Hi all, I was wondering if anyone managed to activate the Kernel Modesetting on a powerpc with a radeon video card, and if yes, what are the instructions. I have an Apple iBook G4 12" mid2005, with a ATI Radeon r300 video card (ATI Technologies Inc M11 NV [FireGL Mobility T2e] (rev 80)), and I did not succeed. What I tried is the following: - add radeon.modeset=1 to the kernel options in the /etc/yaboot.conf file and run ybin -v - ensure that radeon module is loaded soon enough in the boot process by adding radeon in the /etc/modules file I am using Debian unstable, with some packages of experimental. The relevant packages seem to be - linux-image-2.6.32-3-powerpc kernel - libdrm2/libdrm-radeon1 2.4.18-3 - mesa packages 7.7-4 - xserver-xorg-video-radeon 1:6.12.192-1 (built from source package in experimental) Everything seems to go well during the boot process, since I see in the syslog: [drm] radeon kernel modesetting enabled. However, when X loads, it cannot find any dri device in the /dev/ directory, resulting in a X session without any graphic acceleration. Typing glxinfo | grep render yields : direct rendering: Yes OpenGL renderer string: Software Rasterizer In the /var/log/Xorg.0.log, I read : (--) RADEON(0): Chipset: "ATI FireGL Mobility T2e (M11) NV (AGP)" (ChipID = 0x4e56) (--) RADEON(0): Linear framebuffer at 0x0000000098000000 (II) RADEON(0): AGP card detected (WW) RADEON(0): Failed to read PCI ROM!

(the last line repeats with increasing card numbers until 15] (EE) RADEON(0): [dri] RADEONDRIGetVersion failed to open the DRM [dri] Disabling DRI. My xorg.conf file possesses only one section relative to virtual display for a possible second screen. Section "Screen" Identifier "Default Screen" Device "ATI Technologies Inc M11 NV [FireGL Mobility T2e]" Monitor "Color LCD" DefaultDepth 24 SubSection "Display" Virtual 1920 1968 Modes "1024x768" EndSubSection EndSection I do not know what to try next. I have KMS running on an i386 iMac with r500 radeon card. Should I just wait for something to be fixed? Did I miss some points in the configuration? Thanks in advance for your precious advices. Best, Cédric
