Background: OEM install of Ubuntu 18.04 on a Dell Latitude. Note that this not an install of Ubuntu by the OEM, rather, Ubuntu 18.04 was installed by me using the "Install as OEM" option.

While exploring the menus the user clicked on something that upon next boot changed the OEM install into a regular install, with a username other than oem. He was prompted with the regular install screen and filled it out to the best of his ability. In no place was there a warning that data would be lost. The system was immediately shut down and I have the drive now mounted read only on my desktop.

Now that this is converted to a regular install, how might one go about recovering the data that was in /home/oem/? Note that extundelete could not find anything deleted on the disk, but I do see that the custom /opt/ directory with third party applications is still intact.

I used autopsy to scan the drive and I do see that there is a file (not a directory) called /home/oem/ but its contents do not seem useful: https://pastebin.com/XXCiu7Bb

I have also tried opening the partition with testdisk (Photorec tool) but also there I see the file /home/oem but not the directory /home/oem/ which I know to have been the home directory of the OEM user. Possibly I created this file by accident in an early stage of the recovery process while it was still in the laptop, but now I have the drive mounted read only on another computer. Yes I am aware that some data may have been lost due to the drive having been mounted read-write.

How might I recover any files that the user had in the OEM install? I would be happy with anything from the /home/oem/ directory that no longer exists, but mostly text and ODT files if possible.

It seems that some KDE features, such as Attach as Tab, are windows decoration dependent. Specifically, the otherwise excellent Plastik windows decoration does not support Attach as Tab.

The default windows decoration, Oxygen, does support Attach as Tab however the titlebar colour is a dull grey and that makes it difficult to determine which window is the active window when many windows are open. Oxygen ignores the configured titlebar colour.

Which available KDE themes support both titlebar colour and Attach as Tab? Is there any way to check these features before downloading and installing each theme individually?

I have a function that I run often from the CLI, so I gave it the short name t:

$ which t
/home/dotancohen/.bin/t

$ cat `which t`
#!/bin/bash
ctags-exuberant -f php.tags --languages=PHP -R

$ ls -lh /home/dotancohen/.bin/t
-rwxr-xr-x 1 dotancohen dotancohen 316 Jan  3 16:58 /home/dotancohen/.bin/t

$ echo $PATH
/home/dotancohen/.bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/home/dotancohen/.rvm/bin

However, when I try to run the program, I get a message that I should install another app that also uses the name t:

$ t
The program 'task' is currently not installed. To run 'task' please ask your administrator to install the package 'taskwarrior'

How can I have Bash run /home/dotancohen/.bin/t when I enter t?

Many of the questions asking how to create an animated gif from a set of png images suggest to use a variant of ImageMagick's convert command:

convert -delay 2 -loop 0 *.png animated.gif

However, I have a few thousand images and thus convert uses up all my memory, swap, and then crashes. What alternative software exists, which is more memory-conscious? I could use another open format if .gif is not supported, and I do prefer a CLI tool.

I have a Beats Studio Wireless bluetooth headset that intermittently cannot connect to Kubuntu 14.10. This is what is happening:

If I continually click the Blueman system tray icon's "Recent Connections -> Audio Sink on Beats Wireless" option, then eventually the headset will connect.

I am installing the latest FFmpeg from this guide:

In some places it suggests performing make install without sudo, here is a single example of several:

cd ~/ffmpeg_sources
wget http://download.videolan.org/pub/x264/snapshots/last_x264.tar.bz2
tar xjvf last_x264.tar.bz2
cd x264-snapshot*
PATH="$PATH:$HOME/bin" ./configure --prefix="$HOME/ffmpeg_build" --bindir="$HOME/bin" --enable-static --disable-openclcd ~/ffmpeg_sources
wget http://download.videolan.org/pub/x264/snapshots/last_x264.tar.bz2
tar xjvf last_x264.tar.bz2
cd x264-snapshot*
PATH="$PATH:$HOME/bin" ./configure --prefix="$HOME/ffmpeg_build" --bindir="$HOME/bin" --enable-static --disable-opencl
PATH="$PATH:$HOME/bin" make
make install
make distclean

Should I being using sudo make install instead ?

My intention is to make the packages available for all users, including Apache/PHP.

