[BRLTTY] Sometimes single character input on laptop keyboard gives many copies of that character

I do. And you were correct that I did run brltty from within the graphical environment.

I shutdown the graphical environment and switched to only using the linux terminal provided by the kernel with the slowest kbdrate 2.0 cps (delay = 250 ms). The manual doesn’t seem to tell me how to turn it off.

tty1 has my network stuff running
tty2 has sudo brltty -n -r -p hw:0,0
tty3 has vim for testing the issue
tty4 has weechat for testing the issue

With this new setup, the characters double less often. I could not reproduce the problem in vim after I terminated weechat. With weechat open, vim gets maybe 1/1000 characters doubled. In weechat it is more like 1/100 characters get doubled.
The character doubling rate before i changed setups was near 1/10
I will take a look at what is causing this in the code eventually, but it is currently not my top priority.

That sounds frustrating. I’ll try to keep tabs on stuff like that.

In closing, I think you are on to something since it seems dependent on the keyboard rate. I can only assume this is a low priority since this probably does not effect Braille input. I would be curious about the solution if anyone finds out what is going on.
