Re: VNC connection only available if HDMI output is connected to tv

I don't think the Pi4 and x11vnc live well together. I have the tearing of the screen but in my case I can live with that. I wonder if this could be caused by the 'tuning' of the Pi4 for RealVNC. If it is, then that is very annoying as it would mean changing all my VNC software for RealVNC. I did t...

Re: VNC connection only available if HDMI output is connected to tv

Well, lateral thinking...........................maybe the TV can fix the problem? It appears it can! I have a Panasonic Smart TV with 4 HDMI inputs and ARC. Panny uses Viera Link and it was turned ON!! It seems turning that to 'OFF' stops it automatically connecting to an HDMI input which is 'live'...

Re: VNC connection only available if HDMI output is connected to tv

Sorry if I confused the situation. I missed the fact that x11vnc was stated. My experience is with realVNC and tightvnc, both of which allow a virtual display to be created. I think x11vnc is the exception to this and just copies an existing framebuffer. OK. So the Pi4 is different to previous mode...

I think I need to state the current position and requirement as I for one am getting confused lol I am using a Pi4, I do not want to connect to a tv via HDMI because when I do, the Pi is selected as the default TV screen, not the one previously in use. This pi runs 24/7 and is never looked at via th...

Re: VNC connection only available if HDMI output is connected to tv

My available settings differ from yours. I only see composite selection, nothing else. Do you still have "enable_tvout=1" set? That's probably why. Instead of trying to create a framebuffer for a non-existent HDMI monitor that vnc will share, you can start vnc in virtual mode so that it creates it'...

Re: VNC connection only available if HDMI output is connected to tv

Whilst that is correct** AIUI @makem is not using a RealVNC viewer but, according to the o.p., x11vnc which, IIRC, is not compatible with RealVNC. Where I only need to remotely display one or two GUI apps I sometimes just use a PuTTY SSH connection with X-forwarding enabled and start them from PuTT...

Re: VNC connection only available if HDMI output is connected to tv

Manually setting a resolution in raspi-config should also enable hdmi_force_hotplug=1 option, but the chosen resolution may not be the resolution displayed. Don't know why, but if that happens you can manually configure it in the GUI. Menu > Preferences > Screen Configuration screenresolution.jpg N...

Re: VNC connection only available if HDMI output is connected to tv

I had a quick check if the suggestion by rpdom would do the job and yes, the pi does boot up without hdmi connected but the broken text and some underlining still exists. However, the screen is tiny and I don't have the chance of trying to make it full screen on my laptop at the moment but at least ...

Re: VNC connection only available if HDMI output is connected to tv

Thank you for that explanation. I did try changing the resolution via raspi-config, not for the reason you suggest but because the vnc screen was to small on my monitor. None of the options in raspi-config seemed to give a 'full' screen' view on my laptop (monitor) and for various reasons were unsui...

VNC connection only available if HDMI output is connected to tv

I have a Pi4 which I use headless and connect to it using x11vnc. When I set it up initially the HDMI output was connected to a tv and everything worked correctly. After disconnecting the HDMI cable to use for another Pi I find that if I reboot without the HDMI connected I am unable to connect via V...

No web page streamed sound with Chromium default browser

I am using the Buster on the Pi 4 with the default Chromium 74.0.3729.157 browser and am unable to get sound streamed to a smart tv. Other media sound and video streamed by VLC is fine. I had used the Kweb Suite for another purpose but found it caused vnc disconnections so didn't try that again. I f...

I am using the Raspberry Pi 4 (4GB) with Buster and have installed Kweb Suite (and the update).

The file was an mkv (not sure what codec yet...

Re: VNC with 'real' desktop on TV which loses access to the HDMI signal

I find that disabling hdmi_blanking is not an option in the Pi 4. The HDMI is blanked after (15?) minutes and is one explanation why the TV cannot reconnect. Using ssh I installed xscreensaver to check if I could use that to disable blanking and found that when it opened the TV screen woke up. The p...

Re: How to install efficient VNC on Raspbian

Thanks for your feedback. I've added a note to the README that it only works with virtual mode. Still thinking about adding a way to easily enable Console VNC (actually it's been on my ToDo list for a while). And yes, it's easy (as you discovered), but x11vnc has a super-long man page, some people ...

Re: How to install efficient VNC on Raspbian

[ Not sure why you are messing with the Github stuff? RealVNC (service mode) is already installed in Raspbian and by default mirrors the actual 'real' desktop. You only need to enable VNC using sudo raspi-config then reboot. Use the appropriate RealVNC client from here: https://www.realvnc.com/en/c...

Thank you for your reply. I will post in github issues but to complete this thread: I decided to use x11vnc and within a few minutes with very few 'operations' I had a working 'real' desktop which I could leave and return to later. The only issue (not related to VNC) was the HDMI sound output which ...
