Bug ID: 369450
Summary: Multiple monitor desktops & backgrounds are simply
blank.
Product: Planet KDE
Version: unspecified
Platform: Neon Packages
OS: Linux
Status: UNCONFIRMED
Severity: major
Priority: NOR
Component: general
Assignee: ranveeraggar...@gmail.com
Reporter: timber...@gmail.com
I'm sure this is likely a duplicate and someone else running 3 monitors has
reported it, but search did not work for me. I run Neon-user with the latest
updates as of today, and any monitors that are are on the VGA displays simply
appear blank. They do not get desktop backgrounds, there is nothing that
appears when I left or right click on them and nothing happens. This is NOT a
fatal error. If I send an application to a second or third display -- the
application goes there and appears, and it has no issues with multiple desktops
working as far as displaying the applications, but those displays any without
an application also appears blank -- whether its cube or any other type of
switching. Hardware is a core i5 2800, HD6870 on the open source driver as AMD
hasn't released a new one - one main monitor on DVI, secondary monitors on VGA
to DVI adapter and display port to VGA adapter. They are real actual CRTs if
its makes any difference for the secondary displays. I haven't tested this with
multiple DVI displays or DVI+HDMI.
Reproducible: Always
Steps to Reproduce:
1.Plug in VGA monitor as secondary display. (that one is blank with only 2)
2. Plus in VGA monitor as third display. (with 3 -- second two are blank)
3. Boot into actual session (no VM).
Actual Results:
Boom, same bug. Applications can be displayed on them, but backgrounds and
other functions (such as widgets) cannot be moved to them. The monitors do show
up under system settings, and otherwise function as intended. Maybe this is QT
bug upstream? Kwin?
Expected Results:
Expected similar behavior to plasma 5.6.5 where all displays show. Display bugs
like this should be a priority as they make an extremely bad impression on the
end user and may terminate someone doing any further testing if they think Neon
can't see their displays.
