I'm having a little trouble with Virtualbox and seamless mode with a Windows 7 guest VM. Fullscreen mode works fine but whenever I switch to seamless mode, the windows are just black boxes, though they can be moved. The preview window in Virtualbox shows things as expected. If I switch back out of seamless mode, the entire virtual monitor is black and I have to save the VM and start it again before it displays normally. Attached is an example of the black box where a window is.

Environment:
Dell Latitude E6540
Ubuntu Gnome 16.04
Virtualbox 5.0.22 r108108
Windows 7 Professional guest

I'm fairly new to Linux, having recently installed Xubuntu on my secondary computer. I'm coming from Windows 7 and am familiar with Truecrypt and have used it to encrypt file containers, non-system partitions and operating system partitions. I've managed to use it for nearly a decade without ever losing data, so I'm not a newb to encryption. But looking at dm-crypt and LUKS has got me wondering if I can handle encryption in Linux!

I'll describe what I'm trying to do and would appreciate some feedback on suitable options.

I have 2 computers - my primary computer is a desktop currently ruing Windows 7 and I'd like to move this to Xubuntu 16.04 as host and Windows 7 as guest (VirtualBox VM). My secondary computer is a laptop that runs Xubuntu 16.04 as host with Windows 7 as guest (VirtualBox VM).

On the laptop, I use GPT partitioning and LVM, and would like to use the same on the desktop.

System encryption isn't a huge deal for the desktop since I view risk of someone stealing or otherwise physically accessing the desktop as very low. And I can use encrypted containers for data I want to protect - though I've found container encryption is more of a hassle than system encryption because you have to mount and enter password every time you wish to access the data, while with system encryption, it's a one-time password entry when powering on the system. Also, with file container encryption, since some of the data I wish to protect must reside on the VirtualBox virtual disk, I'll have to install encryption software onto the Windows guest. With system encryption of the host, I'm guessing decryption of the host would decrypt the virtual disk, so no need to run separate encryption software on the Windows guest and the entire encryption process is invisible to the guest since all VirtualBox ever provides the guest is an unencrypted virtual disk.

System encryption becomes a bigger conce for the laptop where risk of theft is considerably higher. Similar to the desktop, the alteative to system encryption would be encrypted file containers in both the host and the guest. I could enable a BIOS password, but any remotely savvy thief will just remove the disk, thus bypassing the BIOS password protection.

LUKS:
As I understand it, support for dm-crypt/LUKS is built into Ubuntu 16.04 (and the various flavors such as Xubuntu), and I understand that it may have a speed advantage over a Truecrypt style encryption solution, such as Veracrypt. Seems there is not much in the way of GUI management and the user mostly ends up using the terminal to manage it. The thing that scares me most about LUKS is the waing I found in the cryptsteup FAQ: LUKS on partitions or raw disks?:

Be aware that if you add LVM into the mix, things can get very complicated. Same with RAID but less so. In particular, data recovery can get exceedingly difficult. Only do so if you have a really good reason and always remember KISS is what separates an engineer from an amateur. Of course, if you really need the added complexity, KISS is satisfied. But be very sure as there is a price to pay for it. In engineering, complexity is always the enemy and needs to be fought without mercy when encountered.

Yikes!

Veracrypt:
For my use, Veracrypt has the advantage of being familiar, since it is a fork off the discontinued Truecrypt project. It can also encrypt/decrypt existing system partitions, and has a very easy to use GUI. My conces with Veracrypt are:
1. does it play well with LVM?
2. is it noticeably slower to read/write than LUKS?

However, what it is doing with Ubuntu Gnome 14.04 and 16.04 installs (freshly updated, and for what it's worth, Fedora as well) is freezing up at completely random times. It seems to be regardless of the load it's having. I can't switch over to another console either, I have to forcefully shut it down and start it again. Doing some searching has some talks on disabling Bluetooth support but also recent keels not having the issue anymore, which I believe I have.

(For what it's worth, Windows is ruing 100% stable, also under higher load situations, so likely I can rule out any heat issues).

Would anyone mind giving me a hand looking for clues? Normally I do know quite well where to start but I honestly don't have a clue on where to start this time

I'm having trouble understanding how to upload a newer version to my ppa.
I've only just created a ppa and successfully uploaded my first deb.
I've made some changes in a couple of scripts in the package and want to update the ppa.

I understand you have to make a change to the debian/changelog to reflect the new version.
I did this (not even sure if thats the correct way to number)...

Hi all,
I recently set up a server with ufw firewall.

I have added a rule to allow port 21 access so Wordpress can install plugins.

I used sudo ufw allow 21
sudo ufw allow 21/tcp
and also sudo ufw allow proto tcp from any to any port 80

I have then used sudo ufw disable/enable to stopt/start it.

I have then also restarted the server.

For some strange reason it still does not allow FTP.

I have tried using FileZilla and putty. In putty i get a time out error and in FileZilla I get Coection attempt failed with "ECONNREFUSED - Coection refused by server".

Out put of ufw status so you can see

yet2lea@Yet2Lea:~$ sudo ufw status
Status: active

any ideas what I am doing wrong?

HI Community:

I bought an Android Samsung Galaxy S7 ... and put a 64Gb microSDXC card to augment its capacity. It is a new model Android, so it probably has the most recent Android operating system.... I don't know much about that.

I want to transfer music directories on my Ubuntu desktop that have music to the Android.

When I plug the Android into my Ubuntu desktop I don't see anything... no directories or anything.

Can somebody tell me how to transfer those music directories from my Ubuntu desktop to my Android's microSDXC card so that I can see them on the Android and play them?

