DWC on SBC question

chas2706

Does anyone know if I can change the behaviour of the DWC window so that it is opened in window mode like this:

I want to be able to access the desktop taskbar and display the DWC window upon boot.

Thanks in advance.

Edit: tl/dr sudo sed -i 's/ --start-fullscreen/ #--start-fullscreen/' /usr/bin/launch-dwc should take care of it with a one-liner

Thats soley handled by Rasbian; I've not tried the full desktop image but poking around DuetPI on github it may suggest you can do

sudoedit /etc/xdg/lxsession/LXDE/autostart

and put a # infront of launch-dwc on the last line?

(if sudoedit doesn't want to edit the file do sudo nano /etc/.../........)

Yes thanks for that but the problem is the way that the window is displayed full screen on start up.

The standard built in raspbian close,lower and minimise window icons are not available and you have to hover over the top, middle area of the screen to bring up an "X" which then allows you to lower the window. The problem I have is that on the SBC touchscreen it is very hard to get the "X" to appear so preferably I want the standard window icons available.

What you are suggesting will just stop the window loading on start up but then after loading it manually it will still open the same way without the window icons.

@chas2706 if you run launch-dwc it will run the same setting, but if you launch chrome on your own it should be okay?

I have just tried that and found out that it must be something to do with the chrome browser because it opens in exactly the same fashion, without window icons and you close it by hovering at the top and clicking on the "X" that then appears.

Thanks for your great suggestion though.

thats odd; looked like its just being run in full screen mode (F11 on keyboard to toggle?) but seems odd that chrome should launch in full screen mode when not launched by the launch-dwc script that specifies --start-fullscreen

need to set up another Pi soon I'll see if I can download the full image before then

You can just place a short cut to the ip address and it will open in a standard window had the same issue...
apparently changing the resolution of the screen and when asked to accept or revert selecting revert has fixed this on some installations may be worth a try but the ip link does work

How do I create a shortcut to the ip address?

Open chromium enter the Pi ip 192.xxx.xx.xx
save as a favorite add to tool bar
Also hitting F11 exits full screen mode or touch screen hold finger on screen for couple seconds and Exit full screen with appear

Great. Thanks for that.

as dwc is running on the same host using http://localhost/ would make more sense and not be dependant on user networks which may differ from 192.168/16

if exiting full screen works then find launch-dwc and remove --start-fullscreen. if that doesn't work toggle overscan settings in raspi-config?

chas2706

Thanks both of you.
All sorted now.

would you mind sharing, others may find the thread useful later?

Just making you aware that when I edited autostart in /etc/xdg/lxsession and put a hash in front of @launch-dwc, when I rebooted I found that DWC still autostarted.
In my duetpi image there is another autostart found in /home/pi/.config/lxsession/LXDE/autostart.
It has exactly the same content as the other one in etc/xdg/lxsession but this MUST be the one the pi is looking at. Hashed out in here and DWC does not autostart.

Also I found a quicker solution to my problem.
In chrome I set the home page as duet3.local/ then in /home/pi/.config/lxsession/LXDE/autostart I hashed out @launch_dwc and added @chromium-browser.
Now on startup I have chrome autostarting in windowed mode and connected to DWC.

chas2706

Here's a copy of the new autostart file:

@lxpanel --profile LXDE
@pcmanfm --desktop --profile LXDE
@xscreensaver -no-splash
@/home/pi/./atx_on.sh
#@launch-dwc
@chromium-browser

Once again, thanks everyone for your help.

huh, interesting, and redundant. wasn't clear from the DuetPi repo, but admittedly not familiar with pi-gen at all.

if fullscreen was the issue I'd lean towards editing launch-dwc and commenting out --start-fullscreen from there, then it works even if you add another user, change windowmanager or whatnot.

sudo sed -i 's/ --start-fullscreen/ #--start-fullscreen/' /usr/bin/launch-dwc should take care of it with a one-liner

Not so, because @launch-dwc does not have the extra --start-fullscreen parameters in it!

it should

(and mine did)

chas2706

Sorry, I was looking in the wrong place!
Going to try that now.

chas2706

You are a star.

Commenting out --start-fullscreen works and has the extra benefit of no page tabs or search bar so you basically get full screen but with the window control buttons.
Cheers.
