A CRT monitor and an IBM flat monitor are connected to a Matrox G450 adapter. Both monitors display the command line interface. With X running, the monitor on output 1 is active; the monitor on output 2 indicates absence of signal. If the monitors are swapped across the output connectors, output 2 continues to indicate absence of a signal while output 1 works. From that I conclude that the monitors are OK.
* Do the following reports help to localize the problem to the video adapter or to software? * "Failed to get size of gamma for output default"? * Other ideas? Thanks, ...
