I know this question has been asked before in the last 5 years or so, but my situation seems to be different.
I recently aquired a new monitor for my laptop and I'd like to view a separate workspace on each monitor. I managed to have an extended workspace, but I had to replicate the panels and this seems to create a few problems, particularly with the clock and the notification area and I have a few other reasons to prefer separate workspaces instead of the extended workspace.A few informations about the setup:
Seeing previous questions, I have to add that I installed Bumblebee to reduce battery consumption and heat production and a change in this direction is acceptable only if it achieves the same results, i.e. switching off the graphics card for most of the time. There is a list of different drivers, in particular nvidia-346 is recommended, but I must admit I never dared to change it, because until now the current driver worked perfectly.
I couldn't find this question answered for my particular case (MATE+Bumblebee), only a few old questions (~2011) that say it's not possible. Did it became achievable? And if yes, how?
Thanks for the answer and for your time.
Edit: I also tried to upgrade the driver to nvidia-346, but nothing changed. I noticed nvidia-settings
is almost completely empty.
Easy. All you have to do is to run Displays in the MATE menu. Then choose expand desktop.
Then, according to this link, all you have to do is:
Right-click the panel you wish to move and select “Properties”.
Uncheck the “Expand” option under the “General” tab.
Grab one of the edges of the panel by clicking on the left or right end (top or bottom end for vertical panels)
Drag the bar to the desired screen and position
Check the “Expand” option in the “Panel Properties” window and click “Close”.
That would explain why It was hard to figure out how to move panels. I wasn't using the default theme.
Still getting those ghost panels though. However i have figured out when they start happening.
Seems that moving any blank panel works perfectly. However when moving panels with the default applet configuration on it things, they create ghost panels.
Haven't tested with alternative panel configurations to see if there is any specific applet that is causing it though.
Also here is a bit of clarification with what I'm calling ghost panels, and how they behave.
They basically seem to reference the panel that left it behind. So if i select move on a ghost panel it moves the original panel that created it.
Selecting remove panel on a ghost panel removes neither the ghost panel nor the original panel. However it does break the original panel. When the original panel gets broken like that it cannot be moved or removed, and copying the applets on it seems to crash everything.
Also another issue i came across when trying to track this down, removing a panel doesn't remove the applets from that panel. So whenever you add a new panel it recycles previous panel configurations. Also because of that applets will show as still on a panel, but they have an error status(in the applet settings menu).
All my previous posts are basically invalid :P