My KDE system tray icons are huge in Kubuntu 14.04:

Notice that the Skype and wicd icons are sized properly, these are not KDE apps. However the KDE apps' icons (Klipper and Volume Control) are huge. I have checked and I already have the "Improve systemtray on HiDPI displays" patch applied on my system:

Considering that I already have the patch, what might be the cause of the huge KDE System Tray icons?

Due to an accessibility bug in the latest versions of Ubuntu I will have to revert back to Ubuntu 12.04 LTS when 12.10 is retired later this month. I see that Ubuntu 12.04 came with Firefox 11.0, LibreOffice 3.5, and other outdated (functionality-wise) software.

Though I have no problem compiling Firefox, LibreOffice, and other apps, I would like to know how could I find out what the currently available software versions are. How could I check this before installing Ubuntu 12.04? I suppose that at least Firefox would have been updated (due to Mozilla update policy), but I would like to check first before I install.

Is there some way to query the Canonical repos for the latest software versions available for 12.04 from my current 12.10 system? Would it be easier to check from some web interface on Launchpad? I'm looking for something similar to aptitude show foobar, but for which I could specify the distro version that the results would be returned for.

I could install a virtual machine to check, but I find that cumbersome and not really practical as a day-to-day solution should I ever need to do a similar check in the future.

I am a KDE user thinking about moving to Unity. Due to manual disability, I use sticky keys and in KDE I have an applet in the system panel which shows which modifier keys are active. I remember that Gnome had this feature as well, so do Windows and OS X.

How does one ad the keyboard modifier state applet to the panel in Unity?

Clarification: I have already enabled sticky keys. I am asking how to add an applet which indicates the state of the modifier keys. This indicator would show when the Shift key is depressed, when the Alt key is depressed, when the Tux key is depressed, and when the Ctrl key is depressed. This applet exists in all major desktop environments (KDE, Windows, Mac OSX, and Gnome). It is necessary for accessibility of the desktop.

Here is an image of the keyboard modifier state applet, next to the keyboard layout indicator applet. The modifiers represented are, from left to right, Shift, Ctrl, Alt, I-dont-know-this-one, Tux/Win, NumLock, and CapsLock. It can be seen that the NumLock key is active.

On Kubuntu 12.10 I can see with the KDE System Monitor Plasmoid that the CPU usage is fluctuating between 60% - 90% on both cores. As soon as I open top it goes down to 3% - 10%. I thought that the issue is that I'm 'doing nothing' while looking at top, so I closed top (just pressed q) and still did nothing with the keyboard nor mouse. However the CPU usage jumps back up to where it was. What might be smart enough to calm down while top is running?

When trying to install tmux I get an error that Untrusted packages could compromise your system's security, similar to the situation in this thread. I ran aptitude update and the package installed without issue, but I am concerned that the update may have been compromised. My concern in enhanced as I see that the update was done without SSL (http address):

EDIT: I have now been made aware that the targeted attacking of Israeli websites on April 7 has already begun. Therefore, there is increased suspicion of a compromised server. I could find more information about the attack if necessary, though I don't see much mention of it in widespread English-language news websites.

Clarification: I'm asking how to ensure that what I've already downloaded and installed is not compromised. I am not asking how Canonical ensures the security of repos.

When a user has a Skype chat window open but closes the main Skype window (the contact list), then clicking the Skype icon in Unity only restores the chat window, but not the main Skype window (the contact list).

How can one restore the main window without closing the chat window?

On a LAN each computer is assigned a different IP address each morning. When I installed Kubuntu 12.10 the IP address assigned to the machine was 10.0.0.2, but today it is 10.0.0.1. When I try to connect to http://127.0.0.1 in Firefox I see in the status bar Connecting to 10.0.0.2. However, there is no mention of that address in the /etc/hosts file:

127.0.0.1       localhost
127.0.1.1       bruno

# The following lines are desirable for IPv6 capable hosts
::1     ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters

Note that setting the DHCP server to assign the same IP address per MAC address cannot be done as the router is unplugged each evening (electrical issues in the building) and loses the settings.

