Two problems after a distribution upgrade to Buster
1. At login window after boot up the desktop selection is locked a
Gnome. That is, if the symbol to change the desktop selection is
selected a list of available desktops is displayed with a dot indicating
Gnome is the current selections. There is no way to move this dot to
another selection. The mouse is frozen and I have tried every key on the
key board.
2. There is no sound. The alsamixer and the Gnome sound tool show only
an HDMI option but my monitor has no speakers. If I reboot to Stretch
there is a line out option and there is sound from my external speakers.
So rebooting to Stretch solves the sound problem but not the desktop
selection problem.
Kernel problem? Gnome problem? Pulseaudio problem?
