I am unable to remove my files from .Trash/ folder on my external hard drive. The file system is NTFS. Files are not in use by any process, therefore might not be locked.

Empty Trash menu entry on the trash icon opens an empty file manager, endlessly loading the list of files.

When launching nautilus with sudo it displays:

This location could not be displayed. 
Sorry, could not display all the contents of "Trash:///": Operation not supported

sudo rm -rf /path/to/.Trash-1000/* results in

cannot access '.Trash-1000/expunged/2836763541/timing': Input/output error
rm: cannot remove '.Trash-1000/expunged/2358660437': Directory not empty
...

What can I do to empty .Trash/ folder on external drive?

I am trying to open a .pdf file with FoxitReader from the terminal.

The following works on the terminal:

/opt/foxitsoftware/foxitreader/FoxitReader "Document.pdf"

But this doesn't:

/opt/foxitsoftware/foxitreader/FoxitReader "Document.pdf /A page=5" It launches the FoxitReader GUI application, displaying "the file could not be found". The document has more than 5 pages.

• Foxit Reader version is 2.4.1.0609
• Ubuntu 16.04

is this option not available for linux systems? Did the syntax change? Do I need to install a plugin?

I also tried

/opt/foxitsoftware/foxitreader/FoxitReader -h
/opt/foxitsoftware/foxitreader/FoxitReader --help

but it fails to open these, too :(

Edit: I attempted the same in Adobe Acrobat Reader

/opt/Adobe/Reader9/bin/acroread /A "page=3" "Document.pdf"

with the same result. As always, instructions are documented for windows. I tried a couple of other PDF viewer now...

is there any free PDF reader able to:

• run in linux
• open PDF at a specific page
• highlight text
• display page in full view (optional)

?

thank you

I'd like to use a location different to my home directory for recording videos using SimpleScreenRecorder. However, when I "Browse..." File -> Save as: I get the following error message:

Could not read the contents of media
Error opening directory '/media': Permission denied

as soon as I browse into '/media' folder.

I already changed ownership of the folder from root to $USER, still the same. When I try to launch the application from the terminal using sudo or gksudo it fails to launch the application with

sudo

mkdir: cannot create directory '/run/user/0': Permission denied

gksudo

(gksudo:19480): Gtk-WARNING **: Unable to locate theme engine in module_path: "pixmap",
No protocol specified
simplescreenrecorder: cannot connect to X server :0

I am using Ubuntu 16.04.

Everything works fine when I use my $HOME directory. I'd prefer to use the application without root permissions if possible.

For testing only I temporarily set /media permissions to 777 and it still did not work.

Please advice, thank you

I can not delete files by pressing 'Del' key on my keyboard. I don't know why that is. The files are mounted on an external drive that auto mounts at system startup. The drive can be mounted by any user, filesystem is NTFS.

I chose NTFS so I can access the files from a windows OS if needed.

all files have 777 permissions for root:root.

I can delete the file with right-click, delete. I can also delete the file using rm without sudo.

What I cannot do is select the file and press 'Del'.

the operating system is Ubuntu 16.04.

I have an internal drive with a partition I am no longer able to access:

You do not have the permissions necessary to view the contents

Reason for it is a windows OS with fast boot. There are many solutions provided for this but none of them worked.

sudo mount -t ntfs-3g -o ro /dev/sda4 /media/windows/ NTFS signature is missing. Failed to mount '/dev/sda4': Invalid argument The device '/dev/sda4' doesn't seem to have a valid NTFS. Maybe the wrong device is used? Or the whole disk instead of a partition (e.g. /dev/sda, not /dev/sda1)? Or the other way around?

ntfsfix ends in unrecoverable error:

sudo ntfsfix /dev/sda4
Mounting volume... NTFS signature is missing.
FAILED
Attempting to correct errors... NTFS signature is missing.
FAILED
Failed to startup volume: Invalid argument
NTFS signature is missing.
Trying the alternate boot sector
Unrecoverable error
Volume is corrupt. You should run chkdsk.

.

sudo fsck /dev/sda
fsck from util-linux 2.27.1
e2fsck 1.42.13 (17-May-2015)
ext2fs_open2: Bad magic number in super-block
fsck.ext2: Superblock invalid, trying backup blocks...
fsck.ext2: Bad magic number in super-block while trying to open /dev/sda

The superblock could not be read or does not describe a valid ext2/ext3/ext4
filesystem.  If the device is valid and it really contains an ext2/ext3/ext4
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
    e2fsck -b 8193 <device>
 or
    e2fsck -b 32768 <device>

I tried e2fsck but that did not work.

The only working solution is to boot into windows and disable fast boot, but I can no longer boot into windows.

I only want to recover my user data somehow is there a way?

Edit: Meanwhile I deleted all partitions with only Data left. This is how it looks like:

thank you

In Lattice Diamond I receive the following message in the terminal:

in order to open a html file from the "help" menu.

my LD_LIBRARY_PATH is empty, and the missing library is installed on my system:

so I added it to my library path and restarted the application. It did not help:

in system settings -> monitor I only have 1 monitor shown (build-in). I have 2 external monitors connected, this is my current monitors.xml:

I get the following error message on xrandr:

xrandr: Failed to get size of gamma for output default

        v: height 1080 start 1083 end 1088 total 1120           clock  59.96Hz

Note that 77 Hz is not officially supported by the manufacturer of any of my monitors.

The monitors are both working at 1080p_60, but the desktop is mirrored. I want to change it to expand the desktop area.

Also, can I delete the

  <output name="HDMI-2">
  </output>

part? My monitor connection is named DP-1, shouldn't it be VGA-1, instead? Don't have DP and physical connection is VGA cable. I don't have a xorg.conf file, I deleted monitors.xml and rebooted -> the 77 Hz are still there.

Thank you!
