On my Ubuntu UNR install, for some reason, I'm only able to switch the input language if I press Shift and then Alt. This is quite the opposite of what usually works -- on Windows and other Ubuntu/other Linux systems -- where I press Alt and then add Shift.

Anyone know why this is?

  • Try more times for both next source and last source and press shift after 1 seconds that you pressed Alt key. it fixed my problem – αғsнιη Oct 28 '14 at 11:54

This is most likely a papercut.

If it's only happening on your netbook, the issue is probably an incorrect keymap. Low-level tools for examining a keyboard include xkeycaps and showkey; this should at least tell you what keycodes are getting generated.

At a guess, you may the Alt key mapped as AltGr or a dead key; in that case the use of Shift first might be modifying it back to an Alt key. If that was the case however you would typically see this behaviour with only the left or right Alt (I've never seen a keymap with two AltGr keys).

  • It's weird, because it was a clean install of 9.10. – Jono Aug 5 '10 at 6:56

Try this:

1. System
2. Preferences
3. Keyboard
4. Layouts (Tab)
5. Options...
6. Key(s) to change layout
7. Change to the key combo you want :D

I otherwise have no idea why it would be in a different order. I can only suggest swapping key combinations and then back to Alt+Shift.

  • Definitely tried that. And it only happens on my netbook, not on my other laptops. It's as if Shift+Alt is a different combination from Alt+Shift. Argh. – Jono Aug 3 '10 at 11:30

Unfortunately, there are a number of long-standing bugs in handling switching between keyboard layout. I, for one, had problem with those in 9.10. For me they were fixed in 10.04. (FYI, this is the bug that bit me.) Perhaps and upgrade to 10.04, which is a stable one after all, might fix this. Alternatively you might use a different key - I use the menu key, which has no use whatever for me.


In my case it seems to be doing this whenever I set any Shift keys to toggle or cancel Caps Lock under the Miscellaneous compatibility options in the Keyboard Preferences (Keyboard Layout Options).
