While researching what seems to be Manjaro specific extremely low performance on battery problem
i believe i’ve found power-related bug which is universal to my setup and most likely nvidia driver related, checked it on Ubuntu (which DELL claims to “officially support”) - also happens there.
-
After boot on AC
Heavy load Graphics 1708 mHz / Memory 7230 mHz
FAN can go REALLY hard on any load -
BAT
Heavy load Graphics 427 mHz / Memory 7230 mHz
FAN doesn’t go REALLY hard on any load -
After switchin back to AC
Heavy load Graphics 427 mHz / Memory 7230 mHz
By heavy load i mean games like Native Hitman 2016, 3D modeling, 4k video…Well all the usual stuff that should crank CPU/GPU.
If you just load on AC everything is fine, clocks can go max, but any battery/AC swtich cause this to not recover max performance until reboot.
In short in manjaro thread i’ve tried disabling tlp, powermizer, forcing tlp to full max, forcing powermizer to max etc - nothing changes this behaviour.
So i suspect this bug could possibly be connected with Manjaro performance problem, but after trying Ubuntu i guess this is separate nvidia driver related issue.
Now i’m on clean Manjaro Deepin, updated and installed latest Nvidia 415.27

I’ve repeated above steps 1-3, then sudo startx – -logverbose 6 and nvidia-bug-report.sh
P.S. If anyone have any suggestions and help in original Manjaro thread considering performance on battery, which accidently have lead to finding this one - please feel free :)
