I have a laptop with a native resolution of 1900x1200 which has been working
fine for the past year an a half.
This weekend I upgraded (which included both X and kde) in unstable/sid and
now I find that my X session is being rendered (according to xvidtune) at
1680x1050
What's odd is that the relevant section from /etc/X11/xorg.conf (pasted below)
wouldn't seem to allow that.
from you're Xorg.0.log below, it is clear the it's trying to get
1920x1200 but can't because all the options it tries are out of
sync.
Thanks for the info. What's odd is that my xorg.conf file is timestamped 2006-10-29 (which is definitely the last time I
intentionally messed with it). And I was definitely getting 1900x1200 before this recent upgrade. So it used to work fine (prior
to the new X packages (7.3+10) being installed).
Anyone know what's going on? The only explanation that makes sense to me
is that Xorg now directly queries the graphics subsystem and essentially
ignores what's been set in xorg.conf. I'm definitely interested in knowing
how to get back the full 1900x1200 resolution.
thanks much in advance,

the rest of your xorg.conf would be helpful.
I've attached it in its entirety.
and here's the relevant part of Xorg.0.log

these generic specs may be the problem. What are the actual hsync and
vrefresh ranges of this monitor? especially for the mode you want?

--------------^^^^^^^^^^^^^^^^^^^^^^^^^^
it can't find a 1920x1200 mode that works. Just as a wild guess, I
would say that the hsync and vrefresh ranges above are not wide enough
to accomodate the mode you want. And sometimes it is possibly just a
rounding error. I have a monitor that is supposed to max out at 86kHz
(note making up numbers here) hsync, but xrandr rounds it to 86.01 and
then fails that mode. I had to spec it to 87kHz in xorg.conf to get it
to operate at it's native resolution.
Thanks for the explanation. I'm still puzzled why my recent upgrade changed things (when my xorg.conf file is still the same).
One would think that both the new and older xserver-xorg packages would round in the same way...
(--) NV(0): Virtual size is 1680x1050 (pitch 1696)
(**) NV(0): Default mode "1680x1050": 147.1 MHz, 65.2 kHz, 60.0 Hz
(II) NV(0): Modeline "1680x1050"x60.0 147.14 1680 1784 1968 2256 1050 1051
1054 1087 (65.2 kHz)
note that this mode sets the hsync at 65.2kHz. It's very possible that
1920x1200 bumps right up against or beyond the 70kHz max you're
using.
So, get the specs of the display and set up your xorg.conf properly.
When I try to use Dell's online system, here's the truncated information available for what's specifically installed (in terms of
the LED screen). Doesn't seem that helpful to me, but maybe someone with expertise can intuit the actual details about what
hardware is being described:
1 PF006 LIQUID CRYSTAL DISPLAY..., 17, WU, VIDEO ELEC. STDS. ASSOC....,
SHARP..., V2
1 RG688 ASSEMBLY..., CABLE..., COAXIAL ..., LIQUID CRYSTAL DISPLAY...,
17, ZANZIBAR/RIKERS/SUVA...
I just went back and found the original invoice (which is much less helpful). That
simply specifies 17" WUXGA display.
I find the read-edid package helpful if you can't get the specs.
Thanks for that. Here's the output of get-edid:

Anyone got any hints on crafting a new xorg.conf file that'll work with my
hardware like the old one used to?
thanks again,
