Do you have a link to "the correct debian way" to enable fontconfig/Xft
for text rendering? (Me being no X11 expert ...)
It's app/toolkit specific. E.g. with xterm you can enable it with -fa
and related options.
Is it a fontcontig and Xft, or is it a either fontcontig or Xft?
It's mainly about Xft. Most users of that also use fontconfig for
selecting the fonts to use, but that's not required.
Most apps/toolkits have used the modern text rendering infrastructure by
default for a long time, but a lot of terminal emulators are still
holding out for some reason.
Thanks a lot for your help! It lead me to a nice workaround (even if the
original question KMS=0 vs. KMS=1 is not really solved by this).
The only thing I did (after reading about Xft and fontconfig) was to
install rxvt-unicode, which has xft support.
Running "time seq 100000" with various terminal/font combinations gives:
xterm -fn 9x15:
real 0m50.001s
user 0m0.180s
sys 0m0.428s
xterm -fa 9x15:
real 0m7.785s
user 0m0.116s
sys 0m0.180s
rxvt:
real 0m11.707s
user 0m0.140s
sys 0m0.252s
urxvt:
real 0m0.994s
user 0m0.176s
sys 0m0.308s
So for some reason urxvt seems to use a font path, which is as fast as the
speed having lenny installed. The Xresources for this test were:
% cat .Xresources
xterm*background: black
xterm*charClass: 33:48,37:48,45-47:48,38:48
xterm*font: 9x15
xterm*foreground: white
xterm*saveLines: 1024
xterm*scrollBar: false
xterm*visualBell: true
xterm*visualBellDelay: 100
rxvt*background: black
rxvt*charClass: 33:48,37:48,45-47:48,38:48
rxvt*font: 9x15
rxvt*foreground: white
rxvt*saveLines: 1024
rxvt*scrollBar: false
rxvt*visualBell: true
rxvt*visualBellDelay: 100
urxvt*background: black
urxvt*charClass: 33:48,37:48,45-47:48,38:48
urxvt*font: 9x15
urxvt*foreground: white
urxvt*saveLines: 1024
urxvt*scrollBar: false
urxvt*visualBell: true

Thanks again!
