  Manjaro w/ Panfrost Drivers vs stock Debian Video Performance
Posted by: decisivedove - 03-01-2020, 11:37 PM - Forum: Linux on Pinebook Pro - Replies (15)

Hi,
I was just wondering how the video performance i.e. YouTube, Netflix, playing video files, games, etc. compares between Manjaro with Panfrost drivers and stock Debian. Also if anyone has played supertuxkart on the PBP, what graphics settings and FPS can I expect.
Thank you!


  How to switch to OTG from usb-network?
Posted by: ptoki - 03-01-2020, 10:57 PM - Forum: General Discussion on PinePhone - No Replies

I am playing with pinephone and somehow its stuck with usb0 as network device attached to usb connector. I want to use mouse and keyboard and be able to switch between those two modes.

How do I do that?

PS. I think i had the OTG cable working once but now both my distros (MATE and XFCE) are stuck with usb-net.


  Not charging via barrel plug anymore
Posted by: LutzFechner - 03-01-2020, 04:32 PM - Forum: Pinebook Pro Hardware and Accessories - Replies (1)

Hi,

my PBP stopped charging via the plug a few minutes ago.

Battery is now at 89%.

Voltage on the Adapter is 5.39V.

Charging via USB still seems to be fine....

Anyone else has this or knows how to fix that?

Just not for me guys, make me an offer its sat in the box since day three of owning it. Has the m.2 adapter installed and comes with the usb programer also.

I am in the USA.

Whatever I do, I can not login to my Google Account with Chromium on Pinebook Pro.

"Less secure apps" is on.

Firefox works so far.


  Optimizing Wifi
Posted by: gleachkr - 03-01-2020, 02:27 PM - Forum: General Discussion on Pinebook Pro - Replies (13)

Hi Everyone,

How's your wifi performance? I'm interested in figuring out what the maximum is, and what kind of access point is going to work best with the pinebook pro.

Please post iperf measurements, ideally within LAN, and details of your wifi setup.

I'm getting 20.5 Mbits/sec to a wired machine on my LAN, using the 5Ghz band and a  NETGEAR C3700-100 router.  I'm sure you can do better than that!


  How I am running ubports as a daily driver
Posted by: tahayassen - 03-01-2020, 12:35 PM - Forum: UBPorts on PinePhone - Replies (11)

1. Write ubports image to emmc
2. Extend root filesystem to 16GB as per https://askubuntu.com/a/958145

Code:
sudo parted /dev/mmcblk2
  resizepart 1
  yes
  -0
  quit
sudo resize2fs /dev/mmcblk2p1

3. Wifi work-around.


Code:
nano /home/phablet/fix-wifi.sh:
sudo nmcli radio all off
sudo rmmod 8723cs
sudo modprobe 8723cs
sudo nmcli radio all on


Heart Getting Started: Maemo Leste - Devuan / Debian distro for your PinePhone
Posted by: buffer - 03-01-2020, 11:47 AM - Forum: Maemo Leste on PinePhone - Replies (1)

Did you know Maemo Leste is Debian for your PinePhone? For real! Big Grin  It is Devuan with the arm64 architecture running on stretch. They will soon be upgrading to buster and supporting both Debian and Devuan simultaneously. They use automation in their package maintenance with jenkins (similar to debian's buildd) to ease porting and updates. Porting packages to Maemo Leste is basically a simple matter of porting to arm64 version of Debian, which benefits both projects. So you will pretty much have all the benefits of the Debian repository, especially as the project matures. In addition to the main repositories, there is a community repository (so, like AUR).

There have been a few parallel attempts to port Debian to the ARM architecture, Maemo being the longest running. Currently, the project for porting Debian to arm and arm64 is unmaintained. You might be wondering, why hasn't this been done sooner? Simply put, everyone has been relying on the Android kernel, so benefits are not making it back to Linux. However, there are a few more projects for Debian on ARM (mainly ARM64) including PureOS, Dragonbox Pyra, Armbian, and Debian + phosh, so that's about to change rapidly.

Most discussion about Maemo occurs on their website and platforms, go here for an updated list of links. There is an ongoing thread about Maemo Leste for the Pinephone.

With volunteers we can easily test and get it to a stable condition on the PinePhone, so I compiled some useful links:

  Battery life and ways to improve - request for official statement
Posted by: p1trson - 03-01-2020, 09:18 AM - Forum: PostmarketOS on PinePhone - No Replies

Hello folks,

so far I didn't see any official statement why the battery life is so poor and whether there's anything to try/test to improve it. This should be the top priority imho! Observations:
- it's always top of the phone which gets hot (where the modem is located).
- touching the uncovered modem my guess would be between 55-65C all the time. This higher heat from the modem can be felt also on the screen side
- pmOS with plasma-mobile is way cooler based on my tests today than the Phosh image (tested today with latest images, no SIM)
- checking the CPU frequencies seems to be ok, however the lowest frequency seems to be high imho, is this due to hw limitations ? Trying to set the available frequencies to be lower didn't do the trick

Code:
  current CPU frequency is 648 MHz (asserted by call to hardware).

  cpufreq stats: 648 MHz:73.58%, 816 MHz:3.03%, 912 MHz:0.67%, 960 MHz:0.54%, 1.01 GHz:0.60%, 1.06 GHz:0.57%, 1.10 GHz:0.84%, 1.15 GHz:20.17%  (4271)

- is there any way to exactly track what is eating up the battery ?
- is the a known method to reduce power usage siginificantly ?
- is there any supported way to measure the temperature of various components in alpine linux ?
- why is the modem so hot even though I have no SIM inside the phone ?

Cheers!


  pip install not working -- Manjaro
Posted by: User 15552 - 03-01-2020, 08:21 AM - Forum: Linux on Pinebook Pro - Replies (2)

Hi, 

I recently switched my pinebook pro to Manjaro. Everything seems good so far. 

But I cannot install the scipy package via `pip`. After installing Blas and some cmake stuff I got it to install numpy via `pip install numpy` but scipy  still does not work. I know that there is a python-scipy package that I can get via pacman but I was wondering why `pip install scipy` does not work. 


At first it crashed because of memory issues, but I set up swap as described here and it worked. However it still will not work -- output below . What is `ld` and what is `collect2` and does anybody understand what is going on? 

Some of the output:
