How to resolve the screen flickering issue in CentOS GUI?
If the CentOS graphical user interface appears distorted, you can try the following troubleshooting steps:
- Update your graphics card driver: Using the correct graphics card driver can solve many screen flickering issues in the graphics interface. You can download the latest driver from the official website or the graphics card manufacturer’s website, and follow the installation instructions.
- Adjust resolution: Try lowering the resolution of the graphic interface to reduce the load on the graphics card. You can find the resolution options in the system settings, try selecting a lower resolution.
- Check the hardware connections: Make sure the connection between the monitor and graphics card is correct. Check if the cables are loose or damaged, and reconnect them by plugging and unplugging them again.
- Check for hardware malfunctions: If the above methods are ineffective, it may be caused by hardware malfunctions. You can try replacing the monitor or graphics card to eliminate the possibility of hardware malfunctions.
- Enable software rendering: If the graphics card driver cannot resolve the issue, you can try enabling software rendering. In CentOS, you can enable software rendering by modifying the “/etc/X11/xorg.conf” file.
- Install other desktop environments: If the above methods don’t work, you can try installing other desktop environments like KDE, XFCE, etc., to see if it’s related to the current desktop environment.
- Update your system and software: Make sure that your system and all software are up to date to receive the latest patches and fixes, which could potentially resolve some known graphical interface issues.
If the above methods do not work, it is recommended to contact CentOS technical support or seek help on relevant technical forums.
