I have installed debian linux on my second PC. I have a Nokia monitor
445XiPlus with two video inputs. With a switch at the monitor I can select
the active input. When I installed, I connected the D-SUB cable to the
linux PC and got a usable screen resolution.
Since I need the (longer) cable with D-SUB connector for the main PC I
connected the linux PC now via three BNC connectors. (That's the monitor
side, there is still a D-SUB at the video card.) Unfortunately the X11
server forgot the monitor that it was installed for. Therefore I have an
unacceptable screen resolution of 800x600.
How can I tell the X11 server that is connected to a monitor that supports
up to 1620x1200?
