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.

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,
~c

Here is what part of my xorg.conf looks like:

Section "Monitor"
Identifier "G90f-2"
Option "DPMS"
Option "PreferredMode" "1600x1200"
EndSection

Section "Screen"
Identifier "Default Screen"
Device "ATI RV350 AS [Radeon 9550]"
Monitor "G90f-2"
DefaultDepth 24
SubSection "Display"
#Modes "1600x1200" "1280x1024" "1024x768" "800x600"
EndSubSection
EndSection

As you can see the "modes" are commented out, and monitor
has a "preferredmode". Unfortunately I don't remember what
blog post pointed me in this direction and I don't know what
variant methods might work, if this particular setup do the job.

Hopefully this will be of some .


Cheers,
Kelly Clowers

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.

the rest of your xorg.conf would be ful.

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.

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.

I find the read-edid package ful if you can't get the specs.

Since version 1.3 of the xserver-xorg-core package the configuration file
xorg.conf has more flexibility for multi-head configuration. The different heads
(outputs) of the graphical unit can be bound to different monitor sections via
an option called "Monitor-<ouputname>" in the device section (compare man-page
xorg.conf(5): monitor section). Especially in notebooks, the LCD called LVDS
(search for LVDS in /var/log/Xorg.0.log) is sometimes *not bound* to the monitor
section (and its settings) without this additional option in the device section.
An example configuration (for an intel graphic device but transferable to any
hardware) can be found on http://www.intellinuxgraphics.com/dualhead.html.
Although its an example for a dual-head configuration, it makes clear the
principle of the new option "Monitor-<ouputname>".

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).

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...

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 ful 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 ful). That simply specifies 17" WUXGA display.

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?

I'd start by commenting out the HorizSync and VertRefresh lines above to let
xorg pick it's own instead of being constrained.

also, check Jorg-Volker's idea too. It may be relevant.

Yeah, it looks like there's some good info there, but since I no longer have a problem, I'm less inclined to make sure I
understand it all :-]

thanks to all,

Followup - I found this page:
http://wiki.debian.org/XStrikeForce/HowToRandR12

which mentions dropping the screen/display/modes section
and the vertical and horizontal specs. Further down, it
mentions the use of "preferredmode", although in a more
complex way (with modeline).

P.S. gmail's "update conversation" shows that this is now
redundant, but since I already wrote it, I guess I'll post it.

I'd say this is the problem.
It looks like a bug, so should be reported, but if you remove the Hash # your card should pick up on the first option.
It's obvious that's what you've selected, but transfer to config hasn't been clean, and xserver-xorg has opted for a 'safe' optimal.
