@nickg: Did you try a higher kernel like 3.5.0.21 (that's what I currently use - http://archive.ubuntu.com/ubuntu/pool/main/l/linux/)? It solved my freeze-problems.
You can get it with a bash script like this: #!/bin/bash #Downloads Ubuntu variants of given kernel in 64-bit flavor KERNELVER="3.5.0-21" KERNELSUB="32" KERNELFLAVOR="_amd64" KERNELCOMMON="_all" SEP="_" mkdir -p /data/shared/packages/Kernel/kernel-$KERNELVER-ubuntu cd /data/shared/packages/Kernel/kernel-$KERNELVER-ubuntu wget http://archive.ubuntu.com/ubuntu/pool/main/l/linux/linux-headers-$KERNELVER$SEP$KERNELVER.$KERNELSUB$KERNELCOMMON.deb wget http://archive.ubuntu.com/ubuntu/pool/main/l/linux/linux-headers-$KERNELVER-generic_$KERNELVER.$KERNELSUB$KERNELFLAVOR.deb wget http://archive.ubuntu.com/ubuntu/pool/main/l/linux/linux-image-$KERNELVER-generic_$KERNELVER.$KERNELSUB$KERNELFLAVOR.deb wget http://archive.ubuntu.com/ubuntu/pool/main/l/linux/linux-image-extra-$KERNELVER-generic_$KERNELVER.$KERNELSUB$KERNELFLAVOR.deb Best regards, Martin. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/993187 Title: ubuntu 12.04 completely freezes frequently.
