Ah OK, that would explain it, thanks. > vesa.ko shouldn't be working with KMS.

Hmm, could this explain why vesa.ko can be loaded from loader.conf, but not via kldload(8)? OTOH, kldload'ing it later does not seem to work (ir)regardless of whether i915kms.ko is loaded or not... > I never have to hit the power button more than once to resume on a laptop > where resume works though. > > (True on my X220 and on a T440 both with Intel or Radeon graphics (all > using KMS). I'm about to try fresh -CURRENT on some HP AMD APU-based laptops, hence I'll ask: do aforementioned laptops suspend/resume without issues in X11 or on the naked console as well?

Well, technically, my laptop *does* resume with vt(4) + i915kms, just it takes a lot of power button hits and quite some time (up to several minutes), unless it dies somewhere during the process. I'll retest it against GENERIC and report in a separate email. On a related note, how does one configure sc(4) with old drm (vs. drm2) shall I need to try that? > FWIW, the HP netbook resumes fine with KMS as well for me.

Right. So far, I've been booting, kldloading i915kms.ko, zzz(8), resume. No X.Org was involved -- given how fragile suspend/resume is ATM, I'd like to iron out the issues with the pure console first. ./danfe _______________________________________________ email@example.com mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
