What are X resources?

tinyX Window System Frequently Asked Questions (FAQ) List
X clients are typically customizable in their appearance and behavior in a very large number of ways. It would be very cumbersome to require X clients to be called with command-line arguments specifying each of the configurable parameters. Therefore, the X server maintains a database of X resources. When an X client connects to an X server, it inherits a set of properties from the X server that correspond to it.

What is a .emacs file?

FAQ (komplett)
When Emacs starts up it attempts to load, and execute the contents of a file called ".emacs", or "_emacs".

Why does Sendmail ignore /etc/hosts file?

System Management
By default, Sendmail uses DNS for name resolution, not the /etc/hosts file. The behavior can be changed through the use of the /etc/mail/service.switch file. If you wish to query the hosts file before DNS servers, create a /etc/mail/service.switch file which contains the following line: hosts files dns OpenBSD ships with an SSL-ready httpd and RSA libraries.

Why does zsh not work in an Emacs shell mode any more?

Z-Shell Frequently-Asked Questions
Emacs 19.29 or thereabouts stopped using a terminal type of "emacs" in shell buffers, and instead sets it to "dumb". Zsh only kicks in its special I'm-inside-emacs initialization when the terminal type is "emacs". Probably the most reliable way of dealing with this is to look for the environment variable $EMACS, which is set to t in Emacs' shell mode. Putting [[ $EMACS = t ]] && unsetopt zle in your .zshrc should be sufficient.

Why does Emacs say 'Error in init file'?

GNU Emacs FAQ
error occurred while loading either your .emacs file or the system-wide file lisp/default.el. Emacs 21.1 and later pops the *Messages* buffer, and puts there some additional information about the error, to provide some hints for debugging. It may be the case that you need to load some package first, or use a hook that will be evaluated after the package is loaded. A common case of this is explained in Terminal setup code works after Emacs has begun.

Why does Emacs take 20 seconds to visit a file?

GNU Emacs FAQ
Old versions of Emacs (i.e., versions before Emacs 20.x) often encountered this when the master lock file, !!!SuperLock!!!, has been left in the lock directory somehow. Delete it. Mark Meuer says that NeXT NFS has a bug where an exclusive create succeeds but returns an error status. This can cause the same problem. Since Emacs's file locking doesn't work over NFS anyway, the best solution is to recompile Emacs with CLASH_DETECTION undefined.

Where do I put my .emacs, (or _emacs), file?

GNU Emacs FAQ for Windows
Your startup file can be named either _emacs or .emacs, and should be placed in your "home" directory. If you have both files in your home directory, Emacs will load the .emacs file and ignore _emacs. Your home directory is where the HOME configuration variable tells Emacs it is.

Why does XWin.exe ignore the display depth that I pass on the command line?

Cygwin/X Frequently Asked Questions
When running in windowed mode or GDI-based fullscreen mode, XWin.exe must run the X Server at whatever display depth Windows is currently using; in these cases the display depth passed on the command line is ignored. XWin.exe only uses the display depth parameter when running in a DirectDraw-based fullscreen mode, as DirectDraw allows applications to change the display resolution and depth when running in fullscreen mode.

How do I set up a .emacs file properly?

GNU Emacs FAQ
In general, new Emacs users should not have .emacs files, because it causes confusing non-standard behavior. Then they send questions to help-gnu-emacs@gnu.org asking why Emacs isn't behaving as documented. Beginning with version 20.1, Emacs includes the new Customize facility (see Using Customize). This allows users who are unfamiliar with Emacs Lisp to modify their .emacs files in a relatively straightforward way, using menus rather than Lisp code.

How do I debug a .emacs file?

GNU Emacs FAQ
Start Emacs with the '-debug-init' command-line option. This enables the Emacs Lisp debugger before evaluating your .emacs file, and places you in the debugger if something goes wrong. The top line in the trace-back buffer will be the error message, and the second or third line of that buffer will display the Lisp code from your .emacs file that caused the problem. You can also evaluate an individual function or argument to a function in your .

Why does it ignore paragraph parameters?

TeX Frequently Asked Questions - Section 16
When TeX is laying out text, it doesn't work from word to word, or from line to line; the smallest complete unit it formats is the paragraph. The paragraph is laid down in a buffer, as it appears, and isn't touched further until the end-paragraph marker is processed. It's at this point that the paragraph parameters have effect; and it's because of this sequence that one often makes mistakes that lead to the paragraph parameters not doing what one would have hoped (or expected).

How do I get my Emacs key definitions back when running under X?

Apollo FAQ
We have been using Leonard N Zubkoff's (lnz@dandelion.com) Apollo customized versions of GNU Emacs on our Apollos for some time now (latest version we have installed is 18.57). A month ago I started using X. I quickly discovered that all my Apollo function key and keypad key bindings (the gray keys), no longer worked. These bindings were made in my .emacs file using Zubkoff's supplied function, bind-apollo-function-key, which is defined in /gnuemacs/etc/apollo.el.

Do you have a problem with GNU Emacs' C-x' command?

Apollo FAQ
Gnu Emacs 18.55 (with Leonard N. Zubkoff's patches for SR10.2) seems to have a problem with shell subprocesses. At times the 0x0 character (displayed as ^@ by Emacs) appears in buffers running a shell. While this is only a nuisance running an inferior shell, it is a problem when running the M-x compile command: The C-x ' (next-error) function is unable to process the compiler output.
