I wonder if there's a significant alternative to the current audio system in Ubuntu 20.04 -- PulseAudio+ALSA are awful? For a year now, I've suffered with the most frustrating breakdowns getting sound to pump out of the right interface without causing my machine to burn 200 watts to "compute" something. I love Linux, I love Ubuntu, I use it everywhere, but this little daily-frustration quietly drives me back to my in…

If you don't use bluetooth headsets you could use raw ALSA. Pipewire is the more mainstream (but new) alternative, as Pulseaudio replacement.

PipeWire looks like it's shaping up to be an excellent spiritual successor to (and unification of) both PulseAudio and JACK: https://pipewire.org/ https://wiki.archlinux.org/index.php/PipeWire

Is pipewire in Ubuntu 21.04? I think Fedora 34 has it.

It's interesting to see Wayland enabled by default. I'm curious to know what state Wayland is in nowadays, especially regarding how well it works with Nvidia cards. The last time I tried it out was around 2017ish when Fedora enabled it by default. It was 100% not ready then as it wouldn't even boot into the desktop with my nvidia card. Is it actually ready now? Does it work with nvidia cards? Does GPU acceleration wo…

From what I understand after briefly looking into this earlier this month the issue seems to be basically NVIDIA want to push their own buffer API (EGLStreams) rather than use the buffer API developers are actually using (GBM). If you use one of the "big" compositors like GNOME or KDE I believe they have sort of added EGLStreams support so you can use it on NVIDIA but it's not perfect. If you use a more niche one, e.…

There's also the External memory extensions for Vulkan and OpenGL. All the vendors support the Vulkan api. https://vulkan.gpuinfo.org/listdevicescoverage.php?extension...

But not sure about the OpenGL (I think Nvidia do).

These apis let you export a FD for sharing. Pretty sure you can import (scanout compatible) objects into DRI/DRM/KMS. Which is what libgbm does for Mesa drivers.

Although most compositors (including wl_roots based ones) still use libgbm as they might also need to support embedded hardware. (eg: Tizen).

(In the original release of Vulkan intel has a weird "unofficial" extension that let you export a FD. and khr had a VK_cube demo that could directly use KMS with Vulkan using this "extension". This was removed as it was only there to test Vulkan before any window manager integration was implemented)

I put the beta on an AMD Lenovo Yoga Slim 7 yesterday. The thing's slick as hell. As far as I can tell so far, everything just works.

Apropos of which, does anyone know why trackpad interfaces are an area of active change? It really surprised me when the trackpad got disabled by closing and opening the lid on 20.10. I naively think of trackpad hardware as mostly a solved problem.

Thank you to Canonical for keeping Ubuntu a free and open source operating system with long term support! With the death of CentOS (replaced by an unstable upstream of RHEL) it means a lot to the Linux community.

I fail to see how moving to a rolling release strategy results in any kind of "death", seems like FUD to me. Rolling release, trying to stick to upstream releases as closely as possible, works well with Arch Linux, I'm glad CentOS learned from Arch Linux success. DISCLAMER: I'm not even a CentOS user, but I just like what RH does and has done for "the Linux community" as you call it (I would just call it "society" but whatever).

This got me reading. I didn't realize how quickly this change to PulseAudio might be. It looks like Fedora 34 is actively moving to PipeWire as it's new default. I wonder what's preventing Ubuntu from making a bigger change. More downstream dependencies? https://wiki.debian.org/PipeWire

I tried Wayland on 20.10 a few month ago and concluded it wasn't ready for daily use. The worst thing is that it would RANDOMLY cause Gnome to restart while closing all my applications. Also the cursor was jumpy and laggy sometimes (especially when opening context menus). Is anyone aware if these issues still happen?

>The worst thing is that it would RANDOMLY cause Gnome to restart while closing all my applications. Question: Is this a GNOME architecture issue? I hope KDE could avoid this issues, atm on Xorg I can restart the window manager and the desktop shell without losing any data.

I don't have a firm answer, but considering how much Wayland pushes off on the compositor (seemingly everything, nothing is ever Wayland's fault or responsibility) I'd expect that the compositor (every desktop environment or WM also needs to be a compositor, now) crashing is identical to all of Xorg crashing, not just the DE or WM under Xorg crashing.

Earlier quoted context omitted.

You can find 21.04 here: https://www-ftp.lip6.fr/pub/linux/distributions/Ubuntu/relea...

These are all beta images.

If you install the beta from a week or two ago and then do a 'apt update' followed by 'apt dist-upgrade', it'll download maybe a few hundred MB of stuff, need to reboot once, and will be the same as the release.

Yes. And always has been since like forever ago. I'm all for choice and diversity, but I've personally never understood all the love and excitement and attention that GNOME has gotten ever since Canonical got behind it and dropped Unity.

I'm certainly not it's target audience - running XFCE, LXDE/LXQT, and i3/Sway over the years - but it really gobsmacks me to hear the cheerleading over what seem like really basic fixes, like "now the single-threaded shell crashes to login less often! Horray!"
