G'day Andrew and Alan. According to https://wiki.ubuntu.com/Kernel/LTSEnablementStack if you install the 12.04.0 or 12.04.1 point release and update you will remain on the original Precise stack and not be updated to the Quantal or Raring HWE stacks.
12.04.3 should have the Raring HWE stack with kernel 3.8.x, which should be more performant than the 3.5.x kernel in the Quantal As for removing the HWE stacks, I have not tried to do so but there are some guidelines at http://askubuntu.com/questions/265999/how-to-remove- kernel-lts-enablement-stack fglrx is notoriously bad on linux, so if you need UVD support or better power management (DPM), a better option might be to install the 3.12.6 kernel PPA available at http://http://kernel.ubuntu.com/~kernel- ppa/mainline/ - instructions on how to install and uninstall it are available at https://wiki.ubuntu.com/Kernel/MainlineBuilds -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to fglrx-installer in Ubuntu. https://bugs.launchpad.net/bugs/1058040 Title: fglrx-installer not working with AMD Radeon/Mobility Radeon HD 2000-4000 cards in Quantal To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-release-notes/+bug/1058040/+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
