I believe the problem is the support of your nVidia video card (you have an
nVidia video card, right?):
Sep 1 23:58:30 GNU kernel: [ 0.875020] nouveau E[ VBIOS][0000:01:00.0]
0x75f2[ ]: unknown opcode 0xb9

You may actually have text sessions working. Let us see. After the init, a
few tens of seconds after the screen goes blank, type Ctrl+Alt+F1. If a
screen asking for you "login" is displayed, then you can input your login
"ron", then [Enter], then your password (it is normal not have any graphical
feedback) and finally [Enter]. Then, you can try to update your kernel
following the instructions on https://jxself.org/linux-libre/
But a probably better idea would be to physically remove the video card: your
Intel processor has a graphical chipset that Trisquel perfectly supports.
