17.10 Problems brainstorm

[Wunsz]

Hello again,
after testing some combination I ended up with USB mouse & keyboard + DELL display connected via dock and Samsung via HDMI. The tell displays goes blank from time to time but does not disconnect (display manager thinks the display is still there, I can even move windows from that display).

On error, dmseg says:

Funny thing is, it seems to be totally random. Yesterday it happened only once. Today it already happened 4 times...

One more thing I noticed today is that sometimes dmesg spits out a bunch of these:

[pią lis 17 08:53:20 2017 <    0,009739>] pcieport 0000:00:1d.0: AER: Corrected error received: id=00e8

Which seems to be an error with my SSD disk:

Sometimes I belive I could write a blog about my hardware issues xD
