I have a new Ubuntu install (22.04.2) on a Lenovo ThinkPad T460. It's actually set up as dual-boot with Windows 10. I'm using the XFCE desktop with lightdm as the display manager.
When it boots, I get a small dialog box that says "System Program Problem Detected". If I click on "Report problem", nothing seems to happen. If I click on either button the system seems to run normally.
/var/crash is empty
If I choose System -> Logs from the XFCE menus, the only "Important" log that I see is:
Other Error opening PCM device front:0: No such file or directory
A check in syslog shows this message as being generated by pulseaudio at startup. I sort of assumed that the PCM device was a sound problem, but system sounds play normally. (and I still don't know if that's what's causing the dialog :-). The only place the "front:0" string ever shows up is in the output of pactl:
pactl list | egrep "^Source|^Sink|device.string"
Sink #0
device.string = "front:0"
Source #0
device.string = "0"
Source #1
device.string = "front:0"
device.string = "0"
Where can I look for more detail on this? Any other way to find the cause of the "System Program ..." dialog?
Thanks!
