1680x1050 resolution being finicky - Acer x203w

Hi yall, just recently I realized my resolution in linux was a little less than the resolution when I'm in Windows (I have to dual boot for school). I did some research, and low and behold I have a max resolution of 1680x1050!

I added the "1680x1050" to the 24 bit depth line of my xorg.conf file and switched the resolution, but one problem remains. It appears my screen is shifted to the left - I have a 1/4 inch black bar on the right and my desktop is cut off on the left.

Can anybody offer any advice? I'm using a 20 inch Acer x203w Monitor and a NVIDIA Geforce Video card.

No, my xorg.conf recognizes my monitor as 'Generic Monitor' e.g.:

Code:

I'm using a very unholy Nvidia display driver which I think might be the problem. My xorg.conf looks like this:

What do you mean by "unholy" driver? the "nvidia" driver is indeed the one to use.

the only thing that looks funny to me is this:
Quote:
DisplaySize 1680 1050
I would take that out.

The other thing to try is to make sure the Horiz and Vertical scan rates are correct for your monitor.

I all else fails, try a modeline. You can generate it using the "gtf" utility. Smedley's post shows how it is used.

If you leave these lines out completely (or, just comment them out) modern distros will query your monitor with EDID for the correct values.
pixellany is right about, DisplaySize width height
This optional entry gives the width and height, in millimetres, of the picture area of the monitor. If
given this is used to calculate the horizontal and vertical pitch (DPI) of the screen.

Thank you Pixellany, that worked.

I found out that if I push the 'Auto' button on the front of my monitor, the black bar goes away. BUT if I reboot into windows, the bar appears at the left - as if the two operating systems aren't aligned. So it's just an annoyance of pushing the 'Auto' button everytime I switch OS's. Any thoughts?

I think you'll have to set up a modeline, either with gtf as pixellany suggested, or xvidtune which allows changes to the timings to be seen as you adjust them. Start it from a terminal. Make adjustments. When you click on "show", it prints the modeline to the terminal and closes. Then you need to copy that modeline to your xorg.conf and restart X

I copied the modelines, and my screen still shifts when I switch operating systems. Any other ideas? or could it be an issue with the Gates OS?

Did you use gtf or xvidtune to generate the modeline?
I hope you used the latter. If so, please post your xorg.conf (we do not need to see touchpad, mouse or font entries).

I don't know, but I'm not messing with windows - too frustrating, and I no longer know what I am talking about (I quit at win98).
I think the best way to fix this is to boot to win, press the "Auto" button, then boot to linux and use xvidtune to generate the modeline you need to enable linux to work with the settings windows requires.
Then we just need to check that you have put the correct entries in the right places in xorg.conf

Did you use gtf or xvidtune to generate the modeline?
[1]You haven't answered my question

I have searched the acer site:
http://csd.acer.com.tw/acer/URMUL1.N...=50&Expand=4#4
for your monitor, which you said in your first post is a "x203w" - it doesn't seem to exist so I cannot check its manual - [2] do you have a link to it?

But (from your xorg.conf)
Code:
    HorizSync       60.0 - 100.0
    VertRefresh     75.0
Does not look right for an LCD display.
[3] Where did you get these numbers from?

As I said before, if you take these lines out, X will try to ask your monitor for the correct values, and use them to work out the timings.
Some monitors do not reply correctly, but we will find out ...

So, for now, we'll try and let X sort it all out:

Remove the HorizSync and VertRefresh lines from your xorg.conf
Also remove all modeline lines.

Then restart X with a <CTRL-ALT-Backspace>

[4]Any better?

If this fails we'll go back to generating modelines, but this should not be necessary.

The red bits need answers
