Initial Setup Q's and Some Doc Feedback

ember1205

Thanks… Good updates. I will definitely look through your updated installer.

With regard to the warnings - I understand what you’re saying, but my concerns were driven more by the warnings that said “this might not even work.” I realize that they may be very specific to certain aspects, but given that isn’t indicated specifically, it raised up my alert level.

On the fake versus real driver piece, I did notice the “f” to indicate the fake driver. With zero experience with this piece, and having no background that there IS a fake driver or that it’s now default, my eyes told me that the name for the fake driver was actually the name for the real one at first [two] glance[s]. It wasn’t until I reached the latter part talking about the fake driver that I realized it was a different name and changed it.

I’m not using portrait mode as I want this to be a “Magic Photo Frame” and display pictures (many of which are in landscape format), so it seems that I might be able to use either.

Backing up just a bit, there appears to be no guidance in the install doc as to whether I should choose to allow the installer to set MM to autostart and/or whether I should disable the screensaver during the install process. I chose “N” and “Y” respectively.

that is all really choice on your installation and and usage planning…

i don’t want to touch the mirror… if it reboots cause of power outage, etc, I want it to logon, and start mirror, and never screen lock…

so, set OS to auto logon (manual step)
use pm2 to autostart
and turn off screensaver

Yes. Those were all done. But, the screensaver disable was done during the install and it appears to not have modified the same files as the manual changes show.

@ember1205 i didn’t set the OpenGL driver… not worth the hassle. the driver is REALLY useful for algorithmic objects, rotating in 3d… nothing we do on the mirror

hm… i didn’t update the doc for manual install for my new installer… there are just too many places with different solutions…

I embodied all that I know about and generalized to attempt to cover more as time goes on.

@ember1205 There are three locations where the screensaver might be starting from, and only one of them is actually run (I believe the first found in this order):

/home/pi/.config/lxsession/LXDE-pi/autostart
/etc/xdg/lxsession/LXDE-pi/autostart
/etc/xdg/lxsession/LXDE/autostart

Raspbian recently changed to not having the first one, so the second is now the preferred method.

@dsegel thx… already in the updated installer and the screensaver fixer scripts

So… None of that works. The ONLY way I could get the screensaver to shut off was to do:

sudo apt install xscreensaver

And then run the Screensaver Preferences setup and set it to disabled. Anything else I tried ultimately allowed the screen to go blank (black) after about 15 minutes.

sdetweil

@ember1205 thanks… I wished we had worked on it a little more…

i have a script that just does setting screensaver off…

haven’t had it fail on anything in a while… just tested Zorin OS. it worked properly

I’m going to try a fresh build and will use your script to see how it fares on this exact version of Raspbian…

sdetweil

@ember1205 k… let me know

ember1205

I have started my new build from scratch and used your install script.

There are a number of ‘vulnerability’ warnings that show, and I’m curious if I should actually try and repair them with the suggested npm commands or not.

Also, so far, the screensaver does seem to be disabled, but I haven’t yet jumped into the MM configuration to put in place the same modules I had been using on the other setup as of yet.

sdetweil

@ember1205 yes, the vulnerability warnings are troublesome… they usually cannot be all resolved, and some modules fixes force changes that break applications using them. i prefer NOT to attempt to resolve the problems…

screensaver…

can u show/send me the ~/install.log

my email is the same userid as here on gmail

Some additional notes:

The screensaver settings appear to have been set in the /etc/xdg/lxsession/LXDE-pi/autostart file
No settings have been adjusted in /etc/lightdm/lightdm.conf
The mouse pointer auto remove configuration has not been completed, but there appears to be no issue with the pointer remaining on the screen once Electron loads
There was no change made to the system to disable power saving on the WLAN interface - as a result, the interface seemingly “could” go into powersave mode and affect network connectivity (I have not yet experienced an issue with this)

sdetweil

@ember1205 cool. great feedback.

i dont have lightdm changed on my buster system.
according to this, its still lxde
https://www.raspberrypi.org/forums/viewtopic.php?t=249837

correct, there is no mod for mouse pointer.
can also be done in css
cursor: none;

also no setting change for wlan power

ember1205

@sdetweil

-Should- the WLAN power setting be changed? It would seem that this would be a wise approach to ensure it doesn’t go into powersave mode.

sdetweil

@ember1205 i don’t know the answer… depends on how much its used I would guess…
I don’t know what the power save rules are

ember1205

@sdetweil

I believe the rules are less important than the consequences. I don’t believe WLAN has a good track record overall of waking up from a sleep state. And, regardless of how much it’s directly used, you can bet that the one time it won’t work is when you try using the remote control module to power it down. :)
