you can guess, I'm a n00b at desktop configuration. I have worked with Linux for years at the server level (RedHat), but NON of my servers at work have a GUI. CLI only. So desktop configs often escape me.

You really kinda have two issues since the log in screen is controlled by the Display Manager and the screensaver isn't. I'm not sure which DM 14.10 uses by default (could be SDDM or LightDM), but I can tell you that with dual monitors on a single card, LightDM (the default on 14.04) worked as you desire - both screens displayed the background and the login screen followed the mouse. I don't use a screen saver ever (I use dpms blanking) but I suspect you'll have to program a script to launch two screensavers with targeted to each screen.

Reports I read about early SDDM bugs show dual screen results in a mid-placed (divided) og in but I suspect those are dual-head rather than dual card setups.

Have you considered trying a single card? They're much easier to set up IME. Dual cards are usually reserved for a dual-seat set up. Nvidia twinview works very well and if you don't like that, xrandr can handle it also. IMO, twinview can solve your problems.

Unfortunately, I can't test for you since I no longer use dual screens or dual cards - opting instead for a single card and a larger monitor. It sure makes life easier!
