With a throwaway userid, in a Linux tty (virtual terminal), start Emacs
and create a ~/.emacs containing the single line
(desktop-save-mode 1)
Evaluate this form with C-x C-e.
With .emacs in the current window, visit a new file in a new frame with
C-x 5 C-f asdf <RET>, put some random text into the new buffer and save
it with C-x C-s. Exit Emacs with C-x C-c.
With the same userid, in X Windows, open a terminal and start Emacs (with
no command line arguments). This produces the aforementioned error
messages:
Error (frameset): Font `tty' is not defined [2 times]
Warning (frameset): Attempt to delete the sole visible or iconified frame
. Only one frame is currently open.
Now close this Emacs session with C-x C-c, and attempt to start another
session on the tty. In the *scratch* buffer (apparently) appear the
following error messages:
(emacs:3488): GConf-WARNING **: Client failed to connect to the D-BUS
daemon:
Unable to autolaunch a dbus-daemon without a $DISPLAY for X11
, the pair being repeated 9 times (for a total of twenty messages). Each
one started directly below where the previous one ended (as though a Unix
file was being displayed on a device expecting MS-DOS line terminators).
This Emacs is unusable, some control characters not being interpreted.
For example, on typing M-x, "^[x" gets displayed in the minibuffer
region, and the minibuffer is not active. C-x C-c works, however.
