Hi Felix:
Here is how I configured PreferredMode _for an old server_ (Debian Lenny)
in the Monitor section:
#gtf 1024 768 85
# 1024x768 @ 85.00 Hz (GTF) hsync: 68.60 kHz; pclk: 94.39 MHz
Modeline "1024x768_85.00" 94.39 1024 1088 1200 1376 768 769 772 807 -HSync +
Vsync
Option "PreferredMode" "1024x768_85.00"
I found in the past that PreferredMode would not work with Intel if you used
a standard modeline name such as "PreferredMode" "1600x1200" like you do in
your xorg.conf. Instead, I suggest you use gtf to calculate a 1600x1200
modeline, and use the generated non-standard modeline name with a suffix
corresponding to the vertical refresh rate. No guarantees, but specifying a
special modeline like above with a non-standard modeline name was the only
way I could get PreferredMode to work in the past, and it is possible those
constraints on PreferredMode still apply for modern X servers. Anyhow, it
is worth a try.
Just as importantly, I've not yet figured out why anyone should have to do
manually (presuming they can even figure out how) what used to work
automatically. For years, no modelines were in xorg.conf were required, and X
just used the first usable entry on the applicable modes line in 'Section
"Screen"'. Later someone decided a PreferredMode entry in 'Section "Monitor"'
was required to perform the same function, but now it no longer works.
Supposedly the overhaul of X begun two years ago was to make
operation/startup/configuration (?more?) automatic, not less, but I, always
using Trinitron CRTs, have only observed quite the contrary so far. X for me
has regressed from the jet age back to piston engined biplanes without
electric starters.
Like you, I hope the Intel jet age comes back soon.
By the way, my 15-year old Trinitron finally gave up the ghost earlier this
year and I replaced it with an LED-backlit ASUS LCD for $130. That was a
superb deal, and I can say that new monitor is better in all respects
(brightness, colours, resolution, and size) except for width of viewing
angle. However, I doubt very much it will last as long as Trinitrons do; the
Trinitrons are not that much worse in quality; and "use it up, wear it out"
philosophy helps the environment (and the bank balance). Thus, I am hanging
on to my remaining 10-yr old Trinitron monitor until it also dies. That
particular monitor is attached to a computer with SIS video chipset (ugh),
but when that computer fails I won't replace it with Intel unless
PreferredMode works properly. So I hope my suggestion above works for you,
but if not, I hope the Intel developers get PreferredMode working
properly again.
