Can't suspend/sleep after upgrade to 23.10

[Jon Maddock]

After upgrading from 23.04 to 23.10, my laptop can't sleep: when trying to sleep, it immediately wakes up again. This occurs when no peripherals (Bluetooth anything, keyboard, monitor etc.) are connected too.

I have tried toggling "wakeup devices" in /proc/acpi/wakeup as in https://askubuntu.com/questions/598236/ubuntu-wakes-up-after-few-seconds-of-sleep, but disabling them all didn't prevent the computer waking up immediately.

Any help greatly appreciated!

Thanks,

Jon

I finally managed to fix this using the answer linked here: https://askubuntu.com/questions/1500474/cant-suspend-sleep-after-upgrade-to-23-10/1502550#1502550. It was due to some broken nvidia-related symlinks.
