Upgrade Ubuntu 21.04 to 21.10 20211021 Utilised command line do-release-upgrade to Impish Indri. Ubuntu (Wayland) would not start so reverted to Ubuntu on Xorg. Everything else seems fine after updating some GNOME shell extensions (dash-to-panel, frippery move clock, open weather, panel date format). The workrave panel extension is not working though. An update resolved that. Wayland works after removing some very old (1990’s) DISPLAY environment variable manipulation in .bashrc. However, screen capture software (SimpleScreenRecorder and OBS) don’t work with Wayland.
