I think my current problem is related to long standing "nouveau" problems with nVidia graphic cards: my "syslog" contains many entries of the form "nouveau :00:0d.0: bus: MMIO write of FAULT at 00b020" (of "..." varies and at "..." can end in "b000", "b010" instead of "b020"). Tryin

I just recognized that the freeze does not inhibit all reactions to the keyboard: "SysRq" keys are still recognized (at least this was the case in my last 3 graphical login freezes). I will try to find out whether I can clean the state via "SysRq" keys (maybe the "V" key). -- You received this b

Meanwhile, I have performed about half a dozen successful graphical logins with the 4.15.0.36 kernel. As a consequence, I do no longer believe that the observed problem has to do with the kernel upgrade to 4.15.0.36. Instead, I believe now that it is an intrinsic problem of the graphical login in U
