Hey everyone!
I’m running Ubuntu on a ThinkPad X1 Carbon and recently noticed unusually slow boots.
After powering on, laptop shows the Lenovo and Ubuntu logos, then goes completely black and unresponsive for 5-10 minutes. If I click or press keys, it eventually wakes up to the login screen. Once logged in, everything works fine.
The weird part is that systemd-analyzereports reasonable startup times (~28s), but the actual experience feels much longer—as if something is delaying boot beyond what system logs show.
What I’ve Checked:
- Boot Analysis:
systemd-analyzeshows a ~28s startup, but actual experience is much longer. - Power Management:
cat /sys/power/stateshowsfreeze mem disk, but no hibernation logs (journalctl -b -g "hibernate\|suspend"). - SSD Health:
smartctlshows no errors or bad sectors. - Cisco VPN Logs: AnyConnect (
csc_vpnagent) repeatedly times out (SOCKETTRANSPORT_ERROR_CONNECT_TIMEOUT), possibly delaying boot.
Would appreciate any insights! 🚀
