KR260 Desktop Issue

Hello,

I’m trying to use Pynq on KR260 board as follow:

  • Prepare SD card with ubuntu - No issue
  • Boot and update ubuntu (apt update/upgrade) - No issue
  • Pynq installation - No issue

The trouble comes after rebooting the board. I don’t have Gnome Desktop anymore.

ctrl+alt + F8 doesn’t work. And I got simple error message " Cannot open default display"

Same issue on 2 board with the same process (according to the getting starting guide should work…)

Any tips to solve this issue ?

Cheers,

Hi @Nini,

Welcome to the PYNQ community.

We have not verified the Ubuntu image with Gnome Desktop after installing pynq, so. I would say this is something that is not supported.

Can you elaborate why you need to use Gnome Desktop and pynq?

Hi @marioruiz and thanks for repplying :slight_smile:

As the Starter guide is based on GNOME Desktop it would seem normal to be able to use the desktop :stuck_out_tongue:

Jokes aside, we have some tools based on Pyqt5 GUI and we would like to be able to run both in the same time :slight_smile:

Can you please provide the link to this getting started guide for my reference?

Did you try to reinstall gnome? Or what is the output of sudo systemctl get-default
Perhaps, this got changed when pynq was installed

sudo systemctl get-default reply : graphical.target

Yes I have tried to reinstall but same issue.

Unfortunately, I do not have a good answer.

Can you please open an issue in the GitHub repository? Issues · Xilinx/Kria-PYNQ · GitHub
Please include what you have tried, I think it may be easier to track this on GitHub

Hi @Nini,

I believe that this was just fixed in the latest PR on Kria-Pynq. Removing unnecessary purge that was blowing away the gnome-desktop (#36) · Xilinx/Kria-PYNQ@0053588 · GitHub

Hopefully it will do the trick. If you’re able to check to see if this solves your issue please do report back :slight_smile:

All the best,
Shane
