Problems with widescreen resolutions (1280x720) on 15" widescreen TFT with nvidia


I have an nVidia GeForce 6600GT and a 15" widescreen TFT monitor. I'm using the latest release of the nvidia drivers (as 7/1/06). My distro is SuSE 9.2.

I'm having some interesting problems getting the proper resolution to work, though. I've set the config file to the correct settings, and used a modeline generator to get the right modeline for this resolution. I've also used SaX2 to set 1280x720 as my resolution. The strange thing is that when I do this the resolution is somehow stretched... items appear stretched vertically, and the screen crops like a virtual resolution; ie you can move the mouse to the top of the screen to reveal more desktop.

Now, it appears as though the widescreen (16:9) res has been stretched to a square, is this a driver issue? Do I need to set some sort of geometry option, or is there a way to turn on 16:9 ratio in xorg.conf?

Basically, I'd just like to get it working...

Any ideas or help would be appreciated. If you want any more details please ask.

Thanks in advance.

This is odd. My first assumption is that Sax2 is doing something (or undoing something) you changed in xorg.conf with your modeline.

How do you have it connected to the monitor, VGA or DVI or something else? Also, check that your modeline isn't the culprit (try other ones that google turns up, just to see if they are closer).

I don't think it's a driver issue (although I haven't heard anything great about the new driver, I don't think it would be causing this). My guess is it's something to do with your configs, and further, with how Sax2 is treating them.

Cool

Yep, I consider it to be quite strange...

The monitor is connected to the PC via VGA, and I've tried a few different modelines, and so far none have given me anything better, and I've tried commenting in and out a few different options to see if it would make a difference: so far thing has worked.

I'll just run and get a copy of my xorg.conf to see if anyone can find an obvious culprit in that.

It has been my fortunate pleasure to not need a modeline with my setup (yet). I have heard that connecting via DVI will change this, but for now, with the VGA connection, it's working just fine as is.

Here's a copy of my xorg.conf if you want to give it a try (not the whole thing, I use Gentoo and probably a different version of X.org but you could try the different lines like in the Monitor section):
Code:
# Any number of monitor sections may be present

Section "Monitor"

    Identifier  "Hansol"

# HorizSync is in kHz unless units are specified.
# HorizSync may be a comma separated list of discrete values, or a
# comma separated list of ranges of values.
# NOTE: THE VALUES HERE ARE EXAMPLES ONLY.  REFER TO YOUR MONITOR'S
# USER MANUAL FOR THE CORRECT NUMBERS.

    HorizSync   31.5-50

#    HorizSync  30-64         # multisync
#    HorizSync  31.5, 35.2    # multiple fixed sync frequencies
#    HorizSync  15-25, 30-50  # multiple ranges of sync frequencies

# VertRefresh is in Hz unless units are specified.
# VertRefresh may be a comma separated list of discrete values, or a
# comma separated list of ranges of values.
# NOTE: THE VALUES HERE ARE EXAMPLES ONLY.  REFER TO YOUR MONITOR'S
# USER MANUAL FOR THE CORRECT NUMBERS.

    VertRefresh 40-90

What's even funnier now that I look at that is that this is the old xorg.conf from my 19" CRT monitor, I suppose I have only changed the Modes since then to add the 1280x1024 (which I don't understand, it should be 1280x720).



Lucky me that things just 'work' eh

Must be my TV that loves me. (In a Yoda voice)Some tweaking I'll do...

Cool

Just rebumped this thread to see if anyone has any more ideas...

I found that the xorg.0.log file is showing a line from the nvidia driver. It says that "Virtual resolution has been determined to be 1280x768".

That is clearly the problem. Any idea how I switch off that auto-detection? There is no virtual resolution set in the file
