Marso" To: freebsd-questions@FreeBSD.ORG Subject: Trident 9685 chipset linear addressing Message-ID: <19981021100755.A22179@marso.com> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii X-Mailer: Mutt 0.94.13i Sender: owner-freebsd-questions@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.ORG I have a Trident ProVideo 9685 PCI bus video card with 4 megs. An SVGA driver card. I can only get 8bpp to work, not 16bpp. If I use 16bpp, X denands that I enable linear addressing (Option "linear" in XF86Config). When I do so, I get a distorted screen, apps start running at molassis speed (about 2 minutes to bring up an auto-running xterm), and "bit_blt engine" errors. I've seen in the XFree docs that NetBSD and OpenBSD have some problems with linear mode addressing connected with certain security defaults in the kernel and the OS. Could this be an issue here, with FreeBSD? (I run a pre-cam 3.0 current, aout). Disabling acceleration doesn't help. And you can't turn off bit_blt for the Trident, as far as I can tell. Does anyone have this Trident card up and running? I'd appreciate looking at your XF86Config and learning about any other adjustments to your FreeBSD configuration that was required.
