After installing nvidia-glx (driver), cinnamon works in standby mode (black screen, there is a message about restarting and only the context menu works. I launch nemo and the browser through the console. They work but without the closing crosses, themes and panels from Cinn. No). Lightdm works fine. I installed the driver in * .run format instead of the glx package, but nothing has changed. Nvidia GT 620M graphics card. There is also a built-in graphics from intel. Restarting cinnamon and deleting settings from the home folder does not help.
