Strange behaviour after Mageia 9 upgrade

[hosadeeb]

Hi dear Mageia,
I've just upgraded from Mageia 8. After the upgrade I noticed a few strange things that could have already been reported by others, things I weren't able to correct myself.

• Now the screen never sleeps; not even after adjusting the Power Manager of XFCE, or XScreenSaver for that matter.
• Trying to launch gnome-control-center from the prompt does absolutely nothing. No error messages, either.
• My online accounts on Google keep asking to log in, despite having received a notification to that effect. Plus there's no way I can connect to my Google Drive, not even from the prompt.
• Nautilus, too, wouldn't work if launched from the Terminal within XFCE, with some error messages about a missing Python module (which is indeed installed) and lost connections with drives... But it seems to be working from Gnome Flashback, though I couldn't spot the Search lens...

Anyway, thanks a lot for bearing with me. I'm absolutely sure your more than marvellous efforts will remedy all this.

Did you create a new test user to rule out a broken user profile?

[hosadeeb]

I never thought of that. But there's nothing else that would suggest something is broken in my user profile.

Trying to launch gnome-control-center from the prompt does absolutely nothing. No error messages, either.

This appears to be how "gnome-control-center" currently behaves. it needs to be run from within Gnome

Note: if you are running a 32bit system, beware of "gnome-control-center mouse" as it will seg-fault and core dump.
a change is then written which will also then prevent any "gnome-control-center ***" operands from functioning. this is a reported upstream bug.

you would then need to change a setting in dconf-editor.

I've been using 64 bit for many years now. So, no problems from this aspect.

The reason I needed to access gnome-control-centre from XFCE (my main Desktop Environment currently) is that I needed to re-activate my Google Drive account, and I couldn't a way to do that from XFCE. And that's when I realised that activating the Google account is go-no-go vicious circle.

I also discovered the XScreenSaver issues these two error messages:

libEGL warning: failed to get driver name for fd -1

libEGL warning: MESA-LOADER: failed to retrieve device information
