1) Don't use LaptopModeTools, its pretty much been abandoned. Everyone's moving/moved over to TLP.

PowerTop uses ncurses, I suppose that even with --auto-tune, it's trying to init ncurses, which fails without terminal (real or faked by $TERM).

A true energy management system
If you want to intelligently manage energy / performance / responsiveness of the system and hardware resources, it is proposed to install Our NeteXt'73 and install my solutions: one of the kernels - appropriate for the architecture, scripts managing energy and efficiency = APM and make appropriate entries in Grub, and also install the latest Linux firmware / microcode. Below videos of the action following system:
Notebook - MSi X370:
APU AMD E-350 (1600 MHz),
GPU: Radeon 6310,
RAM: 4 GB DDR3
enegią management: APM 3.4, entries in Grub, Linux-firmware/amd microcode,
Drivers: Catalyst 14.4 [stable].
You can see how the system works by using profiles of performance-ondemand and performance-conservative - for APM. In the movies you can see how my APM gradually "quenches" individual devices and a decrease of energy consumption.
aha another important piece of information - while working on the battery practically everything in PowerTOP will be on Good [on AC everything will be on the 'Bad' - intentionally = full power of the machine] - almost as certainly 'VM writeback timeout' will be 'Bad' - here is my purposeful = value proposed by PowerTOP I consider "inappropriate". In addition, a certain portion of energy saving systems WiFi does not work - hence be 'Bad' = disabled functionality in the driver sources [Developers driver turned off] or the lack of such functionality at all. This works for sure in part Realtek drivers, Atcheros or all of Intel's ... well, unless you switch it off this functionality by NeteXt'73.

Which begs the question, which parts of the stack are to blame for users needing to install those 2 rather than have things working automatically ?
