What's Happening

When the system suspends and I try to resume, it's stuck at a black screen saying "device descriptor read/64, error -71"

What's the Likely Cause

It's happening with USB bus 1-7, which is my Goodix fingerprint reader, which libfprint doesn't have a driver for. I don't care about this device correctly functioning. I just want my system to resume.

What I want to achieve

To solve this, I basically want to do any of the 3 things:

1. Fix it so that the USB device no longer causes this error (unlikely)
2. Completely disable the bus so that the kernel doesn't even talk to the device (which causes the error)
3. Have GNOME shell or GDM ignores the error so that it resumes despite the error (which I don't care since the device won't work anyway)

Things I've Tried

Solution 1, as above

1. As suggested by this thread: https://ubuntuforums.org/showthread.php?t=797789, I configured usbcore.old_scheme_first to Y through /etc/default/grub. Now the kernel log prints two extra lines of:

usb 1-7: Device not responding to setup address.

without solving the problem.

2. I also tried setting usbcore.autosuspend to -1, but that changed nothing.

Solution 2

I tried disabling the device through udev rules. That, according to tutorials online, is just setting authorized to 0 on detecting the correct device. However, as I look into /sys/bus/usb/devices/1-7/authorized, the content is already 0 without me setting the udev rule. That is, the device should already be disabled, probably due to lack of appropriate driver.

Solution 3

Not sure where to look or what to try.

Some logs

$ lsusb
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 007: ID 27c6:5395 Shenzhen Goodix Technology Co.,Ltd. Fingerprint Reader

Bus 001 Device 009: ID 0c45:671d Microdia Integrated_Webcam_HD
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

I can confirm through the vendor and device ID that usb1-7 corresponds to the Goodix fingerprint reader.

Also, it seems to only happen on battery power, and yes, I'm on a Dell XPS 15 7950. But it's definitely different from Suspend fails to resume on Dell XPS 15 7590 on battery power only, because my case seems to be irrelevant to Bluetooth and I don't use deep sleep.

Thank you in advance and please let me know if I should post more detail!

I'm new to flatpak so I don't really know how exactly it works.

I tried to install python3 on my native system using apt and install pynvim with pip3 install --user --upgrade pynvim. (I did this when I was using snap and it's perfectly fine)

But still, my neovim cannot seem to have the provider working. This following is my health check result.

## Python 3 provider (optional)
  - INFO: Disabled (g:loaded_python3_provider=1).  This might be due to some previous error.
  - WARNING: No Python executable found that can `import neovim`. Using the first available executable for diagnostics.

EDIT1:

I made some progress on this. I found that the neovim flatpak app has host enabled so that I can access my native python3 executable through /var/run/host/usr/bin/python3. However, the path to everything that python3 depends on will need to be prepended with /var/run/host/, which is still not happening. Here is the new health check message.

Thank you!

I first installed Ubuntu then I wanted to try kde. So I did

sudo aptitude install --with-recommends kubuntu

or something similar.

When I decided I don't like it, I removed kubuntu and did autoremove.

I recently realized when I'm trying out i3 that everything in i3, terminal etc., are still in plasma style.

How could I 1. find and remove all remaining plasma packages or 2. let i3 use gnome packages rather than plasma ones.

Preferably the first option of course.

Thank you!
