Well, I've come up with a solution that works. At least for now, I don't know, maybe it could potentially damage my installation (that would be a pity).
For those who are interested, here's my solution.
1. Edit the file /etc/default/keyboard so that the XKBOPTIONS include lv3:ralt_switch and misc:typo. Mine looks like this:
Code: Select all
XKBOPTIONS="grp:alt_shift_toggle,lv3:ralt_switch,misc:typo"
2. Place into /usr/share/X11/xkb/symbols directory the file "typo", which inludes Typographic Keyboard Layout by Sergei Stolyarov, which I took from the Kubuntu distribution (you can extract it yourself, download and run a LiveCD, then copy it out of /usr/share/X11/xkb/symbols, I am not allowed to attach it here).
3. Reboot.
It works for me. I can enter symbols like ™ (ralt+t), © (ralt+c), ←(ralt+(), — (ralt+-), etc.
This is the only feature that I missed in my Debian-LXDE installation. Now I'm happy and ready to use it as my primary OS.
I would appreciate any feedback, I'm worried that I could screw up my installation with this setup.
