Question solution for non-aligned screen?


hi all,

i've installed dual boot winxp and fc5.after the installation of fc5,the screen is aligned to the right more,even after i choose 1024 x 768 screen resolution.so i've to adjust manually using the panel on the monitor to shift it back in place.This,after which there seems to be thin black empty circumference surrounding the whole screen.I've realised the same when i boot back into winxp.Any idea whats the problem and any solutions?

You can define a custom Modeline to adjust the exact timings you want (depending on what video card you have--what is it?). I'm not familiar with utilities for real time adjustment of timings in Linux--I just use trial and error modifying from one created by a Modeline generator.

This is because I already had these issues before switching to Linux, and first figured out how to do it in Windows using the program "Powerstrip". Powerstrip is able to import/export Linux modelines, so I've used modelines I had exported from Powerstrip ever since I switched to Linux. I haven't bought any new monitors with such issues, so I haven't needed to create new modelines from scratch.

I had a similar problem with my nVidia card and my monitor...I had to install the nVidia driver to correct it because the generic nv driver wasn't aligning the screen correctly.

Oh--there's also one possible EASY solution. You can change the refresh rate. Often the screen alignment will be different if you change the refresh rate. Personally, I like using a rate between 75hz and 85hz.

Should think what you need is 'xvidtune' which will be in there with X.

Use it and then get it to print out the appropriate entry in the X configuration file. Past this over the appropriate entry in the X configuration file. Ignore the dire warnings it issues.

Yes that's the problem...change the refresh rate in linux to 60hz...windows is correct, you can damage your monitor if it's set too high. If the problem persists it could be something else but at least you'll have changed the refresh rate for the better.
