Ubuntu14.04 restart startup after kernel upgrade black screen Solution

When working today, SoftWareUpdater prompts that software updates are available. After some software packages are checked, it will not be updated on the background. Later, when I restarted at night and went into Ubuntu14.04, the graphic interface was black as soon as I started it. I was very anxious and never met it before. Even the reinstallation has a heart, but if it is reinstalled, it will waste a lot of time. Ubuntu14.04 kernel upgrade detailed steps http://www.linuxidc.com/Linux/2014-05/10

At work today, the SoftWare Updater prompts that SoftWare updates are available. After some SoftWare packages are checked, the SoftWare Updater will update them on the background. Later, when I restarted at night and went into Ubuntu 14.04 again, the graphic interface was black screen as soon as I started it. I was very worried and never met it before. Even the reinstallation has a heart, but if it is reinstalled, it will waste a lot of time.

Ubuntu 14.04 kernel upgrade procedure http://www.linuxidc.com/Linux/2014-05/101240.htm

Later I saw a startup method in Ubuntu:

Three kernel versions can be selected after entering:

Ubuntu, with Linux 3.small-24-generic
Ubuntu, with Linux 3.small-24-generic (recovery mode)
Ubuntu, with Linux 3.small-30-generic
Ubuntu, with Linux 3.small-30-generic (recovery mode)
Ubuntu, with Linux 3.small-32-generic
Ubuntu, with Linux 3.small-32-generic (recovery mode)

I tried from the higher version to the lower version, finally selected the vmlinuz-3.13.0-24-generic finally can follow the normal start. Later, some people in the search forum said that the upgrade of the kernel caused incompatibility of the video card, so they re-enter the kernel command line mode in the later version to re-install the driver in m.oschina.net/blog/227134 mode, but it prompts

0 upgraded, 0 newly installed, 0 to remove

It seems that the kernel of the later version cannot be repaired at the moment. If you have to choose the kernel every time you enter ubuntu, you have to unmount the kernel of the later version:

First, use uname-a to view the current kernel version.

$ Uname-
Linux xianjian-Lenovo-M490 3.small-24-generic # 47-Ubuntu SMP Fri May 2 23:30:00 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

And then use

$ Dpkg -- get-selections | grep linux

View the currently installed kernel.

Then uninstall the unusable kernel version:

Sudo apt-get remove linux-image-3.13.0-xx-generic
