Package: grub-emu
Version: 2.02+dfsg1-20
Severity: critical
Tags: a11y
Justification: breaks the whole system
Dear Maintainer,
I use Debian with Orca and BRLTTY and executed grub-emu.
When ran on mate-terminal, it shows an interface where BRLTTY displays "Screen not in text mode" and Orca doesn't speak at all.
The only solution to stop it is to killall -9 grub-emu from another terminal.
The most critical situation is when I run grub-emu from a TTY session. In this case, BRLTTY displays again "Screen not in text mode" and my system locked, I was not able to close grub-emu nor to use another TTY to kill it.
The only solution I found to reboot correctly was use SSH.
