A while back I installed i3 on my MATE box, and I'm quite happy with it, however despite disabling Caja Desktop (x-caja-desktop) when setting i3 as the default window manager through dconf editor, every time I install a .deb package via the gui installer, the desktop "window" opens and overlays my entire screen. This is incredibly annoying, and hitting super-shift-q to close the window doesn't work, which forces me to just move it to an unused workspace. Is there anything I can do to stop this from happening without installing a different file manager?

I use caja often with two windows open at the same time, each exactly half the screen. By default, caja opens with a window a bit to the right, not exactly half the screen. The next caja opens a window on top. However, if the first caja window is reduced to half the screen to the left, the next opens in the right half. Thus, how do I have the default location for the first caja open to the left half of the screen? I experimented with caja --geometry=960x1080 . (half my screen in pixels), but it was not doing what I wanted. Two questions: 1. What is the correct geometry value for a screen 1920 by 1080? 2. How do you have caja open in the top left corner?

How can I change the size of the font in the bottom bar of caja windows without changing the global "Application font"? I mean the font that says how many items there are in a given folder and how much space is left on a given device: see the screenshot: This font seems to be linked to "Application font", but is significantly smaller (it's probably defined as ApplicationFont.size - 3 or something like that). I would like to increase its size to match the normal size of "Application font". I'm guessing this will require editing some theme config file, but I have no idea what file exactly nor what the key for this specific font could possibly be...

When in nautilus or caja I click on the icon of an encrypted disk and enter my password, the underlying block device gets mapped to /dev/mapper/luks-$UUID and it gets mounted at/media/$USER/$DISK, no root password required. Is there a way to invoke this process from the command line, without GUI, including obviating sudo and having the mountpoint able to get unmounted again from GUI.

Recently, caja refuses to "mount" smb locations for which it previously gave no complaint. Usually, I would access various share points using caja by typing smb:/// in the Location text-box. When the credentials dialogue window opened, I would type my username, domain and password as appropriate for the company. Usually, this was sufficient but no longer. Now, I do that same process and the dialogue window immediately re-appears asking for the same information. It simply will not take the credentials. I can mount the same share point using mount from the command line, using the exact same credentials, without issue: sudo mount -t cifs -o credentials=,uid=andy /// . What might be causing this? Oh, also, where would caja be writing its logs? I can't find anything relevant in dmesg and listing the contents of /var/log wasn't as fruitful as I'd hoped.

There should be a tool to create such actions in Caja (default file manager in Mate desktop environment), installed with sudo apt install caja-actions But it doesn't seem to work, as indicated here . In my case, this tool is in the start menu, but it doesn't launch (Mint Mate 18.3, based on Ubuntu 16.04). How to create such actions manually? --- This is posted in order to provide an answer.

In caja it seems there is no way to add a folder to the Places menu. I tried caja help menu > F1 but didn't get anywhere. Any help would be appreciated. This is in caja 1.20.0

I know how to manipulate the position of desktop icons with the

set

command

set -t string '/home/user/Schreibtisch/example' 'metadata::cajas-icon-position' '500,500'

But this does not works with samba-shares. I also can't find the samba-shares in

~.local/share/gvfs-metadata/

(where are external drives) How dows one manipulate the Icons of samba-shares on Caja Desktops with gio?

I have done these procedures to mount my .img file in /etc/fstab (for ubuntu mate 20.04 x64) Create .img file :

dd if=/dev/zero of=filename.img bs=1024 count=2M
sudo mkfs.ext4 filename.img

Note: also be done with gparted with this method **The problem:** Mount /etc/fstab in /mount/point:

/home/user/filename.img /home/user/vdisk ext4 defaults 0 0
# or
/home/user/filename.img /home/user/vdisk ext4 loop 0 0
# or
/home/user/filename.img /home/user/vdisk auto loop 0 0

But always show 2 units: vdisk (mount) and loop (not mount) (see image) if i try to click on this other drive showing unmounted i get the following message: Why doesn't it just show the fileimage.img image mounted in the vdisk folder? **I would like you to help me fix the fstab line so that two units do not appear when mounting .img but only one** **Update:** if I run any of the following commands:

sudo mount -a
# or
sudo mount /home/user/vdisk

The same thing that I describe in my post appears. My fstab (I have altered the UUID for security reasons):

