Aha... So, from what you know, is there any possibility (fb, X, X with ATI drivers, anything else) to use the video output (or the second head) of radeon cards under Linux? And have you tried your drivers with 2 cards (one PCI and one AGP)?I haven't tried with 2 cards, no. It's possible to do dual head with XFree.quoted
And in all cases, why is parameter "mode" not working? If I could set 1280x1024-32@60 from Lilo, most of my problems would be solved...I'll check that out. The new module parameter thing isn't that good, I think I'll revive the old stuff for a while.
The following patch restores the setup function so that radeonfb can be given options like other fb drivers. There's also a small typo fix (force_dfp -> panel_yres). ===== drivers/video/fbmem.c 1.71 vs edited =====
