This article mainly introduces "how to solve the login dead cycle caused by Ubuntu14.04 update software". In daily operation, I believe many people have doubts about how to solve the login dead cycle caused by Ubuntu14.04 update software. The editor consulted all kinds of materials and sorted out simple and easy-to-use operation methods. I hope it will be helpful for everyone to answer the doubt of "how to solve the login dead cycle caused by Ubuntu14.04 update software". Next, please follow the editor to study!
In the case of unsuccessful search for various methods on the Internet, choose to reinstall the graphics card driver and successfully log in to the graphical interface.
First, you need to download the corresponding NVIDIA graphics card driver on another computer (windows system is also available). If you don't know, you can use the command lspci | grep-I nvidia to check the video card model, the URL is http://www.nvidia.cn/Download/index.aspx?lang=cn, download the .run file, and copy it to the U disk.
Second, insert the copied U disk into the learning machine. Ctrl+Alt+F1 enters tty1 mode. F1 to F6 have 6 character interface modes respectively. F7 is a graphical interface. If your U disk is automatically mounted to the system, you can directly enter / media/user/ to see the files under the U disk. User indicates your current user name. If there is nothing, enter sudo fdisk-l to see if ubuntu recognizes the U disk and see what is displayed. Sda represents the hard disk, and here the U disk is displayed as sde1, and under the dev folder, and then type sudo mount / dev/sde1 / mnt, then the things in the U disk are under the root directory mnt. Here we can find the .run file we downloaded, enter chmod 755 xxxxxx.run and sudo. / xxxxxx.run and find an error, and there will be a prompt:
ERROR: Your appear to be running an X server; Please exit X before installing...
Because when you switch to the tty terminal, the graphical X-server is not turned off (Ctrl+Alt+F7 is still there). The installation of the N card graphics card driver must be completely turned off from the original graphic X-server before it can proceed.
The way to turn off X-server: enter sudo / etc/init.d/lightdm stop, and then execute sudo. / xxxxxx.run to start installing the graphics card driver, which will prompt you to have a driver, whether to continue the installation, choose to continue, then select Install without signing, then select Yes, and finally complete the installation and restart, and then log in to enter the password, thank God, finally entered.
At this point, the study on "how to solve the login dead cycle caused by Ubuntu14.04 update software" is over. I hope to be able to solve everyone's doubts.
