  Wifi doesn't work correctly
Posted by: Fredric92 - 12-28-2020, 04:56 AM - Forum: Linux on Pinebook - Replies (1)

I use the default Linux image, and everything's updated.
After using it for a while, the wifi stopped working properly, requiring me to 'ifconfig wlan0 up', and if that doesn't work, reboot the machine. I am using employee monitoring systems, but even if I disable it, it doesn't help. If I have it plugged into AC power with the power supply adapter, I'll only get 10 minutes to watch fullscreen 720p Youtube before the wifi goes out. I checked the Syslog, and I see a bunch of wifi-related errors when this happens - lots of assert failures, a note saying the chip has hanged, and it shuts off the wifi.
Does this happen to anyone else? Is this normal, or did I get a faulty one?


  How to test digitizer
Posted by: InFerNo - 12-28-2020, 03:50 AM - Forum: PinePhone Hardware - Replies (3)

I have a problem with my PinePhone and I would like to test the digitizer.

I am using Phosh on Arch Linux ARM.

It began 2 weeks ago, when the number 6 in the top row wouldn't always register as touched, but 5 and 7 did. Now I feel like I can't touch a column from top to bottom roughly in the center. Also the "send" button in the messaging app doesn't always register, right now I can't get it to work at all while it worked 30 minutes ago.

I notice it on the lockscreen when I have to enter my PIN, when I switch/close apps in the overview, etc.

Is there a way to troubleshoot dead zones in the digitizer, and in worst case scenario, is there a replacement available?


  unusabel sd card --> mmcblk0
Posted by: tommaso - 12-28-2020, 03:07 AM - Forum: Arch Linux on PinePhone - Replies (3)

The 64GB SD card in the system is a mmcblk0, for this reason it is not mounted as a useful storage device.
How it is possible to solve this item?

Thanks, Regards


  "Unable to download updates: The following packages have unmet dependencies:"
Posted by: bitnick - 12-28-2020, 02:45 AM - Forum: Mobian on PinePhone - Replies (13)

Since a couple of weeks I cannot update Mobian on my Pinephone UBports edition.

Software -> Updates -> Download fails with "Unable to download updates: The following packages have unmet dependencies:" shown in a dark pop-up.

Any idea how to troubleshoot this? Should I do a console update + upgrade instead?


  Can't start zram
Posted by: 3x5co - 12-27-2020, 11:45 PM - Forum: Mobian on PinePhone - Replies (2)

I followed the instructions on the Tweaks page of the Mobian wiki, to install zram. However, when I run 'sudo zramswap start' I get these responses:

```
Dec 27 23:28:39 mobian: Starting Zram
/usr/sbin/zramswap: line 53: echo: write error: Device or resource busy
Dec 27 23:28:39 mobian: Error: setting compression algo to lz4


```

How do I resolve this?


  Whatsapp in Anbox
Posted by: scott_VYuCAbn3k1NFK - 12-27-2020, 09:59 PM - Forum: Mobian on PinePhone - Replies (7)

Hi,



I know this topic has come up a few times. I have been experimenting with Anbox - I've followed these instructions https://wiki.mobian-project.org/doku.php?id=anbox. I then downloaded the whatsapp APK from the whatsapp website.



It installs fine using adb, but then whenever I run it I just get this:


[Image: ?u=https%3A%2F%2Fi.ytimg.com%2Fvi%2FIiPV...f=1&nofb=1]


Has anyone been able to get this working?



I'm also finding battery life to be (anecdotally) generally poorer with anbox services running - it seems to interfere with the phone deep sleeping.


  MTP Services Mobian
Posted by: exhoplex - 12-27-2020, 09:25 PM - Forum: Mobian on PinePhone - Replies (10)

I broke MTP, does anyone know what service I need to fix on the phone or check?

Thanks in advance, I will continue to google, as I am not an expert on MTP server services for Debian.

I found lots on how to connect a phone to debian but not much on how to actually serve up MTP.

Regards,


I found this , I think I am getting close

  Crust weirdness
Posted by: 3x5co - 12-27-2020, 06:26 PM - Forum: Mobian on PinePhone - Replies (4)

I tried to installl caffeine today by running `sudo apt install caffeine`. I got this error message:

```
md5sum: /usr/lib/crust/scp.bin: No such file or directory
E: Sub-process if grep -qE '(u-boot-sunxi|arm-trusted-firmware)'; then touch /tmp/upgrade-uboot; else md5sum /usr/lib/crust/scp.bin > /tmp/crust.md5; fi returned an error code (1)
E: Failure running script if grep -qE '(u-boot-sunxi|arm-trusted-firmware)'; then touch /tmp/upgrade-uboot; else md5sum /usr/lib/crust/scp.bin > /tmp/crust.md5; fi

```

After this, I couldn't installl anything without getting the same message. So I ran the following:

```
sudo mkdir /usr/lib/crust/

sudo cp /usr/bin/scp /usr/lib/crust/scp.bin
```

Now everything works, but this is a hack and I'm not sure what went wrong here, or how to fix it properly. Thoughts?


  Spurious headphone detection interrupts
Posted by: dsimic - 12-27-2020, 06:22 PM - Forum: Pinebook Pro Hardware and Accessories - Replies (52)

Hello,

I have observed generation of spurios headphone detection interrupts on my second-batch PineBook Pro.  The interrupt count increases with no headphones being plugged in or out, which is obviously not the expected behavior.  I have also verified that music playback through internal speakers does not cause the tnterrupt count to increase.

You can check the above-described interrupt count by running something like this:

Code:
cat /proc/interrupts | grep Headphone

This is what I get as the output for the command above, after about six hours of uptime:

Code:
73:   6   0   0   0   0   0   rockchip_gpio_irq   8 Edge   Headphone detection

Of course, there should be a total of zero interrupts generated, instead of six as visible above.

I already looked at the PineBook Pro schematic, board DTS file, and the ES8316 driver in the Linux kernel.  However, I'd refrain from spending a lot of time digging into this, until we can establish it as a known, non-isolated issue.

Could anyone, please, confirm the above-described issue?


  Keep phone awake when audio is playing
Posted by: 3x5co - 12-27-2020, 05:42 PM - Forum: Mobian on PinePhone - Replies (2)

I want my phone to auto suspend, but not if music is playing. My player, gmusicbrowser, has an option to prevent a screensaver when the player is playing and fullscreen. However, it doesn't work on the Mobian Pinephone.

There's a program called caffeine that is supposed to let you tweak your sleep settings, but I can't install it on Mobian. I get these errors:

```
md5sum: /usr/lib/crust/scp.bin: No such file or directory
E: Sub-process if grep -qE '(u-boot-sunxi|arm-trusted-firmware)'; then touch /tmp/upgrade-uboot; else md5sum /usr/lib/crust/scp.bin > /tmp/crust.md5; fi returned an error code (1)
E: Failure running script if grep -qE '(u-boot-sunxi|arm-trusted-firmware)'; then touch /tmp/upgrade-uboot; else md5sum /usr/lib/crust/scp.bin > /tmp/crust.md5; fi

```

Any ideas?
