[Kernel-packages] [Bug 2044139] Re: Kernel image 6.5 (web-)midi problems
I also found this interesting page that discloses that Ubuntu kernel versions like 6.5.0 are not solely based on this version number mainline kernels but really contain much later versions https://people.canonical.com/~kernel/info/kernel-version-map.html but there is no version of this for current kernels. So I dont know if that is still the case for todays ubuntu kernels. (if so, this is extremly confusing to always set the minor version to 0 despite it's really anything later and such a map is needed to understand that) -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-signed-lowlatency in Ubuntu. https://bugs.launchpad.net/bugs/2044139 Title: Kernel image 6.5 (web-)midi problems Status in linux-signed-lowlatency package in Ubuntu: New Bug description: After the update to mantis, I have a problem with (at least - i have not yet researched further issues) Web-Midi applications running in the browser.

[Kernel-packages] [Bug 1973434] Re: massive performance issues since 22.04 upgrade
@uengberg: in my research for another bug/problem (https://bugs.launchpad.net/ubuntu/+source/power-profiles-daemon/+bug/1977660 - I did not yet document it there) i found out that power profile behaviour is strange and actually i realized that the settings available in gnome *do* have a short term effect on Kernel parameters, but keep jumping back to the other setting. Then I connected this finding mentally with the finding i made here, namely that performance is better in lxde then in gnome, and I tried to see whats happening if I completely remove the power-profile-daemon, because I though it is probably bad when a Kernel or the Thinkpad firmware cannot properly set power profiles and keepy jumping back and forth... Wile this is only how I imagine these things working with my less than incomplete knowledge, I can says than Video playback in gnome works quite nicely after having removed the dysfunctional power-profile-daemon package. You might try to see if that helps you too. BTW in my case video(and accompanying audio) is/was problematic in all browsers i tested - in firefox, chrome and chromium, as well as in Zoom App(which I guess is likely an electron app). I had no chance to test is zoom works now too. I still dont know if this all just is a symptomatic remedy or really the root cause, though. Just as much I dont know if this really is a Kernel, a thinkpad Firmware/ACPI, or another low level library problem. @mruffel: are there any cpu/performance tests suites we could run to make all this more measurable instead of having to say "oh run a bunch of Youtube videos and/or zoom calls and see if it starts stuttering after a while"? The thing not working properly could be video playback, but it could also just be some scheduling issue and a system that cant cope well with single processes creating short term CPU spikes, as gnome-shell does and as in Video Playback the RDD Process appears to cause. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1973434 Title: massive performance issues since 22.04 upgrade Status in linux package in Ubuntu: Confirmed Bug description: Hi, After upgrading to 22.04 i had to fight with massive performance issues.

I can browse the web, run multiple youtube vids at once, even in another browser, have thunderbird running, and a virtualbox machine open with another browser for some web app testing and everything runs fine and smooth, no lagging.

[Kernel-packages] [Bug 1973434] Re: massive performance issues since 22.04 upgrade
@mruffel: interesting, I am right now already at 5.15.0-37-generic from: APT-Sources: http://de.archive.ubuntu.com/ubuntu jammy-updates/main amd64 Packages I gave up with custom Kernels as it seemed they provide no clear improvement better then running the ubuntu package with iommu turned of as you recommended. The last I tried was 5.18.1, but that doesn't work with the virtualbox dkms stuff which I depend on for work. I assume this wont better with 5.19, but i can try later. I cannot say for sure if / how much of the problem existed in 21.10 because my usage scenario changed around the time when I updated - a new work project, more videocalls, and I am traveling and use the laptop more for media consumption as youtube and videos like this: https://www.zdf.de/gesellschaft/markus-lanz/markus-lanz-vom-7-juni-2022-100.html I had twice weekly videocalls with Teams in the browser which drove the CPU up and the fans on, but did not stutter to a point of being impossible. But now I (try to) use Zoom, every day, and it's basically not possible - I have to use my (twice as old and much weaker mobile CPU) windows tablet for this. I cannot "easily" start a full clean install as I need the machine for daily work, and setting everything up from scratch takes some while - but I will try to get a second disk to be able to do it but keep the exiting install to work as good as it is. I might be able to restore a pre-update state of my system into a free logical volume and run this. Will see how far i get! It might very well be that I have multiple problems at once and every one of them contributes a bit to the poor performance I see, also because multiple changes seem to lead to slightly better behaviour each: * turning iommu off makes things from extremely unsmooth to nearly acceptable * turning intel_boost off makes things a bit better and acceptable * moving from gnome to lxde gets me even pretty stutter free video(but not the UX I want...) It could be a combination of kernel / graphics library / gnome(-shell)... OR it could be *only* a kernel thing, but slightly suboptimal behaviour of graphics libaries and gnome. E.g. gnome-shell has a lot of short cpu load peaks on a single core, which should normally not block everything else but maybe can lead to video stuttering when process/IO management and scheduling are wrong in the first place... I'll keep testing and experimenting when I have spare time and report any findings here... -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1973434 Title: massive performance issues since 22.04 upgrade Status in linux package in Ubuntu: Confirmed Bug description: Hi, After upgrading to 22.04 i had to fight with massive performance issues.

