xserver does not work with kernel 4.13.0-32

[Harald]

Hi,

on one of my desktop computers (pls see file System.html) the xserver does not start anymore with kernel version 4.13.0-32. After logon, the KUbuntu splash appears, the HDD works some seconds, than the drive stops an the computer does not react anymore at all.

Just a SSH connection is possible, but a reboot or shutdown command results only in "connection closed". The computer does not react on these commands.

The computer has to be switched off be hard power off, reset or magic code REISUB. Using the xorg graphics driver instead the recommended nvidia driver does not fix the issue.

But, the "problem computer" works fine with the old kernel version 4.13.0-25 as well as older kernel versions.

However, two other computers, both with other CPUs and motherboards, (one of them has the same graphics card and driver), works well with kernel 4.13.0-32.

Thank you for help
Harald

Hi Joseph,
I have installed kernel 4.16.0-041600rc2_4.16.0-041600rc2.201802190311 and - it works!!!
I booted about 30 times, the xserver always runs and everything was fine.

So it looks like the issue will be solved with kernel 4.16.

I hope the daily build of "Bionic Beaver" will received that kernel soon.

Thank you for help
Harald
