resolved the issue where the laptop **immediately woke from suspend** by disabling specific ACPI wakeup devices.
#### 🛠️ Fix (temporary): ```bash echo XHCI > /proc/acpi/wakeup echo RP05 > /proc/acpi/wakeup ``` This made suspend/resume work correctly. #### 🔄 Automation (persistent across reboots): Created `/etc/rc.local`: ```bash #!/bin/bash echo XHCI > /proc/acpi/wakeup echo RP05 > /proc/acpi/wakeup exit 0 ``` Created and enabled a `systemd` unit at `/etc/systemd/system/rc- local.service` to run it at boot: ```ini [Unit] Description=/etc/rc.local compatibility ConditionPathExists=/etc/rc.local [Service] Type=forking ExecStart=/etc/rc.local start TimeoutSec=0 StandardOutput=tty RemainAfterExit=yes SysVStartPriority=99 [Install] WantedBy=multi-user.target ``` Enabled with: ```bash sudo systemctl enable rc-local ``` #### ✅ Result: Suspend/resume now works reliably across reboots. `XHCI` and `RP05` stay disabled as wakeup sources. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1981141 Title: Acer Swift SF114-34 standby/suspend/resume issue To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1981141/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
