is an instance of nautilus running? is it handling the destkop and icons?

[Rus F Adrian (tue-deactivatedaccount)]

yes, nautilus is running in the background, and is handling the desktops and the icons.

[Sebastien Bacher (seb128)]

seems similar to bug #724285, well if nautilus is running why do you say it fails to start?

I just experienced this on an up-to-date natty. After applying updates, I restarted and was informed nautilus was not responding. Upon reboot/login nautilus was not running/responding and launching from terminal resulted in

(nautilus:4110): Unique-DBus-WARNING **: Error while sending message: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.

It looked like a nautilus process was running/hung, but would not launch the gui, nor provide context menu on right-click of desktop.

Also...

sudo kill -9 4110

...appeared to do nothing. Never experienced that before!

[tekstr1der (tekstr1der)]

This continues to affect me. I can no longer run the nautilus file manager in a useable state. Whether launching from the command line or using the unity launcher for Home Folder, nautilus is hung, not responding and 100% CPU between all 4 cores is being used. I am able to view this behavior under gnome-system-monitor tab "resources", however the "processes" tab does not show what's eating CPU, nor does top, nor htop. Also, htop correlates the four cores totaling 100% constantly. When nautilus does "run" (show its gui), it grays-out during any actions (since the CPU is pegged, I'd assume).

I created an additional user account to test this. Nautilus appears to work correctly under a unity session with the new user.

Logging back in with my normal user results in this same behavior, even using the classic session w/o effects. Only by logging in to a safe-mode session does nautilus work properly and CPU usage is normal.

What could possibly have become corrupted suddenly? The .nautilus folder in ~/ is empty. I removed all gvfs-metadata. I cleared the zeitgeist cache and recently-used.

Killing the nautilus process immediately spawns another, so this is negatively affecting my entire experience w/natty since the CPU is constantly running at 100%

[tekstr1der (tekstr1der)]

Update: I found the culprit...even though there was no indication of what process was consuming all CPU cycles.

Disabling the ubuntuone-daemon from starting automatically allows everything to function correctly.

There's already a bug filed for this issue, bug # 776386.

Marked as duplicated then, thank you.
