Description of problem: Sunday 09/30/2018 This is a recurring problem. Over the past couple of weeks or so it seems to happen within a couple of hours of a reboot. When it does occur, it jumps to the login screen. So I have executed the login process and my setup process and then continued with my work. I should say at this point that I am using the version of Fedora Core, FC-28, that I installed two or three months ago as I remember. Some of the time, I was using LibreOffice Write to write and edit documents. At other times I was doing other normal such as simple browsing and research using Firefox, and I believe on one occasion I was reading my email which I use Thunderbird as my email client. On none of the occasions of a fault to login was I doing anything that required major resources such as building a large amount of source code to create a heavy application. In the past few months most of my development work has been writing Python 2.7 code for various applications. Almost all were text based, not GUI based with a graphical interface. Although I am doing study now, I am not an expert at building kernel code or other GNU code for system applications and tools. Given that, I can't provide much deeper information at this time. A suspician that I had when this problem began occurring was the fact that I was using two monitors, both ViewSonic 21.5". The primary monitor is plugged into the HDMI port of a simple 3 port video card (not a game card - it just has fins, not a fan). The second monitor was plugged into the VGA port. The third port, a DVI, was not used. When the failures became fairly frequent I suspected the second monitor plugged into the VGA port was causing the problem, possibly overloading the card. Although this setup had been working for some time before the failures began. I disconnected this second monitor, but the failures continued. I then dug out an older retired disk with FC-25 I believe. This also failed. So that lead me to think the video card was bad. I had another identical card so I switched. This one failed as well. So now I am stuck. I hope this information is useful. I also hope it isn't too much.

This message is a reminder that Fedora 28 is nearing its end of life. On 2019-May-28 Fedora will stop maintaining and issuing updates for Fedora 28. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '28'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 28 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
Fedora 28 changed to end-of-life (EOL) status on 2019-05-28. Fedora 28 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed.
