Very recently, maybe within the last two weeks this issue has started cropping up: once maybe every two days or so, the up and down arrow keys simply stop working for a while - I can move the cursor left and right, I can type characters, but I cannot move to the previous and next lines without using the mouse. The issue lasts for a few seconds/minutes and then is gone. I know that's very vague, but it's shown up on maddeningly different platforms:
- While typing in Firefox on the built-in keyboard of a personal laptop running Arch Linux. Nobody else has access to it, and I very rarely bring it to work.
- While typing in IntelliJ IDEA on various external keyboards of at least two work desktops running Fedora 21. The desktops are rotated randomly (because of pair programming) and all have two keyboards attached via a hub.
The only thing I can think of that these have in common is that I use
setxkbmap -device N -layout us -variant dvorak-alt-intl -option compose:caps on the work desktops and my laptop is configured to use this layout by default.
Is this a known issue?
