[Solved] TrIGGERED or tRiggerd - Tr key sequence R is not capitalized

TeknoBilly · 2017-12-08 16:40:44

Here is an odd one.
I'm using a Lenovo ThinkPad X230 with a USB Keyboard. When I type the sequence TR it comes out as Tr. Which was very inconvenient as I was trying to type in a hidden password when I discovered this problem. I switched keyboards to a different brand and style, and it is still happening.

I cannot get this to happen on the Laptop keyboard, only by USB.

Here are some examples:
REALLY
EARLY
TrIGGER
TrUDEAU
TrAIL
LATER
LITER
TrUMP
BETTER
BETROTHED - Why not here
THROUGH
BTrOTHED
ABTrOTHED
BETROTHED
MOTR
CRATER
TRIGGER - paused between T and R

If I use the Caps lock the letters are sent correctly
TRIGGER
TRAIL
BETROTHED
- but if I hold the Shift key down then:
tRigger
tRail
betrothed

Can anyone else recreate this?

I'm using Latest Arch with Cinnamon. This happens in all apps, I discovered in a remote session.
Tried changing keyboards from EN/CA to EN/US and it's still occurring.
I'm not sure where to start debugging this.

Are you using libinput (xf86-input-libinput) or xf86-input-evdev?
Edit: If it is libinput, then maybe your keyboard is sending some strange events for this particular key sequence and it may run in this bug https://bbs.archlinux.org/viewtopic.php?id=232302

Edit: What happens if you try it in a text console without a GUI?

pr0dukter, I have no idea what you are babbling about, but it has no relevance to this thread. Don't hijack: https://wiki.archlinux.org/index.php/Co … _hijacking

Follow up on this issue.
Since the new year, this has not been an issue. Same laptop setup, same USB Keyboard. I have done several updates since I posted this issue and have not experienced any more Keyboard issues.

TRIGGERED TRUMP BETROTHED - the TR sequence now produces the correct results.

I'll chalk it up to the butterfly effect.
Rock on little butterfly
