vnc server, improper install, link&authen OK, but remote screen BLANK.

nickleke · 2023-01-20 20:35:30

I am using BL-32 bit std. BL desktop (Beryll). The BL native install has menu items: Start VNC Server & Preferences. I also use dconf-editor to setup access password and other parms. When I do "aptitude search vnc vino" on the server PC , these items show up: "v vnc-viewer" "v vnc server" "p x11vnc" "p tightvncserver" "p tigervnc-common" "i vino" "i xtightvncviewer". I installed vino server. It is clear that these 2 are installed: vino and xtightvncviewer.
Why does native software shows menu item "Start VNC Server", even though server is not installed. So far, upon connecting remotely to BL/ vnc server ? , my remote PC viewer confirms a connection and successful authentication, but screen is BLANK. help! >>> which vnc server should i use, and how do I set it up ? I am a bit confused.

I don't use vnc so can't help too much I'm afraid, except to explain the menu items. You can have a look for yourself at the file: /usr/bin/bl-remote-desktop-pipemenu

There we can see:
1) It was last edited in 2016 (not by me) so might need updating?
2) The test for the presence of VNC viewer is:

if type 'xtightvncviewer' &> /dev/null; then...

3) If viewer is not found, then it offers to install 'xtightvncviewer' (which you have).
4) Test for server:

if [[ -x /usr/lib/vino/vino-server ]]; then...

(this file is provided by vino)
5) Packages installed if server not found: 'vino' & 'dconf-editor' (which you also seem to have)

So:

It looks as if the server is installed.

As to why the screen is blank, that will need more googling, or help from someone who has used vnc/vino.

^ Thank you for showing the commands @johnraff.

from original author; I am seeking assistance to alter my approach to remote-desktop : I Did fresh install of BL-Beryl-32Bit ; It appeared to me that the native Bunsen install did not have a pre-installed vnc-flavoured server within. Therefore, I installed the vino-server pakg. Remote viewer succeeds in connecting and password authentication, but remote screen stays blank - (gave up in trying this further). So I wonder if I should remove "vino", and try others: x11vnc ?? tigervnc-common ??

BL does not have a any vnc support by default but you can install a server and client via the menu.
The menu will install 'vino', 'dconf-editor' and 'xtightvncviewer' - all of which you seem to have.
There is no package in Debian called 'vino-server'.
Could it be you have installed some other package which is interfering with the operation of the above three?

One other thought - do you have the server and client software installed the correct way round? ie server on the remote machine, client on the machine with the operator?

Respond to nullglob: Thanks, I am new to BL. I don't know where is the menu to install vnc server and client in the BL menus ? In my recent Beryllium-1 32Bit install it appears as if the server and viewer are pre-installed. Regarding the "Blank-Page" puzzle, when I access the vnc server (on BL) from another Linux Ubuntu-Mate desktop via tigervncviewer, the connection appears to occur, the password authentication is confirmed to be correct, but then I get an error message (prior to occurrence of Blank Page), the error is: "read:Connection reset by peer (104)" ; I suspect this error is a more broad IP-Packet message exchange failure. I wonder if the vnc server on BL is buggy ?. I might try to (over-)install the x11vnc or tigervnc-common & try out these alternates. What do you think of this ?

In the menu you can go to "Utilities > Remote Desktop > Install VNC Server".

Try installing and using xtightvncviewer instead of tigervncviewer on the Ubuntu machine?

Or time to do some web searching, eg:
