Re: [orca-list] Why feedback of Orca in OS Linux is Annoyingly slower than NVDA in OS Windows? What Should I do for it?

[Rastislav Kish <rastislav kish protonmail com>]

Hello Shadyar,

as for the Orca slowness, aren't you running the system in a VM or from
a linux DVD?

This sounds to me like what I was experiencing when doing the above
mentioned, those slowdowns were happening independently of operating
system run in the VM.


Also, you might want to check out the responsiveness of your keyboard.
Try for example to pause and resume playback of music in VLC, if you
notice the Orca-like latency, you have problem there.

Some distributions have an option to slower the keyboard responsivity,
don't ask me why. :) If you have activated it somehow, that might be
causing troubles.


And one more thing. Some soundcards have a tendency to fall asleep when
no sound is playing. This may not sound like a big thing, but it can
really slow down the whole responsiveness, in some cases even make it
unusable.

One my friend was complaining some time ago, that Jaws on his Windows
machine is very slow. I have installed Silenzio and voila, everything
was magically working!

Try to play some music or other continuous sound in the background to
keep your soundcard busy and try the responsiveness again.

If it improves, we can discuss further in this direction to find the
most appropriate solution.


If nothing of this resolves your issue, and there won't be any ideas
from others on this list, you can, as the last resorrt try to reinstall
the system.

Latency is definitely not something typical for Linux, in fact, it's the
exact opposite and that goes for Orca as well. On my computer, it's
ligthning fast.


As for the Linux environment and its descriptions, well, this is
somewhat complicated. From Windows, you're probably used to having just
one layout, one desktop, one default software setup, dictated by the
all-mighty company behind the system, which doesn't allow anyone to
interfere with its orders.


Linux is different. There is no general authority, no closed components
owned by companies or individuals and no dogmas the system would have to
follow.

Therefore, there is nothing like a single Linux environment. We have
many different environments like Mate, Gnome, Mint, Plasma or LXDE and
every of them has different interface.

In fact, the differences go even deeper, to the core of the system - we
have many Linux distributions, like Debian, Ubuntu, Arch, Fedora or
OpenSUSE, taking different approaches on how should the system look like
"under the hood".


So, as you can see,there is nothing like a single Linux or Linux
environment, and therefore nothing like a single guide and single set of
shortcuts to learn, everything depends on your exact system construction.


Having that said, it's usually not very difficult to find the relevant
instructions, just search for your favourite distribution and check,
what layout it uses and what shortcuts are set by default.

If you want to help others joining Linux by guides, you have the
advantage that you can pick a specific setup and guide the readers on
how to use it, so that's of course a way to go.


Best regards


Rastislav
