Hi all, since LL 3.0 is based on Ubuntu 16.04 is trim enable by default just like Ubuntu 16.04 is? Just install and LL 3.0 will do the rest?
If it is enabled by default will every brand of SSD get trimmed? I'm using a Corsair SSD.
Thanks.

First we will cover, as simply as possible, setting up an SSH tunnel to connect to x11vnc via Remmina and enabling a Linux Lite remote desktop on another Linux OS computer. Since in previous tutorials we have already installed and enabled both x11vnc server, and SSH server on our Linux Lite 3.0 computer, and previously enabled an ad hoc wifi connection between the two, this first instruction will be simple and brief. Again you will have to disconnect from the Internet, so make a copy of this tutorial in a Libreoffice document for use off line.
First open a terminal on your Linux Lite 3.0 computer. Type in the command below, and enter your password when prompted, and then hit enter, and your SSH server will start.
sudo systemctl start ssh
Next find and select your ad hoc wifi connection we created in the previous tutorial, and connect your two Linux computers together. Once connected type the command below into the terminal, and hit >enter, and x11vnc server will start.
x11vnc -once -loop -localhost -noxdamage -repeat -rfbport 5900 -shared
Now go to the computer running another Linux OS, and locate and open up Remmina. Click >Connection and from the drop down menu select >New and the Remote Desktop Preferences window will open. In the box to the right of >Name type in the netBIOS name of your Linux Lite 3.0 computer. In the box to the right of >Group type simply / (a forward slash). In the box to the right of >Protocol select >VNC – Virtual Network Computing. In the box to the right of >Server type in the IPv4 address of your Linux Lite 3.0 computer on ad hoc wifi i/e 10.42.0.1. You do not need to add a port number. In the box to the right of >User name type in your Linux Lite sudo user name. In the box to the right of >Password type in your password. Make sure these match the ones you entered into the original SSH connection we previously set up.
Next click on the >SSH tab. Check the box >Enable SSH tunnel. Check the box >Tunnel via loopback address. Click the radio button >Same server at port 22. In the box next to user name type in the same user as before. Click on the radio button >Password. Click the >Save button to the lower left. Now right click on your new connection and from the menu select >Connect. When prompted enter your SSH password, and your Linux Lite 3.0 remote desktop will load to your other Linux OS computer. You have now connected two Linux computers together via an SSH tunnel and accessed a remote desktop with Remmina. Disconnect from Remmina once you have assured all is working, and go on with the rest of this tutorial to set up keys for SSH.
*Setting Up And Using Keys In SSH
Now if you intend to use this connection over your Internet provider’s router and modem, you will of course need to change the IP addressing convention to DHCP scale something like i/e 192.168.0.1-254, and it is a good idea to use keys rather than passwords on your SSH client and servers. This is easier to do than you may expect, and we are going to go ahead and do it while our two computers are still connected via our ad hoc wifi connection. Before we begin we are going to increase the key bit depth of encryption on our server. Open a terminal and enter the command below on your Linux Lite 3.0 computer which is in this case the SSH server side of the connection. This step may or may not be necessary, but because we are going to generate our keys on the client which is in our case not a Linux Lite 3.0 computer, we will do it just to avoid any unforeseen complications.
sudo nano /etc/ssh/sshd_config
Hit >enter and enter your sudo password if prompted hitting >enter again. Our SSH configuration file will open. Navigate through the file to around the twentieth line and locate: ServerKeyBits: 1024 or 2048 and navigate to the end of line and backspace out the number typing in the new entry 4096. Hit >Control+x, then shift+y, then >enter, and >enter again to save changes. Now enter the command below to restart ssh.
sudo systemctl restart ssh
Now go to the computer running the other Linux OS (the client side in our case) open a terminal and enter the command below to generate our 4096 bit key pair.
ssh-keygen -t rsa -b 4096
Enter your sudo password when/if prompted and hit >enter. The keys will then generate. When prompted to create a password use the SSH password which is our Linux Lite sudo user password we have used all along, or create a new strong password of at least thirteen multiple characters and symbols, and hit >Enter again. Accept the default file paths by hitting >enter again. Next to check the permissions on the files enter the command below.
cd ~/.ssh
And at the next prompt enter the command below..
ls -l
This lists your key files, locations, and permissions. Now to load our new keys to the server we need to enter the command below. Our two computers are already connected via ad hoc wifi so this will work nicely. Enter password when prompted, and the keys will be copied to the server.
ssh-copy-id 10.42.0.1 (the IPv4 address of the Linux Lite computer where our server is located.)
Return to the terminal on your Linux Lite computer and enter the command below to open up our SSH server configuration file again.
sudo nano /etc/ssh/sshd_config
Navigate through the file to around the twenty fifth line to find the # Authentication: line. It may be already blank beyond the colon because of uploading our keys, if not just backspace it out to the colon and type in no with a space first. PermitRootLogin: on my server reads: prohibit -password. RSAAuthentication should read: yes. PubkeyAuthentication should also read: yes. Phew! Almost done. Hit control+x, then shift+y, then>enter, then >enter again to save the file. Now enter the commands below to restart our SSH server, and x11vnc.
sudo systemctl restart ssh
x11vnc -once -loop -localhost -noxdamage -repeat -rfbport 5900 -shared
Return to the terminal on the computer with the other Linux OS (our client) and enter the command below, entering password when prompted.
ssh-add -k ~/.ssh/id_rsa
Once prompted that the key for 10.42.0.2 (see previous note) is added, accept the default file path by hitting enter. When the command prompt returns, type in exit, and hit >enter to close the terminal.
Open up Remmina again, and right click on the new connection we just created, and from the menu select >Edit. Click on the >SSH tab and click on the radio button >Public key (automatic). Click the >Save button on the lower left. Now right click on the connection, and click on >connect from the drop down menu and your Linux Lite 3.0 remote desktop will reappear on your other Linux OS computer, using an SSH tunnel, and now using keys instead of passwords to connect. Remember to MINIMIZE the terminal on the server (Linux Lite) side to hide it, as closing it ends the x11vnc session, also remember to reset the previous SSH secure shell connection we set up to now use keys. SFTP in Thunar will now be instantaneous via this keyed SSH connection and ad hoc wifi.
Good luck

