I just upgraded from 20.04 to 22.04 on a Lenovo IdeaPad 3 15ITL05. I wanted to use the new screen recorder, so I pressed PrtSc, which brought up the normal options. The screenshot function seems to be working fine, but when I choose to record, the symbol at the top of the screen pops up for a split second, then vanishes and nothing happens. Any ideas about how to fix this??
I have a few ideas. I used htop to view my running processes to figure out a little about the Screencast program.
Mine is here "usr/share/gnome-shell/org.gnome.Shell.Screencast" You can run the program and then check a few on your log files and look at the activity.
The -f option for tails lets you watch whats happening. Or just use tail -n 20 syslog and look at the last 20 lines in the log file.
other ideas...Using different file manager? limited user account? Screencast folder missing? not a Gnome desktop or installed different one?
tail -f syslog
And see if you find anything interesting. Also check auth.log, kern.log, Xorg.1.log, ....
Mine created a folder in /home/userMe/Videos/Screencasts and all my Screencast show up there in WebM format.
Let us know what you figure out
Update: Known issue for upgrades:
Seems that gstreamer-1.0 isn't upgrading correctly and the fix:
cd ~/.cache rm -rf gstreamer-1.0
or that might work
sudo apt reinstall gstreamer1.0-pipewire
