Hello ! And thank you for your suggestion. I had no cmdline.txt in my /boot directory. I created one based on a pi filesystem containing : dwc_otg.lpm_enable=0 console=tty3 root=/dev/sda1 rootfstype=ext4 elevator=deadline fsck.repair=yes rootwait splash quiet plymouth.ignore-serial-consoles logo.nol...

Thanks, Well I have the same version. I searched for any other splash.png or similar size file on the system, and nothing... /usr/share/plymouth/themes/pix/splash.png seems to be the source. It seems the splash screen is compiled in plymouth or something like that. Is there something else to perform...

Thank you, but did you try that on the latest Debian Stretch ?
I just tried, and I get the same result as before. I still got the "Welcome to raspberry pi desktop" splash screen, not my new image.

Hello,

I'm using the latest Rasbian x86.
I changed /usr/share/plymouth/themes/pix/splash.png with another 1024x768 png image but it does not change the startup splash screen at all.
Did I miss something ?

Thanks in advance for your help !
