There is no one official Linux Graphics driver version since the driver is made up of different subsystems like the kernel driver, Mesa 3D driver, and other drivers. Each have their own current release version.
Most Linux-based* distributions already include Intel® Graphics Drivers. These drivers are provided and maintained by the Linux* distribution vendors and not by Intel, we recommend contacting the Linux* Operating System Vendors.
My screen used to flicker too when the Zorin logo appeared....I ignored it that time.....Now it doesn't happen anymore...
Maybe it got fixed when I updated my AMD Drivers.
Updating the drivers also solved other screen problems like the 'white noise' like screen.
Is it just flickering or are there any other issues related to it? Also does it flicker only towards the corners or the whole screen flickers evenly? I asked the second question because my screen used to flicker only towards the lower corners and in the centre the intensity was very low.
