"Must have" IceWM Desktop Shortcuts for J720 Devuan

Those of you fortunate enough to have a Jornada720 ...with a working installation of Devuan Linux that runs the IceWM window manager... may find these shortcuts wonderfully useful (as I have).

1. Change desktop/workspace:

ctrl + alt + arrow key (left or right)

2. Move highlighted window to different desktop:

ctrl + shift +alt + arrow key (left or right)

3. Toggle highlighted windows/apps on a particular desktop:

alt + tab (repeat as needed)

4. Open new primary terminal window (slow):

ctl + alt + T

5. Open new separate secondary terminal window (fast) :
ctl + shift + n

6. Open new separate "Tabbed sub-window"in a highlighted open terminal window (fast):

ctl + shift + t

7. Bring up main menu:

crtl + esc

8. Bring up window list:

ctl + alt + esc

9. Open Jornada-config if installed :

sudo sh /opt/jornada-config/jornada-config

(if from root level gives initial setup menu

if from user level gives working menu AFAIK)

There you have it, although I will be adding more to this list in time. The top few and botton one are my most useful. There are numerous tricks and tips to follow along on this and how to's if things lock up, or wifi won't connect via connman, using VNC or Firefox, etc.

As some of you may know, my primary goal has been to automate/simplify installing and running Stefan's great Devuan port for the Jornada720.

I started by creating easy to install disk images leading to the manual log in screen. This then required manually typing "startx" to bring up Fluxbox desktop. (Thanks to ArchiMark the more sophisticated IceWM was later substitued).Many open source apps have been included both from Stefan's tar image and by my own efforts for file management, image viewing, file transfer, etc., improving the devuan experience.

As my understanding of Debian/Devuan/Linux grew, I learned how to automate log in so that devuan boots directly into the IceWM desktop (aware of some folks security concerns, this can be disabled.... Thanks to Timob0's amazing Jornada-config app).

Most recently, I have added a startup script that starts the battery monitor, brings up the main menu, and automatically opens a colorful scrolling LXterminal window so everything is ready to go and at your command after the 2 minute boot time.

Finally, I have learned to automate ssh login to a RasPi (or any Linux computer) by exchanging security keys. Using a command in terminal such as

 ssh pi@your.RasPi.ip.address  -X firefox  

will automatically log you onto your RasPi(or other) and start up firefox! Eventually a scripted entry will be placed in the main menu so that a single click will do this.

So, I will be covering in detail the steps to take to make this work... in a future post... hopefully soon. Anyway, that's the game plan!

Automating ssh login is quite easy:

1. Open a terminal window on the Jornada 720 and enter:

 ssh-keygen -t rsa

it takes a few seconds to generate the encryption private/public keys, saved to the default /.ssh location, key password is optional(if used is asked for only once per session).
2. Copy the public key to the remote host (RasPi with ssh enabled for example) from your Jornada720 terminal window with this command:

  ssh-copy-id -i /home/user/.ssh/id_rsa.pub  pi@raspi.ip.address

That's it!

Now, I am definitely not recommending using this simple Jornada/RasPi setup for any Mission Critical tasks... since security is limited to WPA wifi and the ssh key lacks the password security. Use your laptop or other secure device for mission critical security level. This is fine for casual net surfing, etc.

Ahhh, once again I return to my "echo chamber" here at HPC:Factor!

I recall that thread back in ? 2005 and that fellow posting for months trying to get Linux to work on the Jornada 720... 90% of the time he's talking to himself or so it seemed to me re-reading that "locked thread" yet he was quite the trailblazer and now his dream is very real, even if it took over a decade and a half to bring his efforts to fruitions.

And in that spirit of his... I carry on sharing the excitement of each new nugget of gold i discover. Fools Gold perhaps... but no less precious to me, IMO, and you lucky souls get the chance to share in it! Torment or not included

The auto-ssh login is really slick! Months ago I described in another thread how it used to take what seemed like 30 steps, multiple ID and password entries in fluxbox, etc to get internet browser access... ugh! seems like light years ago, well not quite as that is a measure of distance not time... ok the distant past...

FYI, I prefer to auto-ssh right into Firefox browser because Real VNC viewer requires extra steps to maximize and then select your host (although it does bring up the complete desktop... not just a browser as with firefox.

Another advantage of Firefox is the "ctrl + up arrow" takes you to the top of the page, whereas "ctrl + down arrow" speeds you to the bottom where you often find the option for the desktop version of the webpage instead of the mobile version, for example with wikipedia or audible.com. something not available with Chrome browser. It's really snappy too!

Firefox opens in it's own X-forwarded window, whereas the newer stock RasPi chrome browser requires the full vnc desktop (older versions of RasPi Chrome if you can find 'em used to open in an X- window).

Further, Firefox is easier on the cpu and wifi power consumption so browsing/blogging for 3 hours with WPA wifi card can be the norm (more like 2hours with VNC full desktop.
You can see the difference in the cpu and network meters showing on the IceWM taskbar).

Later, I will review the keyboard shortcuts for both, such as "ctrl +" and "ctrl - " to resize text and images (basically Zoom in or out)works for both browsers and is very handy... especially when trying to click on that tiny "edit" button (not that I ever need to use it).

I am always amazed how readable the tiny fonts are on the Jornada screen... somewhere near 21 lines of text! Great when viewing those rainfall weather tables, integrated circuit data sheets, etc.

The saga continues.... more later, my friends...
