From mboxrd@z Thu Jan 1 00:00:00 1970 Date: Mon, 14 Jan 2002 18:33:55 +0100 Subject: Kernel 2.4.x video problems From: Chris Boot To: LinuxPPC Dev , YellowDog Devel Message-ID: Mime-version: 1.0 Content-type: text/plain; charset="US-ASCII" Sender: owner-linuxppc-dev@lists.linuxppc.org List-Id: Hi all, I've got a few questions pertaining to video in recent kernels (2.4.x, x >= 10) on both an iMac DV SE/500 (Summer 2000, ATI Rage 128 Pro) and a G4 Dual 533 (ATI Radeon). First of all, I can only boot the iMac using the novideo kernel argument. If I attempt to use video=aty128fb with or without any vmode parameters, the screen just remains black. I can type blindly and reboot, and got a dmesg. Nothing out of the ordinary. If there are any ways of getting verbose messages from the kernel or the driver itself, I would be rather grateful. Second, the G4/533 works fine with no arguments, but it remains in 640x480, 8-bit color. As soon as I try to get some accelerated video using the Radeon FB driver, the screen remains blank as in the iMac. A dmesg this time does in fact yield a message: "radeonfb: could not claim FB region" or something similar (not by the machine at the moment). Anyone know what's causing this? I can provide full output of either of the dmesg's or lspci's or whatever. Thanks very much, -- .-.
