I often have to use accents, umlauts, and even sometimes an ogonek. QT apps work just fine. GTK apps used
to work fine. I don't think there was a problem before Slackware 13.0, and though I've seen this problem described elsewhere on the 'net, the solutions seem Gnome-centric and don't work for me.
I set my .Xmodmap file to give me a Compose Key (Multi_key) with ralt and lwin. On my computer, this does the trick:
keycode 108 = Multi_key
keycode 133 = Multi_key
I've also set both ralt and lwin to be compose keys in my xorg.conf:
Option "XkbModel" "pc101"
Option "XkbOptions" "compose:lwin"
Option "XkbOptions" "compose:ralt"
The non-Gnome-centric solutions involve adding to the ~/.gtkrc-2.0 one of the following lines:
Neither of these seem to work for me.
Though the problem seems independent of WM/DE choice (has been present in all I've used), I generally use E16. I have tried removing redundancy (i.e., only setting the Multi_key option in ~/.Xmodmap, or, conversely, only setting it in xorg.conf; or only setting it for ralt or lwin exclusively). Any ideas?
