You may need to install the xorg dummy driver. I actually had issues where my system appeared to lock up if a screen wasn't connected. Turns out xorg was just throwing up its hands because it couldn't push video frames. Installing the dummy driver fixed it, and now I'm using my PC without a screen.
On Fedora, the package is xorg-x11-drv-dummy. You'll have to find it under Raspbian or whatever you're running.
When I run startxI get an error referring to no screens found.So that may be why Orca is not working.So I wonder if there is something in /boot/boot.txt that I could comment out or uncomment to allow it to be okay without a screen?Glenn----- Original Message -----From: Glenn K0LNYSent: Thursday, July 23, 2020 1:18 PMSubject: Re: [orca-list] Orca On The Raspberry PI 4
Hi,
I am using SSH to try to get Raspbian going on this Raspberry PI 4, 4G of RAM.
It is running Buster.
I am using SSH to get into it.
So I did apt-get update first.
Then I did apt-get install mate-desktop
that seemed to go fine
Then I did
apt-get install gnome-orca
That too seemed to go fine.
I still don't know if it boots to a desktop.
I try the user name and password with no sound and then try calling up Orca in what might be the desktop, but no sound.
In the SSH session, I can get audio with both
speaker-test -c 2
and Pranav suggested I try:
Spd-say "hello"
So I know that I can get audio from the speaker jack.
But normally when Orca is working, I can go into a terminal and do:
espeak "hello"
and it comes back with hello.
This normally works in an SSH session, but it does not, and this is the error I get:
There may be a little at the top, but it ran off the screen, and I will paste the results below, and I am wondering if this is why Orca isn't talking...
