My Xorg.log.0

I run an up to date openSUSE Leap 42.3 on my T400s. All things worked very well
until some update about 1 month ago (04/18 ?).

2 Problems:

1) I use a docking station with an external monitor. Normally the lid is shut
but the T400s works anyways. Now when I shut the lid I get the clipboard
miniprogram added to the desktop automatically. Then mouse action s and keys
are accepted very slowing until the GUI doesn't react anymore. I'm guessing
that the close of the lid triggers the output of the clipboard buffers
endlessly, cause unknown. When I lift the cover problem goes away. I just have
to delete every miniprogram manually.

2) When I put the T400s in suspend mode every works as usual. But when I try to
wake it up again, I see a black screen with a mouse cursor, and the system is
frozen. No switch to text console possible, no shutdown or suspend, all mouse
and key events are ignored. I have to hard reset it every time.

Analysis:

In dmesg there is a message when I close the lid:
[   79.961099] i915 0000:00:02.0: BAR 6: [??? 0x00000000 flags 0x2] has bogus
alignment
[   79.961115] pci 0000:00:1e.0: PCI bridge to [bus 0e]

In Xorg.log.0 there is only an error with the IBM trackpoint which I suspect to
be unrelated.

The settings are:

I tried "uxa" AccelMethod too, no change.
I tried Kernel Versions 4.4.120-45-default instead of 4.4.126-default , no
change
I tried kernel boot cmdline parameter "i915.semaphores=1" , no change

I'm out of options now. My beloved T400s is almost unusable now due to the
updated software.
I'm in the process to switch to an T440s, but nevertheless I want to use it
sometimes in the future and perhaps others are affected too.
