I'm trying to run debian on an old PowerMac 7600/132 with an Apple Multiple Scan 15 Display and I cannot fix the "screen wrap" problem described in previous posts. This is where the left ~15px are actually being displayed on the right.
I've tried a number or settings in debconf, tried to apply a patch (from a .diff file provided by Michel ?) to fbdev, and exhaustively searched the web.
If someone has this setup (it was pretty common) and has solved this problem, please reply. I'd also be interested to see your debconf file as I've been confused by a number of options (for instance, do i have to specify a monitor or just use generic?).
Thankyou in advance for any help.
