when scim is installed, can't enter password at unlock prompt

[LogicalDash]

Binary package hint: scim

I'm using Kubuntu Gutsy on a Compaq Presario v3000z laptop.

I installed Japanese support through System Settings -> Regional & Language -> Install New Language, meaning through qt-language-selector. Then I ran im-switch -c, and chose scim as the default input language for locale en_US. (I don't have any other locales installed, since I don't know what they are for.)

I restarted, and SCIM worked fine, I could turn it on and off and enter Japanese text exactly as expected. However, if I closed the lid of my laptop, then opened it again about 30 seconds later and tried to enter my password to unlock the machine, it wouldn't accept keyboard input. The cursor was blinking in the password field, but no matter how many keys I hit, no dingbats would show up, and I wasn't able to unlock the machine.

I can move the mouse around and click the buttons; I can keep using the computer by clicking Switch Session and then Start New Session, although I won't be able to control any of the applications I've opened in the current session.

Oddly, if I hold down one key and wait for the monitor to turn off again, it'll immediately turn back on, and one dingbat will show up in the input field. I won't be able to actually enter my password, but it seems as though I can input one character in this way.

Oddlier still, if I lock the session through the K menu, without closing the screen, everything will work perfectly, and the password field will accept my input. However, if I lock the session in this way and then close the screen, the same problem occurs.

With the input method for en_US set to "default," this problem does not occur, but I can't use SCIM that way.

In bug #66104 somebody reported that it also affects kdesktop_lock and
the symptom is similar to yours. Can you please have a look at that bug
report [1] and try the workarounds mentioned there?

I just tried the second method listed there. It seems to work. Thanks.

Thanks for testing. It's the same bug then, marking as duplicate.
