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. Install / Upgrade Linux Kernel 3.12
