Bug Description

kernel(64bits) 4.15.0.42 causes a slowdown of the PC, reduces the size of the display, and a blocking if I try to run "NVIDIA X Server Settings". If I chose the kernel 4.15.0.39 at startup the operation of ubuntu is normal.

This bug is missing log files that will aid in diagnosing the problem. While running an Ubuntu kernel (not a mainline or third-party kernel) please enter the following command in a terminal window:

apport-collect 1806852

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.
