Bug Description
From dmesg:
[ 0.000000] ACPI Error: A valid RSDP was not found 20090521 tbxfroot-219
It seems this ACPI error leads the acpi/video.ko driver to fail to load, which causes the drm driver to fail to load.
Original description:
I'm currently posting this using the vesa driver since -intel is too excruciatingly slow. The /var/log/
Anyways, the symptoms while using -intel are that everything becomes excruciatingly slow while Xorg eats up all available CPU.
Looking at the log I believe this to be the cause of failure:
drmOpenDevice: node name is /dev/dri/card0
[drm] failed to load kernel module "i915"
(EE) intel(0): [drm] Failed to open DRM device for : No such file or directory
(EE) intel(0): Failed to become DRM master.
This happens on a beta live CD as well as with a fully-updated 9.10.
I believe that the DRM errors lead to the driver falling back to an extremely slow (slower than vesa) software rasterizer.
