Bug ID: 373836
Summary: Cannot use more than 1 screen
Product: plasmashell
Version: 5.8.4
Platform: Mint (Ubuntu based)
OS: Linux
Status: UNCONFIRMED
Severity: major
Priority: NOR
Component: Multi-screen support
Assignee: aleix...@kde.org
Reporter: unf...@gmail.com
CC: plasma-b...@kde.org
Target Milestone: 1.0
I'm using a laptop with external monitor.
I have internal laptop display - let's call it A.
I have an external monitor connected via VGA - let's call it B.
I had severe problems with using the external monitor with Plasma 5.6.4.
Now I upgraded to 5.8.4 and initially I thought my problems are gone - I
connected B - it was on, with it's own panel there.
I disconnected B - it was off, the B's panel was hidden, not falling back onto
A, covering it's panel. Great! I suspened and restored the machine - now the
problems are even worse. I reid rebooting - no luck. I am unable to use two
monitors at the same time now after the upgrade.
When I run the laptop with B unconnected, A is running fine.
As soon as I connect B, A goes off. Panel and windows from A move to B, and now
B is my only display.
When I disconnect B, A goes back on and the panel and windows go back to A.
In Plasma 5.6.4 I was able to finally get both A and B working by reconnecting
B several times and reopening the Display Configuration several times. Now it
doesn't help - I can never have both A and B on at the same time.
After connecting B I open the Display Configuration and I can see B enabled
there, and A disabled - I enable A and hit Apply. As a result B is on, but goes
all black and I only see the mouse cursor on it, while A is still off - not
just black, there's no backlight.
I'm recovering my system to a state before upgrade to be able to use both
screens again.
