Kubuntu 18.04 LTS named Ubuntu in GRUB and tlp-stat
Solution 1:
I have Ubuntu 16.04, Kubuntu 16.04, Kubuntu 18.04, and Lubuntu 18.04 all on my machine. GRUB shows them all as Ubuntu. I know which is which by the sdx information (where x is a number) because I kept track of what was being installed and where.
From /boot/grub/grub.cfg:
menuentry 'Ubuntu'
submenu 'Advanced options for Ubuntu'
menuentry 'Ubuntu 16.04.4 LTS (16.04) (on /dev/sda3)'
submenu 'Advanced options for Ubuntu 16.04.4 LTS (16.04) (on /dev/sda3)'
menuentry 'Ubuntu 16.04.4 LTS (16.04) (on /dev/sda5)'
submenu 'Advanced options for Ubuntu 16.04.4 LTS (16.04) (on /dev/sda5)'
sudo fdisk -l also doesn't reveal the flavor:
$ sudo fdisk -l

Partition table entries are not in disk order.
And neither is sudo parted -l helpful:
$ sudo parted -l
Model: ATA TOSHIBA MQ01ABD1 (scsi)
Disk /dev/sda: 1000GB
Sector size (logical/physical): 512B/4096B
Partition Table: gpt

But /var/log/installer/media-info should reveal the flavor you've currently booted into:
Kubuntu 18.04 LTS "Bionic Beaver" - Release amd64 (20180426)
I doubt that entries in GRUB affect the performance of TLP.
