As usual, I performed software updates through the update manager. I restarted the computer and I do not see the top bar above each window, with which you can move the window, minimize, close or expand. Having climbed the settings, I realized that some window manager was not running.
In the console, I started startx and xinit, but they both answered "user XA, aborting".
In general, I do not know how to be, the windows are small, I barely squeezed my message here. Help me please.
