The new generation powerful RPI 5 is reviewed in this video. The new hardware , new OS Bookworm and the new Desktop display WAYLAND.
The Display window system in Bookworm OS is using WAYLAND ( X11 in BullsEye).
USB C power official is now 5v 5amp (27w).
Built in RTC and a connector provided to add battery for RTC.
Between 2 micro HDMI ports is a single UART connector. You need a Raspberry PI PICO Debug kit for debugging.You can also make UART connections to other microcontrollers.
3.5mm composite jack is not there.For composite video you can use the VID pins .
CSI - Camera Serial Interface connectors are now 22pin smaller size.This is similar to the one in RPI ZERO. You can now connect 2 cameras or 2 DSI displays or a mix of both.
USB & Ethernet ports are swapped compared to RPI4.So you need a new casing for RPI5.
Casing with Fan and heat sink recommended.
40pin GPIO remains the same as old.There is a new silicon chip RP1 to handle all I/O operations including GPIO,USB,Camera connections,etc.
Another new interface is for PCIe devices. NVMe drives are supported. M2.HAT required to connect these drives.
Power button is introduced.Soft button .Press once for shutdown/logout menu.Another press will trigger safe shutdown.Another press will start the RPI5 up.
Remote desktop blue screen or graphical issues can be solved by adding a new user.
sudo adduser newuser
//grant the user sudo permission
sudo usermod -a -G sudo newuser
another solution is to add group ssl-cert to xrdp user.
sudo adduser xrdp ssl-cert
sudo nano /etc/x11/xrdp/xorg.conf
look out for Option " DRMDevice" "xxxxxxxx"
and change it to Option "DRMDevice" " "
