Welcome.

A bit more information about e.g. your hardware (and specific software/drivers) could help somebody to solve your problem…

I am trying to use Kubuntu, I have a double boot with LDME 6 on one side and Kubuntu on the other one . On the LDME 6 when the computer comeback from sleep no problem all come back normal on Kubuntu 24.04 after coming back from sleep I have a blank screen. Now to come I need to reboot and use advanced setting to me back to Kubuntu. I run check on the file system, run dpkg no luck

What do you have; Desktop PC or Laptop. Make and Model. If Desktop, what Make/Model of display?

[Schwarzer Kater]

Do you use an Nvidia GPU?
If yes: which model and which driver version do you use (and from where was the driver installed)?

My display is AMD Radeon Pro WX5100 and the motherboard is Asus Pro WS X570-ACE and never I have this problem with Debian, Fedora or Gentoo. I am just trying to see if Kubuntu is a reliable operative system for my next project. But up to know I am puzzle because I have tried so many operative without this can of issues. The system on this double boot the hard drive is Samsung 980 1T. The LDME 6 have is own NVME

If it is a commercial project I would wait until (K)Ubuntu 24.04.1 has been released and stick with Debian for the time being…
Or use Kubuntu 22.04.4 LTS or Kubuntu Focus in the meantime - see Overview: Kubuntu, its parent and some of its siblings.

Non this is not a commercial project I use different operative system to learn. I will have stay with Gentoo but is too different from Debian

Perhaps you should try first, if the current default Ubuntu 6.8.0-31-generic kernel for 24.04 solves your problem.
Which other core components of the system have you modified?

Are you running Kubuntu in a virtual machine? Otherwise "Graphics Processor: llvmpipe" is not correct and you have a GPU driver problem.
If you are: VMs can behave differently from real hardware and this could also be a cause for trouble - depending on the specific VM and the used virtual graphics support.
