Sorry, my mistake. Recent kernel changes may be the trigger of this problem but would not be the root cause. If there is any process blocking waiting for entropy then that's the real issue. Because they are blocking waiting indefinitely for something that might theoretically take forever. And that's bad software design.
I guess therefore we don't need to find out which kernel version made it worse recently. We need to find out which process is actually blocking waiting for entropy. If anyone can figure that out from the logs, or by looking at open files of each process and seeing who has /dev/random open then it would help a lot. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1779476 Title: Ubuntu 18.04: gdm3 does not switch to graphics after update Status in gdm3 package in Ubuntu: Incomplete Status in linux package in Ubuntu: Incomplete Bug description: After update of gdm and kernel gdm3 no longer enables graphics. What happens: ============= With and without: WaylandEnable=false in /etc/gdm3/custom.conf gdm3 does not switch to graphics. In both cases I case the X process running (Xwayland or Xorg) but no vt has it. lightdm does work, but barely. It takes up to a minute to get to the login screen. What I expected to happen: ========================== gdm3 switching to graphics in ~20 after boot like pre-update.
