How to troubleshoot a black screen after entering the b…

If you encounter a black screen after entering the boot interface on Linux, there are some common troubleshooting methods you can try:

1. Check the hardware connections: ensure that the connections between the monitor, cables, and computer are functioning properly. You can try unplugging and reinserting the cables, or connecting to another monitor.
2. Enable graphics card drivers: If you have installed proprietary graphics card drivers, try selecting the “recovery mode” or “low resolution” option in the boot interface, which may enable basic graphics card drivers.
3. Update graphics card driver: If you have already installed the graphics card driver but are still experiencing issues, you can try updating the driver to the latest version. This can be done by using the command line in recovery mode or by booting the system using a Live CD/USB.
4. Check kernel parameters: Sometimes, certain kernel parameters may cause black screen issues. You can try editing kernel parameters in the boot interface, such as removing “quiet” and “splash” parameters, to see more boot information.
5. Check the boot options: try selecting other boot options on the boot menu, like repair mode or low resolution mode, to see if you can successfully enter the system. If you can enter the system, you can try resolving the issue by updating software packages or repairing damaged file systems.
6. Check the log files: If the above methods do not solve the problem, you can try to check the system’s log files, such as /var/log/Xorg.0.log and /var/log/syslog, for more information on the black screen issue.

If none of the above methods are able to resolve the issue, it may be necessary to investigate further, such as checking hardware compatibility, upgrading or rolling back kernel versions, etc. In this case, you may need to consult a specific Linux distribution or seek help from the community.
