Created attachment 1074177 [details] journalctl -b -8 -n 800 | grep -v avahi xorg-x11-drv-nouveau-1.0.11-2.fc22.x86_64 plasma-workspace-5.4.0-6.fc22.1.x86_64 kernel-4.1.6-201.fc22.x86_64 When resuming system operation from sleep or standby, the system will operate normally for approximately 5 minutes before a complete system lockup occurs. alt-f2 will not bring up krunner in Plasma, and ctrl-alt-f(x) will not switch tty terminals. I have not been in a location yet that would allow me to attempt to ssh into the system, but I should be able to get information that way this evening. The only information I can get out of it so far is the attached journal output - it is the last 800 lines of the journal, minus 245 unrelated avahi entries.
Was able to ssh into the system this time after the lockup. This time, it only took 38 seconds for it to lock up. The mouse cursor is still visible and moves around the screen, but nothing is clickable, and no input is processed from the keyboard. I am attaching the full journal from when it resumed until it eventually rebooted - the log shows that the reboot instruction was not processed immediately, either. It took 00:02:31 for the system to finally shutdown - too many processes were hung.

This is still happening in F23. xorg-x11-drv-nouveau-1.0.12-0.3.fc23.x86_64 plasma-workspace-5.4.2-4.fc23.x86_64 Can someone please take this? I may be forced to either use the proprietary drivers or switch to a different DE. I like nouveau - when it works - and I think Plasma is the best DE out there. I don't want to switch either, but if I can't use my laptop as designed, then....

Ilia Mirkin over at freedesktop.org seems to have found the root of this problem. When can we get it pulled into Fedora? http://lists.freedesktop.org/archives/nouveau/2015-October/022732.html
NVidia GTX 750/Ti Video card with Fedora23 Workstation freezes after login. Knowing I have problems with this card I installed Workstation using the onboard VGA. That works good. Than I switched back via the BIOS to the NVidia Card in PCI. Using DVI-D-1. Starting workstation, I cannot come further than a first login: All three possibilities GNOME, GNOME in Wayland and GNOME classic, the system freezes after the first login. I work with a Lenovo Thinkstation E32 and monitor Thinkvision LT2252P (1680x1050) (using VGA or DVI-D) This problem does not occur with Fedora 23 Mate. Surprisingly Mate accepts the NVidia card. For workstation and mate the nouveau driver used is: XORG-X11-drv-nouveau- 1.0.12-0.3.FC23 X86_64, Linux kernel 4.2.6-300 FC23. Is there a solution for this problem?
You can try enabling SysRQ by adding the line `kernel.sysrq = 244` in /etc/sysctl.d/sysrq.conf (see documentation at [1]). If you can SAK (SysRQ key + k), you could kill all applications on the current tty. This way you can at least run a shell or relogin without killing (forced power off) linux.

This message is a reminder that Fedora 23 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 23. 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 '23'. 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 23 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 23 changed to end-of-life (EOL) status on 2016-12-20. Fedora 23 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.
