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.
