I recently dualbooted my laptop (Huawei matebook x pro i7-8550U, 16ram, nvidia mx150) for the first time (Ubuntu 19.10). I had few problems with it but i managed to resolve all of them expect the battery performance. On windows my laptop works for ~9h and on linux less than 3h. I have read that battery on linux should last longer and and on my perticular model even up to 11h. Any solution? Thanks in advance!

On the occasion, 4 more problems:

  1. Fans are often running for no reason.
  2. Performance is no as good as I expected, my specs are more than capable and still Ubuntu performs poorly.
  3. Fingerprint GUI doesn't find my fingerprint reader.
  4. Ubuntu doesn't remember my resolution and position of second screen, I have o set it manually every time I plug it in.

DRIVERS:

$ lspci -k | grep -EA3 'VGA|3D|Display'

  • What driver are you using for the Nvidia GPU? If you don't know how to check it just open a terminal and run lspci -k | grep -EA3 'VGA|3D|Display'. Then edit your post with the output. Commented Feb 24, 2020 at 16:55

For now let's try with the GPU driver. Nvidia works a bit different on GNU/Linux compared to windows. First install the Nvidia official drivers. Open a terminal and run ubuntu-drivers devices. It might take a while. You should get a list like this one:

$ ubuntu-drivers devices == /sys/devices/pci0000:00/0000:00:1c.0/0000:01:00.0 == modalias : pci:v000010DEd0000174Dsv00001025sd00001218bc03sc02i00 vendor : NVIDIA Corporation model : GM108M [GeForce MX150] driver : nvidia-driver-440 - third-party free recommended driver : nvidia-driver-390 - distro non-free driver : xserver-xorg-video-nouveau - distro free builtin

So, let's focus on the recommended driver. In this case is nvidia-driver-440 - third-party free recommended (You should get that one too). Open a terminal and run sudo apt install nvidia-driver-XXX (Replace the XXX with the number you got before. When it's done just reboot your laptop. (In this case it would be sudo apt install nvidia-driver-440)

Once you log in again you should have a new desktop app called Nvidia X Server Settings. There is where you can set up your Nvidia GPU. (Similar to Windows).

Now we can work on the the really important thing: battery performance. On the Nvidia X Server Settings you should get an option called PRIME Settings. (If you don't, simply install it running sudo apt install nvidia-prime). There is where you can select what GPU you want to use. For a better battery performance select the Intel GPU, then reboot your laptop.

After all this process it's normal your laptop fan is turned on. Rebooting, installing drivers and the Nvidia GPU heats up almost any laptop. Just leave your laptop alone some time so it can cool down a bit.

If you want to know your laptop's CPU temperature install lm-sensors by running sudo apt install lm-sensors. Then run the command sensors.

Please let me know if this has been useful to you.

Regards.

  • Thanks a lot for you afford, I really apreshiate it! Unfortunately it didnt help, after following the instructions the laptops shows 2,5h of battery life with 90%. The only thing that differed was the Nvidia X Server Setting options, on the list I can only see PRIME Profiles not PRIME Settings, although in PRIME Profiles there is "Select the GPU you would like to use" and i selected Intel (Power Saving Mode)

  • A thing that comes in pair with poor battery life is that it charges very slowly, I though it might help

  • Aslo, i think the problem with fan turning on lies deeper, it turns on while watching youtube video

  • Fine, now install tlp running sudo apt install tlp. Basically tlp helps to extend battery life without any further setup. After you install it reboot your laptop. Please let me know if it helps. Commented Feb 24, 2020 at 20:45
  • Usually high quality video heats up a bit the GPU, so the fan is turned on at slow speed. Commented Feb 24, 2020 at 20:47
