The machine is unusable when this occurs. Additionally, GIMP has begun crashing unpredictably. I have rebooted many times. I have changed the display drivers (currently using the X.org driver). None of this has affected the problem. I have searched online for possible fixes, and found nothing useful. HP's "support" is useless, since they only deal with Windows. StackExchange referred me to this site. I hope I have reported correctly. Thank you. --- ProblemType: Bug ApportVersion: 2.20.11-0ubuntu27.16 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: jiw2 5028 F.... pulseaudio /dev/snd/pcmC0D0p: jiw2 5028 F...m pulseaudio CasperMD5CheckResult: skip CurrentDesktop: ubuntu:GNOME DistroRelease: Ubuntu 20.04 InstallationDate: Installed on 2018-11-17 (830 days ago) InstallationMedia: Ubuntu 18.04.1 LTS "Bionic Beaver" - Release amd64 (20180725) Lsusb: Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 001 Device 003: ID 8087:0025 Intel Corp.
