What I tried
I tried removing/installing RoseGarden. I uninstalled and then tried 'apt-get --purge autoremove rosegarden' but it did not find anything after installing. I don't quite understand how a remove/install didn't change this setting back to its default -- since, in theory, it should have removed everything related to the app.
How I got here
I noticed the warning icon in the lower-right which (clicking upon) states "System timer resolution is too low". So, following some other info:
1. I installed the low-latency kernel (5.13.0-27)
2. Set CPU to "performance" for all four cores
Code: Select all
echo performance | tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor
The warning continued to display. So, going to the FAQ, I found the entry regarding this warning and changed the Sequencer timing source (https://www.rosegardenmusic.com/wiki/Fr ... o_low_mean) to 'HR Timer'. What appears to be happening is that it is grabbing the available cycles and not allowing the GUI to get any attention. So, if I could edit the setting (in some settings file or whatever) before running RoseGarden, maybe this could be resolved.
