Questions tagged [graphics]

graphics is used for questions that are related to graphics mode (tty) as well as graphic cards and their drivers. Please note that there are a few specific tags (like intel-graphics, amd-graphics available that should be used instead when applicable). X11 related issues have their own tag: x11, as do GUI related questions: gui)
