VNC has issues when you do not renew/change the screen resolution
rugk opened this issue · 7 comments
we have VNC support (ref. #116) and even docs for it, solving an old question, but there seems to be a big issue with the system resolution:
If you go through the setup as intended (in my case only after enabling direct capture mode and rebooting, though that may be unrelated) you need to go to raspi-config and reset the screen resolution to something non-default.
I seem to be not the only one experiencing this as that workaround has been described here:
https://desertbot.io/blog/headless-raspberry-pi-4-remote-desktop-vnc-setup#step-11-important-change-the-default-screen-resolution
Though as no issue has been reported for this, I'd guess I'll open one here. You can find the full STRs in the blog post there.
That's not a bug - it's actually working as intended. If there is no screen display locally, then VNC has nothing to connect to. In that case you can either use raspi-config as you describe to force the HDMI output to be active, or alternatively run the VNC server in virtual mode.
If you enable "boot to desktop [and autologin]" there is a screen to display – always. As such VNC works.
Also, you only need to apply that workaround once (change the screen resolution) – even if you previously changed that already when connected via HDMI or so. It works flawlessly when you reboot all the next times.
Apart from the reference to #116, which seems irrelevant, what has this got to do with NOOBS?
This is an issue in Raspberry Pi OS rather than NOOBS, so closing.
EDIT: Feel free to create another issue in the docs repo if you believe there are missing details in our documentation.
Hmm okay, so where is the issue tracker for the Raspberry Pi OS?
I found https://github.com/raspberrypi/Raspberry-Pi-OS-64bit, but that only applies to the 64bit version – and, well you onyl offer 64bit now, so hmm??
Issue tracker for the documentation is https://github.com/raspberrypi/documentation/
Issue tracker for Raspberry Pi OS itself is either https://github.com/RPi-Distro/repo or https://github.com/RPi-Distro/pi-gen (unless @XECDesign can suggest somewhere more suitable?)
Okay, moved to RPi-Distro/repo#186
