xscreensaver-getimage can't find image on samba share

I am also having this problem on two machines. One is a laptop with an s3 unichrome adapter, one is a desktop machine with an Nvidia 8400GS. I don't think the gfx card is the problem, but something with the open() call that xscreensaver-getimage is doing. I can list the directories from the shell and thunar just fine.

Something is getting a filename to xscreensaver-getimage to send to the screensaver renderer:
xscreensaver-getimage: file does not exist: "/media/evectra/evectra/Media/Pictures/2008/East Coast Trip, May/Boston Freedom Trail/IMG_1680.JPG"

The laptop exhibited this behavior in Ubuntu 9.10. so I upgraded it to 10.04, same problem.
The desktop is at 10.10

The files are coming from a remotely mounted windows share hosted on a Windows Vista SP2 machine.

I did do a workaround once that involved setting up a VM, mounting the windows share on the VM, then NFS mounting the VM directory on the glslideshow machines, but that is a bit ridiculous.

What other details can I provide that would be useful?

Status changed to 'Confirmed' because the bug affects multiple users.

Can you please run:
 xscreensaver-getimage -verbose -directory /media/your-mounted-network-share-picture-path root

here's the result of running "xscreensaver-getimage -verbose -directory /media/your-mounted-network-share-picture-path root":

xscreensaver-getimage: grabVideoFrames: False

I am not able to reproduce this on a samba mount using the normal gvfs mounting in Gnome. What is your "automount" about? What does "mount" say about it?

Which version of xscreensaver are you currently using? On which distro version?

I'm having the same problem
xscreensaver latest version
Ubuntu 11.10 (clean install) w/ Unity running

mounting a windows share with:
mount -t cifs //10.200.10.187/shared$ -o rw,bg,vers=3,proto=tcp,hard,intr,rsize=32768,wsize=32768,forcedirectio,llock,username=root,password=xxxxxxx /mnt/shared/

I can access this share and the images in it using other applications like gimp and firefox.

I have another machine with different hardware running Ubuntu 11.10 (upgraded from 11.04) but running lubuntu desktop instead of unity and this works ok.

in the error it says the directory doesn't exist. during a preview, the error lists the actual names of the files it is reading from the directory but then says the file doesn't exist.

I ran the xscreensaver-getimage command:

the file exists:
root@T420s:~# ls -la /mnt/shared/pics/yWPk9.jpg
-rwxr-xr-x 1 root root 47484 2011-05-26 14:36 /mnt/shared/pics/yWPk9.jpg

xscreensaver-getimage sees the dir:
root@T420s:~# xscreensaver-getimage -verbose -directory /mnt/shared/pics/ root
xscreensaver-getimage: grabDesktopImages: True
xscreensaver-getimage: grabVideoFrames: False

xscreensaver-getimage: grabbed 24 bit screen image to real root window.
xscreensaver-getimage: displaying 1920x1980 image at 0,0 in 1920x1980.

but it doesn't see the file:

xscreensaver-getimage: file "/mnt/shared/pics/yWPk9.jpg" does not exist

maybe the problem is Unity? I'll try changing desktops and let you know.

sorry, I didn't run the command with chooseRandomImages: True
changing this in the gui wasn't setting it here so I had to add the -images argument:

root@T420s:~# xscreensaver-getimage -verbose -directory /mnt/shared/pics -images root

now my results are similar to that earlier post

I also have this problem. xscreensaver gives "Directory dos not exist" on mounted SMB share.
Have tried making a link to the share and choose it, but "does not exist".
If I choose a local folder the local pictures works.

I have another PC that I use Xscreensaver on and on that it works fine with mounted SMB share.

The different between PC1 and PC2 is:

PC1 = Directory does not exist
PC2 = Works

PC1 = x86
PC2 = x64

PC1 = SMB server is a Netgear Stora
PC2 = SMB server is a Netgear RadyNas Ultra 2

Reproducible even with xscreensaver 5.18 on my i686 machine (client).

It seems that stat() on the line 1256 in get_filename_1() in xscreensaver-getimage.c returns -1 with errno 75 = EOVERFLOW. stat(2) says that this can happen when such application was not compiled with -D_FILE_OFFSET_BITS=64 and when using 32-bit platform. However while stat(2) says that this can happen when accessing too large file, this issue is not this case. For this case, EOVERFLOW happens because files on cifs-mounted system can return very large i-node : for people seeing this issue you can check this by "ls -ali" on cifs-mounted system.

For people seeing this issue: would you try either of the below?
* mount.cifs windows system with adding "noserverino" option
* Adding "#define _FILE_OFFSET_BITS 64" at the top of xscreensaver-getimage.c and recompile xscreensaver.

I mount.cifs the share from Netgear Stora on PC1 with adding "noserverino" option and now it works :D

I discussed this with the upstream developer and we agreed to add "-D_FILE_OFFSET_BITS=64" to compiler flags when building whole xscreensaver source. He is now thinking where to write this on configure.in.

Mamoru, thanks a lot for investigating this! We'll add "-D_FILE_OFFSET_BITS=64" in the next Debian version.

This has now been fixed in my Debian tree and will be released in Debian in 5.15-4 or 5.19-1. Debian is in release freeze at the moment, but I have uploaded a preview package "5.19-1pre" to my PPA if anyone would like to test it: https://launchpad.net/~tormodvolden/+archive/ppa

Note that with xscreensaver 5.21, AC_SYS_LARGEFILE is added to configure.in, so _FILE_OFFSET_BITS will be set to 64 in config.h{,in} if needed with doing configure, and modifying CFLAGS is no longer needed.

This bug was fixed in the package xscreensaver - 5.26-1ubuntu1
