When dealing with an unstable system, even requesting a change of VC can take a little time, so be a little patient. The above keystroke gives you access to VC 1 through 6. You can request a different VC by pressing CTRL+ALT+F from another VC. Attempting to access another one can give you back control. Linux has multiple VC’s available to you. They are represented on the filesystem as /dev/ttyX. X Window System runs on a Virtual Console ( VC), also referred to as TTY. While it may seem like the root of the User Stack would be X. Remember the stack of programs inside the user stack? Let’s work with this image for a little bit. Sometimes, you will not be so lucky, the system may seem completely dead. Revive a frozen Linux system with virtual consoles (TTY) Xkill kills instantly without questions asked. Xkill works faster than the traditional X icon or right-clicking the window on the taskbar and clicking close. Then you can execute xkill and point the cursor at the defunct window and click it away. If you are lucky, it will popup sooner then later. If you are using a Linux desktop, your first step should be an attempt to use your window manager’s execute command (alt+f2 in Ubuntu) feature. This concept will help newer Linux user understand some of the task we will perform later. You can imagine that list of programs, including the X server, as another stack inside the User Stack. More than likely X server, a window manager and some programs. Somewhere inside the User Stack, you have programs running. We want to find a way to avoid a reboot or at least provide the cleanest reboot possible to avoid corruption.įor the purpose of this article, Linux can be seen as a set of 2 stacks: The Kernel Stack and The User Stack. At this point, we are not looking to save any unsaved work. There are a few tricks with Linux one can attempt in such a case.

Then comes the awful feeling as you push and hold “Power”. Linux is known to be very stable, but even the most stable system can encounter situations that cause it to become unresponsive.
