Hey hey, I just updated my system today and haven't been able to use certain braille display functions. Since the installation date is given as a day in February it could depend on something else.
BRLTTY allows to use a braille display to manipulate the terminal, move the cursor or paste text. These functions don't work anymore. Text can be copied into BRLTTY's buffer, but not pasted, neither can the cursor be summoned to a valid position on the screen.
Does anyone have a reasonable idea what may have caused this?
I have tried this with both the standard Archlinux 6.2.9 kernel and the 6.2.0 realtime kernel.
Could there be a permission issue that forbids BRLTTY to write to the console or permission for USB devices...?
Any hints would be much appreciated!
Best wishes,
Jeanette
It may be related to TIOCSTI restriction which started in linux 6.2, see https://bugs.archlinux.org/task/77745 The fix is to re-enable TIOCSTI with sysctl (for current boot only): sysctl -w dev.tty.legacy_tiocsti=1 You can read how to make it permanent here: https://wiki.archlinux.org/title/Sysctl Jordan
