The same problem happens in 32 bit and 64 bit systems -- both installed before January 2019 and AFTER the problem was introduced (that is, complete new installations AFTER). I have an Acer Aspire R15 laptop. To reproduce the problem -- after the system boots: Ctrl-Alt-F1 (unity) or Ctrl-Alt-F3 (gdm3). For arguments sake, I'll only show unity. type in: cd /tmp ed a And that puts you into the "ed" editor in "append" (add) mode. Ctrl-Alt-F2 (or Alt-F2) and duplicate the typing in of F1 above Ctrl-Alt-F3 (or Alt-F3) and duplicate the typing in of F1 above Now, Ctrl-Alt-F1 (or Alt-F1) back to screen #1. It is at the system prompt rather than and "ed" prompt, and the error "stdin: Resource temporarily unavailable" is displayed. If you move to "Alt-F2" or "Alt-F3", you don't see the error message there, and those screens seem unaffected -- that is, it seems to affect only "Alt-F1". For some reason screen #1 aborts the program that is running when you move away from "Alt-F1". You can confirm that the program aborts when moving away from "Alt-F1" rather than moving back to "Alt-F1" by doing an "ssh" to that computer from another computer and doing a "ps -e | egrep tty1" before and after moving away from "Alt-F1". You can exit those "ed" sessions back to the system prompt by typing in: . q lsb_release -rd Description: Ubuntu 18.04.1 LTS Release: 18.04 version.log --> Ubuntu 4.15.0-45.48-generic 4.15.18 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1814604/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp

I tried to do the "apport-collect 1814604" above, but I never got an indication the browser was trying to connect to the https server. So, I am changing status to confirmed, as shown above. ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed -- 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/1814604 Title: Alt-F1 aborts program when moving away from screen Status in linux package in Ubuntu: Confirmed Bug description: This problem was introduced in the "4.15.0-44" or "4.15.0-45" kernel in late January 2019.
