Created attachment 973210 [details] Xorg crash After upgrading to F21, X11 is crashing frequently using nouveau. I will attach a couple of Xorg.0.log files demonstrating the crashes.
Created attachment 973211 [details] Xorg crash
This crash typically happens while I am away from the computer so perhaps it's screensaver related. As you can see in the logs, I have dual monitors attached to this computer. Since I simply cannot have to re-login and re-establish my environment every time I step away from my computer I am going to have to either fall back to F20 or install the nvidia binary driver, which has always proven stable -- even if it is a pain in the ass to have to use.
This sounds the same as my bug #1205985. Can you check your /var/log/messages (or systemd journal) to see if you get similar error messages?
I'm using an Intel Graphics GPU now.
This message is a reminder that Fedora 21 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 21. It is Fedora's policy to close all bug reports from releases that are no longer maintained.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 '21'. 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 21 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 21 changed to end-of-life (EOL) status on 2015-12-01. Fedora 21 is no longer maintained, which means that it will not receive any further security or bug fix updates.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.
