Ubuntu20 headless xfce slow response on VNC

cn flag

I have installed Ubuntu20 on intel NUC. I have also installed VNC on it so that I can access this machine at client site from my office. I have to operate it without monitor, so as soon as I unplug hdmi monitor from it, vnc shows it as black screen. So I have installed xfce on it and switched to xfce desktop instead of default ubuntu desktop.

Now I can access it via vnc and no black screen is showing up. But the response is very slow. If I open terminal, it takes 2-3 sec to load and when I type any command it again takes 2-3 sec to show up. It is very slow. How can I make it smooth in operation. Please help. Thanks

Are you sure you installed Ubuntu Core 20? Xubuntu and XFCE are available only in *deb* packages which cannot run on a *snap* only 20 release; but require you to be using a *year.month* or *deb* based normal product not specialist *year* based products.

@guiverc Sorry I didn't get you. I have installed Ubuntu 20.04 desktop and then installed xfce using `apt-get install xfce4`. After that I switched to xfce session

Did you connect to VNC via a local network or via a RealVNC account?

Please correct your question, Ubuntu has had *year* formatted products since 2016 - they are *snap* only and cannot use *deb* packages.

@ArchismanPanigrahi Using realvnc account

@SAndrew RealVNC account can be slow because it transfers the data through their servers. Use a direct VNC connection instead.

@ArchismanPanigrahi Ubuntu is at different location and we are not connected to same network so have to use real vnc

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
