[persistent problems of NVIDIA driver] - - /dev/sdax:clean, xxx/xxx files, xxx/xxx blocks - the most complete solution

introduction

In relation to Ubuntu In the learning environment , Bloggers encountered a very thorny problem in the early stage of research , I have tried to find a solution on both Chinese websites and extranets , Realizing that this problem is a magical one , Its difficulty seems to be adaptive , There are a lot of people on the website , They used a completely different approach , But they all solved this problem , And for bloggers , This problem may be more difficult , The significance of this paper is to sort out and summarize all the solutions to this problem , I hope it can save you time .

Introduction to the problem

According to the effect

The display effect of this problem is , Start up ubuntu System time , This message will be displayed on the computer screen in black before entering the system , /dev/sdax：clean,xxx/xxx files,xxx/xxx blocks, among sda The last number is from 1 To 5 Both ,xxx It doesn't matter if some of them are numbers

Question meaning

This problem can be understood from two perspectives ：

• Paper meaning ： That is, there is not enough memory in a storage directory , So the solution is to delete the file , Make the memory meet the requirements .
• The actual meaning ： When the computer starts, it will automatically check whether the memory in the storage directory is insufficient , This is a normal message , Prove that there is no file system error on the computer , If there are no other questions , In fact, this message can be ignored , It can open normally .
• Drive problem ： However , If, as the actual meaning says , It should open normally , The reason why it cannot be opened is NIVIDIA The problem of , Graphics driver error , So we need to start with the graphics card driver .

Storage problems

If it is found in the problem display that the previous number is indeed too large , That is, there is a storage problem , Please use the solution of this title ：

• First step ： Use the shortcut keys to enter debug mode ：Ctrl + alt + F1, Note here that you can try it yourself F1-7, As long as you can access the interface ;
• The second step ： Check the usage of the attached hard disk ：df -h
  
• The third step ： If you can see from the mounting that the memory of a storage directory is full , Some space should be cleared ：

Method of removal 1：

sudo apt-get autoremove// Uninstall all packages that are automatically installed and no longer in use 
sudo apt autoremove --purge snapd
rm -rf /etc/X11/xorg.conf
cp /etc/X11/xorg.conf.failsafe /etc/X11/xorg.conf

Method of removal 2：
find Mount point -size +1G( View the mount point Files larger than a certain size )
Switch to a directory where large files exist , Delete large files rm -rf Directory name
The example shows after deletion , Obviously, the available space under the mount point becomes larger , however / Free space has not changed , At this point, you need to perform the following operations after switching back to the mount point du -h -x --max-depth=1
If the capacity does not change after deletion , You can kill the process that occupies the file , Release space ：lsof -n | grep delete

Graphics card driver problem （ You should also enter command line mode first ）

• Method 1： Unload and reload nvidia drive

cat /proc/driver/nvidia/version
sudo apt remove nvidia-*
sudo apt-get remove --purge nvidia*
sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt-get install --reinstall ubuntu-desktop
sudo service gdm3 status
sudo service gdm3 start
sudo apt update
sudo apt upgrade
apt autoremove
sudo reboot

• Method 2：

sudo apt update
sudo apt-get install aptitude
sudo aptitude install xserver-xorg-video-intel
sudo reboot

• Method 3： Failed to enter command line mode , First select... At startup Advanced Mode entry ubuntu, Select the old kernel version /recovery Pattern , Then enter the terminal interface through the shortcut key

Ubuntu, with Linux 4.13.0-26-generic
Ubuntu, with Linux 4.13.0-26-generic (upstart)
Ubuntu, with Linux 4.13.0-26-generic (recovery mode)
Ubuntu, with Linux 4.10.0-42-generic

• Method 4：GRUB analysis

stay BIOS Guide interface press “Esc” Press the key to enter the selection menu , choice ubuntu, And press “e” Enter edit mode ：

The boot run level is given at the end of the line ,3– Multi user mode , Pure text

Press CTRL+X/F10 Boot system , Enter command line mode
If you want to enter command line mode every time you boot up , You need to do the following ：
take /etc/default/grub File configuration under , take GRUB_CMDLINE_LINUX_DEFAULT In one line, change to "quiet splash 3" Save after exit , Use update-grub Command to regenerate based on these changes /boot Under the GRUB2 The configuration file , Restart to enter the command line mode .

• Method 5： modify grub Guide item

Enter terminal mode ：
sudo gedit /etc/default/grub
find quiet splash And add it later nomodeset
sudo update-grub
If the above command cannot be executed , execute sudo cp /usr/share/grub/default/grub /etc/default/grub

Modify startup file ： The solution here is more complicated , Just give a link to the solution ： Problem solving

• Method 6： Repair display manager gdm3

Enter terminal mode ：
iwconfig <your-wifi-adapter> essid <network-name> key <network-password>

sudo apt update
sudo apt clean
sudo apt autoremove
sudo apt update && sudo apt upgrade
sudo dpkg --configure -a
sudo apt install -f

$ cat /etc/X11/default-display-manager
/usr/sbin/gdm3
sudo apt install gdm3

• Method 7： Open pendulum , Unload the drive directly , The problem disappears

summary

This question is basically about NVIDIA A stubborn problem of graphics card driver , Bloggers have tried all the methods , You can only choose to delete the driver for the time being , Through research, we can find , The problem may be the conflict between the driver version and the kernel version , I hope to find more accurate solutions in the future .
