Let themselves updated in the background regardless of the time today to work SoftWare Updater prompts for software updates, check the number of packages after. Later in the evening the next restart Ubuntu 14.04 when re-entering a start the graphical interface on a black screen, very anxious, not previously encountered. Even have a heavy heart, but if reloading would waste a lot of time.
Later we see Ubuntu has a start-up mode selection
Once inside there are three versions of the kernel can be selected:
Ubuntu, with Linux 3.13.0-24-generic
Ubuntu, with Linux 3.13.0-24-generic (recovery mode)
Ubuntu, with Linux 3.13.0-30-generic
Ubuntu, with Linux 3.13.0-30-generic (recovery mode)
Ubuntu, with Linux 3.13.0-32-generic
Ubuntu, with Linux 3.13.0-32-generic (recovery mode)
I try to turn from high to low version version, the final choice vmlinuz-3.13.0-24-generic finally started to follow normal. Then search the forum was that because of a kernel upgrade kernel upgrade has led not compatible video card, so he entered the high version of the kernel command line mode again follow: m.oschina.net/blog/227134 way to re-install the driver, but it prompted
0 upgraded, 0 newly installed, 0 to remove
It seems the high version of the kernel is temporarily unable to repair Well, if every time you enter ubuntu kernel must choose a lot of trouble, but unfortunately had to uninstall the higher version of the kernel it:
Firstly uname -a view the current kernel version.
$ Uname -a
Linux xianjian-Lenovo-M490 3.13.0-24-generic # 47-Ubuntu SMP Fri May 2 23:30:00 UTC 2014 x86_64 x86_64 x86_64 GNU / Linux
Then use
$ Dpkg --get-selections | grep linux
Check the currently installed kernel.
Then uninstall the version of the kernel can not be used:
sudo apt-get remove linux-image-3.13.0-xx-generic |
