I'm using Xubuntu and connecting over RemoteDesktop with Windows 7.

Everything works fine, but the auto_completion in my bash doesn't work. I checked the .bashrc file in my home directory and also the /etc/bash.bashrc.

I uncommend the lines below in my local bashrc configuration and also in bash.bashrc, but nothing changes.

if ! shopt -oq posix; then
  if [ -f /usr/share/bash-completion/bash_completion ]; then
    . /usr/share/bash-completion/bash_completion
  elif [ -f /etc/bash_completion ]; then
    . /etc/bash_completion
  fi
fi
  • I am very curious as to why this only shows up on remote sessions but not on sessions directly logged in on the console. It happens with either VNC or XRDP - which is not surprising as behind the covers XRDP just invokes VNC to do the rendering. It is I presume because the X server built into VNC is different from the Xorg one but it is still puzzling why this occurs - after all the change suggested here should only affect the "Super-Tab" key combo not the simple "Tab" key. Does this imply that somehow VNC is always showing the "Super" key depressed when tab is hit? And as a final point, I hav – user273641 Apr 24 '14 at 14:19
  • This issue is still present in Xubuntu 14.04 when using VNC. And implementig the change fix the issue. Remember to search the second occurence of "Super> Tab" like explained in the steeldriver answer; it's in the "custom" section. – user294420 Jun 17 '14 at 17:15
  • @user294420 I couldnt quite understand the change to be employed can I have a little more explanation? – Sohaib Sep 6 '14 at 6:47

You may find that this is a more general issue with interception of the Tab key under remote XFCE4 sessions, rather than a problem with bash completion itself.

I had a similar issue running XFCE4 over VNC and the workaround for me was to edit the ~/.config/xfce4/xfconf/xfce-perchannel-xml/xfce4-keyboard-shortcuts.xml file to unset the following mapping

<       <property name="&lt;Super&gt;Tab" type="string" value="switch_window_key"/>
---
>       <property name="&lt;Super&gt;Tab" type="string" value="empty"/>

Note that there may be two entries, and the first already has the value "empty". If this is the case, edit the second entry.
I found this solution online somewhere and can't really take credit for it.

    Good shot, but i found this issue also with google. This property has already this value at my xfce4-keyboard-shortcuts.xml by default. The link: codebangers.com/?p=134 – nik the lion Oct 1 '13 at 15:59
  • Damn. I wounder why this value is by default "empty". Checked this with less and find a second entry. But this time with the value "switch_window_key". Changed > restart > works!!!! Thank you :) – nik the lion Oct 1 '13 at 16:09

    Edit that file and replace switch_window_key with empty on that line. I used nano to edit the file. I then restarted VNC with sudo service vncserver restart. It just worked for me. – Cameron Taggart Oct 27 '15 at 21:12
  • I was sure this was an RDP issue. I was wrong. Thanks for this. – Jon Carter Jul 26 '17 at 1:43
