How do I clone the display?

[hallergard]

Has anybody managed to unify the displays using Plasma5 ?

[hallergard]

Have tried to understand what is happening. My starting point is a not unified display with my monitor DVI-0 as primary display and TV DVI-1 as secondary display. Going into System Settings/Display and Monitor - making sure the Monitor coordinates are 0,0 - and moving the TV to cover the Monitor - also making sure 0.0 coordinates. Pressing Unifiy display and then Apply updates the coordinates in ~/.local/share/kscreen/29a188dec574e6c7694496c85b854517 So far so good!

But when exiting settings/display one gets asked to confirm the changes - this updates ~/config/plasma-org.kde.plasma.desktop-appletsrc from a 10-page text file (including coordinates for desktop and panel Widgets and Icons ) to just over 1-page file (with just the panel Widgets and Icons). When logging out and in again the display on the Monitor and the PC are identical - showing the panel Icons and Widgets, but nothing on the desktop. Tried to copy back the previous 10-page file and relogin, but to no avail.

The above happens with the layout setting "Desktop" in the "thingy". Changing that to "Folder" and applying Unify settings and Apply as above, updates the coordinates in~/.local/share/kscreen/29a188dec574e6c7694496c85b854517. Fine! But one is not asked to confirm the changes when exiting settings/display, and thus the ~/config/plasma-org.kde.plasma.desktop-appletsrc is not changed. When logging out and in again the display on the Monitor and the PC are identical - showing the panel Icons and Widgets as before, but on the desktop there are no Widgets and the Icons are in ordered rows on the top of the desktop rather than i my previous arrangement. I can rearrange the existing Icons but cannot ad new Icons. When trying to add Widgets, they either disappear straight away, or if I manage to move them into the desktop, they cause crash.

I have other distros on the same PC, so I will keep 15.04 on its partition, until Plasma 5 is amended. http://tinyurl.com/btjth3j Prefer KDE rather than Gnome and Unity, so as Fedora 22 gives similar problems with Plasma 5, I am likely to mostly use Suse 13.2 for the time being.

If you're not wanting plasma 5, you can go to Kubuntu 14.04 and use Plasma 4 - no need to go to another distro...

[hallergard]

Sorry, but this was not the solution - not stable - not sure now if the layout should be wallpaper or folders. Think I will give up on trying to unify the display for now, and use other distros when I need to. Plasma 5 does not seem ready for it!

[hallergard]

Yes, the "thing" in the top left corner - changed wallpaper to folder - and after saving there were more settings to chose the wanted folder /home/myself/Desktop. And now it appears on both monitors. Thanks!

[hallergard]

Thanks! Edited so that both the Monitor and the TV has the same x=0 and y=0. Upon boot the display were unified, but no icons on the desktop. Maybe I am asking the wroing question??

It seems as when in Unified mode the desktop will not show the icons in the folder /home/myself/Desktop - is there a way to enable this?

Where are the display settings saved??

In ~/.local/share/kscreen.

Where are the display settings saved??

Created new user and logged in. Tried overlay, ok till I logged out and in again as the new user

[oshunluvr]

yes on the Xrandr - clipped on the copy-and-paste, lol.

A cli command like xrandr command is not saved, which is why it's a good way to test. If it works until you log out, I would suspect some settings issues elsewhere. Try creating a new user and logging in there and trying the overlay.

[hallergard]

Thanks oshunluvr think you mean xrandr - the above command wint xrandr does the same as putting one on top of the other or tapping unify screens - which is fine until I log out and in again: the desktop shortuts are not there anymore. Where is this configuration supposed to be saved?

What is the result of this command:

randr --output DVI-0 --mode 1920x1080 --output DVI-1 --mode 1920x1080 --same-as DVI-0

[hallergard]

Screen 0: minimum 320 x 200, current 6112 x 1152, maximum 8192 x 8192
DisplayPort-0 disconnected (normal left inverted right x axis y axis)
HDMI-0 disconnected (normal left inverted right x axis y axis)
DVI-0 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 476mm x 268mm

DVI-0 is the monitor using the VGA port of the video card and DVI-1 is the TV using the DVI-I port with a DVI-VGA-adapter and the HDMI port is not used at all.

I was using Unify Outputs because the kcm module is really finicky about dragging. I can position one display on top of the other (both at 0,0), but Applying makes one of them move slightly. I don't remember having this problem pre-Plasma 5.

If I set both displays on and Unify Outputs, then reboot, the laptop display is shut off as kde is starting up.

For now I'm just using two scripts, created with the help of arandr, to manually set both displays on or turn off the laptop display.
