Hello. I have two different size monitors on my box. gNewSense will not load in this case. It works fine with only one monitor. One is ~1024x768, and the other is 1900x1200. I'm running a Shuttle with a Q9550 a GeForce 7600 GPU, and 4GB RAM. Thanks in advance!

Okay. I did get gNewSense installed, but the OS automatically defers to the lower resolution of the smaller monitor. Any fixes for this? Thanks again! : )

I think it's probably your video card. I've got one PC with an nVidia GeForce 6600 card, which gives me a really low resolution without the proprietary drivers. Without them, I can't get any decent resolution; nor use my TV as a second screen (for movies etc) properly :(

If you do an online search for Linux drivers for your card (or cards close to it), it may help; but I think any drivers you'll find will be proprietary. :/

I'm aware of the xfree86-nv driver but I'm not sure about the license of that; or whether or not it works with your card.

Thanks for the reply Imperium. My screen resolution is fine (1900x1200) when just the one monitor is installed, but reverts to the smaller resolution when the two are being used.

Ehh, weird. I get a crappy resolution, no matter if there's one or two monitors (well, monitor and TV) attached!

Is your main monitor (the one that gets a good resolution) connected through the DVI or VGA port (Respectively "yellowish white" and blue-coloured)?

I would assume that on a free OS the DVI port is the one that gets neglected (because of the proprietary hardware), but I'm not sure: today, when I tried my two-screen setup without the proprietary drivers, I got the same low resolution on both :/

Also, have you tried to manually edit your /etc/X11/xorg.conf file (as root/sudo) to include two screens with the correct resolutions? I can't point you to a guide but google (http://www.google.co.uk/search?hl=en&q=%22xorg.conf%22+two+screens&btnG=Google+Search&meta=&aq=f&oq=) throws up a fair bit of results for that (didn't go through them because it's early Sunday morning and alcohol has taken over my brain).

The wiki forum won't let me edit, so sorry for the new post:

today, I actually tried the "manually editing" xorg.conf - the only reason it failed was because it refused to accept the resolutions. It always reverted (into some kind of "safe mode") to the lowest resolution possible. I could get two screens - and even have the GDM login window on both screens (which doesn't happen with the proprietary drivers installed) - but at a very low, unusable resolution.

I blame nVidia :(

Let us know what results you get!

As far as I can tell, none of the nVidia cards have free drivers that support the dual heads. I have a card that I could get to work, but it stretched the one screen over two monitors. I gave up. I went and found a cheap Rage card ($20) and plugged it in, used the r128 driver, and set up xorg.conf manually. I'm sure things will be different for different configs, but this works nicely. The only bug is that once I log out and then try to log in, only one monitor works, the second one is off... Don't know why, but different systems work differently with it. When I used to use Ubuntu (9.04) worked fine but for some frizzy lines that were a little annoying in the second screen. Now I only use gNS and I just restart if I need to. I have a feeling this could be fixed by someone more savvy than I. You're welcome to check out my blog entry at www.semiantics.com (should be on the front page still). I wrote it using F10 and 8.10, but it works fine with gNS.