Greetings,
I have Power Broker Open installed on my LinuxLite machine for AD authentication. When I go into User Manager, the Groups Menu ends with the group "List". I am sure there are more after that but I can't get to them. Any suggestions?

| Linux Lite - Grub in 3.2 |

I've heard all the concerns from people about the way Linux Lite handles Grub, especially in respect to multi-booting with other operating systems.
First, let me reiterate that Linux Lite is targeted and Windows people first and foremost. I don't want people to infer from that, that I ignore or place little emphasis on other distros.
In Linux Lite 3.2 I'll default back to the way Grub handles other operating systems. I'm unsure of the outcome of this, and I'll revert back to placing Windows to the fore in 3.4 if it doesn't all work out. So in 3.2, LL should play nicely with other operating systems, time will tell. The Beta will be released in mid to late October. Linux Lite 3.2 will be released 1st November, 2016.

| Tutorial/ LL 3.0 Remote Desktop On Other Linux OS Via Remmina & x11vnc ad hoc |
|

To produce a remote version of our Linux Lite desktop on another Linux computer we are going to need to some kind of vnc server to our Linux Lite 3.0 system. In the past Ubuntu based distributions have used vino and a few others, several enabling various versions of Internet based softwares. We are going to download and install the powerful, versatile, and immensely configurable x11vnc server to our Linux Lite 3.0 computer, and use Remmina on our other Linux OS to get a fully functional Linux Lite 3.0 remote desktop. *Because we are going to use our now properly functioning ad hoc wifi to make the connection between the two computers, we are going to use a simple and powerful setup, but it’s important to remember to use an SSH tunnel if you are intending to send data over any broader easily reachable wifi public channels like your Internet access provider’s. We will cover that setup in another tutorial.
Make sure you are connected to the Internet, and on your Linux Lite 3.0 computer click >Menu>System>Install/Remove Software to open >Synaptic. Authenticate and select >All from the left menu and wait for the package inventory to update. Type >x11vnc into the search box. From the files that appear select the package >x11vnc 0.9.13-1.2build1. Make sure the file numbers are correct, because if you have added Debian8 “jessie” repositories to Synaptic as I have you may get the wrong package listed. If that is the case for you click >Settings in the top toolbar, then >Repositories, then the >Other Software tab, and uncheck the Debian8 “jessie” repositories. Close Synaptic, and then reopen it and do your search query again and the correct x11vnc package will appear. Select the > x11vnc 0.9.13-1.2build1 package and click >Apply, agree to the dependencies and x11vnc will download and install to your Linux Lite 3.0 system. Log out and reboot your system.
You will have to disconnect from the Internet for the next part of this tutorial so copy it and paste it to a Libreoffice document so you can review it as you go along.
The x11vnc GUI tool kit we used so handily in Debian 8.3+ still does not entirely work with Linux Lite 3.0, so don’t bother clicking on the x11vnc Server icon now located at >Menu>Internet on your Linux Lite 3.0 desktop. Instead open a terminal and type in the following command as the syntax is expressed here: x11vnc -once -loop -noxdamage -repeat -rfbport 5900 -shared This will start the x11vnc server. Once it has started connect to your ad hoc wifi, and MINIMIZE the running terminal. DO NOT exit or close the terminal window as this will shut down the x11vnc server in Linux Lite 3.0. If you do accidentally close the terminal, simply re-open it and enter the above command again.
The first link below provides an exhaustive list of current commands for x11vnc, and the second link contains Ubuntu documentation for using several different vnc servers, including x11vnc.
http://www.karlrunge.com/x11vnc/x11vnc_opts.html
https://help.ubuntu.com/community/VNC/Servers
