Compiz/Nautilus Freeze on Icon Drag

[Dylan]

When compiz is enabled and files are being dragged to/from a nautilus window, the desktop will freeze if the nautilus window in list mode is horizontally scrollable. Steps to replicate on my system:

1) Enable compiz. Exact settings seem to be irrelevant. I disabled them all and the problem was still evident.
2) Open a nautilus window containing some icons.
3) Enable list mode.
4) Ensure there are enough columns of information such that horizontal scrolling of the window would be require to see them all.
5) Begin to drag an icon.
6) The desktop will *almost* freeze. Some small and intermittent mouse movement may occur. However, the only way to rectify the situation is via a force kill of X (e.g., alt - sys req - k).

Repeating the above steps except with step 4 having no horizontal scrolling will not entice the problem.

The system is Unbuntu 8.04 with all updates as of the date of this bug. Video card is nvidia. Default kernel (2.6.24-16-generic) and nvidia drivers (169.12). compiz-core 1:0.7.4-0ubuntu6. nautilus 1:2.22.2-0ubuntu4.

This problem is not related to the compiz "reflection" plug-in as reflection was disabled for both tests.

seems to be a compiz issue, a nautilus hang would not block other things than nautilus

[BrownieBoy (mike-brown-hotmail)]

I'm experiencing this one too, and under the exact same circumstances that you describe. My hardware and installation matches yours too.

I'd gone as far as attempting to swap out Nautilus for PCMan File Manager to try and rid myself of this, but now I know that it's List Mode only, I think I can work around it.

[David (dmlary)]

Same problem occurs for me. Default ubuntu install with nvidia drivers running compiz. Attempt to drag a file in nautilus, and the system will become nearly non-responsive.

Replacing compiz with metacity by running "metacity --replace" allows drag and drop to work just fine.

[David (dmlary)]

This looks like it may be an nvidia driver problem. I repeatedly caused the system to hang by dragging files which resulted in a number of messages from the nvidia driver showing up in dmesg (complete dmesg attached).

The system was a default Gutsy install on a Thinkpad T61, no additional plugins enabled in compiz.

[BrownieBoy (mike-brown-hotmail)]

Problems now gone for me. Got some updates from the repositories this morning, so I'm guessing that may have fixed it.

Can anybody else confirm/deny?

[Dylan (dreilly)]

The problem is still evident for me (the bug originator). However, the behaviour has changed slightly after recent updates to the kernel, nvidia driver (169.12+2.6.24.12-17.35), and nautilus (1:2.22.2-0ubuntu5) - although I know not which package caused the change. The original problem is still 100% reproducible except that now the X session crashes after being near deadlocked for ~ 5 seconds. Before the near deadlock would continue indefinitely.

FYI, I am using the "pink shadow" fix (as described here: http://tombuntu.com/index.php/2008/04/28/workaround-for-pink-shadows-with-compiz/), but the bug still occurs with and without it. I only mention this b/c is is a change to the default install of the nvidia drivers.

[BrownieBoy (mike-brown-hotmail)]

My Nvidia driver is still at 169.12+2.6.24.12-17.34, which is the one from the repositories (for me, anyway). Same version of Nautilus though.

[burton82 (bburton82)]

i can confirm the bug.
Same here with a fresh install of ubuntu hardy on a amd64 system.

[burton82 (bburton82)]

i think the bug should be become a higher priority because the crash can cause data loss (not able to shutdown programms and documents).

[Cyp (cyprien-pouzenc)]

Same bug with Nvidia GeForce 8400M G and nvidia-glx-new drivers under Hardy.

[Augusto (augusto.rendon)]

Same here with nvidia quadro NVS 140 and hardy amd64 system.

[Dyqik (paulkgrimes)]

Confirmed here with nvidia quadro NVS 140 on hardy amd64 in a Thinkpad T61, using current hardy kernel and drivers (as of 30th May 2008). The freeze is also causing display corruption in the destination nautilus window here, and maxs out the CPU load.

I can unlock the freeze by switching to a console and back to x with ctrl+alt+F1 and ctrl+alt+F7, although the first switch takes some time to happen.

I don't see the dmesg output reported above. I instead see

[7021.918090] NVRM: Xid (0001:00): 13, 0001 00000000 00005039 00000328 00000000 000000023

[Dyqik (paulkgrimes)]

To add to my report above, I also see the wireless network drop at the same time as the NVRM error occurs. I'm using the iwl3945 driver. The wireless networking reconnects once the freeze unlocks.

Something very similar to this appears to be reported in http://intellinuxwireless.org/bugzilla/show_bug.cgi?id=1476

I'm experiencing the same bug, with one difference: the xserver restarts alone after freeze.

[BrownieBoy (mike-brown-hotmail)]

Problem returned for me today, for the first time in several months.

The last change that I'd made to my system was to change the Desktop Theme. So, I set the Desktop Theme to what it was previously, and the problem went away again. The theme that causes the problem for me is Clearlooks. With any other theme I've tried - whether downloaded from GnomeLook or one of the standard themes - it's fine. Only on Clearlooks can I reproduce this bug.

Can anybody else confirrm/deny this?

[Dennis Schwertel (tmassassin)]

Same problem occurs for me.

[Dusan Maliarik (dusan-maliarik)]

+1 for this, I'am using nautilus just because of drag'n'drop, in this state it is unusable for me

[BrownieBoy (mike-brown-hotmail)]

@Kinkerl and Dusan,

Yes, but is the problem connected to the Clearlooks theme for you, or does it happen no matter what the theme is set to? Your answers were not clear on this point.

[Cyp (cyprien-pouzenc)]

After having reported the same bug here, I stopped to use the drag and drop, just copy and paste, to avoid any risk of freeze. After several official, proposed, and backports updates, I try to reproduce the bug... and I do not. Everything works correctly, while I have not changed my graphic theme, using Clearlooks.

There is a duplicate error here: https://bugs.launchpad.net/ubuntu/+source/nautilus/+bug/223164

[Dennis Schwertel (tmassassin)]

@BrownieBoy
i use a black theme called: gnommapiumalooks (i think it is related to clearlooks). i can confirm that this problem is related to the theme.

[Tom D. (dickmant)]

I can confirm that this issue is also occurring for me. I will start to drag a file, and my cursor will continue moving while the icon seems to almost get stuck. If I continue to hold the mouse, and wait a second, it seems to "get over" this issue, and continue moving.

[Robert Ancell (robert-ancell)]

Thank you for taking the time to report this bug and helping to make Ubuntu better. You reported this bug a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue for you. Can you try with the latest Ubuntu release? Thanks in advance.

[Dennis Schwertel (tmassassin)]

not an issue anymore

[RonzO (ronz0o)]

Thanks for the reply Robert, but I don't think this is a problem any more. I haven't had this happen in a while, so I'm assuming it is not a problem any more. Feel free to change the status of it. =)

[Travis Watkins (amaranth)]

Thanks for the update, closing bug as fixed. It sounds like it was actually an nvidia problem though...
