Hi, I've been using the 4.15 kernel until now without any problems. Today I updated from 4.15.0-15 to 4.15.0-20, as proposed by the Update Manager (I set it to check for all levels, including 4 & 5). After rebooting, the wifi would not work and Cinnamon showed a message saying that it was running on the software graphics acceleration. So I guess there are drivers that can not be loaded. I tried to reboot twice, same problem. Rebooting with the previous version (4.15.0-15) solved the problem. Is anyone else on the 4.15 kernel? Did you update to 4.15.0-20 and is it working for you? Please help. I did not find the right solution from the Internet. References: - https://forums.linuxmint.com/viewtopic.php?t=269029 Online the Video the Production Studio Thanks!
