Running any graphical interface applications as root can result in file corruption, especially if the graphical interface application is a text editor. Xauth: file /root/.Xauthority does not exist On coming to command #3, I got this error export DISPLAY=:0.0 # use the value of DISPLAY you've seen 3 lines before.xauth merge ~alien/.Xauthority # use your own username here instead of "alien".sudo -i # or "su -" on older Slackwares.echo $DISPLAY # you'll be needing this value 3 lines below.I found this question with the same error but no solution Unable to launch gedit with sudo I need to have this capability to open files in Gedit as root.

In FIGURE 4.When I run sudo gedit /path/to/some/random/file I get the following error ** (gedit:6262): WARNING **: Command line `dbus-launch -autolaunch=7f8731869e1c690b8205727e0000000a -binary-syntax -close-stderr' exited with non-zero exit status 1: Autolaunch error: X11 initialization failed. This can really help when writing or editing code. As you move the cursor around your JavaScript source, when the cursor is next to any of the following characters, it will match the opening or closing character. Highlight Matching Brackets is a super useful programming feature. When looking at a large JavaScript file, it can be difficult to see the cursor (the blinking block that appears next to letters as you type). Highlight Current Line makes it easier to see where you currently are in the code. It’s useful if you’re writing a letter, essay, or other nonprogramming text, but it can be confusing if turned on while programming. The Enable Text Wrapping setting should be turned off for programming. It’s generally considered good practice to keep lines of code shorter than 80 characters long to help readability, but there will always be exceptions to this rule. It’s only a guide, though, and can be safely ignored. This margin is just a guide to indicate that perhaps your line of code is too long. Gedit will display a faint margin along the right side of the window in column 80. The line numbers appear in the left margin of the window and are not part of your actual code. It’s useful to have gedit display line numbers alongside your code. Once you enable the Side Panel view, it will be displayed the next time you launch gedit.įIGURE 4.5 View preferences View Preferences From the File Browser (Disk Browser in TextWrangler on Mac OS), you can quickly open files, view folder contents, and create new files and subfolders (see FIGURE 4.3). In the bottom of the Side Panel view there is a File Browser tab that you should click to switch to the File Browser. To enable the file browsing view in gedit, choose View > Side Panel to open the Side Panel view. The disk browser is super useful when you want to quickly navigate around your JavaScript folders and files. Most modern programming editors provide a file browsing view where you can see-at a glance-all of your folders and files. If it doesn’t appear in your Start menu, you can search for it by typing gedit in the Start menu’s Search field. Once installed, gedit should appear in your Start menu.
