I have Ctrl+Alt+Super+Arrow (down/up) mapped to move window to next/previous workspace in Gnome Shell on Ubuntu 18.04 and until yesterday everything worked fine, but now the shortcut doesn't work any more. I checked in dconf, and the shortcut it is still there.
Every key still works on its own.
I tried to assign the shortcut to something else, but the Settings center doesn't intercept the shortcut when I try to click it.
I have a fresh installation of Ubuntu 18.04, I installed Slack but it doesn't show any icon in the tray indicator:

Every time I turn on the PC the nextcloud client complains that it doesn't know how to login to my server, because it says there is no keychain available.
How do I automatically unlock the keychain so it can work?

I have Ubuntu 16.04.1 fully updated.
Sometimes when in Webstorm the autocomplete popup is shown the monitor that has WebStorm flickers for a couple of seconds every time I press a key on the keyboard, making impossible to digit something. I have to change application and wait some minutes before I can use Webstorm again.
I haven't seen the problem with other programs

I've installed from scratch Ubuntu on a Dell XPS 13 9343. I remember there were some Dell repos in the preinstalled system, but I'm not able to find them anywhere online.
Do you know which are they? Is something useful in there (some hardware specific driver)?

I have a Nexus 4 for testing purpose only. Today I decided to do a full wipe and install last image, so I did (I removed some uninteresting lines):

When it reboot it is stuck on the screen with the text "Google". After ten minutes I tried to reflash it, but it said:
rpadovani@artemis:~$ phablet-flash ubuntu-system --channel devel --no-backup
error: device not found

So I restore default Android version, but I have the same error when I try to reflash Ubuntu.
What can I do?
I'm trying to upgrade a DB in an app. I use QtQuick.LocalStorage 2.0.
When I call db.changeVersion it works, but db.version doesn't change until app restarts.
db.changeVersion(db.version, "2", function(tx){...}); // Update database to version 2
console.log(db.version); //Should return "2", instead returns previous version of database
How can have the new db.version without restart the app?
