No meu computador arm64 (Ubuntu 20.04) eu estava usando o tightvnc até esta manhã.
Descobri que quando redimensiono a janela ela geralmente fica presa e desconectada.
Já vi isso antes, então lembrei que posso usar o Tigervnc (no passado mudei para o vnc4server, mas minha outra máquina Ubuntu 20.04 está usando o Tigervnc, então decidi mudar para isso).
Eu removi o tightvnc e instalei o Tigervnc.
O .vnc/xstartup é assim:
#!/bin/bash
unset SESSION_MANAGER
unset DBUS_SESSION_BUS_ADDRESS
exec startxfce4
O log vncserver -localhost no :1 -geometry 3840x2160do lado do servidor está connection closed unexpectedlyno lado do cliente é assim (.vnc/n1sdp:1.log)

Não sei qual é o principal problema aqui.
Não tenho certeza se isso é relevante, mas usei a chave aberta SSD da minha outra máquina nesta máquina arm64 para acessar um repositório git.
Alguém poderia me dizer o que há de errado aqui? (Eu encontreihttps://www.hiroom2.com/2018/05/07/ubuntu-1804-xrdp-xfce-en/mas não tenho certeza se isso vai resolver o problema. Tentei até o passo 3 echo "xfce4-session" > ~/.xsession e parei porque quero usar o xfce4)
