iam a big fan of ubuntu. i came back to ubuntu after i used windows 10 for while. i do a clean install of Ubuntu on a core i7 machine with 500 gb SSD and Nvidia Gforce GTX 1050 Ti. after a successfull installation and update, i do restart and the restart took forever and cannot complete. it shows so many strange message. i force to shut down my laptop by pressing the buttun. i turn it back on, and it goes normal. but once i install and open some apps, the ENTIRE system was FREEZING. only mouse moves. i press the Shut down button again. this thinghs happens multiple times that i cannot count it. and i do reinstall again and again, but the exact same problem happens. few months ago before i switched to windows, this annoying thing is the only reason i swithed back to windows. i have tried so many solution i found on Internet, and none of them work. My Laptop was runnig perfectly on windows. but not in Ubuntu. i saw many people got this issue and they find no solution. can anyone please tell me what Happen with Ubuntu?
