Rep: Reputation: 0 display is off-center on my Acer X221W Widescreen monitor

The native resolution of my Acer X221W is 1680x1050. When I have the display set to that resolution, the picture is off-center about 1/4 of the screen width to the left and the OSD controls only help an inch or so. At 1400x900 it centers appropriately, but is fuzzy because of blending. The monitor is running at 60hz, and the same settings on a windows machine are working just fine.

I'm running Fedora 7 off the live disk, and my graphics card is an ATI Radeon 9200 SE. Fedora 7 automatically detected both my video card and monitor correctly.

You have to generate a modeline for that resolution and add it to the monitor section. The easiest way is probably to use a program called xvidtune to do this. Below is an example of a modeline
Modeline "1680x1050@60" 154.20 1680 1712 2296 2328 1050 1071 1081 1103
You can play with the bold numbers (this is what xvidtune does as well); decrease them slightly and the picture will move to the left). I have done the manual exercise once, but can't remember anymore exactly. There is one specific article on the internet that explains it nicely with examples so you cn do it manually. After 30 minutes search, I gave up on finding it (sorry).

References scroll down to find some info about xvidtune

calculators used to calculate the above modeline calculates a slightly different modeline which (if I'm correct) results in a picture more to the left with the default settings

Hope that this helps.

Thanks ^_^
xvidtune worked perfectly on the live disk. I updated fedora, and now the radeon driver won't even work, but once I get it working, everything should be peaches and cream.
