Backtrace of gnome-shell before crash
I use Fedora Rawhide since November.
And sometimes Gnome-Shell crashed, especially when I used Alt+Tab command.
The system is up to date, my graphical card is a nVidia Quadro 1000m powered by nouveau driver.
I have backtraces, all of it mentioned __memcpy_sse2_unaligned_erms as last function.
systemd-coredump generates core dump for gnome-shell, but I can't find this file. Before, with ABRT I can do it.
This bug appears to have been reported against 'rawhide' during the Fedora 26 development cycle.
Changing version to '26'.
I also have problems when using nouveau and wayland in a fresh fedora 26
workstation (x86_64) install (from the released live workstation iso). The gdm login screen comes up, but as soon as I try to login I get a mostly green wavy pointillist pattern filling the screen and the system appears to be frozen - won't respond to any keypresses, won't move the mouse pointer. My graphics card is:
01:00.0 VGA compatible controller: NVIDIA Corporation GM206 [GeForce GTX 960] (rev a1)
When I hit the reset switch to get the system to reboot and switch my login session to "Gnome on xorg" it logs in fine and the graphics seem to function perfectly.
Possibly relevant rpms I'm running (I have done one dnf update since the install):
I can confirm the same exact problem with Tom Horsley with graphics card: NVIDIA Corporation GK104 [GeForce GTX 760] (rev a1)
I have the same behavior as Tom Horsley as well, except even trying to start Gnome on X fails. Just a simple startx will lock the machine.
02:00.0 VGA compatible controller: NVIDIA Corporation NV41 [GeForce 6800] (rev a2)
all updates current
Confirming same behavior as Tom Horsley:
01:00.0 VGA compatible controller: NVIDIA Corporation GK110 [GeForce GTX 780] (rev a1)
Attempting to log in via Gnome /w Wayland locks the system and requires a reset.
Logging in with Gnome w/ Xorg works fine.
This message is a reminder that Fedora 26 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 26. 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bug reports from releases that are no longer maintained.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'
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 26 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 26 changed to end-of-life (EOL) status on 2018-05-29. Fedora 26
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
Thank you for reporting this bug and we are sorry it could not be fixed.
