Suspend and Resume with ACPI

Filed under
Linux

"It took me quite a while to realize the real root cause of the VAIO - and probably many other machines - suspend/resume regressions, which were unearthed by the dyntick / clockevents patches," Thomas Gleixner explained regarding two patches for fixing suspend issues that Andrew Morton experienced with his VAIO laptop.

He continued, "we disable a lot of ACPI/BIOS functionality during suspend, but we keep the lower idle C-states functionality active across suspend/resume. It seems that this causes trouble with certain BIOSes, but I assume that the problem is more wide spread and just not surfacing due to the various scenarios in which a machine goes into suspend/resume." Thomas concluded, "I really hope that this two patches finally set an end to the 'jinxed VAIO heisenbug series', which started when we removed the periodic tick with the clockevents/dyntick patches."

Linus Torvalds expressed some concerns.

Leftovers: KDE

  • KDE's Project Neon Begins Publishing Daily Wayland Images
    KDE -- KDE's Project Neon has begun publishing daily images of the latest KDE Plasma stack powered atop Wayland rather than the X.Org Server. Jonathan Riddell passed along word that daily ISOs are now being spun of the freshest KDE development code with KWin acting as a Wayland compositor. The OS base is still Ubuntu 16.04 LTS.

Open source near ubiquitous in IoT, report finds

Open source is increasingly standard operating procedure in software, but nowhere is this more true than Internet of Things development. According to a new VisionMobile survey of 3,700 IoT developers, 91% of respondents use open source software in at least one area of their software stack. This is good news for IoT because only open source promises to reduce or eliminate the potential for lock-in imposed by proprietary “standards.” What’s perhaps most interesting in this affection for open source, however, is that even as enterprise developers have eschewed the politics of open source licensing, IoT developers seem to favor open source because “it’s free as in freedom.” Read more

Ubuntu 16.04 – My Experience so Far and Customization

While I earnestly anticipated the release of Unity 8 with Xenial Xerus (after watching a couple of videos that showcased its function), I was utterly disappointed that Canonical was going to further push its release — even though it was originally meant to debut with Ubuntu 14.04. Back to the point at hand, I immediately went ahead and installed Unity Tweak Tool, moved my dash to the bottom (very important) and then proceeded to replace Nautilus with the extensive Nemo file manager which is native to Linux Mint and by far superior to the former (my opinion).
