<bumping this thread to make nVidia aware of this problems priority>

Well...

We are still waiting for the updated drivers with an option to change CRT/DFP priority order.
I read the following from http://gentoo-wiki.com/Twinview_Example
Quote:
Twinview device order

The VGA/CRT device was always the first device during testing twinview. There currently (2006/05/05) is no easy way to get around this, but NVIDIA is aware of that problem and is probably going to offer a solution in one of the forthcoming driver versions.
Why this is taking some time, I don't know. But I would guess on one of following theories:
1. Bureaucratic structure: Feedback from users to the programming teams takes ALOT of time due a bureaucratic structure within the company. We have to wait for years before any of nVidias programmer teams becomes aware of the problem.
2. Not a problem: nVidia doesn't prioritare this problem, since it's NOT a problem if we ask nVidia. They say: "It work as intended". So... rest of the universe are wrong then.
3. No priority: nVidia doesn't prioritare Linux platform at all. We have to wait years before anyone takes the step to release any new version of the driver on the Linux-platform.
4. Incompetent programmers: nVidia lack of programmers for the Linux/unix platform. We have to wait until nVidia finds someone who's paycheck arent too skyhigh and DO have some good skills within Linux/unix programming.

I believe there is a big bunch of users out there, not even aware of this thread, waiting for a solution.
Please reconsider releasing drivers as "OpenSource" so we who HAVE the skills, can fix the problem.

I second those sentiments. It's really annoying not having the ability to have my big DVI monitor as the primary display - and I bet that this is something that Windows users don't encounter.

Please Nvidia fix this problem, or seek the help of those who can.

Best wishes,

Jon.

Correct, the windows drivers can easily set what monitor is primary or secondary, or to ignore one monitor entirely... all on the fly.

I've tried specifying screen placement in KDE but it only gets me so far. I can put my panel and everything on my DVI monitor but the login dialog for KDM gets stuck on the crt, and certain informational messages/popups still come up on the crt. I have scripts that use xosd to display information, and they come up on the crt. I might be able to adjust the indent to move the xosd to the dvi, but if I switch modes and turn off the crt (which I do sometimes since I only leave on the crt when I need it) then it would be off the screen. Even if osd_cat had a screen argument, what would I use? I want the messages always on my DVI, but sometimes it is screen 1 and sometimes screen 2. In cases like this where the CRT (which is primary/first reported screen) is not always connected, it makes it much more difficult to specify screen placement. I pity laptop users because they are in the same boat with external crt's connected only some of the time.

On the other hand, if this issue were fixed/the DisplayPriority option implemented, and my DVI became the first screen reported, then all of the problems above would instantly be solved.

Hi all,

I can't understand why nVidia is ignoring this issue the way they do.

I'm a meber of the "Dell-laptop-with-powerful-nVidia-graphic-hardware" club.
When we are on the road/in the customer field, we don't take our CRT
with us - we apologize for this inconvenience.

Back in the office, we simply connect the CRT to the laptop - luxury.

Our Bill gates supporters just do this and start to work, and the linux
developers suffer from the reconfiguration issue.
Hmm, I see.
So maybe none of the nVidia developers or DELL staff leave their office to
work, they never fail to see their pot plants growing.

Now I'm going to switch on my second workstation ... thanks a million.

Looking forward to the solution ...
Dirk

Thumbs up Re: first display on twinview

Okay, I have my system working as I wanted, thanks to Savek's post on page 5. I'm so grateful that I thought I'd register and post my xorg.conf in this thread in case it helps anyone else.

Note: I'm using the 'multiple separate screens combined with xinerama' approach, as TwinView apparently still can't do this in any sane way that I could figure out.

My set-up:
I have three flat-screens - a 20" 1600x1200 ViewSonic in the centre, and two 19" 1280x1024 Sharps, one on each side. I have a PCI-E nVidia GeForce 6600 running the centre and left screens (centre on DVI, left on VGA), and a PCI nVidia GeForce4 MX40000 running the right screen.

Everything seems to be working the way I'd expect with this configuration - gdm is now loading on the centre screen, without me having changed any of its default settings.

My xorg.conf:
Code:
# Hand-crafted xorg.conf for three screens, two cards, and no clue.
# Created 2006-09-09 by denny@btsuck.org - 'denny' on irc.freenode.net

Hope that's of help to someone... it took a couple of days to get it working right, but I guess it's a fairly unusual set-up.

No. It is the standard way of doing this. I have the same setup and it works fine.
Remember, Twinview is a nvidia extension. It was invented in the days when two displays was still rare and special, and support was not present in all X servers and windowmanagers.
Now, it is common, and supported as standard. There is no need to still use Twinview, except it may be handy in some very special situations (e.g. when you do not really want two screens, but want projector output out of a laptop, or similar)
At work I have ATI cards, and thus no twinview. But the above setup still works.

This whole thread is about trying to get nvidia to make twinview work how we expect it to with 1 CRT and 1 DVI monitors. "Don't use twinview" isn't very helpful advice.

Default Re: first display on twinview

I'm addressing this to zander and any other nVidia employees on the forum.

In reference to the comments that the current behaviour is expected of the driver, we are simply echoing our discontent with using hardware that behaves differently under one operating system to another. I don't personally think it is too much to expect the card to operate the same under both Windows and Linux.

We understand that this issue is being tracked by nVidia and is planned in a future driver update. Whilst it is great news to know that the problem has been taken on board, the amount of continued activity on this thread show how important this feature is to nVidia users.

What people are essentially asking for is to be kept in the loop on the scheduled implementation date of this feature. A driver was recently released at the end of Aug and the feature was not provided. Will this feature be in the next release or will it roll over to another? How often are driver updates released? This is the kind of information we ask for.

Please keep up in the loop.

Ok, I switched off Xinerama and started running TwinView. The final straw was slow 100% CPU intensive screensavers with XGL/Compiz.

All that had to be done was plug in the LCD through its analog port and put a DVI->VGA adapter on the gfx card. No more primary display worries. Now I just have a DVI capable LCD running on analog. Oh well.

This enhancement (via bug 194782) will be implimented in the next driver (1.0-9xxx) release.

Thanks,
