Acer X221W Widescreen monitor is off center in native resolution

That pretty much sums up the problem. I can run it at 1440x900 and it works, but the pixles blend. Native resolution is 1680x1050 and the picture is beautiful, but it's shifted left about 1/3rd of the screen width such that i have a black bar on the right side of the screen, and desktop area I can't see on the left. The OSD controls only help by about an inch and a half.

This is using the Fedora 7 live disk on two different computers with the same monitor. One has an ATI Radeon 9200 SE and the other has a GForce something or other of aproximately the same vintage.

Any clues?

I managed to get the monitor working on my fc4 machine. I had to use X -configure to get a new xorg.conf, but it shows up maybe an inch off center, which is correctable using the OSD controls.

I tried using the same xorg.conf after booting in to fc7 on the same computer, which still produces the 1/4 screen displacement, and I tried

init 3
X -configure
mv /root/xorg.conf.new /etc/X11/xorg.conf
init 5

once I was already booted in to fc7 live and the display is still off. I'm pretty clear that this is an fc7 specific problem. I'm trying to get my hands on a copy of a knoppix CD to confirm, but my CD burner is currently not functional.

I'm having this exact problem in Ubuntu 7.10. I hope someone knows a way around this issue. However, In the mean time, I've gotten mine to set at 1920x1200. It's a little blurry, but it's big, seems like it's to scale, and covers the whole screen. The mode line I'm using is:

"1920x1200@60" 193.16 1920 2048 2256 2592 1200 1201 1204 1242 -hsync +vsync

I got mine working with the following modeline. ModeLine "1680x1050@60" 146.25 1680 1784 1960 2240 1050 1053 1059 1089

Once I installed fc7, I also had troubles with the driver, specifically that it didn't exist, even though it's supposedly built into the kernel I had. Because of that, I couldn't download it anywhere, but I was able to pull it directly off the live disk, and now my monitor is beautiful.

Hope this helps

Meh, no luck for me with that one . I still get the about half screen offset. I suppose it could also have something to do with my video card being excruciatingly crappy. Although, I would guess that if it will handle 1920x1200 it should be able to handle 1680x1050. But, I'm by no means an xorg expert. I guess I'll keep looking for answers. Thanks for trying to help.

I got my numbers from a program called xvidtune, which worked like magic for me. You might try that.

I think your best option is to generate your own mode lines and try different refresh rates to see what works best with your graphics cards/monitor. Make sure you know what refresh rates your monitor can handle.

Use the gtf program to generate the mode lines for xorg.conf.
