If bluetooth is disabled in the BIOS, the bluetoothd process won't be running. bluetoothctl waits for that process to launch, which means it timeouts indefinitly, breaking suspend entirely. By checking if bluetoothd is running before calling bluetoothctl suspend works fine even if bluetooth is disabled in the BIOS. Signed-off-by: Dorian Stoll <dorian.stoll@tmsp.io>

# for an explanation/discussion. We do not unload/reload modules for now as
|
|
# the IPTS drivers should be able to resume/suspend without this. If you
|
|
# experience any issues on suspend/resume, please file an appropriate issue or
|
|
# join the discussion linked above so that we can fix it. As a temporary
|
|
# workaround, you may want to uncomment the IPTS-related lines above.
