Re: Ubuntu 20.04 HDMI display driver problem

If you haven't already, try adding the following to /boot/firmware/syscfg.txt (or usercfg.txt):

Code: Select all

dtoverlay=vc4-fkms-v3d
That loads the "fake" KMS framebuffer which is considerably better for desktop usage. There's a few more bits in this post in case they're useful.

Dave.

Dear Dave,

I have reported a bug as you suggested with the bug reference Bug #1876265

Hope this helps,

Excellent, thank you - that's going straight on the list of bugs I'm tracking this cycle. Will see what I can find out when the hardware arrives.

Install the pi-bluetooth package:

Code: Select all

$ sudo apt install pi-bluetooth
$ sudo reboot
There's some bits that run on startup - I can't remember if the reboot is absolutely required after installation so I've just included that as a precaution.

Re: Help to install Spotify in my RPI 4 with Ubuntu 20.04

First there is no linux version of Spotify on ARM. If I may ask, why are you trying to go to the latest which maybe isn't tested thoroughly on RPI. Why not stick to raspbian. It's tested about as thoroughly as we can manage (which, knowing a bit about what goes on behind the scenes here, is pretty ...

Re: Ubuntu 20.04 LTS screen too large to fit tv issue

If the display is falling off the edges then you want overscan enabled (in other words, the opposite of "disable_overscan=1"). For some reason our default framebuffer (the one without the FKMS overlay) seems to disable overscan implicitly (I suspect something to do with u-boot that I haven't had tim...

You probably need the FKMS overlay loaded. On the boot partition (normally mounted under /boot/firmware in Ubuntu), add the following line to syscfg.txt or usercfg.txt (doesn't matter which): dtoverlay=vc4-fkms-v3d Then reboot. With this overlay in place you *should* find that both displays appear (...

As noted, Core is aimed at IoT. To expand a bit on what that implies: think of Ubuntu Core as a deployment platform rather than a general purpose OS. It's the sort of thing you might use to support an appliance (some self-contained hardware device) that happens to have a Pi driving it. In other word...
