Hey guys, another question from me

I'm really enjoying Bazzite for its working TDP settings, and nice scaling options, I think I can never go back to windows. Most of the time I'm using Moonlight to stream from my (wired) desktop (AMD 7800x3d + 4090) to my Legion Go, but I'm experiencing stuttering (and overlay info from moonlight detecting slow connection) roughly for 10 seconds every 5 minutes. Before and after the stuttering the stream is smooth. I tested HEVC/H.264 and bandwith options, tried several settings on the win11 host without any change in this behavior. I then installed Moonlight under Windows on the Legion Go, and the problem is not existent there. To further debug, I let a iPerf3 stream (with 10MBit/s, UDP) running in parallel to the moonlight stream in Bazzite, and when moonlight complains about bandwith, the network errors in iperf3 are peaking as well. Long story short: is the network driver that is used in Fedora/Bazzite the problem? Always thought, that Linux is especially bullet-proof when it comes to networking

Okay it’s now hardlocking in P3R loading screen

Kohega•2/28/24, 1:30 PM

will try to rollback or bootup a live usb

the only thing I did is update to pre-beta steam channel

could be a number of things, if you are suspecting its the linux driver, may look into dmesg output logs anything regarding the wireless driver. I'm not too familiar with the legion go, do you know what kind of wireless device its using?

I also wouldn't call it bullet proof, its about as bullet proof as any other piece of software, bugs come up, and sometimes gotta wait for kernel patches to fix them.

DevilFish303•2/28/24, 1:40 PM

my strategy for debugging any hardware issues is look for dmesg logs, and then google for lines i find in my dmesg logs, excluding any information that is unique to me (timestamps, hostname, etc.) and hit up all linux forums, arch forums are most useful since they tend to get hit by these kind of bugs first and they will link you to threads about ongoing bug investigations and PRs

DevilFish303•2/28/24, 1:42 PM

lastly, reason i asked if you know what kind of wireless device, is because idk if it will show up under

lspci

lspci

lsusb

lsusb

, try running both and see what comes up, sometimes knowing the vendor of the wireless device (and ideally model) helps in tracking down the state of support for it within linux kernel

XevveNOP•2/28/24, 1:44 PM

thx for responding @DevilFish303 , will dig deeper. Maybe someone has the feedback that he has the same experience with the Legion Go under Bazzite - or the opposite. lspci gives:
01:00.0 Network controller: MEDIATEK Corp. MT7922 802.11ax PCI Express Wireless Network Adapter

DevilFish303•2/28/24, 1:45 PM

ah that's it, try looking for anything relating to this in dmesg, see what is coming up

DevilFish303•2/28/24, 1:45 PM

also recommend in an ssh session run

sudo dmesg -w

sudo dmesg -w

and just leave it running while you stream, when you encounter the slowdown, see if there are any messages getting outputted as you're experiencing the issue

XevveNOP•2/28/24, 1:48 PM

good advice, will check that

XevveNOP•2/28/24, 1:56 PM

no messages in dmesg -w coming up during the moonlight stream and stuttering; is there a way to get more logging for the wlp1s0 device? I'm not very experienced with linux unfortunately.

DevilFish303•2/28/24, 1:57 PM

well on the brightside its not a driver issue

DevilFish303•2/28/24, 1:57 PM

actually i shouldn't say that, let me think of what else to check for

DevilFish303•2/28/24, 1:59 PM

so the next thing is monitor traffic with eBPF tool, i found a useful guide by redhat that can walk you through how to set this up: https://developers.redhat.com/articles/2023/07/19/how-retrieve-packet-drop-reasons-linux-kernel#using_tools_to_retrieve_drop_reasons though do note the warning at the bottom that not all reasons for dropped packets are covered

jw though, you mentioned you do not see these issues on windows at all, which makes me suspect if firewall is getting in the way, what's your network setup?

XevveNOP•2/28/24, 2:04 PM

firewall on Bazzite-side? My network setup is implemented with UniFi, I'm using 2 different APs in the house, the desktop is 1Gbps wired to a UniFi switch. There is no traffic shaping or internal network traffic filtering in place (which would affect windows then as well). I don't see roaming/hopping between the two different Access Points.

