* How did you enable the sharing? Using the config page: see attached image.
I'm using exactly the same configuration and OS in 3 computers: 2 amd64 and the arm64 Raspberry Pi. In the amd64 ones VNC works. It only fails in the arm64 Raspberry Pi. * The default protocol and suggested one is RDP, did you try if that works better? In my case RDP just doesn't work in any of my machines (neither amd64 nor arm64). The RDP server gives these errors when I try to connect: abr 25 19:06:26 fpglinux gnome-remote-desktop-daemon[4496]: [19:06:26:631] [4496:5565] [WARN][com.winpr.negotiate] - AcceptSecurityContext status SEC_I_CONTINUE_NEEDED [0x00090312] abr 25 19:06:26 fpglinux gnome-remote-desktop-daemon[4496]: [19:06:26:731] [4496:5565] [WARN][com.winpr.negotiate] - AcceptSecurityContext status SEC_I_COMPLETE_NEEDED [0x00090313] abr 25 19:06:26 fpglinux gnome-remote-desktop-daemon[4496]: [19:06:26:731] [4496:5565] [ERROR][com.winpr.sspi.NTLM] - Message Integrity Check (MIC) verification failed! abr 25 19:06:26 fpglinux gnome-remote-desktop-daemon[4496]: [19:06:26:731] [4496:5565] [WARN][com.winpr.sspi] - CompleteAuthToken status SEC_E_MESSAGE_ALTERED [0x8009030F] abr 25 19:06:26 fpglinux gnome-remote-desktop-daemon[4496]: [19:06:26:731] [4496:5565] [WARN][com.freerdp.core.nla] - CompleteAuthToken status SEC_E_MESSAGE_ALTERED [0x8009030F] abr 25 19:06:26 fpglinux gnome-remote-desktop-daemon[4496]: [19:06:26:731] [4496:5565] [ERROR][com.freerdp.core.transport] - client authentication failure abr 25 19:06:26 fpglinux gnome-remote-desktop-daemon[4496]: [19:06:26:731] [4496:5565] [ERROR][com.freerdp.core.peer] - peer_recv_callback: CONNECTION_STATE_INITIAL - rdp_server_accept_nego() fail abr 25 19:06:26 fpglinux gnome-remote-desktop-daemon[4496]: [19:06:26:731] [4496:5565] [ERROR][com.freerdp.core.transport] - transport_check_fds: transport->ReceiveCallback() - -1 abr 25 19:06:26 fpglinux gnome-remote-de[4496]: Unable to check file descriptor, closing connection These errors may be related to this problem that I think is not solved in the Ubuntu current freerdp version: https://github.com/FreeRDP/FreeRDP/issues/7722 ** Bug watch added: freerdp-issues #7722 https://github.com/FreeRDP/FreeRDP/issues/7722 ** Attachment added: "Remote Access config" https://bugs.launchpad.net/ubuntu/+source/gnome-remote-desktop/+bug/1970139/+attachment/5583584/+files/Captura%20desde%202022-04-25%2019-31-43.png -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-remote-desktop in Ubuntu. https://bugs.launchpad.net/bugs/1970139 Title: VNC Connection doesn't work on arm64 (Raspberry Pi 4 8Gb) in Ubuntu 22.04 LTS Status in gnome-remote-desktop package in Ubuntu: Incomplete Bug description: # lsb_release -rd Description: Ubuntu 22.04 LTS Release: 22.04 # apt-cache policy gnome-remote-desktop gnome-remote-desktop: Instalados: 42.0-4ubuntu1 Candidato: 42.0-4ubuntu1 Tabla de versiĆ³n: *** 42.0-4ubuntu1 500 500 http://ports.ubuntu.com/ubuntu-ports jammy/main arm64 Packages 100 /var/lib/dpkg/status # uname -a Linux fpgrpi 5.15.0-1005-raspi #5-Ubuntu SMP PREEMPT Mon Apr 4 12:21:48 UTC 2022 aarch64 aarch64 aarch64 GNU/Linux Summary of the bug: ------------------- When I try to connect to gnome-remote-desktop using VNC to a Raspberry Pi 4 Model B Rev 1.4 (8Gb) under Ubuntu 22.04 LTS the VNC client can't connect (connection is refused). The connection passes the Password check validation but don't connect (sometimes shows screen garbage before disconnecting). I've used several VNC clients (Remmina in Ubuntu and Real VNC in Android) getting the same problem failing either in X11 or Wayland. Notes: - VNC connection does work in in previous Ubuntu 21.10 version with the same architecture (arm64) and same Raspberry Pi. - VNC connection also does work in amd64 machines with Ubuntu 22.04 LTS and gnome-remote-desktop 42.0-4ubuntu1, exactly the same software version that doesn't work on arm64 (Raspberry Pi). There is no apport info at all. Also there is almost no info in the journal regarding this problem.
