PI4-buster Vs. PI3-stretch

[david_1234]

Hello ,
up until now I run my code on PI3-stretch
wanted to know if there are any changes I need to do in the setting when moving to buster ?

I want to remove the pi icons at startup,diable the black screen after 10 min , show my own logo in boot
this is what I did until now:

Code: Select all

Sudo nano /boot/config.txt
Add this line:
disable_splash=1

Sudo nano /boot/cmdline.txt
Add this to the end of the line 
logo.nologo 

change the image splash.png (with my own image) in
/usr/share/plymouth/themes/pix/

sudo nano /home/pi/.config/lxsession/LXDE-pi/autostart.txt
@lxpanel --profile LXDE-pi
@pcmanfm --desktop --profile LXDE-pi
@xset s noblank
@xset s 0
@xset -dpms
point-rpi
@chromium-browser --start-fullscreen --start-maximized /home/pi//angular-node/src/startPage.html

upload the memory to 1024 in: ---? do I still need to do this? (I'm using PI4 4G)
sudo nano /etc/dphys-swapfile

Thanks ,



****Update****
I have try to run with this setting:
I don't see the 4 pi icons at startup
I don;t see the splash.png image I have uplaoded
and it's seem that this command is not working
@chromium-browser --start-fullscreen --start-maximized /home/pi//angular-node/src/startPage.html

The browser is not open on startup
but if I run the command on the CMD - it's working and my code \webpage is running with out any problem
why?

No. That gave an extra 1GB of swap space providing 2GB in total of virtual memory.
You now have 4GB of real memory!
Its unlikely you will need much, if any, swap for a 4GB Pi4.

OK , Thanks (As I thought - but wanted to be sure)
