Here's what has made my resumes work every time (so far dozens of resumes since last failed one, including some really adventurous, like suspending in a middle of a 3D program running and resuming just fine): *Kernel 3.2.0-33 lowlatency (I don't think lowlatency is necessary but I use this computer for audio work so it is a must for me); *Ubuntu 12.04; *fglrx 12.11 beta11 driver (released on Dec. 3rd, 2012, which fixed all sporadic "ASIC hang happened" kernel panics for me, no patching was necessary to build a working dkms), and *Boot kernel flags: quiet splash threadirqs acpi_sleep=s3_bios,s3_mode,old_ordering,nonvs,sci_force_enable pci=nocrs hpet=disable I don't think I need all the flags in acpi_sleep, so one would need to weed out ones that don't matter, but out of desperation I added them all just to see. I know that s3_bios flag alone made things a bit better but not 100% (using that alone I had approx. 1 in 10 resumes freeze). But the latest flags pci and hpet have made it perfect (at least so far) on HP dm1z with AMD APU (HD6310). If this holds up then my notebook has everything working (finally!), like it should :-) P.S. Things I also tried, so others don't bother with, are: *changing sleep scripts by adding 2 second delays and/or disabling them altogether; *switching to virtual console 1 and back (via script by calling chvt 1 and chvt 7 respectively) during suspend (both going back and forth during single action and going to 1 right before suspending and back to 7 when resuming) *using custom script and variations thereof that is currently floating online (20_custom_ehci-hcd) and moving things around in there *trying to switch to metacity before suspending (via script) and then reverting to compiz -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1082851 Title: Screen stays black after suspend with AMD Fusion APUs and fglrx driver To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1082851/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
