I have about 5 "post market" devices and only two of them have any support in postmarketOS: Redmi 4x, in which hardware acceleration does not work and I have not been able to run any DE on it and Pixel 4a, in which judging by the pmOS wiki page works just about everything except the most important part of a modern phone - touchscreen
Only if your device is fully supported
