GNU Screen is a free virtual terminal multiplexer that allows a user to access multiple separate terminal sessions inside a single terminal window or remote terminal session. Persistence Similar to VNC, GNU Screen allows the user to start applications from one computer, and then reconnect from a different computer and continue using the same application without having to restart it. This makes migration between locations like work and home simple. Screen provides terminal-agnostic functionality so that users can disconnect and reconnect using different terminal types, allowing applications to continue running without being aware of the change in terminals. Multiple windows Multiple terminal sessions can be created, each of which usually runs a single application. The windows are numbered, and the user can use the keyboard to switch between them. Some GUI terminal emulators provide tabs or otherwise similar functionality to this. Each window has its own scroll-back buffer, so that out...

10.1 Naming Windows (Titles) You can customize each window's name in the window display by setting it with one of the title commands. Normally the name displayed is the actual command name of the program created in the window. However, it is sometimes useful to distinguish various programs of the same name or to change the name on-the-fly to reflect the current state of the window. The default name for all shell windows can be set with the shelltitle command. You can specify the name you want for a window with the `-t' option to the screen command when the window is created. To change the name after the window has been created you can use the title-string escape-sequence (ESC k name ESC \) and the title command (C-a A). The former can be output from an application to control the window's name under software control, and the latter will prompt for a name when typed. You can also bind predefined names to keys with the title command to set things quickly without prompting. 1...

Some people, after installing Ubuntu Linux, see the decision of the startup screen (boot GUI) is not appropriate for the resolution of the monitor set in the system. Here I'll show you a way to correct the usplash resolution to match the set in the system. 1. Open a terminal and type: sudo gedit /etc/usplash.conf The sudo command will ask for your password so you can edit the file with administrator permissions. Usplash.conf to open the file you'll see something like this: # Configuration file Usplash # These parameters will only apply after running update-initramfs. Xres = 640 Yres = 480 Or maybe just: # Configuration file Usplash # These parameters will only apply after running update-initramfs. 2. Sets Xres and Yres the resolution you want, for example 1024 × 768. # Configuration file Usplash # These parameters will only apply after running update-initramfs. Xres = 1024 Yres = 768 And save your changes. 3. Now you must update your initramfs for the cha...
