Is there any possibility to "fix" the monitor settings so that it won't be set back every time I restart the computer with BNC?

Yes, but read on...
Modern linux distros ship with Xorg that queries your monitor's abilities, and then sets everything up for you. The monitor can be asked what it is and what it can do if you have it connected with a VGA cable. The process refers to
EDID .
A BNC connection won't allow this as it is a one-way connection (PC-> monitor and not the other way round), and modern Xorg doesn't generate an
/etc/X11/xorg.conf that contains anything useful. Generally it just says "Everything configured", which annoys me because sometimes it is not, and then it can be difficult to find out
why.
However, if that file exists, Xorg will read it and obey the settings in it.
Your options:
- Use the the
VGA connection. (Why would you want BNC anyway?)
- Find an old copy of
xorg.conf that worked with VGA connection (you have backups lying around?), and copy it to your new machine. Restart X with <CTRL><ALT><BKSP>.
- Search LQ for my
username and
EDID to find ways of getting your monitor's EDID data and saving it to a file. You can then reference this file in
xorg.conf and
xorg will use it.
- If you still have no joy, please post your
/etc/X11/xorg.conf file (in "code" tags,
please) and the specs for your monitor: Screen dimensions in mm or inches, Hfreq, Vfreq, available resolutions etc and we can try doing this by the "old" (but reliable) method.
In a way, it was easier when we just had to keep a list of our monitor's abilities, frequencies etc. and then just entered them into
xorg.conf but many people thought this was "Too Difficult". So now it is all "automatic", and sometimes doesn't work the way we'd like it to. Sigh.
