[13:10] <BluesKaj> Hi all
[21:24] <mmikowski> RikMills[m] Eickmeyer: FYI, night color + intel + steam == flicker fest
[21:25] <mmikowski> I've explicitly disabled it by default in next setting update; also document on site.
[21:26] <mmikowski> This on 5.19 kernel. I believe it is the same on oem kernel, but since I can't uncook that egg ... :P
[21:26] <mmikowski> 5.19 hwe vs. 5.17 oem.
[21:28] <arraybolt3> mmikowski: I mean, is there anything keeping you from installing the 5.17 OEM kernel stack and then uninstalling the 5.19 HWE stack on an installed system?
[21:28] <arraybolt3> I've documented how to switch kernel stacks before.
[21:28] <arraybolt3> https://discourse.lubuntu.me/t/lubuntu-22-04-2-lts-upgrades-still-using-the-5-15-ga-kernel/4042/8?u=arraybolt3 This is for switching from HWE to GA on Lubuntu, but with some tweaks it could likely work for witching from HWE to OEM 5.17.
[21:37] <mmikowski> Aye, sorry Aaron! I should have put you into the cc list.
[21:37] <mmikowski> Well, no.
[21:37] <mmikowski> But I don't think 5.17 fixes it.
[21:38] <mmikowski> The flicker was there before. I can look a little deeper, but it appears almost all the fixes that matter to us have moved forward to 5.19 HWE.
[21:38] <mmikowski> It is the interaction between Intel GPU and night vision. 
[21:39] <mmikowski> We already found and fixed a number of i915 flicker related settings (mostly modules), but I think what made this come up again is for some reason night color was getting set during burn-in.
[21:39] <mmikowski> So the Steam tests got all flickery.
[21:39] <mmikowski> Turn off the night color, and it's fixed.
[21:40] <mmikowski> Of course, absolutely no issue with NV graphics.
[21:40] <mmikowski> Haven't search the bug db for this yet; it's definite on X11. Haven't checked wayland yet.
[21:40] <mmikowski> just wanted to give you a heads up.
[21:41] <mmikowski> For RikMills[m] and Eickmeyer, I think it's very important for a default settings consideration.
[21:41] <mmikowski> Also for documentations. +cc ahoneybun[m]
[21:42] <Eickmeyer> mmikowski: #ubuntu-kernel
[21:42] <mmikowski> Since Kubuntu ships with 5.19 HWE IIRC, and its probably better to start with something that doesn't have night color but works on demanding gfx out of the box.
[21:42] <mmikowski> Hi Eickmeyer!
[21:42] <Eickmeyer> Hi!
[21:43] <mmikowski> Ok, I'll add that to my lurk list.
[21:43] <Eickmeyer> Basically, if it's a kernel issue (and not hardware-specific), that's a place to talk to.
[21:44] <Eickmeyer> I, personally, have seen no issues on any of my hardware with i915. Tells me it's specific to whatever hardware you are testing on.
[21:44] <mmikowski> Thanks. It may be limited access.
[21:44] <Eickmeyer> But, you haven't mentioned the hardware you're testing on.
[21:44] <mmikowski> That's the nxg2 and xeg2
[21:44] <mmikowski> 1260p
[21:44] <mmikowski> i7-1260p
[21:45] <Eickmeyer> Ok, might be limited to that hardware then.
[21:45] <mmikowski> It might
[21:45] <Eickmeyer> Remember how intel gets very specific in their own MB manufacturing?
[21:45] <Eickmeyer> Not generic at all as you'd hope.
[21:45] <mmikowski> Just thought I'd let you know. It is definitely confirmed on there, and those are very popular CPUs.
[21:45] <mmikowski> Oh yeah.
[21:45] <Eickmeyer> CPUs, yes, but not MBs.
[21:45] <mmikowski> right
[21:47] <mmikowski> Like I said, just an fyi.  We'll look at earlier revisions and see if it replicates.
[21:50] <mmikowski> IIRC, xeg2 also had that issue.  But we'll see.
