Re: Remote headless Pi4 unresponsive can't reboot

Waoo, SysRq... reminds my youth when I worked with as/400. I'll give a try asap man. I'd like to know if this works as my conf is set to boot to console. So magic there's no way to send this keys sequences from ssh ? Strange behaviour although, it's the first time a linux machine makes this joke to ...

Remote headless Pi4 unresponsive can't reboot

Hi I left my Pi4-4GB working ~ 1 week long. When I came back from school tonight I wanted to go on working with my config but I find the Pi in a nasty status : I can connect with ssh, but no more use VNC server virtual mode which shows a grey screen (I can run it again and use port+1). I can't kill ...

Re: VNC with remmina: desktop cannot be displayed at the moment

Hi Piple I finaly got it. Unfortunately, I won't be able to explain a clean elegant way: I had the idea to fire up my old winXP on which I remembered I had an old RealVNC Client 4.2.9. I tried with it and after some tests and trails I got the Pi desktop using my Unix credentials (I think this is cal...

Re: VNC with remmina: desktop cannot be displayed at the moment

Hi man, thank you for reply The official Raspbian doc says we can connect VNC server with desktop disabled (all in the end of dedicated VNC page), but it is not clear about prereqs for this : RealVNC and/or 3rd party server and/or client.

Re: VNC with remmina: desktop cannot be displayed at the moment

Here is a capture showing the message meaning "Unable to show the Desktop at the moment"
In the output above from vncserver I see something strange to me : the message refers to mypiuser instead of root (I say this because I know that the VNC creds are stored in /root/.vnc/....)
Good night

Re: How can i access my raspberry pi at home from anywhere in the most secure way?

You would have to set only 2 rules in firewalls for this (the less the rules the less resources for this job).

VNC with remmina: desktop cannot be displayed at the moment

Hi Piple I set up my Rasbian Buster (up to date) Pi for remote ssh access with keys only. I'd like I could use it with remmina (3rd party VNC client well known in ubuntu world) so I followed the official doc and downgraded server authentication. This works OK, over ssh too, but only if the pi is boo...
