Hi there,

I updated my xorg-server to the latest version 1.5.3-r6 and now my X11
performance for OpenGL (Mesa 7.3-r1) is bad and has wrong colours (eg.
glxgears).

grep -e "\[drm\]" Xorg.0.log

(II) [drm] DRM interface version 1.3
(II) [drm] DRM open master succeeded.
(II) RADEON(0): [drm] Using the DRM lock SAREA also for drawables.
(II) RADEON(0): [drm] framebuffer handle = 0xc0000000
(II) RADEON(0): [drm] added 1 reserved context for kernel
(II) RADEON(0): [drm] installed DRM signal handler
(II) RADEON(0): [drm] register handle = 0x29000000
(II) RADEON(0): [drm] Added 32 65536 byte vertex/indirect buffers
(II) RADEON(0): [drm] Mapped 32 vertex/indirect buffers
(II) RADEON(0): [drm] failure adding irq handler, there is a device
already using that irq
[drm] falling back to irq-free operation
(II) RADEON(0): [drm] Initialized kernel GART heap manager, 5111808
(II) RADEON(0): [drm] removed 1 reserved context for kernel

grep -e "^(EE)" Xorg.0.log

(EE) Failed to load module "fbdev" (module does not exist, 0)
(EE) Failed to load module "vesa" (module does not exist, 0)
(EE) AIGLX error: drmOpenOnce failed (Operation not permitted)
(EE) AIGLX: reverting to software rendering
(EE) PreInit returned NULL for "MOSIC      SPEED-LINK Competition Pro"
(EE) config/hal: NewInputDeviceRequest failed
(EE) PreInit returned NULL for "MOSIC      USB 2A4K  GamePad"
(EE) config/hal: NewInputDeviceRequest failed

It seems to be a problem with AIGLX (drmOpenOnce failed). But I have

Section "DRI"
        Mode 0666
EndSection

and

Option  "BusType"       "PCI"

in my xorg.conf

Does anybody have a suggestion?

Thanks for any help
Johannes
