I recently bought a Technika Pro LCD22-408 and it isn't properly
detected by Ubuntu, I ran a get-edid and got this:
VBE/DDC service about to be called
Read EDID
Performing real mode VBE call
Interrupt 0x10 ax=0x4f15 bx=0x1 cx=0x0

** Description changed:
Current xorg in Hardy usually autodetects your monitor, it's resolution,
dpi, etc. and everything just magically works. This happens because
modern monitors can be queried for 'EDID' data, that returns all the
necessary info to configure things properly.
Not nVidia-only, I have the same on an Intel-based laptop
(FujitsuSiemens Lifebook S7110).
get-edid and ddcprobe fail, however everything works out of the box... I
discovered this because xdpyinfo reports dpi and screen physical size
incorrectly...

EDID fail
Well, I believe that I've been experiencing the EDID parse failure as my
notebook exhibits ALL of the symptons listed here, limited to one
resolution(fortunately highest native LCD res), ddcprobe EDID fail,
xrandr one res(highest) reported, read-edid and parsing fail as everyone
else's above does.

I'm using x86_64 which doesn't have read_edid (it is i386 and powerpc
only). How is it intended to set up X properly on this architecture?

I have a problem that may or may not be related. I have seen several cases
where X autoconfig does not work correctly, i.e. you only get 640x480 and have
to correct it with displayconfig-gtk. Some of these cases were related to
complete edid failures as described, but I found at least one case

This monitor and video card setup works perfectly in Windows XP Pro.
The monitor worked perfectly with Ubuntu/KDE 6.10 and older versions.
It also works perfectly in all versions of OS X. In all cases the
monitor is using a DVI connection and switching to a VGA adapter did not
correct the problem
I'm also having this problem on my 14 Lenovo Thinkpad T61p (with Nvidia Quadro
FX 570M video card, LCD native resolution is 1400x1050), and since it's a
laptop, I can not get informations like bandwidth/frequencies of the LCD.
Although I did find something that may be interesting: when running
Defalco,
You could manually edit the /etc/X11/xorg.conf file (make a backup of it
first), and add the refresh rate range for your monitor.

I have a Gateway Solo 9500 laptop (from approximately 2001) which has a
1024x768 built-in display, but which is being incorrectly detected as
only capable of 800x600. As it turns out, running ddcprobe does indeed
turn up the edidfail message.
This being a laptop display panel, I'm not sure what
I am still using Feisty Fawn so I don't have any issues running sudo
dpkg-reconfigure xserver-xorg or using nvidia-settings to setup my dual
head setup running 2 seperate screens (it's a Nvidia 6200 with agp and
dvi). Now that I see this is happening, I am scared to upgrade. Please
fix this issue.
I started up a separate bug for my particular monitor/video card combo, and
attached all the information to it. Seemed cleaner than merging it into this
bug--however, if anyone is still monitoring this bug, here's a link to the one

Okay, I read your edit of post.
It may be because I use a VGA (DVI-VGA adapter). Because my monitor
only have VGA, and graphics card only have DVI.

The edidfail is not due to xresprobe but rather due to something
incorrect with how your monitor reports its EDID information to the X
server. Refiling against xorg-server.
Please attach your /var/log/Xorg.0.log, /etc/X11/xorg.conf, and the
output of lspci -vvnn
