I have not used the chromebook since a long time (Pianoteq was v5.1.4 the last time), it is just my “backup-pianosystem”. But yesterday I wanted to start PTQ and it failed with “No Chromium OS X server is available” :-/
Searching the web shows, that Google replaced the GUI subsystem X11 in one of the hidden updates with something own called “Freon”. So my access with host-x11 in crouton must fail. But the crouton-developers were busy and built a nice new integration, that is simpler than before and makes use of the Chromium windows.
I’d like to share my first steps to make use of “xiwi”:
First I updated my crouton guest-environment. Instead of “-t x11” I updated to the new target “-t xiwi”:
sudo sh ~/Downloads/crouton -u -n jessie -t xiwi
#It is a Debian Linux (Jessie)
Xiwi has to be glued to the App “crouton integration” which can be installed with one click in the chromium browser from https://chrome.google.com/webstore/deta...nbcgkbijom
I can start an instance of Pianoteq directly from the chrome shell then with:
sudo startxiwi /home/alice/Pianoteq\ 5/amd64/Pianoteq\ 5
A normal window or tab with PTQ inside appears on the chrome desktop. By default PTQ is using chromes integrated audioserver “cras”. Which is nice, so chromes volume-slider can be used as usual (also the symbol-keys).
But … cras is again slower on my Acer than direct hardware access, so I decided to stop the audio server before I start PTQ with ...
sudo stop cras
… and choose the direct soundcard access in PTQ’s devices.
The price is, the cras volume-slider is dead then (of course) and I have to start a separate mixer in the crouton guest. At the moment I simply start a second window with the alsamixer:
sudo startxiwi xterm -e alsamixer -c1
The wonderful Pianoteq v5.3.0 is running again on my chromebook with 48 kHz, 64 samples (1.3 ms).
cheers
