Hello, I just discovered that the DRM drivers have been updated and my 855GM is now supported by i915.ko. If I load the module, the driver attaches: drmsub1: <Intel i852GM/i855GM GMCH> mem 0xe8000000-0xefffffff,0xfaf00000-0xfaf7ffff at device 2.1 on pci0 info: [drm] AGP at 0xf0000000 128MB info: [drm] Initialized i915 1.2.0 20041217 But when I start X.org (xorg-server-6.8.99.903), it says: drmOpenDevice: node name is /dev/dri/card0 drmOpenDevice: open result is -1, (No such file or directory) drmOpenDevice: open result is -1, (No such file or directory) drmOpenDevice: Open failed drmOpenDevice: node name is /dev/dri/card0 drmOpenDevice: open result is -1, (No such file or directory) drmOpenDevice: open result is -1, (No such file or directory) drmOpenDevice: Open failed The problem is easily spotted, as there is only /dev/dri/card1. If I try to symlink card1 to card0, the kernel says: error: [drm:pid890:drm_unlock] *ERROR* Process 890 using kernel context 0 (PID 890 is the X server.) while the X.org log file reports: drmOpenDevice: node name is /dev/dri/card0 drmOpenDevice: open result is 7, (OK) drmOpenDevice: node name is /dev/dri/card0 drmOpenDevice: open result is 7, (OK) drmOpenByBusid: Searching for BusID pci:0000:00:02.0 drmOpenDevice: node name is /dev/dri/card0 drmOpenDevice: open result is 7, (OK) drmOpenByBusid: drmOpenMinor returns 7 drmOpenByBusid: drmGetBusid reports pci:0000:61:00.0 drmOpenDevice: node name is /dev/dri/card1 drmOpenDevice: open result is 7, (OK) drmOpenByBusid: drmOpenMinor returns 7 drmOpenByBusid: drmGetBusid reports pci:0000:61:00.0 ...
