@alexhammy Now to be fair, the version of Ubuntu which is satisfied for this thinkpad is 20.04, and I am running 24.04. Naughty me
(If I were running 20.04 I *would not* be seeing the problem with sleep/wake; it is specific to newer Linux kernels, so it impacts 23.10 and 24.04 but not 22.04 or older)
@mcc same except it's 22.04 that I'm using which is strictly speaking qualified for my laptop model but only with a different dGPU
