Summary: At this point I have a stable desktop where I don't have to reduce my touch-typing speed by a factor of 20 in order to achieve any text input at all (which is how it was this morning before disabling IBUS in my Language Support preferences).
I think ibus-gtk was already installed by default, and selected (at least that's what shows in the Language Support GUI). However, I don't know how ibus-gtk relates to xim, and the problems between xim and e.g. Inkscape remain unspoken. The assertion that no IM module was installed seems to be an assumption from @happyaron but it's hard to tell if that's what he meant, or why, from his very short comment. However, querying the environment variables by running 'export' in bash you see... declare -x GTK_IM_MODULE="xim" ...both before (when ibus was selected) and after selecting 'none' in the Language Support GUI and logging out and in again. I have no idea where this is coming from, but I suspect it's to do with im-config, given it explicitly exports that environment variable I couldn't find another reference to it in my profile or session files, but I'm not really sure what I'm looking for. I installed SCIM manually, (scim-gtk-immodule) following advice online that running applications with SCIM was a good way to workaround the bug/feature interaction/whatever (no-one seems to want to talk about the actual bug), as described at http://www.inkscapeforum.com/viewtopic.php?f=29&t=18042 which I needed to resolve because of https://bugs.launchpad.net/ubuntu/+source/inkscape/+bug/1385009 IBUS seems to also be related to this serious bug I was also experiencing... https://code.google.com/p/chromium/issues/detail?id=456766 so disabling it seemed like a good idea. Given my keyboard input is all in ASCII (as you'd expect from a en-GB or en-US configured laptop) I fail to see why there's internationalisation support baked into my desktop anyway, especially if it's buggy and prevents so many applications on the desktop from operating. However, so far I would say I have a slim grasp of what the actual bug might be, despite all the reports I've read. So far, only workarounds and buck- passing. Searching the repositories for anything to do with a binary or lib ending xim gives me the following, and neither im-switch or uim-xim are installed... $ apt-file search --regexp 'xim$' cyrus-common: /usr/share/doc/cyrus-common/README.exim cyrus-doc: /usr/share/doc/cyrus-doc/README.exim debian-lan-config: /usr/share/debian-lan-config/fai/config/scripts/MAIL_SERVER/10-exim devscripts: /usr/share/doc/devscripts/examples/forward.exim exim4-daemon-heavy: /usr/sbin/exim exim4-daemon-light: /usr/sbin/exim im-switch: /etc/X11/xinit/xinput.d/default-xim im-switch: /etc/X11/xinit/xinput.d/th-xim logcheck-database: /etc/logcheck/ignore.d.server/sa-exim logwatch: /usr/share/logwatch/scripts/services/exim mlterm-common: /etc/mlterm/xim postgrey: /usr/share/doc/postgrey/README.exim sa-exim: /usr/share/lintian/overrides/sa-exim sks: /etc/sks/forward.exim sks: /usr/share/doc/sks/sampleConfig/debian/forward.exim uim-xim: /usr/bin/uim-xim ** Bug watch added: code.google.com/p/chromium/issues #456766 http://code.google.com/p/chromium/issues/detail?id=456766 -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to im-config in Ubuntu. https://bugs.launchpad.net/bugs/1425510 Title: Default IM configuration causes hangs Status in im-config package in Ubuntu: Invalid Bug description: Certain applications have associated input hangs, where no key input events can be sent which sometimes clear after some time, and in at least one case (Inkscape), this is eliminated by running from Start->Run as follows, hence overriding the declaration of GTK_IM_MODULE in /etc/X11/Xsession.d/70im-config_launch , distributed in im-config... bash -c "unset GTK_IM_MODULE && inkscape" A permanent fix on my machine could be to modify the 70im- config_launch file, or declare an overriding export in some later .rc file. Anyone know where I should make this declaration if not modifying package-maintained files? An alternative solution could be to install scim-gtk-immodule and run... bash -c "export GTK_IM_MODULE=scim && inkscape" See also https://bugs.launchpad.net/ubuntu/+source/inkscape/+bug/1385009 Similar behaviours are experienced with Kupfer - minutes of hang with apparently no input events being passed, followed by (sometimes) unfreezing. I'm running Lubuntu Utopic with LXDE and Compiz (minimal dependencies on GTK), so it's feasible that some component is not properly declared in a dependent package. I can't find whether there is in fact a xim module available and running anywhere on my system. How can I check? Other input issues relating to out-of-order key event delivery to Chrome-based applications are experienced on the same build, but I think this may be an independent bug, ostensibly resolved by declaring IBUS_SYNC_MODE=1 https://code.google.com/p/chromium/issues/detail?id=456766 but thought I should mention as it's kind of in the same subsystem and may be linked. I speculate that there is some missing dependency or bad configuration in the default presentation of IM capabilities, which eventually causes a DBUS timeout or similar, eventually causing a fallback without any international input, but which is functional.
