Which image are you using, desktop or server? What's the content of /boot/firmware/config.txt?

I don't have problem with hirsute-budgie-preinstalled-desktop-arm64+raspi.img

And this bug should be fix only for ubuntu Hirsute Hippo

Older ubuntu versions don't have kernel with fixed vc4 v3d modules

The problem is due to LP: #1918110. A fix for that was released today so you should update and rerun flash-kernel (if it doesn't run automatically).

I don't understand your comment #4.

Are there any daily builds for raspbery pi ?

for my comment
I saw this:
Changed in linux-raspi (Ubuntu Groovy)
But It is should ubuntu Hirsute I think

Juerg Haefliger (juergh) wrote :

Ah yes, you're right, thanks. I removed Groovy and added instead Hirsute.

Daily hirsute images:

status: New → Fix Released
no longer affects: linux-raspi (Ubuntu Groovy)

Any reason why images from http://cdimage.ubuntu.com/daily-preinstalled/20210409/
don't have it fixed aleardy ???
and still I need to call flash-kernel to fix it?