Now go to the computer running the other Linux system you want to have your Linux Lite 3.0 remote desktop load to. Open Remmina. Click >Connection in the upper left window menu, then >New and the window entitled Remote Desktop Preferences will open. In the box to the right of >Name type your Linux Lite computer’s netBIOS name. (everything between @ and the colon: that appears in your command line in the terminal when you open it) Now in the box to the right of >Group type simply / a forward slash. Now in from the drop down menu in the box to the right of >Protocol select >VNC – Virtual Network Computing. Next in the box to the right of >Server type i/e 10.42.0.1:5900 (which should be whatever the IPv4 address of your Linux Lite 3.0 computer is on your ad hoc wifi network, plus the listening port definition of 5900. Leave the box to the right of >Repeater blank. In the box to the right of >User name type in your sudo Linux Lite user name. In the box to the right of >Password type in your Linux Lite sudo password. In the box to the right of >Color depth type click the drop down menu and try >High color 16bit first. You can experiment with color settings later on. With ad hoc wifi you shouldn’t need to worry about bandwidth so most of the better options will be available to you to experiment with later. In the box to the right of >Quality click the drop down menu and select >Poor (fastest). Again you can experiment with these settings after our first successful connection. Click next on the >SSH tab and make sure the box next to >Enable SSH tunnel is unchecked. Click the >Save button to save your connection.
Now click on and connect to the ad hoc wifi we enabled previously and connect the two computers together via ad hoc wifi. Select and right click on your now listed new connection in the Remmina Remote Desktop Client window and from the >menu click connect. Your new Linux Lite 3.0 remote desktop should appear almost instantly on the desktop of your computer running the other Linux system.
*Read This Note: You will notice if you are close enough that with our current settings the mouse movement occurs on the remote desktop and your Linux Lite desktop, and applications open and close at the same time as well. This is typical for Linux to Linux remote desktop connections, but it can be configured away with x11vnc commands and Remmina selections depending on the computers involved, the Linux distro involved, and the peripheral hardware involved. The basic setup we used here is just a beginning, but one that works most of the time, and obtains the unique security of an ad hoc connection.

Hi guys Im pretty new to thhis distro and I fell in love with it after a month.
Im not an experienced linux user and I learnt hard way why dd is refereed to as "disk destroyer'.....
My issue started,when I tried dd-ing an iso on ll3 and instead of sdb i set it to sda.
After hours of fails I managed to boot Lubuntu from my android and installed it.
Now every time I try to install LL3 I get the following message on starting live session from usb(and phone):
(initframs) mount: mounting /dev/loop1 (cdrom/casper/filesystem.squashfs) on //filesystem.squashfs failed: no usch device
After that If I type exit in busybox it will continue to setup and end up in kernel panic and just freeze.
Things I tried:
1.Re-downloading iso's and checking md5sum (always the same md5)
2.Formating the usb to fat/fat32 and using Unetbootin (fails on initframs)
3.Trying to boot from Android (drivedroid app) (fails on initframs)
4.Disconnecting everything except ethernet,keyboard and usb (fails on initframs)
5.dd-ing it to usb (fails on initframs)
6.Trying 32bit (fails on initframs)
7.Changing usb's (fails on initframs)
8.Trying 2.8 (fails on initframs)
9. Using recommended gtk usb maker on both lite 3.0 and 2.8 (fails on initframs)
I had no issues before launching live session from usb,but since I dd my whole HDD I cant (Had to create all new partition table and whip it clean) .
I read that this usually happens when md5 is off,when usb is out of mem,when there isnt enough ram.... but everything is fine (I have a gig of ram,8gb usb,md5 is consistent...).
I managed even to live boot Kubuntu,but not Lite.....
Id really like if someone could help me out as this is by far the best "legacy" distro and I got used to it very much (kernel is a beauty)!
