I don't think it's criminal, it simply won't work the same in every country.

The worst that could happen is "no connection", imho.

I had a similar problem/symptoms... desktop & nVidia graphics, after updating Daedalus (X11 packages) last week.

one screen went blank during boot and then did not revive.

I tried lots of things but was at a loss.

I'm using Plasma (KDE5) and I found one screen was disabled in the system settings, display&monitor.

First time this has happened. After a while, and quite a few reboots I realised the 2 screens were like stacked, but one was disabled.

So check that.

On box No.2, The blank screen could be that the system is trying to use non-X like "Wayland". (never got it to run on my setup)

And in my experience a blank white screen is normal for a fresh install sddm login page.

But If I move the mouse around the bottom left corner there is a choice (drop-down menu), though nearly invisible to change it to Plasma-X11 (a blank white screen).

Just last night (after reinstalling Chimaera like you did, just to check the hardware) did the full install & upgrade for Daedalus &
this morning it booted fine.

I hope this helps you.

I agree with Fred, you need to go into your bios setup and switch off secure boot, enabling/allowing legacy boot.

You may change it back later.

Welcome! :-)

I tried to install my way back to a reasonable media system...

I re-installed elogind and rebooted & everything is back...
I can use synaptic package manager (required a password dialog, at least)
I have sounds
I have all the restart and shutdown buttons (so I don't have to logout and ctrl+alt+del to restart)

I will try again next time I have a clean install.

...imho, it's just M$ hobbling the competition.

For what it's worth, Pre-empt is not RealTime, but close.

I hope it keeps working for you.

See how you go when playing back 14 tracks while recording overdubs in real time.

Minimal xruns.

To setup /etc/fstab from /dev/sd(x)(n) to UUID

Use lsblk blkid and fstab, for clues

you might need root access for one of those.

This will give you the uuids and show you which /dev/... to follow.

See how you go.

That is the same folder I saw after my last post.

But I wonder if it is a permission issue, ie read/write to folder or linking.

Hi, do you have a /home/(user)/Desktop folder in your file manager?

You might find the icon there.

Otherwise, you might search for the (program-name).desktop file for that program in the $USER directory.

On an experimental system... as an experiment.

Biggest hurdles was when glibc version changed between install and upgrade.

What was a big thing at the time was multimedia on desktops and laptops and the fragmented sound device specification(s).

The same code writer was involved.

From what I read... (quite a while ago, if my memory serves me well.) the code was not conforming to FOSS standards,

but seemed to work so well it was adopted (capitalist style).

That mess is pulse, followed up with systemd...

1st thing I noticed was, now all your text logs are in binary (1s and 0s)

Also was the introduction of more security measures

(EUFI, secure-boot, apparmor(maybe not this one, but pretty insiduous))

which seem to divide the community rather than unite us.

So, imho I think it's money.
