Question

I have launched emacs (emacs -Q) in the console(Ctrl+Alt+F1). The "left Alt key" is working whereas the "right Alt key" is not working. How to fix the problem. I am running emacs on archlinux

Answer 1

这种行为由你使用的主要布局控制。在您使用的布局中,左带为Meta,而右带为。图表,允许你加入强化特性。 <Change 您的主要布局至不使用右带作为。缩略语

The solution is described here:

It needs some modifications though (see item 3.2 below). Otherwise one would not be able to type anything in current console after the first press of [Right Alt]. If this happened to you, switch to other console (e.g. [Ctrl+Alt+F2]) and restore old keymap.

Here is the brief description of the modified solution:

Save current keymap to file:
dumpkeys >> mykmap
and make a backup of it:
cp mykmap oldkmap
Capture [Right Alt] keycode using showkey command. Let s assume it is 100.
Edit mykmap:
1. Find the corresponding line:
  keycode 100 = AltGr
  and change it to:
  keycode 100 = Alt
2. If the next line (or one of the next lines) is:
  alt keycode 100 = Compose
  remove it.
Load new keymap:
loadkeys mykmap
Make the changes permanent (e.g. add the last command to ~/.bashrc).

Answer 3

There is a workaround. Hit Esc key to activate the alt key as meta in emacs. So a command like M-v becomes Esc M-v
