I have the same problem on my HP laptop with Intel Mobile 4 Integrated Graphics Controller [8086:2a42] (rev 07). Tested in current Jaunty and Karmic Alpha 1.
One observation that may be related: the performance problems with the Intel drivers that have been reported elsewhere seem to affect me only when I'm running a kernel with the 64G option and PAE enabled. The "/proc/mtrr fix" (see Bug #314928) helps a lot. When I am running a generic kernel, I don't have any serious performance problems and no need to change /proc/mtrr. -- Kernel High Memory Support 64GB [PAE] incompatible with intel video UXA https://bugs.launchpad.net/bugs/356381 You received this bug notification because you are a member of Ubuntu-X, which is the registrant for xf86-video-intel. _______________________________________________ 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
