Re: [opensuse-factory] Tumbleweed snapshot 20170112 - hanging Plasma, broken extended display
I managed to fix my issue as follows:

1. I disabled kscreen so I can manage the monitor setup manually with xrandr.
2. I enabled the second GPU with

xrandr --setprovideroutputsource 1 0

3. Fixed my layout with

xrandr --output VGA-0 --primary --mode 1920x1080 --pos 1280x0 --rotate
normal --output DVI-1-1 --off --output HDMI-1-1 --off --output VGA-1-1
--mode 1280x1024 --pos 0x0 --rotate normal --output HDMI-0 --mode
1280x1024 --pos 3200x0 --rotate normal --output DVI-0 --off

4. Added a script on pre KDE startup to perform the above both commands.

Although it works, the secondary GPU should be enabled (if it has a
monitor connected) by default and not need to be forced. I have
updated also the upstream bug because it is not the expected behavior.

Did a little more research...

My secondary GPU is detected (as it seems from Xorg.0.log) and the output of

xrandr --listproviders
Providers: number : 2
Provider 0: id: 0x9a cap: 0xf, Source Output, Sink Output, Source
Offload, Sink Offload crtcs: 2 outputs: 3 associated providers: 0
name:OLAND @ pci:0000:01:00.0

Offload, Sink Offload crtcs: 2 outputs: 3 associated providers: 0

but I cannot enable it. It is not listed (even disabled) on kscreen or
arandr. I tried to remove everything from /etc/X11/xorg.conf.d/ to
force autodetection without any luck.

I opened a bug here:
https://bugs.freedesktop.org/show_bug.cgi?id=99427 in case it is an
upstream issue but any advice would be helpful in case this is has to
do with any configuration, although before the upgrade to X 1.19 all 3
monitors were working as expected. The third monitor is waking up
during boot but stops working as soon as X comes up and doesn't work
after login also.

1. Plasma desktop does sometimes hang during startup, I see the
message "Yakuake started" at the beginning, but no widget, just the
empty background. In this situation, when trying to reboot, the
shutdown hangs on a task I haven't still identified for about one and
a half minute, systemd shuts it down probably forcibly after this
time.

For me, on my main desktop computer (Intel SandyBridge graphics), which has
a secondary display, plasma doesn't come up fully at all, the startup screen
(on the primary display) frezees and never goes away, while on the secondary
screen, things seems kinda usable but I don't have any widgets or anything
there.
As I still use KDM there, I could select a "Plasma Workspace (failsafe
session)" at login, which seems to turn off some gfx freatures ("hardware
accelaration" or anything else?) and that seems to work fine for now.
So I suspect the X update or something regarding Mesa is involved in this
issue.

On my laptop (IvyBridge), the plasma workspace comes up fine but the
plasmashell (task bar, desktop, etc.) freezes sometimes and gets unusable
but as I use SDDM already there I don't have failsafe mode available as a
selection unfortunately, so I can't try if that helps there as well.
