Today, I accidentally changed the graphics card driver in Ubuntu. As a result, I disabled the 3D desktop. When I started the 3D desktop again, I re-installed the 3D graphics card driver. However, when the problem occurred, the title bar of the window disappeared. after being tuned for a long time, I had to go online and find the answer. The solution is as follows: Modify/etc/X11/xorg. conf file, add Option "AddARGBGLXVisuals" "True" to Section "Screen"
