Xubuntu 19.10 - 滑鼠指標黑屏

Xubuntu 19.10 在 Dell Optiplex 755 上運行完美。

唯一的問題是，當我讓電腦無人看管一段時間時，我發現只有黑屏，滑鼠指標可見。否則螢幕上什麼都沒有。

我可以 ctrl-alt-f1 並透過終端登入並重新啟動，然後一切恢復正常。

任何想法？

微星VR600X也有同樣的情況。

臨時修復

要讓系統啟動：

After turning on your PC, hold the right SHIFT key to get to the GRUB bootloader.
Once GRUB is open, press the “e” key to edit the first highlighted entry “Ubuntu”.
Move your cursor down to the line that starts with “linux”, and use the right arrow key to find the section with the words “ro quiet splash”.
Add “nomodeset” after these words.

nomodeset

Feel free to remove “quiet” and “splash” for more verbosity to troubleshoot the boot process.
Press “CTRL + X” or “F10” to boot.
The system should now boot.

永久修復

要永久解決該問題：

Once the system has booted using the temporary fix, log in.
Open a terminal window (Applications -> Terminal, or press the “Start” button and type terminal).
Either “su” in to root, or use “sudo” to open your favorite text editor and edit the file “/etc/default/grub” (I use nano which can be install by running “dnf install nano”):

nano /etc/default/grub

Locate the line with the variable “GRUB_CMDLINE_LINUX_DEFAULT”, and add “nomodeset” to the variables. Feel free to remove “splash” and “quiet” if you’d like text boot. Here’s an example of my line after editing (yours will look different):

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset"

Save the file and exit the text editor (CTRL+X to quit, the press “y” and enter to save).
At the bash prompt, execute the following command to regenerate the grub.conf file on the /boot partition from your new default file:

update-grub

Restart your system, it should now boot!

請注意：在修改任何系統檔案之前，請務必確保您有完整的系統備份！
