    Hello!

    It seems that I have a similar problem after this disaster upgrade (when Qt 5.10 RC was upgraded to 5.10) . The sddm, though, works normally, but Plasma loads just until wallpaper and outline of the panel appearing, then everything disappears and falls to the black screen with mouse pointer (and then only Ctrl-Alt-Bsp twice saves the situation). The applications can be run from Konsole under IceWM (I tried Dolphin, Gwenview and Kate), but there is no icons in the toolbars. Running "plasmashell 2> plasmash.2" from Konsole under IceWM gives such output (continued in next message, the numerous QPainter::.. are skipped to fit the text into the message):

    It should be noted, that after the upgrade I got the message (white text on black screen), that I have to unlock the session from tty (probably the screen locker crashed after upgrade while I was in the another room). The system is Leap 42 with Qt, KF5, Applications and Extra update repos.

    I'm using Linux since 1997 and I had never seen such a disaster!
    At this point, I was thinking of switching to Plasma 5 LTS ... but probably, it is not a good idea.

    Default Re: Black screen after a huge update to Plasma 5.10 and libQt 5.9

    Similar issue here, symptoms not identical, Leap 42.2.

    I upgraded to the Qt 5.9/Plasma 5.10 packages last night (KDE Applications, KDE Extra, KDE Frameworks, and Qt5 repos), after which I had a lot of problems logging in -- in particular, my panel didn't pop up, window manager didn't work correctly, and other problems. Not all apps have problems; gwenview is fine, for example. It looks like it's the plasma stuff that has trouble.

    I didn't spot a message about Qt failure in my .xsession-errors-:0, but after bisecting my dotfiles, I determined that things work correctly if I don't use subpixel rendering. Enabling anti-aliasing is OK, and hinting style also doesn't cause any problem, but subpixel rendering causes a lot of Plasma components to fail. The fonts are, of course, rather ugly, but it's stable.

    I'm using X server 1.19.3 (from the X.org repo) and the stock libfreetype6 (2.6.3-1.2). Hardware, Dell Precision M6500 with Radeon HD 5870, using the free ati driver. In case it matters, I'm lying about my screen resolution on the X command line (stating that it's 72 DPI rather than 96, so I can get the fonts small enough for my preference), with a default font of Liberation Sans 10-point.

    It certainly looks like some kind of interaction between Qt 5.9 (or perhaps Plasma 5.10) and freetype2.

    Great shot Rick!
    You are absolutely right; subpixel-hinting causes the sddm crash!

    I have disabled subpixel-hinting and now Plasma5 starts (and works) properly.

    Finally, the guilty has been discovered!

    Good to know, but now you have to look at ugly fonts because of this screw up.

    A bit over a year ago this happened:

    I can confirm that disabeling subpixel hinting makes the update work, but this is not a solution. The fonts look horrible, so I am back to QT 5.7.x.

    In my case, sddm-greeter still crashes.
    I need to use another desktop manager, for example, kdm or lightdm; then I can launch Plasma 5 Workspace, bypassing sddm-greeter.
    In rare circumstances, I can see some graphic artifact in the fonts.

    So, this bug is not completely fixed yet.