# / was on /dev/sda2 during installation
UUID=9f92d1aa-458d-441a-b349-abcdefghijkl /   ext4    errors=remount-ro 0       1
# /boot/efi was on /dev/sda1 during installation
UUID=F798-ABCD  /boot/efi       vfat    umask=0077      0       1
/swapfile          none            swap    sw              0       0
/home/user/filename.img /home/user/vdisk ext4 defaults 0 0

List:

sudo losetup --list | grep filename.img
/dev/loop8     0      0    1  0 /home/user/filename.img   0     512

**Important:** But, if I remove the /etc/fstab line, delete /dev/loop8 and mount .img image manually (with the followings commands), the described error does not appear

sudo mount -o loop /home/user/filename.img /home/user/disk
# or
sudo mount -t ext4 -o loop /home/user/filename.img /home/user/disk

**Workaround:** 1. manually mount .img manually to /dev/loopXX available:

losetup -f
/dev/loop8
sudo losetup -P /dev/loop8 filename.img
sudo losetup -l
/dev/loop8         0      0         0  0 /home/user/filename.img                            0     512

edit /etc/fstab and put the line:

# /path/to/loop/device       /path/to/mount/point       auto       loop       0 0
# example:
/dev/loop8 /home/user/disk ext4      defaults      0 0

and: sudo mount -a Note: this method is not permanent 2. bash script:

#!/bin/bash
mount -o loop /home/user/filename.img /home/user/disk

# sudo crontab -e
@reboot ./mount-img.sh

Another bash to mount/umount .img HERE (can be programmed in crontab to start with the system) 3. with bindfs:

sudo mkdir /mnt/disk
# edit fstab and add line:
/home/user/filename.img /mnt/disk ext4    defaults	0	0
sudo mount -a
sudo -u user bindfs -n /mnt/disk /home/user/disk

**Summary:** - There is no error - The image is mounted (manually and with fstab) **About mount:** When mounting the .img in fstab, it appears **duplicated** (one is mounted and the other is not). This does not happen when mounting the .img manually or /dev/loopXX in fstab **Update New:** This appears to be a bug in Ubuntu Mate 20.04.3. In Ubuntu version 20.04.3 this problem is not present. **testing file managers:** affects: - caja - nemo - thunar does not affect: - dolphin - nautilus launchpad report github issue Reference

I am running/using mate 1.20.2 amd using caja as my file and folder explorer (GUI-based) . I have tried to figure out where caja puts it preferences but have failed. $ caja --version MATE caja 1.20.2 I tried to first see in .config/caja if it has what I'm looking for - ~/.config/mate$ ls eom panel2.d Neither of the two folders had anything interesting contents. Then I tried - :~/.cache/mate$ ls background and even there I couldn't find any info. I also looked at dpkg -L caja and saw /usr/share/metainfo/caja.appdata.xml but could not find anything which explains where it might be. Even the F1 built right in caja doesn't tell anything . Can somebody help to find out where it is ?

I run [Caja](https://www.google.com/search?q=Caja+File+Manager&oq=Caja+File+Manager&aqs=chrome..69i57j0l6j69i60.2323j0j4&sourceid=chrome&ie=UTF-8) on CentOS7 and wondered if I could add a shortcut down the left side to a folder (acting as a (network)drive) or replace the 'Desktop', 'Documents' etc. shortcuts down the left side with my own shortcuts and/or rename them. Thanks

