Every time I boot my PC...
After I enter another F2 terminal I can log in text mode, but the graphic mode does not start, I uninstalled SNAPD and it only gave me the error of the first line, the second, "Dev loop15..." disappeared, but the system still does not boot in graphical mode.
I have a (sda SSD, a1 UEFI,a2 SWAP,a3 root, a4 HOME and sdb HDD

A few queries:
Is the machine set to boot to GUI?
Run in the terminal:
Code:
systemctl get-default
To be set to boot to GUI the output should be: graphical.target.

Check to see if the machine thinks firmware is missing. You may need to run this as root.
Code:
dmesg |grep -i firmware

Does the machine have the amd firmware installed?
Run in the terminal:
Code:
apt list --installed | grep -i firmware
The output should include: firmware-amd-graphics.

Does the machine have the relevant driver installed, (assuming it's running X)?
Code:
apt list --installed | grep -i xorg-video
The output should include: xserver-xorg-video-radeon, xserver-video-amdgpu, xserver-video-ati.
 
Same issue for me...
I'm new to ubuntu, how did i launch the terminal when starting the pc ?
