Default Is the ASUS V9520TD really dual head? (GeForce FX5200)

Hello All,

I have a really simple question which I hope someone can answer. My machine has an ASUS V9520TD video card (GeForce FX5200) which has VGA, TV-out and DVI connections. I've been trying to get TwinView up and running (with the grateful help of a number of posts in this forum), but it's not working (xorg.conf attached).

With no X running, I get the same display cloned on both monitors (identical Viewsonic flat panels). The aim is to get the X display spanning both (ie not a clone).

I found these warnings in my /var/log/Xorg.0.log:

(WW) NVIDIA(0): TwinView cannot be enabled when a GPU is shared between
(WW) NVIDIA(0): multiple X screens.
(WW) NVIDIA(0): Multiple displays connected, but only one display allowed;
(WW) NVIDIA(0): using first display

The specs on the ASUS page (http://usa.asus.com/products/vga/v9520td/overview.htm) are somewhat less-than-helpful.

So, is this really a dual-head capable card? If so, does anyone know where I might be going wrong? And if not, can someone recommend a good one that is?!

Many thanks,

Andy

PS I'm running up-to-date Fedora Core 2 (x86_64, 2.6.8-1.521smp), with the x86_64-1.0-5332 NVIDIA drivers.

Default Re: Is the ASUS V9520TD really dual head? Yup.

I know it's bad form to reply to your own posts but I solved it... Yes, the ASUS V9520TD does support twin monitors in the configuration I wanted (spanning my desktop across 2 monitors). It was my xorg.conf file that was wrong. A quick edit and woohoo! The moral of this story is don't rely on the pretty graphical tool to do the configuration :-)

Sorry for the waste of bandwidth. :-)

Andy

I know it's been a long time since the OP, but I'm having the same problem, and a search of this forum turned up only this post. Anybody have any idea what to edit in the xorg.conf? I'm running Fedora Core 4, with a self-compiled (from vanilla source) 2.15 SMP kernel. I have a GeForce FX 5700 card, and have dual monitors working, but not with TwinView. I want TwinView so that I can have the left monitor at 1600x1200 while the one on the right runs at 1280x1024. I know the hardware is capable of this because I run this configuration in Windows.

Anyway, an excerpt from my Xorg.0.log reveals the following:

(**) NVIDIA(0): Depth 24, (--) framebuffer bpp 32
(==) NVIDIA(0): RGB weight 888
(==) NVIDIA(0): Default visual is TrueColor
(==) NVIDIA(0): Using gamma correction (1.0, 1.0, 1.0)
(**) NVIDIA(0): Option "TwinView"
(**) NVIDIA(0): Option "MetaModes" "1600x1200, 1280x1024"
(WW) NVIDIA(0): TwinView cannot be enabled when a GPU is shared between
(WW) NVIDIA(0): multiple X screens.

Any help would be greatly appreciated.

If you only have one videocard, then you should have only one Device section.

Also, if you have only one videocard, any you wish to use TwinView, then you shouldn't have multiple screen sections, just one.

If you need additional assistance, please generate and post a bug report.

Thanks,
Lonni

Alright, here's as detailed of a description as I know how to give.

I currently have multiple monitors working via Xinerama (I think - it's not particularly easy for me to tell, I only converted to Linux about 2 weeks ago).

I have an old CRT capable of 1600x1200 on the left (my secondary monitor), and a 1280x1024 flat panel hooked up via DVI (direct, not through an adapter). These are hooked up to my single GeForce FX 5700 card. I've messed around with my xorg.conf file a lot, but can't get the monitor on the left to actually work at 1600x1200 while in Linux, though I run it in that configuration in Windows.

I have the Linux 2.6.15 SMP kernel that I compiled myself (oops, left out the .6 part last time <sheepish>), and am running the nVidia drivers. I guess my question to you is what bug report(s) do you want me to generate? I can boot the system normally with both monitors running at 1280x1024, or I can try to boot it at "1600x1200,1280x1024" or whatever. Tell me what's most useful, and I'll give that a shot.

I am making the assumption here that TwinView is what I want to run these monitors at different resolutions, instead of Xinerama. Anyway, for the heck of it, I'm posting a bug report of a successful boot with the already-posted xorg.conf - if that's not helpful, or you need some other info, let me know.

Also, allow me to express my most profound thanks...I can't imagine what sort of person it takes to read these forums all day and tell the newbs what to do to make it all work. <grin>

Here is an xorg.conf that I tried to use for TwinView (it failed), and the associated nvidia-bug-report.log file.

Again, thanks for all the help.

I have a few questions/comments:
0) Does removing the ConnectedMonitor option have any impact?
1) Remove "Screen 0" from the Device section. I suspect this is the root of your problem.
2) You shouldn't have a space in here: "Twinview Orientation" "LeftOf". See the README for the correct syntax.
3) Try adding a "1600x1200" mode to your list of modes in the Screen section.

If all of the above fails to help, please generate and post an updated bug report.

Thanks,
Lonni

Thank you! You're absolutely fantastic! I did all of those suggestions, and it came out working. If you'd like, I can go through and re-do it, performing each of them in sequence to figure out which one (if it wasn't all of them) that solved the problem.

Ahhhhhh, my 20" monitor is no longer going to waste as a 1280x1024 screen <grin>.

Thanks so much. Here's my current xorg.conf file.
