Config file for kernel build
System is Fedora 10 with the following graphics userspace:
xorg-x11-server-common-1.5.3-17.fc10.i386
xorg-x11-server-Xorg-1.5.3-17.fc10.i386
xorg-x11-drv-ati-6.10.0-2.fc10.i386
mesa-dri-drivers-7.2-0.15.fc10.i386
mesa-libOSMesa-7.2-0.15.fc10.i386
mesa-libGL-7.2-0.15.fc10.i386
libdrm-2.4.0-0.21.fc10.i386
xorg.conf is configured for driver "radeon" with:
Section "Device"
Identifier "Videocard0"
Driver "radeon"
Option "AccelMethod" "EXA"
Option "AGPMode" "4"
Option "AGPFastWrite" "on"
Option "AccelDFS" "on"
EndSection
Virtual 1440 1080
lspci of video chipset is:
01:05.0 VGA compatible controller: ATI Technologies Inc RC410 [Radeon Xpress
200] (prog-if 00 [VGA controller])
Subsystem: Intel Corporation Device d600
Flags: bus master, 66MHz, medium devsel, latency 64, IRQ 17
Memory at d8000000 (32-bit, prefetchable) [size=128M]
I/O ports at ee00 [size=256]
Memory at fdef0000 (32-bit, non-prefetchable) [size=64K]
[virtual] Expansion ROM at fde00000 [disabled] [size=128K]
Capabilities: <access denied>
Kernel modules: radeon
BIOS configured for 64 MB VRAM.
With distro kernels kernel-2.6.27.30-170.2.82.fc10.i686 and
kernel-2.6.27.35-170.2.94.fc10.i686, and also with vanilla kernels 2.6.31 and
2.6.31.1, the graphics system works normally with DRI fully enabled.
With recently-released 2.6.32-rc3, the graphical login results in a black
screen and no keyboard response (but keyboard leds do not blink). I have not
yet managed to capture a dmesg output or a xorg log. I will try to produce
those later.
Setting
Option "DRI" "off"
on xorg.conf makes the graphical login show up, but with no compiz or any other
DRM support.
To reproduce:
Install Fedora 10 with latest updates
Compile and install 2.6.32-rc3
Attempt to use graphical login, or otherwise start X with DRI on.
Actual results:
System hang with black screen and unresponsive keyboard.
Expected:
Either 1) DRI works normally as it did on earlier versions, or 2) DRI refuses
to work with too-old userspace but allows X to start without DRI and without
additional configuration.
Build 2009-10-05 on Fedora 10 i386
