I have just assembled my freshly received DevTerm (RPI-CM3) but at startup, the top menu bar from the main interface does not show.
A white rectangle thing did flash a few times at the expected location of the bar at startup (and during the initial update phase), but disappeared after 5 seconds.
I ran the update, restarted the system a few times after a full power cycle, it looks operational (although I cannot do anything else than moving the bin icon on the desktop).
I manager to access the console with Ctrl+Alt+Fn+F1, did not see anything really exciting in log messages.
I usually use command line only so I am not familiar with window managers, and I don’t really know where I should be looking for error messages to understand what could be going on.
Unfortunately my device is not really usable without a menu bar here.
Would anyone have a tip to share with me?
Thank you for your suggestion, it does open a menu indeed, I can access the menu bar parameter and ask for it to be shown at the bottom of the screen instead of top: after a reboot, the white bar flashes at the bottom of the screen, not the top, but that’s it
I managed to get some insights from the log file “/home/pi/.cache/lxsession/LXDE-pi/run.log”
Which brought me to this thread: https://www.raspberrypi.org/forums/viewtopic.php?t=148030
I am getting the exact same bug, unfortunately all 3 suggested solutions (that work for other users) are already implemented by default, so… I will have to look further.
Any recommandation would be welcome, I will update the thread if I find a solution!
Thank you guu -
I did try the solution you submitted (removing lxpanel config file) - unfortunately the problem still happens.
I will try re-imaging the sdcard. Will keep you posted!
Thanks
Thanks a lot - I ran into that as well, but it didn’t help.
But good news, I finally solved it.
How I found out :
Launched a terminal (Ctrl-Alt-T)
Launched “lxpanel” → I got a menu bar displayed, but a few error messages, and it was broken (mostly because the logo was missing for the main button).
Launched “lxpanel -p LXDE-pi” → I got this in the STDERR:
** Message: 17:56:17.285: x-terminal-emulator has very limited support, consider choose another terminal
grep: /home/pi/.config/lxpanel/LXDE-pi/panels/*: No such file or directory
** Message: 17:56:17.899: Connecting ...
** Message: 17:56:17.900: Status changed to down
** (lxpanel:7758): CRITICAL **: 17:56:17.901: dhcpcd_open: Resource temporarily unavailable
Unit pt-device-manager.service could not be found.
The missing service is interesting here:
I then ran apt install pt-devices, restarted the device, and now it works!
@lawi I made an account just to thank you. Got mine in yesterday, put it together last night. I was just sitting down to figure out how to fix my missing menu bar problem and saw your post.
So I had this same problem for my first day of owning my DevTerm while I waited for my batteries to come in. Finally after installing the batteries, the top menu finally loaded.
I believe the battery monitor panel fails to init, thus causing the whole menu to fail to load.
TL-DR; If your menu isn’t loading, are you running without batteries? Try with batteries installed.
I would like to confirm DrRacoon was right, the problem is caused by using the DevTerm without batteries
Although installing the pt-devices package allows the menu bar to gets displayed without batteries - it also prevents the battery status indicator to be displayed, as Glbr_Hanson mentions in another thread (The battery/power indicator doesn't show up)
So I would advise readers of this thread not to install pt-devices as I recommended earlier. Just install batteries
Same issue…
