Flash DAPlink onto NUCLEO STLink v2

Had a NUCELO-F302R8 around, used it for the onboard STLink v2.
Broke out 'reserved' programming pins (SB4, SB6, SB8 and SB10) for SWD. Connected to STLink v2 clone.
Programmed DAPlink bootloader (stm32f103xb_bl_crc.bin) to 0x8000000 and firmware (0257_stm32f103xb__0x0000.bin) to 0x800C000.
Kept going into bootloader, jumpered 'button' (CN4-pin5 to JP1-pin1).
lsusb shows 'NXP ARM mbed' (okay text bug but works!).
Fired up 'opocd', installed 'nrf52' package.

Serial Console Monitor

To start:

screen /dev/ttyACM0 338400

To stop: <Ctrl> + A then k and yes.
To scroll up/down: <Ctrl> + Escape then up/down arrow to scroll. Escape to exit.

Manual flashing

Upgrading Lenovo Y480 screen from WXGA (1366X768 - HD) to FHD (1920x1080 - Full HD)

Confirmed that Y480 has single-channel LVDC from motherboard, Y580 had dual channel. Cannot just replace LCD with Full HD as its missing controller signals. Bummer.
Find compatible Full HD screen replacement
Find VGA-to-LVDS controller board to fit where DVD drive was located. Remove DVD drive and permanently fasten cover.
Find (slim) VGA cable to solder from motherboard to VGA controller board
How to turn off display when standby, etc?
How to adjust brightness via OS? If VGA output is used, backlight is off. sigh.
Processor has provisions for eDP and second channel LVDS but none are populated.
