I finally installed KX 14.04b this weekend. I've not got to use it much yet but I just wanted to give falkTX some initial feedback on its installation.

Despite having my laptop connected to the net via ethernet, I was unable to read the release notes during installation. Firefox opened but it said it couldn't connect to the release notes page.

A small problem that has been carried over from the 12.04 installer is that the text in the 'Edit partition' window is hard to read as its a dark grey font on a darker grey background.

The good news (for me at least) is that VAAPI hardware video decoding for Intel HD GPUs works fine under 14.04, which wasn't the case for 12.04. Playing a 1080p h264 video under VLC used about 37% of my CPU under 12.04 - this dropped to about 10% just by upgrading to 14.04 but after installing and enabling the VAAPI driver it fell to 1% CPU usage.

That's because I never wrote them.
There is a KX 14.04 ISO already, but it's not truly official.
I wanted to fix the Cadence auto-start issue and network password saving first, those 2 were showstoppers.
The 1st is fixed, the 2nd to be very soon.
Also now Ubuntu 14.04.1 has been released so things should be a bit more stable.

Shortly after carla2-beta2 I'll make kx-14.04.1 ISOs.

I keep forgetting about this one.
A screenshot of the issue is very welcome.

That explains that one then!

I forgot to mention the Cadence auto-start issue. Hopefully your fix will also cover the issue with the ALSA bridge that has emerged in 14.04 where both Stop and Start are often greyed out after starting JACK and you need to do a 'Force Restart' before you can enable the ALSA bridge. I never saw this happen under 12.04.

I have emailed the screenshot to you.

I'm sure I remember reading somewhere that 14.04 would auto-detect SSD drives and auto add discard to the fstab mount options. No such luck, which is a shame as Windows has done this (TRIM auto-enabled for SSDs) since Windows 7.

I need to clarify the ALSA bridge bug under the current Cadence package / 14.04.

JACK and the ALSA bridge both auto-start on boot successfully but if you stop JACK, both Start and Stop for the ALSA audio bridge get greyed out until you hit 'Force restart'.

the aloop bridge cannot be used when jack is not running, so of course it will be greyed out after jack is stopped.
when you start jack back again, the start button should become clickable thus give you the chance to start the bridge.

is this not how it is working for you?
(if not, try running cadence in a terminal, replicate the issue and see if it prints any suspicious messages)

The start and stop buttons for aloop become greyed out (when JACK is running - I know aloop depends on JACK being started) only when Cadence/JACK has been started automatically at boot, stopped and then started again. If I manually start Cadence via terminal or shortcut I don't see this bug.

Does not happen here (debian testing). not sure how I'll be able to test this...

If you can't spare 10GB or so for a 14.04 partition then you could install it under Virtualbox, qemu or whatever.

I have successfully shrunk Linux (and Windows/NTFS) partitions using gparted many times before without any issues.

Have you had chance to look at this yet Mr F? 14.04 being the new LTS and the base of the KX distro now, I'm sure you'll need a 14.04 install to debug something else like this before long!

Thank you for this manual. Helped me decide that I need to switch to 64-bit KXstudio.
Initially I downloaded the 32-bit version of KXstudio, as I thought that would improve compatibility.
But then I noticed that all ubuntu packages come with -i386 suffix, which supposedly means that they are poorly optimized for even as old a hardware as my 2007-made laptop with Core2Duo CPU.

I'd suggest this little bit of useful information appear in the "Downloads" section on the KXstudio site, somewhere around the .iso download links, so new users can make a better judgement than my initial one:
If your machine allows for it, the 64-bit version is recommended as it usually works faster. Note that you can still run 32-bit software under a 64-bit installation but not the other way around.

Now that 14.10 is out, its prob about time to update this manual.

The chapter that needs the largest overhaul is 'KXStudio and Free Software' as most of the non-free software has been removed from the KX ISO so much of it no longer applies, esp. the 'Specific KXStudio non-free software' section. This chapter was largely the work of Mr Wolf so I'm hoping for his input in updating it.

14.10 is out?
time files...

before anyone asks, the next KXStudio ISOs will still be based on 14.04.
I personally don't recommend anyone installing 14.10 unless strictly necessary. it's supported for a very short time by Canonical, meaning you'll have to reinstall something else just a few months afterwards.

Hi daeavelwyn

Thanks for that! I've updated the index page to include a link to the French translation

http://wiki.linuxaudio.org/wiki/kxstudio_manual

I apologise for not having updated the manual for the new release - I've not got round to installing it yet. I suspect (hope) its only the chapter on wineasio and reaper that needs updating so I hope to get that done shortly. Someone feel free to beat me to it! ;)

I still like KDE and buntu but I'm tending to use Cinnamon under Arch more at home these days.
