'm' and 'i' keys suddenly causing odd behavior! [SOLVED]
lazarus / 32-Linux

Hi guys

I have a really weird issue with my Lazarus setup.

I'm using v2.0.4 and Linux Mint 19.3.

All the the alphabetical keys are OK except that when I press the 'i'
key, it causes a tab, and when I press the 'm' key, it causes a new
line carriage return. If I use any other program (text editor,
Libreoffice etc) it is fine, and if I launch a Windows virtual
machine, it is fine in that too. But Lazarus running on my Linux box,
all of a sudden, causes this; never seen it in 10 years of using the
IDE!.

I've tried blowing out the keyboard of crumbs etc! No fix.

Is there something in Lazarus (a setting or something?) that might be
causing this that I have perhaps enabled or changed in error without
realizing?

Thanks a lot

Hi!

Maybe your CTRL key hangs:

CTRL-I = TAB
CTRL-M = Cariage Return

Lift it up with a nail or a scissor???

There's a bugreport about m behaving as Ctrl+m.
So, you're not alone.

It hasn't been solved yet.

This is driving me to madness.

I notice that if I try do a search, every key I press types twice.
e.g. "e" becomes "ee". Yet in the main source code area, it is as
before (everything OK except for "i" and "m"). It is only impacting
Lazarus - no other tool. There has to be something in the settings
causing it or conflicting but I have no idea where to start. I even
tried resetting my keyboard layout to default in Linux Mint system
settings - no avail. :-(

This may be solveable: https://wiki.freepascal.org/Lazarus_Faq#Typing_

However, this may not be connected with the problem with "i" and "m".

I think this was solved in trunk recently.

Your instructions fixed it!

I disabled the IBus thingy and entered the 3 lines into the 2 or 3
files it mentions (creating one or two new files, editing one existing
I think it was) as directed. Rebooted and solved! 'i' and 'm' now
work, and I no longer have double characters for keypresses! Double
bonus!

Thank you sir.

Instead of major surgery why not just hit "a" ("ctrl a" selects all)?
It's probably not mechanical, it's probably a bug. When I had this
problem I went through the whole alphabet and only had problems with
"i" and "m". Here I was just typing characters, and you can see that
the "i" was generating a preceding tab, and "m" was generating a
preceding newline:

Quoteabcdefgh   ijkl
mnopqustuvwxyz1234567890
   ijkl
mjkl
mkl
ml
m

mMMMMMMMIIIIIIII
