Hello all: A week or two ago I posted some stuff about a Compaq I was trying to install Linux on. After a lot of trouble, I was finally successful - installed Mandrake 8.0 with a 2.2 kernel, because 2.4 couldn't handle the IDE chipset. There was a second problem that I didn't fix which I'd like to address now: I couldn't set the screen resolution higher than 800x600, even though I know it goes up to 1024x768 (that's the default resolution in the XP installation that came with the machine.) The problem may be with the video chipset - it's an ATI Rage Mobility U1 - there are a lot of versions of ATI drivers, I can tell you, and not many references on Google to that specific version of Mobility. There isn't a reference to the Mobility U1 in the list of graphics cards in the Mandrake control center. However, I did find something on Google that said the Mobility U1 should use ATI's Radeon M6 driver. Mandrake does have a Radeon card in the list, but whenever I select it and try to change the resolution, it gives me an error that says "screens not found" or something like that. (Mandrake doesn't select the right card by default - it selects 3D Labs Permedia, on which I can't change the resolution either.) I was wondering if I might need to install a radeon kernel module. I did find a "radeon.o" module in the 2.2.19 kernel support on the Mandrake CD. The problem was that when I tried to do an "insmod", it complained about a whole bunch of undefined symbols. I'm not sure how I can find where those symbols are located, and if I do I'm not sure if I'm pursuing the right path. Anyone have a similar experience that could shed some light on this problem?
