This seems to be a common question in the forms, but I can't find an answer to my specific issue, and on my level of understanding.
First I'm ignorant of Linux on a whole. I'm learning as I go.
Problem:
I have installed (successfully) Ubuntu 10.04 ppc on my powerpc g4 mac. 400mhz, 1g ram. Its the blue model. It works great, but it does not detect my monitor, and I can not change the settings past 800 X 600. I am using a Dell 19 inch monitor. Analog input (not DVI yet) resolution 12080 x 1024 60hz.
I believe I need to change the info in the xconfig file (but I don't know to what or how), and I may not be saying thta correctly.
Please help, thanks.
