[gentoo-user] DPI is giving me a headache!
Hi All, I changed the monitor on a box that runs kdm/KDE and the fonts on KDE apps are giving me a headache from eye strain. This is particularly bad when working at a console (white letters on black background) and KDE text editors (with black letters on white background). Essentially, the antiailiasing seems to alter the consistency of fonts in an irregular manner causing them to blur (differently) across the screen, as if the monitor resolution is out of sync. The resolution in xorg.conf is set at 360 290 mm, but the DDC picks this up on its own anyway, whether I define it in xorg.conf, or not. I have no modeline set. All I can think that is amiss is the DPI. I seem to be getting a DPI of 90x89: $ xdpyinfo | grep resolution resolution:90x89 dots per inch Could this be the cause of my headache and how should I fix it? -- Regards, Mick signature.asc Description: This is a digitally signed message part.

For example, if you run a 1280x1024 at widescreen, each 6th pixel or something is stretched to consist of 2 physical pixels to widen the screen out to fill the entire display. I hope that explination makes sense - clearly there are other, better ways to use widescreen in a case like this. i would make sure you're running in the screen's native resolution if it's an LCD, else make sure you're running at a resolution that fits the aspect ratio of your screen. -- gentoo-user@lists.gentoo.org mailing list

Yep, that's pretty much what I think it is. Stretches and blurs along the width of the screen, every few pixels. I thought I *was* using the native resolution. Of course DDC may not be picking up the right dimensions in the first place. This is not a wide screen, just a 1280x1024 vanilla resolution. The monitor is a NEC MultiSync LCD 1860NX.

You might want to remove them and try without. 2) your ATI device has quite a lot of settings. If you don't need them all, you might want to remove or comment out what you can. They might affect the output in unexpected ways, although I'm no ati expert. -- gentoo-user@lists.gentoo.org mailing list

DisplaySize 360 290 #digital, oh wait, you said that doesn't change anything. Hm. You can set your DPI with the nvidia driver. But I am not convinced that it is X, the drivers or the monitors fault. The font antialising in linux is just bad ;) hm, oh, and try whatever Dan told you ;) Maybe enabling backingstore helps too. -- gentoo-user@lists.gentoo.org mailing list
