I fiddled with AGPMode and other settings (and did not file a new bug
since nothing helped).
Model: MicroStar MS-7030 motherboard
Host bridge [0600]: nVidia Corporation nForce3 250Gb Host Bridge [10de:00e1]
(rev a1)
01:00.0 VGA compatible controller [0300]: ATI Technologies Inc RV350 AS [Radeon
9550] [1002:4153]
Card Subsystem: Club-3D BV Device [196d:1018]
HW Changes: none known
BIOS: Phoenix 6.00 PG Date: 08/26/2004, has AGP 3.0 Mode Auto/4x/4x8x, tried
all of them.
Disabling DRI with:
---
Section "Module"
Disable "dri"
EndSection
---
and nothing else in xorg.conf obviously works, crashes go away, but the frame
rate of gnome-screensaver module "SkyRocket" of course drops to 2--4seconds per
frame.
With BIOS AGP 3.0 Mode at Auto the driver detects it as 8x, and the
"SkyRocket" module crashes within 10 seconds of its full-screen preview,
when it is firing the first fireworks rocket... :-)
With:
---
Section "Device"
Option "AGPMode" "4"
EndSection
---
as the only contents of xorg.conf, "SkyRocket" module still crashes in the
same way and as quickly.
Slower AGPModes (2, 1) are rejected by the driver with this card.
With:
---
Section "Device"
Option "BusType" "PCI"
Option "AGPMode" "1"
EndSection
---
the crash stays essentially the same, maybe it lives longer for a second or two.
The above were repeated with Devie/Monitor/Screen sections added so that
'Virtual 1920 1080' can be defined; the driver defaults to:
---
(II) RADEON(0): Max desktop size set to 2560x1200
(II) RADEON(0): For a larger or smaller max desktop size, add a Virtual line to
your xorg.conf
(II) RADEON(0): If you are having trouble with 3D, reduce the desktop size by
adjusting the Virtual line to your xorg.conf
---
Adjusting the Virtual size makes no difference, still crashes.
I think I'm just going to give up since the user of this machine has
previously used IceWM environment and is not actually expecting any
3D...after switching over to GNOME it was just easy experiment with nice
3D screensavers... I've left the xorg.conf at 'Disable "dri"' so for
example the screensaver modules still "work", albeit slowly.
