Well, for me, .36 did not help, and current natty just doesn't suspend at all (2.6.37-5-generic). > So if we find a set of quirks which improves matters on these models, > I'm happy to put them into pm-utils in a maverick update.

I experimented with making sure that '--quirk-no-chvt' was not added in my pm-suspend, although I did so via hackery (ie, commenting out QUIRK_NO_CHVT="true" in /usr/lib/pm-utils/sleep.d/99video). > Thus I doubt that this is a sufficient workaround, and the > comments above seem to indicate that it doesn't actually fix the > problem.

My guess as to why my suggested hack worked where the quirks did not was timing, my hack runs further away from the actual suspend than the pm-quirks does. I agree, its not sufficient for a -updates. If the quirks could be set for this model, then that might be sufficient. -- lenovo/thinkpad T400[s]/T500/W500/X60 suspend fails https://bugs.launchpad.net/bugs/625364 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
