So we have two endpoints: last known good: 2.6.33.20 first bad: 2.6.34.1
The next step is download the source for both of those into a single git tree (which should be available from Ubuntu) and recompile both checking that we can reproduce the issue when manually compiling the kernel package. Having verified that we can recompile and reproduce the issue at will, we start a "git bisection" to find the offending commit. Something like: $ cd /usr/src/linux $ git bisect good v2.6.33.20 # or whatever the git commit id that corresponds to the Ubuntu kernel is, it should have a tag... $ git bisect bad v2.6.34.1 # git will now pick a point between those two and give you a kernel tree to compile $ make kernel-pkg # install and test and say either $ git bisect good # if the driver loads $ git bisect bad # if vesa is loaded instead # rebuild, reinstall, retest until git pronounces the winner Despite the large number of patches that go into each release, due to the nature of bisection you will only need about 20 recompiles at most, so it is not quite as time consuming as it may first appear! ;-) -- 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/805700 Title: Natty&Oneiric - intel 82945G/GZ graphics card - Intel driver fails To manage notifications about this bug go to: https://bugs.launchpad.net/xserver-xorg-video-intel/+bug/805700/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
