Binary package hint: xserver-xorg-video-intel
On Ubuntu 9.10 upgraded from 9.04 with Intel Corporation 4 Series Chipset Integrated Graphics Controller (rev 03) (recognized by X as (II) intel(0): Integrated Graphics Chipset: Intel(R) G45/G43 ) X fail to start when kernel mode setting is enabled. The related errors reported in logs seem to be:
(EE) intel(0): [drm] Failed to detect GEM. Kernel 2.6.28 required.
(EE) intel(0): Failed to become DRM master.
[...]
(EE) intel(0): failed to get resources: Bad file descriptor
(EE) intel(0): Kernel modesetting setup failed
(II) UnloadModule: "intel"
(EE) Screen(s) found, but none have a usable configuration.
The kernel is the 9.10 default aka 2.6.31-14-generic and I have commented out my whole xorg.conf.
When I disable modesetting with nomodeset kernel boot option, X succeed to start, I login to the machine, but I get OpenGL renderer string: Software Rasterizer from glxinfo, and I observe high cpu usage by X when rendering (e.g. loading a page at firefox). This makes the machine feeling rather sluggish. In the log I can see some (mayby) related warnigns and errors:
(WW) intel(0): libpciaccess reported 0 rom size, guessing 64kB
[...]
(WW) intel(0): DRI2: failed to open drm device
[...]
(EE) intel(0): Failed to initialize kernel memory manager
[...]
(WW) intel(0): drmSetMaster failed: Bad file descriptor
[...]
(WW) intel(0): ESR is 0x00000011, page table error
(WW) intel(0): PGTBL_ER is 0x00100000, CS instruction GTT PTE
(WW) intel(0): PRB0_CTL (0x0001f001) indicates ring buffer enabled
(WW) intel(0): Existing errors found in hardware state.
I attach the outputs of lspci, lshw, Xorg.0.log-when-modeseting for the kernelmodesetting on case and Xorg.0.log-when-no-modeseting for the case kernelmodesetting is switched off. The Xorg.conf is empty (contains only comments) in either case.
