Fedora 25 with radeon HD4850 x2 and 4 monitors. 2 monitors remain foggy
 

Hello, please forgive my English. I have a singular problem. I was running Fedora 24 with 4 monitors (graphic card radeon HD 4850 x2 4 headed) and all was working correctly. After upgrading to Fedora 25 monitors 3 and 4 stopped working and showed only fog. I searched the web for similar problems but had no luck. The machine is an i7 960 with 32GB ram, Asus motherboard P6X58D Premium, desktop is Gnome. I tried to reinstall from scratch but the problem is still there. When I configure the displays I can see 4 monitors all configured correctly. Did someone heard of a similar problem and how to solve it?

Hello, I know that the problem was not explained well but after all the tests I made I had no clue on witch was the reason of the problem. Yesterday I just upgraded to Fedora 26 and the monitor 3 and 4 are working again. Still now I do not know what was the problem. I like to thank everyone who read the post. Again thank you.
