I am using Ubuntu 20.04. After installing the NVIDIA drivers, when my laptop is idle for sometime, it shows a black screen with an error message at random times, and the fan is running at high speed. Also the laptop gets heated up.
Nvidia Graphics card Geforce MX130. Nvidia driver 470 was installed from additional driver section in ubuntu software updates. Cuda 11 was also installed.
OS kernel version : 5.11.0-38-generic
I am not sure what's causing this. On pressing power button, the operating system gets shut down and works as normal. This same thing can happen at any time if laptop is kept idle for sometime. Here is a photo of the issue:

FYI : Due to severity of the problem, i was forced to reinstall the OS. Now nvidia drivers are not installed. and the above said issue is not there. Wacom graphic tablet has also an issue before. The pointer got hang randomly at times when using. After reinstallation of OS its also working fine. But the problem is I am now using onboard graphics. I can use nvidia driver only after this issue is solved.