XevveNOP•2/28/24, 2:04 PM

Will now take a closer look to the eBPF tool

DevilFish303•2/28/24, 2:04 PM

not necessarily bazzite side, the default rules are pretty permissive out of the box, the ports required by moonlight are already open by default

XevveNOP•2/28/24, 2:05 PM

Whats weird is, that the problem occures to frequently, almost every 5-7min for only 5-10seconds. Is Bazzite doing something periodically in the background?

DevilFish303•2/28/24, 2:05 PM

this is what it looks like for me on the bazzite side

DevilFish303•2/28/24, 2:06 PM

but on the other hand, i also run a network wide firewall, so i can control how devices in my house can talk to each other

DevilFish303•2/28/24, 2:07 PM

make sure wlp1s0 is set to the same zone and the ports are open like this, i have absolutely no issues with these default rules

XevveNOP•2/28/24, 2:09 PM

Are you using Moonlight as well? What's your hardware?

DevilFish303•2/28/24, 2:09 PM

good question, maybe a bazzite dev can answer that better than me, I haven't taken the time to snoop around background processes, my understanding is bazzite devs just take fedora image as is, and just layer on gaming tools on top. It does use a custom scheduler from system76, among other gaming-centric optimizations, but if those things were issues im sure more people might've seen it

DevilFish303•2/28/24, 2:09 PM

yes! I stream from Bazzite desktop using sunlight (AMD CPU + AMD GPU) to living room HTPC running bazzite-deck also AMD CPU + AMD GPU

XevveNOP•2/28/24, 2:10 PM

you're right, can't be a generic issue

DevilFish303•2/28/24, 2:12 PM

ill try updating my stuff today and see if i can recreate the issue, i don't update my HTPC too often, maybe once a month, last time i streamed i had no issues, i can get back to you

DevilFish303•2/28/24, 2:12 PM

is your host windows?

TecN01R•2/28/24, 2:14 PM

What happens if I do a factory reset from the Game Mode system menu on Bazzite?

fiftydinar•2/28/24, 2:26 PM

You can maybe try to use different TCP congestion algorithm.
Bazzite uses bbr tcp by default, with fq packet scheduling.

Linux generally uses cubic tcp by default with fq_codel iirc

fiftydinar•2/28/24, 2:26 PM

that's if it's not the driver issue

Twin Nature•2/28/24, 2:27 PM

has anyone else had issues with bazzite crashing and forcing a reboot?

DDevilFish303 is your host windows?

XevveNOP•2/28/24, 2:31 PM

Yes, exactly. And Sunshine in 0.21.0.

DevilFish303•2/28/24, 2:33 PM

ah darn, so my setup won't be apples to apples with yours

DevilFish303•2/28/24, 2:35 PM

so im kinda worried if nvidia is doing something weird with encoding, i don't have a windows system or an nvidia card on hand i can play with to try it out, still ill give it a shot with my current setup

XevveNOP•2/28/24, 2:36 PM

Is Bazzite using the "NetworkManager"? (I'm on bazzite-deck-gnome)

XevveNOP•2/28/24, 2:37 PM

It periodically scans for wireless networks even if already connected... not every chipset is dealing with this cleanly, i'm trying to scan manually while in moonlight and check if I can trigger the lags this way

TTwin Nature has anyone else had issues with bazzite crashing and forcing a reboot?

DevilFish303•2/28/24, 2:37 PM

yes, but an update fixed it

DDevilFish303 yes, but an update fixed it

Twin Nature•2/28/24, 2:37 PM

huh okay, just the normal update through game mode or did you need to do anything via desktop mode?

DevilFish303•2/28/24, 2:37 PM

well actually in my case it wasn't bazzite itself crashing, but gamescope crashing

DevilFish303•2/28/24, 2:38 PM

do you reboot completely that you see BIOS logo flash up on the screen?

i hope its okay to link it, i got in trouble for cross posting last week... lol

Twin Nature•2/28/24, 2:39 PM

No, I think it's a game scope crash, but I just updated to latest via game mode tho

DevilFish303•2/28/24, 2:40 PM

yea in my case the issue just cleared itself up, it was annoying, i couldn't change hdmi inputs on my tv, that was enough to trigger the crash

Twin Nature•2/28/24, 2:40 PM

that musta been annoying

Twin Nature•2/28/24, 2:41 PM

rn mine is crashing when in game, not exactly sure why tbh

B0BB13H1LL•2/28/24, 2:57 PM

Will Bazzite upgrade to Plasma 6?
