I have Linux Mint 19.3 installed on ASUS UX360UAK Laptop. The problem I cannot find a solution even after reading many other posts is that the screen (on the main laptop display or on the external monitor) is going black for a second or two and then back randomly. Doesn't matter if the external monitor is plugged in or not. I didn't find a correlation between the CPU or RAM usage and the flickering.
Thanks for an advice in advance - it's really annoying and the laptop is useless for serious work in this condition.
