Hi,

Currently testing 2.6.11.10's desktop capabilities. One small issue so far.
When I open Konsole (KDE) and perform some operation that has a lot of
screen output (tar xvzf OpenOffice_xxxx.tar.gz or the likes), I get small
dotted lines here and there on the screen. I wonder if this is an issue
with my (latest) Nvidia driver. Anyway: don't have this problem with stock
2.4.29.

Any clues?

Check to see if the dots are remains of "decenders" on
characters. That would be the bottom dots from g, y, p, j, and
q. You can probably test that by simply typing in a series 'g'
characters on the command line, and then backspacing to clear
them. If that leaves a line of dots...

I don't know precisely what the problem is, but it is with X,
not the kernel, your video driver, or whatever.

It has something to do with the way fonts are generated. I've
had loads of problems trying to find a nice font to work on a
1024x768 screen without seeing those dots. Other resolutions
are not as much of a problem, but the effect can certainly be
demonstrated.

The solution is to use different font parameters.

Solution space: 1) test: works in 800x600, goes strange in
1024x768 --> 2) install 100 dpi fonts. (o:<

That's exactly the kind of "change in parameters" that has to be
done. It depends on exactly which font you use though, as to
whether that specific change will do anything or not. I can
certainly find ways to get the exact same effect with 100 dpi
fonts!

My particular problem is that I like 100x30 xterm and editing
screens, fonts which provide a nice form factor for that,
*and* (the list goes on...) are san serif with easy to recognize
';' and ':' or ',' and '.' characters. It happens that the
-misc-fixed-medium-r-semicondensed fonts are just about perfect.
Except finding size width and height parameters that work well
with a 1024x768 resolutions is impossible. Since the only place
I use that resolution is on a laptop, a few compromises are ok.
So if I remember right, my screens don't end up 100x30 on the
laptop.

Truetype or the older 'Speedo? I forgot the 'rules', odd or even
pixel height, regenerating the font control files, was 4 years ago
it mattered Used to run Xvnc for remote NEdit, now I use vim
with PuTTY. 100 dpi easy answer for some, though I remember taking
ages to pick a good font-set for monospace NEdit use.

I get 100 x 37 on 800 x 600 laptop CLI vesafb 8 x 16 VGA charset

I found the solution, way off. Forgot to configure nvidia chipset in my
kernel config)

Included AGP and nvidia chipset directly into the kernel. Works like a charm
now.

cheers,
