Problem with X.org, ATI Radeon X300/X550 Series and TFT LCD SDM-HS73 Sony Monitor
Hi everybody. (Excuse me if my english is not very well.)
I use Debian GNU/Linux Etch, with X.org 7.0.0.
Although the system recognizes my video card and monitor, and
although it seems that all is well configured in the xorg.conf file
(see below), when the X server starts, at first it tries to load a
configuration (horizontal and vertical frequencies) that are out of
the range supported by the monitor (a TFT LCD SDMHS73 Sony Monitor).
I know that because the monitor tells me "Out of scan range", and
shows me the horizontal frequency and the vertical refresh, and I can
see that the vertical refresh is about 84 kHZ, and therefore out of
the range specified in the xorg.conf (see below). Due to that
frequency, seems that either the X server or the video card thinks
that I have a CRT monitor. Can I tell to the X server or the video
card that I have a LCD TFT monitor, and so it must not try that
frequencies (in fact, it only should use the frequencies specified in
the xorg.conf file)?
Well, this is the first attempt to inicialize the X server. When the
monitor reports to the X server (or maybe to the video card?) that
the frequency tried is out of the range it supports, the X server
makes a second attempt and the all works fine. But I don´t like that
the X server (or the video card) try to get a horizontal and vertical
values that are not in the range specified by the xorg.conf file. How
can I get that the X server don`t do this?
By the way, if I comment out the vertical refresh and the horizontal
frequency lines, to get DDC, the same thing happens.
And if I use the vesa driver instead the ati driver, at the first
attemps the X server shows in the monitor strange lines (streaked
lines across the display), and in the second attemp, like with the
ati driver, all works fine (but, like with the frequencies out of
range using the ati driver, I don't like that streaked lines and I
don't want them to appear, because that means that the video card -or
maybe the X server- is sending a signal not supported by the monitor,
isn't it?). But with the vesa driver I can´t change the resolution in
Gnome and KDE (if I try to change the screen resolution, Gnome or KDE
crashes and return me to the gdm -or kdm- start screen).
Thanks in advance for the help.
This is my xorg.conf file. (Note: the ati driver is automatically
selected by X.org when it is configured -by the way, DRI don`t
works-; I commented out this driver and I selected vesa instead
trying to solve the problem, like I explained previously. I also
added the DisplaySize line, because I thought that it could solve the
problem, but that didn't solve it.)
