Voodoo 3 Resolution Question


I've installed RedHat 8 and am having some problems with my Voodoo 3 3000 PCI video card. It works, but only at 800x600. When I try to change it to 1024x768 I get a blank (black) screen.
What am I missing?

Dunno, I've got a Voodoo3 PCI I use A LOT! What's the /etc/X11/XF86Config-4 file look like? Oh, and what version of XFree did 8.0 ship with? 4.2.1?

Cheers,

XFree86 version 4.2.0 (red Hat Linux release 4.2.0.72)

and XF86Config (there is no -4) for the scren section has:

Subsection "Display"
Depth 16
Modes "800x600" "640x480"
EndSubSection
Subsection "Display"
Depth 24
Modes "800x600" "640x480"
EndSubSection

So the fact that there is no mention of 1024x768 is the problem. Can I just use Vi to edit it. or is there more required than that?

And should I leave it on 16 bit colour, or is 24 ok too? I read somewhere that there was some sort of an issue with 3D rendering and anything other than depth 16?

Yeah, just hand edit the file, no worries. You might want to try to put in a line called: DefaultDepth near the top of the display section, like:

Code:
Section "Screen"
        Identifier "Display Merged"
        Device     "MATROX CARD 1"
        Monitor    "Display Merged"
        DefaultDepth     24
        DefaultFbBPP     32
        Option      "Monitor2Position" "RightOf"
        Option      "MergedFB"
        Option      "MetaModes" "1280x1024-1280x1024 1280x1024 "
        Option      "Monitor2HSync" "31.0-69.0 "
        Option      "Monitor2VRefresh" "50.0-160.0 "
        SubSection "Display"
                Virtual   2560 1024
                Depth     24
                Modes    "1280x1024"
        EndSubSection
EndSection
Hopefully that's not a confusing example, ignore the virtual part, dual-head card... Also, I'm using a voodoo3 with Slack 9 on one machine and I think they made some severe mistakes in the driver as it always caused my machine to go wonko kazoo with XFree86 4.3.0. They added a ton of support for older 3dfx cards so that might have something to do with it. If you upgrade one day and get lots of artifacting and random screen lockups, post back here and I'll show you how to straighten it out, or maybe they'll beat that with XFree 4.3.whatever's next and RH or your next distro of choice will skip 4.3.0.

Cheers,

Finegan
