Hello, I am experiencing a slow boot speed on my laptop running Fedora. I have provided the specifications of my laptop, the version of Fedora, the boot time, and the running services at the time of boot.
Startup finished in 6.215s (firmware) + 7.096s (loader) + 1.532s (kernel) + 3.375s (initrd) + 1min 10.828s (userspace) = 1min 29.048s
graphical.target reached after 1min 10.809s in userspace.
On certain days, I experience a prolonged boot time. Usually, it takes 7 to 8 seconds, but it takes 1 minute and 30 seconds now. Why is that, and how can it be resolved?
