#110 SCIM disables keyboard sometimes

[zohn]

I got SCIM through an Ubuntu system update.
Recently, I began having some problems, where the keyboard seemed to stop working suddenly.
I started typing something and suddenly I can't type anymore, then it works again, etc.
I noticed that the problem disappeared when I quit SCIM using its taskbar icon.

However, when I quit SCIM, I usually also get a KDE error window and any KDE app that I have currently open (usually yakuake) gets killed.

This behaviour has been documented earlier. See [ 1618708 ] Strange behaviour: input turns off suddenly in some apps.
Unfortunately the problem may lie in X rather than SCIM but I don't think that's completely proven yet.

See https://bugs.freedesktop.org/show_bug.cgi?id=7869

A patch for X is available there, but it seems to me to more of a hack than a real fix. I tried it, and I think the behaviour became better, but it is still not completely fixed.

This bug is very annoying unfortunately...

I get a similar problem but it's only in GTK+ apps. I've debugged it and the key press and release are definitely being handled by GDK and then GTK, but somewhere up the chain it gets lost. I completely disabled SCIM and the problem went away. I don't know enough about how SCIM interacts with GTK to debug much further, but if someone could give me some guidance I'd be happy to continue debugging. My GTK bug is open here:

I don't use KDE. Can you verify this is still a problem with the latest scim releases? Do you have skim installed as well?

scim has moved development to github. Seeing that this ticket is unverified I ask you to kindly open a new ticket at https://github.com/scim-im/scim/issues/ if you are still affected by this bug. Thank you.
