Ubuntu is out today with 12.04.2 LTS, and (with a new kernel 3.5.0-23). It appears the kernel and xserver-xorg from the 12.10 release have been brought forward to current.
Will this new kernel (ie hardware entitlement stack) work on Mint 13 MATE and/or Cinnamon desktops?
From the release notes:
LTS Hardware Enablement Stack
In an effort to support a wider variety of hardware on an existing LTS release, the 12.04.2 point release will ship with an updated kernel and X stack by default. This newer hardware enablement stack will be comprised of the kernel and X stack from the Quantal 12.10 release. The hardware enablement stack is only intended for use on x86 hardware at this time. Those running virtual or cloud images should not need this newer hardware enablement stack and thus it is recommended they remain on the original Precise stack. To remain on the original Precise stack, there are a few options:
Install from a previous 12.04.0 or 12.04.1 point release and update. The previous 12.04.0 and 12.04.1 releases are archived at http://old-releases.ubuntu.com/
Perform an update or upgrade to Precise from a previous Ubuntu release. Only those installing from the 12.04.2 media will automatically receive a newer hardware enablement stack by default.
Perform a network install using the netboot images rather than the new quantal-netboot images.
Anyone wishing to opt into the hardware enablement stack for Precise may do so by running following command which will install the linux-generic-lts-quantal and xserver-xorg-lts-quantal packages:
sudo apt-get install linux-generic-lts-quantal xserver-xorg-lts-quantal
For anyone interested, the specifics regarding the exact policies and procedures regarding the support, maintenance, and upgrade paths for the hardware enablement stack has been documented at the following location:
