No Display, Sound and Network stops working #23

Closed dumim closed 4 years ago

dumim commented 4 years ago

Hi,

Firstly, I want to say that I really appreciate this project. Cheers to the developer! Secondly, I want to point out that there really isn't clear instructions on how to install and use the driver (the section How to use in the README is not helpful) for someone who isn't knowledge about drivers, like myself. If that information could be extended that will be appreciated. Thirdly, I tried installing the drivers but the display is not picked up in the display settings and the screen is blank. However, now I have two new options in the Sound settings - usb extscreen Digital and Analogue. Also, my network breaks and the internet is not accessible (I presume it thinks of it as an ethernet connection perhaps?)

I am using Ubuntu 20.04. To install I used these steps:

  1. make all
  2. sudo ./startup.sh in the scripts folder. This did not work - after some digging, I changed the tcpdump line to tcpdump -Z root -i usbmon2 -nn -w /tmp/usb.pcap -c 20000 & and moved the file to the main folder. Following this, it worked and have the response : listening on usbmon2, link-type USB_LINUX_MMAPPED (USB with padded Linux header), capture size 262144 bytes . But the problems I stated above still remains.

Any help would be really appreciated. Thanks

@klogg Hi! Is this repo still being monitored? Would mean a lot if you could have a look at the issue mentioned above. Also, is there a donation page for this project, because I would love to show my support for this!

@DumiM JFYI - right now I am performing most of testing in a virtualized environment - passing whole USB controller as a PCI device into a qemu VM (using vfio) and while there are known "remove" issues (#12 and #22) I am concentrating on "happy paths" for small (480x800) and big (1920x1080) displays due to differences in memory allocation for them. Right now I have 2 issue left, both are on larger device: a) console does not start (something with fbdev emulation) and b) when playing kmscube some frames are getting lost. I hope to fix them soon and then I'll switch to testing in non-virt environment (Ubuntu 20.04 with XFCE).

It would be helpful if you can describe your system:

Thanks Please rebuild the driver with latest changes, and try to reproduce the issue. After trying to run the driver please give me output of dmesg command in console
