Delete key not working in terminal

[skurty]

I installed Regolith on an Ubuntu 18.04 and the delete key is not working in the terminal. It's well working in other applications but not in this one.

Does the backspace key work in bash or another shell?
For me it only did not work in st (simple terminal) the default.

If you want to switch it, you could follow https://github.com/regolith-linux/regolith-desktop/wiki/HowTo:-Change-the-default-terminal-from-st-to-gnome-terminal

In addition to @TTBeNnI 's good question, any suggestions on how this issue can be reproduced? What type of keyboard are you using? Any specific region or locale settings?

I am experiencing the same problem. my delete button won’t work in terminal, so currently I use backspace to erase. My machine is kubuntu 18.04 LTS, and installing regolith via ppa.

Same here with Ubuntu 19.10 on ThinkPad T480s, Regolith installed via PPA. The problem seems to occur in st only. Any way we can help?

Need to find a way to root-cause the issue. If anyone is able/willing to compile st from source, that would be a good way to see if it's related to any patches in the Regolith variant...

I have not seen the issue, and I use US keyboard and US locale settings in Ubuntu. If those experiencing the issue have another keyboard layout or locale setting that may also be an issue...

[Filip-K]

I just noticed that the st FAQ has a question called "Why doesn't the Del key work in some programs?". Both solutions cited there work for me, but I still find it strange that for some people it works out of the box. I use a mix of en_US.UTF-8 and en_GB.UTF-8 locale settings, and a US keyboard with a US layout.

Nice find @Filip-K ! @bnsv, @skurty , does this also resolve the issue for you?

FWIW I tried various changes to "Region and Language" in the gnome-control-center trying to reproduce the issue but was unable to find a combination that would reproduce it.

I have this issue as well. gnome-terminal didn't have the issue so switching to that was the quickest solution.

[Filip-K]

Just to wrap it up a bit. I think this is not an issue with Regolith, but a feature of st, as described in their FAQ. If you want to stick with st, the cleanest persistent solution might be to cp /etc/inputrc ~/.inputrc and uncomment set enable-keypad on there.

@Filip-K This did indeed fix the issue for me. Thank you!! ❤️

[bnsv]

@Filip-K Yes right, it turns out not a Regolith issue. When in st, then I enter a tmux session, the delete key works normally. Also if I switched to Konsole (KDE’s terminal) the delete key is just work fine. Thank you.

[kgilmer]

I have added @Filip-K 's fix to the wiki's Troubleshooting page. Thanks again @Filip-K ! Closing issue.

this is still an issue, delete key does not work in bash for ragolith-termianl, entering vim within ragolith-terminal delete works as expected, its only on the bash prompt.

FYI, delete key works for gnome-terminal as expected.
