ship HWE Linux builds
Closed, ResolvedPublic

Description

Canonical/Ubuntu are finalising plans for HWE Linux builds. We've suggested in the past we'll use this (and on desktop the non-HWE build isn't supported as I understand it) so we should probably switch. Do we switch to -edge or the boring one?

I've running it and it works fine except Virtualbox doesn't load because the module doesn't exist

the boring one

It is my understanding that we don't need to do anything though. To finalize this Canonical would have to change the platform seed of xenial at which point we'd be automatically picking this up as well.

We may want to wait a bit after Ubuntu pushes 4.8 out.

  • I am seeing peculiar line artifacts upon typing in konsole with zsh on my xps13 with intel graphics (a couple pixel line below the current text line is translucent and showing the desktop wallpaper. Which my have to do with the intel modesetting driver
  • broadcom driver dkms is broken according to allee on IRC (proposed pocket has a fix but that apparently just makes the module build and subsequently crash and be useless)
  • people suggested that amd drivers may not build with 4.8, although I find that a bit weird and haven't checked up any further

I currently do not have a slimbook, but if the konsole artifacts are in fact a general problem with the driver it stands to reason that the slimbook would have the problem too and we shouldn't roll out 4.8 adoption until a fix is devised.

As it stands right now I am somewhat content in ignoring broadcom-sta as broadcom is always a clusterfuck anyway and there is a fix on the table, just needs carrying into SRU.

At any rate my POV is this: Assuming the user gets working eth and working video of some sort they can install and then switch the 4.4 kernel if that happens to work better for their hardware or the binary blobs they use. As I had no reports of eth or video failing or the kernel as a whole being panicware, the only thing that sets a bar beyond booting+eth+video is the Slimbook.

go for it, we can always fall back on the defense of "we just ship what ubuntu ships"

what about existing installs?

they'll stay on 4.4 I'd say. otherwise we for example break people's shitty broadcom wifi

hum, that's not what Ubuntu does surely?

That's exactly what ubuntu does. Existing install stay on 4.4, new installs get 4.8 and subsequently roll to future HWE stacks.

That being said we can also open a task to reevaluate the situation in a month. If the broadcom issue is solved by then we can force existing systems to 4.8 for all I care. That being said, how would we force upgrades anyway? We can't really make the desktop depend on 4.8 as that means people couldn't downgrade to 4.4 as grub will default to the latest all the time and when upgrading to mainline they'll always have 4.8 around with no way of removing it without also removing desktop.

oh well if that is what ubuntu does then fair enough

New User Edition image installs and runs fine complete with hwe packages

big up on social media and close