I first suspected gnome-shell to be a culprit and had the impressions things where sligthly better when using LXDE as a desktop environment, but still I never got real good performance. it's a real hard to get a grip on problem, as I dont know how to instantly produce the problem and measure it as with normal bugs. The easiest thing I can do is open a web browser, got to youtube, and open a few videos in new tabs and try to play them, and skip back and forth to different points, and "pretty soon" I get a stuttering in the video, a mouse pointer not moving fluently, switching tabs taking multiple seconds that usually works in an instant, a browser process with multiple 100s of % of CPU and a RRD* process. these are things that work without a problem on a very old Lenovo x1 tablet with a mobile processor, and that i would expect to work equally easy on a pretty new X1 extreme with i9 processor and 32G Ram... I did some more testing ( I cannot call it real debugging as I dont know how to use proper tooling and stuff for these kind of analysis) and checked how other Distributions and other Ubuntu versions perform from USB Live systems and found that not only PopOS, but also Ubuntu 21.10, BUT to my surprise also 22.04 from USB Live system behave much better. So I thought i must have some setting wrong, but I didn't know which, until i tried to turn off Intel Boost because I remembered in Ubuntu Studio it is recommended to be turned off for good audio performance. This helps a lot! But, this is not what is different between 22.04 live - because there, Intel boost is ON and it still behaves good. I tried this with several browsers with always the same result, so it seems to be a generic graphics system/library, or kernel problem. It actually "feels" like some scheduling issue - which was the reason I tried the boost setting. I also tried with a new test user, to make sure it's not a userspace local setting, or any browser plugin. But the same problems with a new, "clean" user. The system I experience all this with has been installed first with 20.10, so it has multiple upgrades - it *could* be there is some other setting from previous software versions thats broken - but I have no idea what setting this could be and how I can search for it. It could also be some old version of some gnome, X11 ( I also tried Xorg as well as wayland, no noticeable difference) or graphics library, and the kernel package is the wrong place for this bug, but I dont know where to start with that then... -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1973434 Title: massive performance issues since 22.04 upgrade Status in linux package in Ubuntu: Confirmed Bug description: Hi, After upgrading to 22.04 i had to fight with massive performance issues.

Re: [Kernel-packages] [Bug 1973434] Re: massive performance issues since 22.04 upgrade
Hi Matthew, Yes, that looks very good! have to dig a bit deeper and do some more actual work, but at the first glance I can do the things that I described above where impossible! Thanks a lot! I tried to build 5.17.7 with the 22.04 config and make olddefconfig and then bindeb-pkg, but it took extremely much longer than with the 20.10 config, and after about 2 hours i saw it still hanging on dpkg-deb for the dbg package and even half an hour later not finish. I will try again tonite, probably doing a full "mrproper" before and letting it run over night to see if it really hangs or just takes extremely long. Actually I cant imagine why a dpkg-deb should hang, but I also saw now clues what it could be.

[Kernel-packages] [Bug 1713017] Re: Enable MIDI support
as far as I can see in the bluez package source, the midi option is enabled now, so it *could* be closed... But even though it's on, I dont get it working, so I cannot confirm for sure. Expectation is: when connecting to a device, I get an alsa sequencer client, but I dont see that happening. But also I am not sure if I use it correctly, as i see nearly no documentation about it, despite one place that said what I mentioned above in what I expect to happen. I dont even know for sure if this direction is supposed to be unidirectional or bi-directional. (e.g. if my laptop can be the midi host, device or both). I'll keep trying. If anyone has a pointer to docs how it is really supposed to work, so i can confirm, it would be helpful and this ticket could be closed. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to bluez in Ubuntu. https://bugs.launchpad.net/bugs/1713017 Title: Enable MIDI support Status in bluez package in Ubuntu: Triaged Bug description: Now that bluez has landed with 5.46-0ubuntu2, it would be nice to enable Bluetooth MIDI support.
