NVIDIA显卡驱动已经支持Linux Kernel 3.12
Linux Kernel 3.12 出来后我就一直跃跃欲试，无奈安装后无法启动图形界面，原因在自己的小破PC的NVIDIA显卡使用其私有驱动，安装时build失败。
公司里的电脑没有私有显卡驱动，倒是一个多星期前就装上了。
以上是废话。11月6日更新的NVIDIA显示驱动331.20终于支持3.12内核了，当然，3.11应该也不在话下。
使用3.12后，最明显的感觉就是电脑快了一些。当然，也有可能是我的心理作用。

Linux Kernel 3.12 Released, Install it in Ubuntu & Linux Mint
Linus Torvalds finally announced Linux Kernel 3.12. Here’re the new features and how to install / upgrade to Kernel 3.12 in Ubuntu 13.10, Ubuntu 12.04, Ubuntu 12.10 and Linux Mint.
Linus Torvalds wrote on the mailing list (read the announcement):
I was vacillating whether to do an rc8 or just cut the final 3.12, but
since the biggest reason to *not* do a final release was not so much
the state of the code, as simply the fact that I’ll be traveling with
very bad internet connection next week, I didn’t really want to delay
the release. Sure, we had a number of driver reverts, and there was an
annoying auto-NUMA memory corruption fix series, but none of it was
really worth delaying 3.12 for.
But the fact that I’m going to be (effectively) off-line next week
means that I’m *not* opening the merge window for 3.13 yet …

What’s New in Linux Kernel 3.12:
- The Radeon open-source kernel graphics driver has improved Dynamic Power Management, but it won’t be until Linux 3.13 where Radeon DPM is enabled by default along with HDMI audio.
- A brand new DRM/KMS driver in the form of the Snapdragon MSM driver written by Rob Clark to go along with his reverse-engineered Freedreno driver for Qualcomm Snapdragon/Adreno graphics.
- Run-time GPU power management so NVIDIA Optimus systems can dynamically power on/off the secondary GPU.
- Experimental DRM render nodes support done by David Herrmann over the summer.
- AMD Berlin APU support as the first APU built upon AMD’s Heterogeneous System Architecture (HSA).
- The EXT4 file-system now supports aggressive extent caching and better recovery capabilities.
- Random F2FS, XFS, and Btrfs file-system improvements. This kernel does deliver on disk improvements.
- zRAM has been promoted out of the staging area of the kernel. ZRAM supports a compressed block device in RAM to avoid paging to disk and is mostly of benefit for systems with limited amounts of system memory.
- Various staging driver updates and sound driver work and other glorious work.

For 64-bit Ubuntu, Linux Mint and alternatives run commands below one by one:
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.12-saucy/linux-headers-3.12.0-031200-generic_3.12.0-031200.201311031935_amd64.deb wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.12-saucy/linux-headers-3.12.0-031200_3.12.0-031200.201311031935_all.deb wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.12-saucy/linux-image-3.12.0-031200-generic_3.12.0-031200.201311031935_amd64.deb
2. For both 32-bit & 64-bit install the Kernel via:
sudo dpkg -i linux-headers-3.12.0-*.deb linux-image-3.12.0-*.deb
Once installed, restart your computer and done.
If for some reason the new kernel does not work properly, run command below to remove Linux Kernel 3.12:
sudo apt-get purge linux-image-3.12.0-* linux-headers-3.12.0-*