Many thanks,
Old Jimma

Is it possible to use du command along with ls, so i can get better information what are folders and what are files, and info about ownership and permissions? Something like ls usage in Find command: find ~/ -ls

Also, in this listing i see files with kilobytes size in front of files with megabytes size. Why is that? I assume 'K' stands for kilobytes and 'M' stands for megabytes:

max@ubuntu:/var/cache$ sudo du -sh * | sort -nr
93M     apt-xapian-index
50M     apt
32K     fontconfig
20K     ldconfig
8.0K    dbconfig-common
8.0K    apache2
4.9M    debconf
4.0K    pppconfig
4.0K    apparmor
1.3M    man

Hello, I am using vlc 2.2.3 with RC (remote control) but I have no luck to change overlay logo image.

Commands like /bin/echo -n "pause" | nc -U /user/vlc.sock works ok but commands I tried for logo change are not working:

/bin/echo -n "@logo logo-file /user/logo2.png" | nc -U /user/vlc.sock
/bin/echo -n "@name logo-file /user/logo2.png" | nc -U /user/vlc.sock
/bin/echo -n "--logo-file /user/logo2.png" | nc -U /user/vlc.sock

Any idea how to change logo via RC please?

Hi all.

The network was ruing fine yesterday, but today it's not doing anything productive. I don't know what the problem could be.
The network card is detected and shows up with lspci, and eth0 is up, but doesn't appear to be 'ruing'.

ifconfig shows:

eth0     Link encap:Etheet    HWaddr 00:10:18:2c:13:b7
           inet addr:10.4.56.3     Bcast:10.4.56.255    Mask:255.255.255.0

Anyone know what all this could mean?

P.S. Sorry for the odd formatting. And I'll try a live-cd to make sure the card is working properly.

Current situation:
I have minimal installation of Ubuntu LTS currently 14.04, soon 16.04 too.
I have some exteal USB HDD (WD 2TB, Maxtor 0.5TB, ADATA 1TB). Now I thinking about central data storage accessible from Windows and Linux (in the best case in Android too).
I found WD MyCloud HDD I have not bought yer. It seems perfect, Etheet interface pro coection to router and USB (with a USB hub) for coection of old USB HDDs. But official support for Linux is missing.

I have already found:
http://www.huffingtonpost.com/dulio-...b_5121961.html
so I know that WD MyCloud could be accessible from lInux.

Questions:
1. Is it possible to access the old HDDs (any HDD, not specifically my ones) coected via USB to WD My Cloud in Ubuntu/Linux? Did you try anyone?
2. Is it possible to set up backup of WD My Cloud to exteal USB HDD coected to WD My Cloud automaticaly? At least to one of them?
[3. Is is possible set up and manage the HDD from linux (or should done only from Windows). There is a web interface but I didnt find any documentation for that. But it is optional, I can manage via Windows.]
4. Do you know any similar solution supported by Ubuntu like WD My Cloud (Etheet drive with USB and automatic backup to them [for reasonable price])?

I am newbie on this forum please consider if I made anything wrong (I appreciate any notes about that).
I am rather newbie in Linux, I like instruction for dummies.

I've been searching the web for hours on this, and there seems that there's no solid fix.

If I reboot my system after logging in to it, my WiFi won't automatically coect, which makes making my system a headless SSH server a little difficult. Once I log in to it however, the system automatically coects to my WiFi and all is good.

What I'm wondering is, is there a way to have Ubuntu 16.04 automatically coect to my WiFi without having to manually log in to the system? If I try to click on the wireless icon at the log in screen, I get a screen saying "Failed to add/activate coection".

1) git clone httpxx//... downloads the entire git repository, including all change history, to your computer; saving it to a local git repository in an automatically-determined directory name.

2) You can't git clone a .zip file's contents as far as I know, certainly not if it's not a git repository. Two things you can do though: A) just unzip it and use the result, B) use your local git repository (the result of the git clone) and git checkout the last "good" revision (see man git-checkout for more information on how that works).

I've been trying to set up luks full disk encryption on two computers (hp pavilion acer vertaron)
I was trying to set up luks on only part of the drive originally but now I've found that using luks on the entire drive is just failing to boot to grub.
With the alteate lubuntu 16.04install disk I get no errors during install but it hangs with that dark blue screen and noting else.
With the desk top install 16.04 I get errors to tu swapoff to various partman errors and an outright failure to install grub with the dialog to change grubs location failing to respond to any action.

I've tried the two systems I readily have accessible to test on with various sata hard drives ranging in size from 80gb to 500th

All with the same end result.
Not a bootable system.

Is any one else having issues installing with luks guided full disk encryption.
(No point even trying to find an up to date tutorial to setup luks sharing a hard drive with Any other partitions if the basic install is broken)

Or is it just me.

(We are taking I took both systems down to just motherboard and one hard drive. Booting from a sub stick. Checked my iso images with the md5 they are fine, the systems are offline systems)

Hi, i have ubuntu 16.04 installed and i wanted to install Windows 10. I installed it and it skiped the grub and went straight to Windows 10, i grabbed a copy of boot-repair usb disk and tried to run recommended settings but i got this error:
GPT detected. Please create a BIOS-Boot partition (>1MB, unformattedfilesystem, bios_grub flag). This can be performed via tools such as Gparted.Then try again.

After an hour of so of trying things i finally managed to boot into ubuntu ruing this:
bcdedit /set {bootmgr} path EFIubuntushimx64.efi

but now i can't boot to windows, can't run boot-repair in recommended settings, in advanced settings tried settings sda1 (where the UEFI partition is) but grub2 isn't detecting my windows. Also, i have one entry of an old windows that's incorrect.
Here's my bootinfo summary generated from boot-repair:
