So, recently I managed to install Zorin OS 16 Pro on an older machine (i7-4790K), and for the most part it's running like a dream.
However, am having an issue with my Radeon HD 5750. Whenever I tried to play any videos on the monitors (2) that are connected to it, the video barely plays. Even Chromium isn't usable on those monitors if Hardware Accelerator is enabled. I've installed glxgears and ran it on these monitors and get 1 frame per second (yes, 1FPS).
Now, I have a 3rd monitor connected to the onboard video, and it works flawlessly and shows 60FPS with glxgears.
I've checked and the Radeon (NOT amdgpu) drivers are installed and the video card is being shown.
I did try to install the drivers from AMD for this card, which was published in 2015 I believe, but get an error about something not being compatible with my X.Org. It needs 1.10 and I have 1.20 installed.
I did check synaptic and everything seems to be up to date
