My eyes hurts.

McZ · 2008-02-02 00:29:44

So I have once again tried to take the step from Windows to Linux. But after some browsing the net or playing with gimp or something else in X my eyes hurts really bad. This does not happen in windows so I assume X-windows rendering the image slightly different than windows.

I am running X in 1280x1024@75hz the same as in Windows, though in windows I can choose 32bit color and linux (nvidia drivers) only offer 24bit does this make any difference? last 8 bits is only for alpha or something I think.

I have changed the font in linux so they look like the windows fonts, guide : http://www.sharpfonts.com/

I have even modifed a theme to use the same colors as windows does, and I have tried a bunch of other themes. And I am using the same background.

I have used guides to adjust my graphiccards contrast/brightness/gamma settings (not my monitor since monitor the settings is good in windows) like this guide : http://www.tftcentral.co.uk/articles/calibrating.htm But that just makes things worse, like bad colors and dizzy picture.

I'm running out of ideas of what to try, I can't understand why my eyes hurts after a while in linux.

So anyone have any ideas I can try? I'm going to test another DE, using XFCE now.

My system is : Core 2 Quad q6600, 2gb ram, nvidias 8800gts 320mb if that could be an issue or something.

CRT or LCD Monitor?

placebo anyone?

If anything, hinting or antialiasing is generally a good thing check the wiki for how to change it (if your DE doesn't provide any configuration options)

As another option, you could compare screenshots of the same website from both oses in either; if there's no difference its either your mind playing tricks, or the video driver applying hinting (some do; then it might not show up in a screenshot).

is it just your fonts bothering you?

ibendiben · 2008-02-02 07:47:36

It is definately the backlight or brightness. I had that problem, here is some solutions:

Hope this is new for you and solves your problem

I have been playing with the hinting settings I have found in XFCE, altough it either looks like crap or nothing happens.

Actually nothing bothers me, the picture looks good. But it still hurts my eyes after a while so I can't use it for long.

I can't change any backlighting. all I get is 'No outputs have backlighth property'. and /sys/class/backlight is empty.

Yeah, as that is only for laptops, or monitors with back light. Well, in theory, since I don't have Windows, I can't say it is true or not, but my eyes do hurt after some while. But, My eyes do hurt at University as well, with Windows, I just can't remember if it is the same feeling or something different. I'll have to do more research on this, in fact this topic is interesting.

For me it's switching back and forth between Windows and Linux. At work I use Windows with both GUI apps and terminal apps. When I do that all day my eyes hurt. Then I come back to Linux and the same thing happens. If I only work on my Linux boxes (weekends), then my eyes are fine for many hours at a time.

If anyone cares (and I know you do) the newer Cairo libraries make the situation much nicer on Linux. I'm currently running Cairo 1.5.8 and things have never looked so nice.

OK, I have a LCD, too; the DVI input drastically improves display on Linux. However, I'm not sure about the improvement on Windows. (video drivers could make adjustments that we don't know about)

17 inch monitor running 1280*1024 resolution is a stretch if it's not a LCD. that might be one of the contributing factors to your eye irritation problem.

If anything, I think the libcairo-lcd packages make reading in linux much more pleasant than in windows.

I don't know why, but I activated compiz-fusion some hours ago, and my eyes are not hurting anymore. At least if they are going to it is lasting longer without the hurting sensation. In fact I have to do more test on this.

it may be the dithering your display probably is using if it is a TN-panel in it.
dithering is a technique used to fake more colours.
but then again, the change of OS shouldn't have any impact on this effect.

Can anyone point out what is going on, where should I start searching more help? (and possibly which key works should I use for search?)

I'd try a modeline from here @ 60Hz. Put it in the "Monitor" section of your /etc/X11/xorg.conf:

Section "Monitor"
...

# V-freq: 60.00 Hz  // h-freq: 74.69 KHz
Modeline "1600x1200" 170.89  1600 1688 1896 2288  1200 1200 1203 1244

EndSection

Then refer to it in your "Display" section:

Section "Screen"

...

    Subsection "Display"
        Depth       24
        Modes       "1600x1200_60"
     EndSubsection
EndSection

I fixed a twitch in my display this way.

I switched from the older ones to this AUR Version as well but cant really notice a differnece... I didnt pay much attention to it tho, just needed it for ff3 to build.

I like what my fonts look like though and I dont have problems with windows oder linux font rendering.
Id say its just more work for your eyes, you dont have to concentrate that much in your windows environment which youre used to.