I have installed Kubuntu 12.10 on a new computer. Every few hours of work, the system locks up. The keyboard and mouse are unresponsive, and the screen does not change even if there are screen elements that should change (such as a countdown timer or the system clock). I cannot use Ctrl-Alt-F* to get to a terminal. The hard drive light flickers briefly once every 10-15 seconds, this is a much slower pace then is observed when the system is functioning properly.

The applications running at the time of lockup include: Skype, RSIbreak, Zim, Anki, Firefox, Konsole with an active SSH session, apache2, mysqld, and of course KDE. The issue has occurred with 2 different keyboards, but I have not tried a different mouse yet. As these are the tools needed for work, I cannot simply run for a few hours with them disabled to see if any are the 'guilty party'. The lockup occurs both while I am actively typing on something, or if I have stepped away for a few minutes.

• Gigabyte F2A55M-HD2
• GeForce 210
• AMD processor, 4 GiB memory, 1 TB hard drive, 500W power supply

More detailed hwinfo can be found here.

I plan on running memtest overnight. What else should I check, and how might I get a log of the problem?

EDIT: The system just locked up again with only Firefox, Chrome, Konsole and KDE running. Here is the syslog.

It seems that smbmount is not available in Kubuntu 12.10:

 - neptune():~$ smbmount //192.168.0.100/ samba/ -o rw
smbmount: command not found
 - neptune():~$ apt-file search smbmount
manpages-zh: /usr/share/man/zh_CN/man8/smbmount.8.gz
manpages-zh: /usr/share/man/zh_TW/man8/smbmount.8.gz
 - neptune():~$ aptitude search smbmount
 - neptune():~$

Furthermore, I cannot seem to use smbfs to mount:

 - neptune():~$ sudo mount -t smbfs //192.168.0.100/ samba/ -o rw
mount: unknown filesystem type 'smbfs'
 - neptune():~$ aptitude search smbfs
 - neptune():~$  

Any ideas how to continue?

When I moved to Ubuntu I worked hard to get out of the habit of working as root. However, is the situation below an example of one of the few times that a user should become root?

 - neptune:~$ cd ../testuser/.kde/
bash: cd: ../testuser/.kde/: Permission denied
 - neptune:~$ sudo cd ../testuser/.kde/
sudo: cd: command not found

Note that I do happen to have the password for testuser, however I feel that working as root is preferable to suing to testuser.

Thanks.

EDIT: Upon researching solutions I see that my best course of action is to just su to the user whose files I intend to start scripting on.

It seems to me that I have the proper permissions, so why can't I create directories in my $HOME directory?

dotancohen@neptune:~$ whoami
dotancohen
dotancohen@neptune:~$ pwd
/home/dotancohen
dotancohen@neptune:~$ ls -l .. | grep dotancohen
drwxr-xr-x 16 shelly shelly  4096 Jul  2 15:02 dotancohen

I am having a hard time with a Kubuntu 12.04 install that does not have an internet connection. In order to build the ethernet driver, I need gcc. I installed from the DVD, and I have gcc-4.7-base installed but that does not provide a gcc executable? Should I just make a symlink? How should I install gcc otherwise?

Thanks.

EDIT: Here are some attempts to install GCC. The CD-ROM repo is enabled in /etc/apt/sources.list, and the full DVD is in the drive.

shelly@neptune:~$ sudo apt-get install gcc

I just bought an ASUS P8H61-M LX motherboard. This motherboard comes with a Windows driver package to enable the onboard ethernet port. My troubles with this board are documented here and here. After installing Windows the LAN did not work either, but after installing the supplied driver disk in Windows the LAN was then enabled.

I have been googling for the Linux driver but cannot find it. I see that others have used this motherboard in Linux, so apparently it is possible. I wrote to ASUS but I do not expect a reply for 48-72 hours.

A new Kubuntu 12.04 install is not getting IP addresses from either the wired connection nor from any wireless connection. The cables / router ports / wifi adapter / access point are all known good and work with other equipment. I suspected a failed NIC but seeing how the wireless connections also aren't working via USB wifi adapter, that eliminates the NIC as a possible source of the issue. What other hardware might be shared between the wired (onboard NIC) and wireless (USB wifi adapter)? I stress that with the wifi adapter I see other networks, but cannot get an IP address from them either. Testing with a Kubuntu 11.10 LiveCD has the same results.

I notice that there is no /etc/dhcp/dhclient.conf file.
