intel i915 driver for ubuntu

Dell XPS 8930用了Intel i915 集成显卡,但是Ubuntu把相应的驱动改成了测试版alpha,必须在启动阶段(grub)加入内核参数: i915.alpha_support=1。具体参考网页https://ubuntuforums.org/showthread.php?t=2377324以及https://www.phoronix.com/scan.php?page=article&item=coffee-uhd-graphics&num=1

如果不安装这个驱动,Ubuntu运行图形界面非常非常慢。

琢磨了半天才搞定,记录下来。什么时候,i915驱动重新回到正式版本,而不是alpha测试,就简单了。

从原帖中摘录如下:

  • Install the latest video drivers:
  • sudo add-apt-repository ppa:oibaf/graphics-drivers
    sudo apt-get update

  • Install and use Grub Customizer to do it:
  • sudo add-apt-repository ppa:danielrichter2007/grub-customizer
    sudo apt update
    sudo apt install grub-customizer

  • Launch grub customizer, go to the General tab, and enter i915.alpha_support=1 under Kernel Parameters.
  • Reboot.
