Ubuntu 24.04 LTS on RPI 5 8GB [SUPER SLOW]

[Alexander Higgins]

Hi All,

I recently got the message from Software Updater to upgrade to 24.04 LTS on my Raspberry Pi 5. Having done this now, the experience is awful. Something as simple as trying to open a terminal instance or even the file explorer takes in excess of 30 seconds!

My experience with the previous version 23.10 was incredible even for the Pi - everything was so snappy and fast I wouldn't have known I was using a Raspberry Pi to run it.

Has anyone come across this issue as well? I apologise if this is a known problem I've spent the better part of my evening trying to search the internet for an easy fix. I really don't want to have to do a fresh SD card wipe and reinstall back to 23.10 as I have already spent so much time setting up preferences etc.

Appreciate any help in advance!

Hi there,

I am affected by this bug and would like to offer using me as test user in case someone looks into it. Got a broad IT background but am new to the processes in Launchpad. Thanks for hints on how I can contribute to a solution without being an in-depth expert.

I had this happen from a fresh install of Ubuntu 24.04. No upgrade required, just a clean install. I too have a Pi 5 8GB version.

Applications seem to run decently once they're open, but everything takes forever to load and there doesn't seem to be any sort of disk activity in the meantime. Terminal is the worst offender, it often just won't open.

I've had this happen with USB and SD card boot across multiple cards and drives, and my case has extremely good thermals.

However, I *have* just found a possible correlation with the power supply. I have a 5A official power supply, but if I use the inline power switch with the *same* supply - which filters out some of the pins so the Pi thinks it's a 3A adapter - I have this problem. It appears to work much better when it detects that it really has 5A available. I only just discovered this and was really not expecting it, after all I'm booting from SD with no peripherals and no overclocking.

I guess I'll be not using my inline power switch (which is annoying since I switch my surge protector and the Pi still boots on power application) but hopefully this can be figured out soon.
