Hi all,
I have the Vivid Unit with GPSDR. The SBC and GPSDR were working fine, with a smoothly scrolling waterfall, proper GPU acceleration, etc. It recently started lagging (slow mouse response, apps taking too long to load, etc.). So I reinstalled the latest image (vivid-unit-v13-debian11-20240129.img), installed the gpsdrpp package, and enabled GPU acceleration according to the instructions at https://www.uugear.com/product/vu-gpsdr/#software. None of the steps threw any errors that I could see.
Now, the "About XFCE" dialog shows "softpipe (3.7 GiB)" as the GPU and not “Mali T860”. I have redone the complete software install and GPU acceleration process twice, and this behaviour continues.
Apps are very slow to load and respond, although the mouse is no longer laggy. The "GPU" icon in gpsdrpp doesn't light up, and the app is very slow.
I am using a RPi 5 power supply.
Has anyone else experienced this before? Is there any more information I can provide to help with diagnosis?
Thanks in advance!
I forgot to add that I am using the Extender 2, and that this issue is the same if I power the Vivid directly or through the extender. I also tried doing the install steps powering the device both ways.
Is it possible that when I put the unit back together after restoring using the FactoryTool v1.81 and maskrom button process, I borked a setting somewhere?
@davemcallister this has nothing to do with the power supply or extender, it is a software problem: the GPU driver stack is not well configured.
I would suggest to run:
curl -sL https://github.com/uugear/vu_install/raw/main/enable_gpu.sh | bash | tee install.log
After the installation, you have the install.log file to check. You can also post the log file here.
@uugear, that worked perfectly. Thank you!
