Ubuntu login is stuck in the "ubuntu" interface and cannot enter the graphic desktop Solution

Ubuntu login card on the "ubuntu" interface cannot enter the graphic desktop solution after changing the computer (amd ati graphics card) to regain the old love ubuntu, but the high temperature and automatic shutdown of all evil people still crash. The reason why the driver cannot be added to the desktop is that it changes the graphics card driver to an AMD proprietary driver. I think the temperature is too high because the video card driver is incorrect... I encountered an error like this (followed by the error process to write a solution): 1. if the driver is restarted after the driver is changed, "the system is running in low graphic mode" is displayed. 2. to solve this problem, if you unfortunately find "sudo rm/etc/X11/xorg. conf ", congratulations, 90%, you will enter another error:" screen (s) found, but none have a usable configuration "(this error can be seen in/var/log/xorg.0.log) (I believe that anyone reading this article can easily access the command line under any error ); 3. here you can shout: fuk u; then, you should rely on yourself: 1. enter the command line in a google method, and then sudo Xorg: 1-configure to generate an xorg. conf. new /Home/your_account/, the specific path depends on the output information when the file is generated; 2. then sudo cp/home/XX/xorg. conf. new/etc/X11/xorg. conf (retrieve the configuration file xorg. conf); 3. finally, sudo reboot; After restart, well, 99%. Welcome to "ubuntu ". Stuck here. That is, the question mentioned in the title. When you enter the "ubuntu" page, you may have heard a prompt on Dangdang's logon page, which means it is very close to success. The method is as follows: 1. press and hold the power supply to force shutdown, enter the recovery mode, and select the failx or other items to enter the graphic interface. If the screen is black, repeat 1 until entering the graphic interface, however, you are not familiar with the upper and lower taskbar and panel (indicating that the driver is still faulty. now, you can exit the terminal and press ctrl + alt + t to run sudo software-center. 3. after seeing the familiar software management center, you should blame yourself: Don't choose the driver with your own bid. In the attached driver, restore the previous video card driver. 4. No, reboot. Conclusion: 1. There are many driver problems on the linux platform. Do not change them easily. 2. delete system files. Remember sudo cp x. backup. If you do not back up the files, feel angry.
