Can't use VNC [SOLVED!]

Eule · March 11, 2021, 3:18am

There is no option to show the instrument GUI via zynthian.local

With VNC viewer i can access the Zynthian UI, but i don’t need that. I have a touch screen.

noVNC did show it nicely, but only once.
I suspect some sort of security issue.

MrBroccoli · May 4, 2021, 2:48pm

I am still stuck getting the original vnc screen on 5900… can we please get both options on the menu?

riban · May 4, 2021, 7:19pm

What is the feature request reference for this?

MrBroccoli · May 4, 2021, 11:49pm

Please enable vnc:5900 via menu for the main zynthian screen (as well as vnc:5901 for instruments) · Issue #447 · zynthian/zynthian-issue-tracking · GitHub Here!

Many boots ago I enabled VNC server in the web.config. That was not enough to connect with VNC for me. It seems I also had to use raspi-config, which failed the first night I tried it as it could not find libavahi-glibl on the net, but the next morning it found it.

I saw the noVNC connect window one time at that URL, but the connect button would not work. I tried rebooting, now I dont get anything at that url except “Refused to connect”

From the admin screen via the zynth display sized VNC window, going to admin, VNC server is not checkmarked, and it refuses to checkmark…

riban · May 19, 2021, 7:27am

With a fresh install of ZynthianOS 2104, enabling VNC Server in webconf and pressing the Save button then connecting VNC Viewer to zynthian.local:5901 I can see Zynthian’s secondary display:

There is a ticket open requesting another VNC server port be opened to display the main UI which I am looking at.

Will you please explain what ZynthianOS image you have flashed to your Zynthian? What updates you have applied since? Any other info that might impact this? I would expect this to work out of the box like it does for me. If you can reflash the image and start from scratch and it doesn’t work then we can try to trace what external elements are influencing this.

TheGarnet · May 19, 2021, 7:48am

I am restarting with fresh image. Software I am using was downloaded two days ago, stable.

VNC to zynthian.local:5901 does show me the above screen, with the addition of an xterm window.

I am trying to setup headless version. VNC directly to zynthian.local is not working, connection refused. On my image yesterday, raspi-config kept complaining a package was missing when i attempted to enable VNC with it two nights ago. Somehow repeating that step many times, and the package was found. Then i was able to VNC to zynthian.local and get a display that looks like what is shown on the kit, and select different layers, etc. I never had a launch of GUI for any of the synths. Have XQuartz setup on Mac, and other XWindows on Windows and Android, and none of them ever show an xwindow coming up when I ssh -Y, I only get logged into a linux command prompt.

With fresh image tonight, I am getting the same error about missing package when i use the raspi-config instructions I found elsewhere here. Here are my steps;

Flash image from 2021/05/19
VNC does not connect
login to http://zynthian.local
Hardware → Kit → Custom
Hardware → Audio → Soundcard → Rbpi Headphones
Configure internet: System → Wifi → Add Network. (Right now am used wired ethernet.)

Hardware / Display   / Generic HDMI Display 
Hardware / Wiring   / DUMMIES

System → Reboot

webconf:

interface → UI options
enable vnc Server
enable cursor
enable touch widgets

VNC refuses to connect at this point.
From XQuartz xterm → SSH -Y does not launch and xwindow

At Zynthian shell prompt, used raspi-config, UI Options, to enable VNC Server
Rapsi-config gave this message:
Unit vncserver-x11-serviced.service could not be found.
It then proceeded to list 2 packages to upgrafe, and 48 to newly install.

riban · May 19, 2021, 10:11am

Okay so it sounds like your unit is behaving as expected. Feature request 447 covers the enhancement to provide main UI via VNC. This may appear soon… watch this space!

TheGarnet · May 19, 2021, 8:04pm

Thanks for letting me know! OK. Should i be scared of RASPI-CONFIG updating a bunch of packages to install the VNC that does get me the main UI via VNC? Someone else was saying allowing apt-get to upgrade packages is dangerous… If I keep trying raspi-config, eventually it does find the missing file and install it.

I really want to see the gui that would let me tweak synthesizer patches with some of the built in Zynthian synths.

What about the ssh -Y zynthian.local only just giving me a linux command prompt, and not launching an extra xwindow with gui that is supposed to launch their guis if I select a layer with one of those synths?

riban · May 19, 2021, 8:26pm

Until recently we had an issue with apt upgrade breaking Zynthian. Some testing today may have shown this is fixed but until we are sure it is best avoided.

I have dual VNC working nicely on my test unit. I need to finish off the update scripts and UI / webconf integration. I might have done it today had I not been entertaining a fellow Zynthianier. Maybe tomorrow. I was initially quite resistive to VNC but am now pretty happy with its behaviour in Zynthian.

TheGarnet · May 20, 2021, 12:17pm

Sounds like you might be solving one or more of my pain points! Please let me know when I can help test your updates.

riban · May 20, 2021, 12:23pm

I have implemented this in development branches. I will submit a PR today so that the changes can be reviewed, issues resolved and merged into Testing. Let’s hope I did a good enough job for this to happen swiftly

riban · May 22, 2021, 9:41am

Those using the Testing branch may now update and enjoy VNC access to the main UI and the secondary display for engine GUIs. Links to web based VNC access have moved to the “Interface” menu of webconf. VNC ports are 5900 & 5901.

Please test and report success / issues to give us confidence to release in next stable update.

JayBee · May 23, 2021, 4:17pm

I have a raspi3
i downloaded the image today. I activated vncserver in the UI menu and got a vnc screen on port 5901.
then i made software Update, activated testing repositorys and made Softwareupdate again.

Now i got two vnc screens. But on Number one o got a error message.
grafik

Any Idea where to look for a specific Error message?
Which Displaytype to choose?

regards Jens

jofemodo · May 23, 2021, 6:34pm

We need the UI log. You can get it from “webconf->interface->UI log”.

Have you tried “Generic HDMI” ?

Regards,

JayBee · May 23, 2021, 8:18pm

Changed to generic HDMI. Still Error. Here is the Log.

Your problem seems to be this one:

And the solution should be the same

Thanks riban, jofemodo, et al. After failing all day to get the UI’s through X11 on both a Ubuntu system and a Mac , I switched to the test branch in the Web Configuration Tool and updated. Looks like both the Zynthian screen and the individual UI’s are available on a Mac Mini M1 using the built-in VNC app, Screen Sharing. (Enable VNC server on the Zynthian, then Connect to: zynthian.local:5900 then zynthian.local:5901 from the Connection>New menu.) Still too much of a total noob to attest to further functionality, but I’m relieved. There’s a double cursor arrow after I scale the individual UI’s though.

Hi @AndyV

If I connect to either display with VNC Viewer on Windows 10 client I don’t see this issue. Soe viewers allow control over use of local / remote pointer display. You may find an option in the viewer. In Zynthian webconf Interface->UI Options with “Advanced view” enabled there is an option to toggle the cursor on the Zynthian display. Disabling this might help. If you are still stuck with duplicate cursors, some viewers allow manual synchronisation of pointers. I haven’t seen the effect for many years but it used to be a real pain - especially when the wrong cursor was disabled leaving the misaligned one.

Thanks again @riban ,
The options and both ends don’t seem to fix the double cursor in the Mac app, but it doesn’t really matter since the VNC client you’ve clearly added to the webconf tool (as you posted previously and I failed to register) is way niftier anyway. Thanks for, ahem, double pointing me to it.
