KXStudio 18.04 Testing

Postby falkTX » Sat May 19, 2018 11:40 pm

Hello everyone, it is finally time!

Preparations for a 18.04 KXStudio ISO release have been happening for some time.
KXStudio 18.04 will use Ubuntu with Neon repositories as base system.
It is still quite incomplete! Not even Neon is fully ready for 18.04 yet, so the image is using the dev/testing version of its repos, with some old 16.04 packages that have not been ported over yet.
(In case it was not obvious, this means it uses KDE5 Plasma as desktop environment)

So an alpha ISO file for KXStudio 18.04 is now ready. But before downloading, please note!!
1. It is not meant to be installed!
It contains development testing repositories, which can break anytime you try to update it
It is also unfinished, the image is meant for early testing purposes only.
2. installation fails! so dont try to install it
3. boot splash does not show logo, something regarding plymouth is not setup correctly at the moment
4. boot option "Check disk for defects" does nothing
5. Kubuntu text displayed a couple of times, needs to be replaced with KXStudio
6. several tweaks to KDE still TODO, including:
- initial wallpaper
- hide pulseaudio-only mixer from systray (kmix is there and starts automatically)
- porting over the extra dolphin actions we had in KDE4
- initial start menu items

That said, here's the precious link: http://download.linuxaudio.org/kxstudio ... 8.04a2.iso (Intel/AMD 64bit systems only)
sha256sum is 09f3ed39641abfa126e561c0f9e64879f7e46d6b3b0410e1ed2f9703c784c11d

Oh, and before you ask, updating from 16.04 to 18.04 is for sure not a good idea, don't do it.
Specially with Neon, as 18.04 is not officially supported yet.

To use the image, you can just "dd" it to a USB stick, like so:

Code: Select all

sudo dd if=./KXStudio_18.04a2.iso of=/dev/sdX bs=512K

Use

Code: Select all

sudo blkid
to get list of devices. Use with caution, one mistype and you can delete your main partition!

You can always go the old way, and burn it into a DVD for booting.

Regarding testing, any kind of input is useful at this point really. Like..
Does it boot?
Does JACK start by default?
Is there graphical issues, corruption, slowdown?
Does anything look out of place?
Any apps crashing?

I will try to test this later.

Meanwhile, what does kmix offer that the standard applet doesn't? I just installed it and it gives sliders for the same things but has less functionality.

kmix does pretty much the same thing, as it can integrate with pulseaudio streams too.
kmix systray does not integrate with plasma applets, it acts as a regular non-kde systray.

the plasma applet only works with pulse, and that is the issue.

But that's what I am confused about, if I have jack running then kmix offers no difference at all:

What else is kmix supposed to work with?

Is that on the ISO?
In order to make kmix usable, you need to set an environment variable.

On my system I have this:

Code: Select all

$ cat .bash_aliases | grep KMIX
export KMIX_PULSEAUDIO_DISABLE=1

No, this was inside my installation of neon.

Interesting, that does change it considerably and I can see why it would be useful if you run jack all the time.

I haven't had time to check the iso yet but will hopefully in the next day or two.

Just gave it a quick try. It booted fine, jack was started and I didn't encounter any graphics corruption. Opened up a few programs and didn't get any crashes, although I didn't try to do much when they were open. Basically, nothing seemed unusual except the plymouth issue.

The network didn't start. I am using dhcp connection, but not only the network manager didn't autoconnect as expected, but i didn't managed to start it throughout the whole session.
#systemctl start NetrorkManager and #systemctl start dhcpcd, didn't do anything.

I am not sure that the system makes sure that your soundcard is your main audio device on boot, instead of alsa-loop or for example the camera or the midi keyboard. Here is more on the topic:
https://wiki.archlinux.org/index.php/Advanced_Linux_Sound_Architecture#Set_the_default_sound_card

Also the cpu governor is set on powersave by default, while performance is recommended for a realtime audio computing.

Jack seems to work fine. Unfortunately the problem with pulseaudio bridge defaulting on maximum outputs instead of 2-Stereo is still persistent. The solution is to limit the jack outputs to 2, while a scenario with pulseaudio outputting 2 or manually defined channels is entirely possible.
I couldn't manage to test some vulnerable apps like the web browser because the lack of internet connectivity.

In conclusion. This system in this form is not ready. There are places for improvement. Things that are an integral part of the out-of-the-box linux audio experience.

Keep up the good work falkTX,
cheers,

HI, Thanks for the great work.

My setup:

Fujitsu Esprimo Silent PC
Core 2 Quad Q8400
84GB RAM
M-Audio Fastrack pro 2x4

Testing:

No issues on boot
Cadence used to configure Jack 44.1k 256 Sam 2 Buffers, Asla and Pulsaudio -> all working

Guitarix
Hydorgen
Carla w Calf plugins and gx plugins all worked

Had problem with my new Wifi adapter (but I know I need to integrate it into the kernel later)
Used my old Wifi adapter (Realtek Semiconductor Corp. RTL8187 Wireless Adapter
) and it works.

Had to setup DNS by editing /etc/resolv.conf

Just added

nameserver 8.8.4.4


to the file. Network worked after that.

Will continue testing.

Cheers and thanks again.

I tested the ISO and I loved it! It's very stable and everything seems to work just fine. Congratulations for this awesome work! Can't wait for the actual release ;).

Cheers,

Rodney

I'm testing it on two machines at the moment, an Imac27 and an Acer desktop.
On the imac, which as usual I have to start with nomodeset, I can't connect to the internet. The network connects ok but Firefox fails to find the address.
I tried adding DNS info but to no avail, and I wonder if it is due to the Mac address randomisation that has been a problem. I shall try and find out more later.
The other problem that I had with the Mac was that after successfully connecting to my usb soundcard with cadence, I then tried to connect to the digital onboard Mac, out of curiosity and jack could not start. I checked the logs and then cadence crashed when I selected configure.
The error was a dbus.proxies.introspect.error did not receive a reply - tryCloseJackDBus() failed.
The iMac is connected to the router via WiFi, but the Acer is connected via cable and there is no interface showing at all in Network manager and there is no ifconfig tool available so I can't say much more.
Apart from that it looks fine and seems to work well. It's nice to see it coming together.
Ubuntu studio have just announced that they will drop support for 32 bit and will use plasma for their next release, and fedora jam are already using plasma, so there is some homogeneity I guess. Have you considered supporting one of the other distros like Ubuntu studio instead of maintaining a separate distro? Just out of interest, it seems like a lot of work plus the repos and software that I think is an invaluable addition to Linux audio.

For anyone who has had problems connecting to the internet via wifi using the livecd, the file /etc/resolv.conf is a dead link.

The best thing to do is to make a new link to point at /run/NetworkManager/resolv.conf

So, the following commands :
sudo rm /etc/resolv.conf
sudo ln -s /run/NetworkManager/resolv.conf /etc/resolv.conf
sudo systemctl restart networking
sudo systemctl restart NetworkManager

That should fix it, I think. It works for me.

Hi FalkTx,

I have been using the live kxstudio today and there are few, if any problems, once I've run an update, which installs mostly ok. It seems that a lot of neon issues have been sorted out.

If I try and install it, are there likely to be any boot issues or other problems that I might run into?
I'm reasonably competent with Linux, having used it for over ten years at a reasonably technical level.

Cheers
