Suddenly, I am not able to use any combination of meta keys. The Alt key is not working at all in my emacs. Can anyone help me on this issue?

A quick workaround is that hitting escape before another key acts as Meta+key_you_pressed. It's better to figure out what's causing the problem but hopefully this helps for the time being.– DasonCommented Dec 12, 2011 at 18:41

@Dason Thanks for the comment. It works, but only once. I have to hit escape every time before any Meta command. Weird. I wish I can find what is causing this.– NeoJiCommented Dec 12, 2011 at 18:54

4Could it be that the terminal window is capturing <key>Alt</key> and attempting to use it to access it's menus (eg: File, Edit, etc..)– drevickoCommented Mar 2, 2012 at 4:16

I fixed this in my Ubuntu Terminal app by going in the menu: Edit -> Keyboard Shortcuts and deselecting the 'Enable menu access keys (such as Alt+F to open the File menu)'.
My VNC server had to be restarted with an extra option -compatiblekbd like this example:
vncserver -geometry 2549x1476 :17 -compatiblekbd
Once I added that and restarted my server, the meta key started working as I expect it to.
Note that -compatiblekbd must come after the display number (e.g. :17) or it is interpreted as an argument to -compatiblekbd.
On Gnome 42.4+ you have a keyboard setting that might be enabled by default for using alternate characters on your keyboard.
Go to:
- Settings
- Keyboard
- Click on the "Alternate Character Key" option
- In the popup, select another alternate character key other than left alt
I choose "Right Menu" since I don't even have a menu key on my keyboard but you can choose anything else besides "Left Alt" which is the key that is used to some shortcuts in Emacs.
I was having trouble using the Meta key in Emacs because of that parameters and now it is working as intended since I changed the alternate character key.
