Problem with keyboard (Lazarus 1.2.6 on Raspberry PI2)
lazarus / 9-Editor

Hi,

I have an annoying problem with pressing some keys on the keyboard
when inside the IDE: strangely it seems that not all keys are
recognized.
The current version of Lazarus is 1.2.6 on a Raspberry PI2.
For example, if I press CAPS-LOCK I would expect all typed keys
written with capital letters but instead no letter appears on the
screen and the cursor remains at the same place blinking.
If I press "ALT GR+[" nothing happens so I have to open another
program (Text Editor for example), type the "[" on the other program
window and then copy-and-paste in the Lazarus IDE.
The problem appears only on Lazarus "Source Editor" window, if I
activate CAPS-LOCK and type on the "Object Inspector" window (for
example into the "caption" textbox of a TLabel) the capital letters
appear as any other character on the keyboard.
Is it a bug of the version 1.2.6 ? Or is it just a setting somewhere
in the editor?
Thank you, regards.


Roberto

Same problem also on a (new) PI3 with Lazarus 1.6 and FPC 3.0.

Check your keyboard layout, Raspbian defaults to en_GB instead of
en_US, where some keys are mapped differently. Use raspi-config to
help.

Thanks for the reply but the keyboard is set to "italian" (I'm
italian) and every key is shown in the other programs (Python editor,
Leafpad etc.).
Today happened another strange thing: I had 3 source file (.pas)
opened of the same project and only in one of them the keyboard seemed
disconnected.
I mean that pressing any key, no character or symbol was visible in
the editor window and the cursor blinked but didn't move.
I had to close the project, replace the file ".pas" from a backup I
had, re-open the project and the keyboard started to "write" again.
It's really a weird problem...

No idea about it then. Could be related to the backend toolkit. As
usual, if GTK doesn't work, try QT. At least Lazarus on Linux has
those two stable and switchable backends.
