02:29 <leezu> It seems there is a regression on 6.0 with lazor? I'm seeing the following error when booting up with external screen + usb hub connected over usb-c. External keyboard didn't work at first until I replugged the usb-c connector, at which point the error was printed a second time. "rcu: INFO: rcu_preempt detected expedited stalls on CPUs/tasks: { P2483 } 21 jiffies s: 389 root:

02:29 <leezu> 0x0/T"

02:48 <steev> i see those on the c630 too, have for a while

02:48 <steev> never could figure out what it is

06:25 <ardb> so external display works now on c630? anything in particular i need to enable in my kernel config?

14:59 <steev> the patches aren't in the kernel yet, it needs bamse's patches for the EC, and if it throws an error, you need to flip the usb-c connector and plug it back in

15:03 <ardb> got a link to those patches?

15:04 <ardb> and it's only the port on the right, right?

15:05 <steev> https://lore.kernel.org/all/20220916200028.25009-2-quic_bjorande@quicinc.com/

15:05 <steev> si

15:06 <steev> only the right port (not sure if that's a limitation of the patches or if it's the limitation of the ec )

15:06 <steev> gotta find his older stuff

15:06 <ardb> same on windows

15:07 <steev> ah, didn't know that

15:09 <steev> https://lore.kernel.org/all/20220810035424.2796777-2-bjorn.andersson@linaro.org/ this

15:11 <steev> i believe both of those are required for it to work, and if you use gnome, you should run it on xorg not wayland

15:11 <steev> mutter has issues

15:11 <ardb> does that replace the some-battery stuff?

15:12 <steev> yes

15:13 <steev> oh wait

15:13 <steev> https://lore.kernel.org/all/20220810030500.2793882-2-bjorn.andersson@linaro.org/

15:13 <steev> that too

15:13 <ardb> and the drivers for that?

15:13 <steev> ^

15:13 <steev> they are still WIP, and changes have been requested, but for the most part, it works

15:15 <ardb> good stuff - i'll have a go with those tomorrow

15:51 <gwolf> steev: FWIW, I never tried too much, but for the C630 I have very good performance under Wayland, while it was close to unusable under Xorg

15:51 <gwolf> Maybe I didn't load the right modules for the GPU... But anyway -- I don't run Gnome, but I'd prefer Gnome on Wayland

15:52 <gwolf> (unless there's something very severe I missed)

15:58 <steev> gwolf: there's an open issue about mutter >=42 crashing with wayland - https://gitlab.gnome.org/GNOME/mutter/-/issues/2398 - that's the main reason

15:59 <steev> i also prefer wayland :) and the issue doesn't show up at all on 3.38 (but they added atomic stuff in 40+ (not sure when exactly)) so debian stable is fine

16:00 <gwolf> oh, bummer :-\

16:00 <gwolf> I guess the crash is only on Adreno or ARM or something like that...?

16:00 <gwolf> As it sounds like _way_ of a release blocker otherwise

16:02 <steev> i unfortunately don't run gnome on any systems but adreno, and i know it happens there

16:02 <steev> i do believe it's specific to adreno, i just don't know enough to fix it

16:03 <gwolf> right, and it's not popular enough I guess

16:03 <gwolf> unless you count Gnome for Tablets

16:03 <travmurav[m]> isn't this that issue that is only hit with the external display?

16:05 <travmurav[m]> yeah, seems to be

16:13 <ardb> does it only happen when using both displays at the same time?

16:13 <gwolf> Say, re:external displays...

16:14 <gwolf> ...Do you know if Anderson's kernel patches for having the C630 recognize the HDMI output have been sent or accepted upstream?

16:14 <gwolf> (read: Should I attempt to use 6.0?)

17:35 <steev> they aren't yet

17:35 <steev> iirc, they kinda want him to do it as mfd driver, but, i haven't kept up

17:49 <steev> sorry - sent yes, accepted, no

17:49 <steev> at least, not all of them

18:01 <gwolf> OK. Well, that's the right path at least :-)

18:01 <gwolf> I can at least stay with 5.19 and be happy

18:01 <gwolf> the only pain point I've had (but it's so minor I have learnt not to even care is that... audio really still sucks :-(

18:02 <gwolf> And I have *two* external USB audio controllers -- but this 5.19 errors when trying to use any of them

21:49 <NomadNaomie[m]> will 6.0 fix the X13S' Audio and BT?

22:15 <mani_s> NomadNaomie[m], unfortunately, no

22:17 <clover[m]> Nomad Naomie: I use a usb BT adapter for now, it works well as a workaround!

22:17 <NomadNaomie[m]> Yeah I have one too but I was hoping to use it for audio :

22:17 <NomadNaomie[m]> s/:/:|/

22:20 <clover[m]> X13s support seems to have slowed down :(

22:21 <HdkR> It's a shame, I just had three X13s laptops land on my door this morning

22:24 <NomadNaomie[m]> I might have to dig deeper into getting recovery media for W11 then and dual boot

22:26 <mani_s> BT and audio are still wip for x13s

22:42 <clover[m]> X13s shout-out https://www.omgubuntu.co.uk/2022/10/linux-kernel-6-released-new-features

22:42 <clover[m]> >The (expensive) Lenovo ThinkPad X13s laptop, which runs on the Qualcomm Snapdragon 8cx Gen3, starts to pick up support. The ThinkPad X13s is pre-loaded with Windows 11 for ARM but, with Linux support now in the formative stages, this could be a great reference device for Linux ARM enthusiasts.
