Unrelated to the current report, anyway I'll stick to my old Raspbian 32 bits (Buster) since Ubuntu 22.04 currently lacks video hardware acceleration:
https://ubuntuforums.org/showthread.php?t=2478838 ... one of the main uses of my RaspbPi being to watch videos without having run my Desktop PC! So yes, Ubuntu on Raspberry Pi 4 is a nice proof of concept, but there is some work to do to catch up with the Raspeberry Pi OS... and not only on VNC that is so much better integrated on Raspbian. Keep up the good job! -- 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: Fix Released 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 versión: *** 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. When I try to connect to VNC server it show this: On Wayland: ----------- abr 25 00:21:42 fpgrpi kernel: vc4-drm gpu: swiotlb buffer is full (sz: 1884160 bytes), total 32768 (slots), used 3 (slots) abr 25 00:21:42 fpgrpi kernel: vc4-drm gpu: swiotlb buffer is full (sz: 4169728 bytes), total 32768 (slots), used 3 (slots) abr 25 00:21:42 fpgrpi kernel: vc4-drm gpu: swiotlb buffer is full (sz: 8130560 bytes), total 32768 (slots), used 83 (slots) abr 25 00:21:42 fpgrpi kernel: vc4-drm gpu: swiotlb buffer is full (sz: 8294400 bytes), total 32768 (slots), used 3 (slots) abr 25 00:21:42 fpgrpi kernel: vc4-drm gpu: swiotlb buffer is full (sz: 8294400 bytes), total 32768 (slots), used 3 (slots) abr 25 00:21:42 fpgrpi kernel: vc4-drm gpu: swiotlb buffer is full (sz: 8294400 bytes), total 32768 (slots), used 3 (slots) abr 25 00:21:42 fpgrpi kernel: vc4-drm gpu: swiotlb buffer is full (sz: 8294400 bytes), total 32768 (slots), used 3 (slots) abr 25 00:21:43 fpgrpi systemd[1381]: gnome-remote-desktop.service: Main process exited, code=killed, status=11/SEGV abr 25 00:21:43 fpgrpi systemd[1381]: gnome-remote-desktop.service: Failed with result 'signal'. abr 25 00:21:43 fpgrpi gnome-shell[1497]: D-Bus client with active sessions vanished abr 25 00:21:43 fpgrpi systemd[1381]: gnome-remote-desktop.service: Scheduled restart job, restart counter is at 1. abr 25 00:21:43 fpgrpi systemd[1381]: Stopped GNOME Remote Desktop. abr 25 00:21:43 fpgrpi systemd[1381]: Starting GNOME Remote Desktop... abr 25 00:21:43 fpgrpi systemd[1381]: Started GNOME Remote Desktop. abr 25 00:21:43 fpgrpi gnome-remote-desktop-daemon[2125]: Cannot load libcuda.so.1 abr 25 00:21:43 fpgrpi gnome-remote-desktop-daemon[2125]: Cannot load libnvidia-encode.so.1 abr 25 00:21:43 fpgrpi gnome-remote-de[2125]: RDP server started abr 25 00:21:43 fpgrpi gnome-remote-de[2125]: VNC server started On X11: ------- abr 25 00:12:18 fpgrpi systemd[2859]: gnome-remote-desktop.service: Main process exited, code=killed, status=11/SEGV abr 25 00:12:18 fpgrpi gnome-shell[3044]: D-Bus client with active sessions vanished abr 25 00:12:18 fpgrpi systemd[2859]: gnome-remote-desktop.service: Failed with result 'signal'. abr 25 00:12:18 fpgrpi systemd[2859]: gnome-remote-desktop.service: Scheduled restart job, restart counter is at 19. abr 25 00:12:18 fpgrpi systemd[2859]: Stopped GNOME Remote Desktop. abr 25 00:12:18 fpgrpi systemd[2859]: Starting GNOME Remote Desktop... abr 25 00:12:18 fpgrpi systemd[2859]: Started GNOME Remote Desktop. abr 25 00:12:19 fpgrpi gnome-remote-desktop-daemon[23876]: Cannot load libcuda.so.1 abr 25 00:12:19 fpgrpi gnome-remote-desktop-daemon[23876]: Cannot load libnvidia-encode.so.1 abr 25 00:12:19 fpgrpi gnome-remote-de[23876]: RDP server started abr 25 00:12:19 fpgrpi gnome-remote-de[23876]: VNC server started To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-remote-desktop/+bug/1970139/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
