On 8 (.1 and .2) I only had to leave uhci, ohci and ehci (not usb) out of kernel and load / unload those around suspend/resume, but that's no longer needed on 9 here. > Does suspend/resume work for anyone? Likely not very exciting news for most, but my '02 Thinkpad T23 reliably suspends and resumes since 9.1-R with zero configuration. Haven't tried it yet with X, might need hw.syscons.sc_no_suspend_vtswitch=1 for that as 6.x, 7.x and 8.x always required, but that's an old S3 Savage video, with working IBM-written ACPI/BIOS. More modern video chips and drivers seem to be far more problematic, not to mention slightly dodgy ACPI code .. cheers, Ian > Matt > > On 06/28/13 15:19, Stefan Horomnea wrote: > > Yes, I did try, didn't help. > > > > > > On Mon, Jun 24, 2013 at 4:30 AM, matt > > wrote: > > > >> > >>> which I think are after I manually power-off and power-on the > >>> laptop.
