From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

How do I disable some interferring xterm keybinds? (sh.itjust.works)

TL:DR : I just want xterm to not do anything special when I start typing ctrl+shift+u so I can write special character, so I must remove the ctrl+u default keybind.

I'm using xterm on a laptop (no discrete gpu and pretty bad integrated graphics, so gpu-accelerated ones like kitty are counterproductive, and I use i3 so an xorg based one sounds better). I also like using vim.

I'm also using a qwerty keyboard, but sometimes write in French and need accents. I've memorized the codes for those I often need, like ctrl+maj+u+e+9 for é, but it doesn't work in xterm because it executes the ctrl+u keybind (delete previous characters and then types "(" (because it's maj+9).

So, following online guides, I've created a .Xresource file with the following code:

XTerm.VT100.translations: #override \n\
   Ctrl <Key>U: none

And I also added the line

exec xrdb ~/.Xresources

But to no avail, even when restarting the x session or manualy running xrdb ~/.Xresources.

What am I doing wrong?

Um, if your primary use is typing accented letters, why don't you just set a compose key? The character sequences you need to type are much more intuitive, and you don't get this type of problem.

In my case, I have scroll lock (the most useless key on the keyboard) set as a compose key. To get "é", I type scroll lock, then e, then '.

You can set a compose key using setxkbmap, for instance setxkbmap -option compose:sclk. (If scroll lock isn't to your liking, there are a number of other modifier keys that can be used instead—list here, starting around line 810.) You can also specify it permanently using X configuration files, although I don't know the exact method.

Thank you, I'll try. Tho I'd still be interested to by the answer to my original question, since I might want to change other keybinds later...
