Why is the monitor (DVI adapter) not recognized in Ubuntu 10.10?

Question

linux

There is a machine based on the DH67WW board from Intel. It costs Ubuntu 10.10
When you connect a monitor via a DVI adapter, the system does not see the monitor and, as a result, cannot set the native resolution.
I tried to add a mode through Xrandr, everything seems to be fine and everything works. but before restart. After loading, a mode mapping error for this monitor crashes and everything becomes as it was. Tell me which way to dig

Answer 1

most likely you can’t read the EDID through the adapter and therefore you can’t set the monitor parameters,
try looking for the EDID for your model, or pulling it out of the monitor itself (unfortunately I don’t remember the program) by connecting where the thread is in a regular way.
well, then enter in xorg.conf that a thread like
Option "CustomEDID" "CRT-0: /etc/X11/edid.bin"
PS
for me it solved the problem of connecting the same 2 monitors to ubuntu ... 1 vga and the second through an adapter

Answer 2

I don't know about ubuntu, I use RedHat more. The latest versions of Fedora do not have the xorg.conf file, they also rely on auto-detection, but with a non-standard configuration, you can create it and set the monitor parameters in it.

Answer 3

There was the same problem, but with an atish video card on board, it was decided by installing drivers from the ati website.

Answer 4

I had a problem when it simply turned out that there was no stable contact when connecting, and as a result, auto-detection did not work or worked every other time, and everything was fine-tuned manually through Xrandr, but only until the reboot. For a long time I could not understand what was the matter, I sinned on the driver.
It was decided, as you might guess, by plugging the connector.
