Unhappy Linux makes me ill ...


I couldn't think where else to post this so here goes ...

I recently converted to SuSE 9 on my desktop machine, normally I wouldn't use linux as my desktop OS because of my love for games and the need to use a few windows applications for uni. However I decided to give the 'desktop linux' idea a go, the only problem is that after any long period of time I feel really ill using X, my eyes feel tired really quickly and I feel sick, I'm running at the same refresh rate as I was in windows (1600x1200@85Hz) yet it just 'feels' wrong if that makes any sense ? any help anyone could offer me would be great

EDIT: I have an iiyama vision master pro 454 19" CRT

Do you have all your horizontal refresh and vertical sync rates correct for your monitor if the xf86 config?

yup I'm pretty sure they are correct, thing is, my monitor reports my vertical and horizontal refresh rates to be exactly the same as in windows, so I don't know what could be causing it

Then 19 more bits like the last 7 lines, but since it says the default is 0x21 I've only included that

not an expert here, but it's using 16-bit for depth. change your /etc/X11/XF86Config-4 file where it says "DefaultDepth 16" to "DefaultDepth 24". you'll have to make the change as root. see if that makes it any better.

Honestly, this fix is probably more money then you'll want to spend, but... LCD monitors are amazing for eye strain. If you stare at monitors for hours on end, you'll be all the better.

Might also want to try something as simple as changing the background color/image. You might be using a color that just doesn't agree with you

Or (and I hate to say it) try using a window manager that more closely resembles Windows. There are a couple out there.

24-bit as opposed 16-bit colour makes a big difference, too.

And remember to take breaks - once an hour at least you should take 10 minutes to do something not screen related.

A more frequent break rate, such as getting up every 20 minutes is recommended by many work/health related inquiries/reports.

Changing your work position while working also cuts strain and room lighting is of the utmost importance.

Except thats impossible to do when I am engaged in a heated multiplayer online game (netpanzer, etc.) over Linux (and Windows yes).
