Screen flicker

Hi all,

I'm new to Zorin but have installed other Linux OS already. Only in Zorin 16 I have the issue that after installation (which went fine) and reboot the screen is flickering on my Laptop whereas on my second external monitor it is fine.

My Laptop is a 1 year old Tuxedo with AMD Ryzen 4700U which has AMD graphics card.

How can I find out that issue to be solved?

Nevertheless Zorin OS is a great system (once it works) ..



Was it after an update of the system?

What kernel are you using?

uname -a

I selected update during install ..

I can see initially a 5.11 kernel was installed too ..

There have been others with your problem, regarding kernel 5.13. Try boot into kernel 5.11 and see if the problem goes away.

Ok, that works.
But does that mean I cannot use newer kernels? In other OS I never had a issue using newer kernels ..

It means there's bugs in kernel 5.13 regarding amd drivers, but maybe solved in future releases.

Hi there. I have similar hardware configuration and I was experiencing same issue. Rather than selecting older kernel, I installed newer one. Mostly because I have quite new hardware. Using kernel with higher version than delivered by zorin is probably not recommended, because it is not tested and can be unstable, but I have not experienced any issue so far. You can install new kernel quite easy for example here:
