Interesting; it appears from your dmesg that the nouveau drm driver is loaded, but it's trying to use the -intel driver.
You have both Intel and NVIDIA graphics cards present, it appears there is some confusion on the software's part as to which device to fire up. Is this a hybrid graphics system, or do you have a discrete video card? If you remove the video card does it work properly? ** Summary changed: - [gm45] GPU lockup 43f50eee (EIR: 0x00000010 ESR: 0x00000011 PGTBL_ER: 0x00000001 IPEHR: 0x01000000) + [gm45] GPU lockup (EIR: 0x00000010 ESR: 0x00000011 PGTBL_ER: 0x00000001 IPEHR: 0x01000000) ** Description changed: Binary package hint: xserver-xorg-video-intel Appears just after booting up I can not relate it to any program + + [ 17.544133] page table error + [ 17.544135] PGTBL_ER: 0x00000001 + [ 17.544138] [drm:i915_report_and_clear_eir] *ERROR* EIR stuck: 0x00000010, masking + [ 18.330699] wlan0: authenticate with 1c:af:f7:82:e3:00 (try 1) + [ 18.333124] wlan0: authenticated + [ 18.333164] wlan0: associate with 1c:af:f7:82:e3:00 (try 1) + [ 18.338549] wlan0: RX AssocResp from 1c:af:f7:82:e3:00 (capab=0xc31 status=0 aid=2) + [ 18.338553] wlan0: associated ProblemType: Crash DistroRelease: Ubuntu 11.04 Package: xserver-xorg-video-intel 2:2.14.0-4ubuntu1 ProcVersionSignature: Ubuntu 2.6.38-5.32-generic 2.6.38-rc6 Uname: Linux 2.6.38-5-generic x86_64 Architecture: amd64 Chipset: gm45 Date: Fri Mar 11 21:11:28 2011 DistUpgraded: Log time: 2010-12-09 22:53:29.807930 DistroCodename: natty DistroVariant: ubuntu DumpSignature: 43f50eee (EIR: 0x00000010 ESR: 0x00000011 PGTBL_ER: 0x00000001 IPEHR: 0x01000000) ExecutablePath: /usr/share/apport/apport-gpu-error-intel.py InstallationMedia: Ubuntu 11.04 "Natty Narwhal" - Alpha amd64 (20101114) InterpreterPath: /usr/bin/python2.7 MachineType: ASUSTeK Computer Inc.