As a new Linux "superuser" trying to migrate from Windows 7 I have resisted asking basic questions that can be answered by searching, but I am stuck on this. When I create an executable file from C with gcc in the Linux terminal, called say hello.exe it is given X permission. Then from the terminal I can run ./hello.exe no problem. But when I try to run it from Caja it just shows its components as a text file. I can, however, select "Run as administrator" but then I have to enter my login password. This is irrespective of which of these two settings is enabled: - Run executable text files when they are opened. - View executable text files when they are opened. I leave it as the second setting though, otherwise I get asked what I want to do every time I view or edit a text file. I have tried to launch Caja from the terminal with sudo caja (needs password) but then, Caja won't run the executable *at all* because the Run option is no longer there. How can I run an executable from Caja directly: with a double-click? Edit: Can you run an executable from *any* file manager with a simple double-click? Edit 2: Now running Mint Cinnamon with Nemo file manager but the question is basically the same. Am I missing some setting that allows an executable to be run directly? Edit 3: During my research I found [**GNOME Is Removing the Ability to Launch Binary Apps from Nautilus**](https://www.omgubuntu.co.uk/2018/05/nautilus-remove-ability-launch-binaries-apps) : > "Or, to put it another way, you won’t be able to double-click on programs, scripts or apps to launch them using Nautilus." (*May 2018*) And as I suspect that the file manager authors develop them as derivatives of open source code (or perhaps use common system components), perhaps none of them now do. I also found this Wikipedia page [Comparison of file managers](https://en.wikipedia.org/wiki/Comparison_of_file_managers) has various tables. The one called [File features](https://en.wikipedia.org/wiki/Comparison_of_file_managers#File_features) has the last column as "Run executable files" so I tried out several of those file managers. - *None* of them would run an executable file which I have compiled (and some of them won't even allow easy access to my work drive – which is never the system drive). But anyway, I have discovered an easy work-around for now, which is that my favourite text editor Geany will run an executable of the current source file, if it exists, from a single click or F5 keypress, without making it into a project.

Newly created files and directories with the CAJA browser (e.g. in MATE desktop in Debian 9) seem impervious to whatever umask setting you set in /etc/profile. Where can I change the default permissions of the newly created files and directories by the CAJA browser?

I know about that [question](https://askubuntu.com/questions/117452/how-do-you-add-open-in-terminal-to-the-right-click-mouse-menu-for-folders-dire) , but how to do this in caja ?

Due to testing several programs I've ended up with a lot of entries on Caja's "open with list" menu when opening files. How does one edit that list in order to remove undesired entries?

Caja has a tendency of leaving zombie terminal processes behind, which is a nuisance when working with removable media. Caja pops up when the media is inserted, but then it is impossible to unmount and eject media as the zombie bash has an open handle on it. Is it possible to disable the terminal part of caja permanently?

I'm using **Ubuntu Mate 19.04 Disco**, using **MATE Caja 1.20.3**. Recently after a system update (think from **18.10** to **19.04**) the behavior of the open file/close file GTK dialogs changed: When I typed something previously there, it searched within the local directory and that only. Now it searches recursively, annoyingly not even displaying local matches on the very top and it annoys me tremendously. However, I do not know what this official "deep search" feature is called so I cannot seem to find the correct terms to disable it. What is this called and how can I shut it off?

Since my main data is not in $HOME, I have made a small (executable) script to start the GUI file manager (caja) in the desired directory and put it in my local executable directory (~/.local/bin): #!/bin/bash /usr/bin/caja /datadir To supersede the standard command caja, the script has the same name and the path to my local executables is listed first in my ~/.profile: if [ -d "$HOME/.local/bin" ] ; then PATH="$HOME/.local/bin:$PATH" fi Works fine so far, BUT whenever I log in the file manager is opened by default. No session saving is activated, no other executable from that directory is executed (tried a few echo-scripts and even other GUI commands). How can I suppress this behaviour? Using MATE as DE on Debian 10 (testing)

How can I set custom application which is being invoked when I press "Differences" button in "File Conflict" dialog? I did not find corresponding option in "File Management Preferences". I did not find it using "dconf Editor" in org.mate.caja.*. I did not find it in files located at /usr/share/caja and ~/.config/caja. Where is this option being stored at?

I'm using icons to categorize my folders but sometimes I move the icons to a more appropiate place so the next time I load the folder, the folder icon isn't set. Could I edit manually (replace text) the folder configuration to avoid searching its icon again? Where are those files? Could I edit also view mode for a certain folder manually (changing a value inside a file)?
