Sorry Seems LDM doesn’t want to use LXDE by default (despite the fact that it is the only DE installed), so you have to add this to lts.conf: LDM_SESSION=LXDE You can find available DEs in the "/opt/ltsp/i386/usr/share/xsessions" directory. P.S. LTSP-clients in Ubuntu 16.04 remove sshd service on boot for some reason so if you want to be able to connect to clients via SSH you need to add this to lts.conf: KEEP_SYSTEM_SERVICES="ssh" Regards, Vladimir.

Re: [Ltsp-discuss] No home directory
Users in the LTSP-environment are authenticated on the server and their home
directories are mounted from the server. You don't need to create home
directories in the chroot.
ltsp-update-image removes everything from /home directory by default. The list
of files removed from the image is stored in the
"/etc/ltsp/ltsp-update-image.excludes" file on the server.
>> The client gets to the log-in screen, but the GUI can't get past that
Did you create the user on the server? What do syslog and auth.log say?

Vladimir

Subject: [Ltsp-discuss] No home directory
It's been a while since I last had to install LTSP, and I've never done it
using Ubuntu 16.04 before, but things are going very wrong here and I hope
someone can help.
I've installed Ubuntu 16.04 and LTSP but the clients don't have home
directories. I have a machine assigned to opac30 in dhcp.conf:
host opac30 {
# info desk PC
hardware ethernet 00:0f:fe:33:8d:b9;
fixed-address 10.0.123.130;
filename "/ltsp/i386/pxelinux.0";
option host-name opac30;
}
In lts.conf:
[00:0f:fe:33:8d:b9]
# info desk PC
LDM_USERNAME=opac30
in the chroot I have a home directory:
/opt/ltsp/i386/home/opac30/
total 24
drwxr-xr-x 3 opac30 opac30 4096 May 16 09:22 .
drwxr-xr-x 32 root root 4096 May 16 09:22 ..
-rw-r--r-- 1 opac30 opac30 220 Aug 31 2015 .bash_logout
-rw-r--r-- 1 opac30 opac30 3771 Aug 31 2015 .bashrc
drwxr-xr-x 3 opac30 opac30 4096 May 16 09:21 .config
-rw-r--r-- 1 opac30 opac30 655 Jun 24 2016 .profile
I created the image with ltsp-update-image i386
The client gets to the log-in screen, but the GUI can't get past that. If I
ctrl-alt-f1 I can log in, but there is no home directory. /home/ is empty.
Doesn't `ltsp-update-image i386` build an image using /opt/ltsp/i386/ ?

You could try installing minimum version of Ubuntu, mount devices from the host: mount --bind /proc /opt/ltsp/i386/proc mount --bind /sys /opt/ltsp/i386/sys mount --bind /dev /opt/ltsp/i386/dev mount --bind /dev/pts /opt/ltsp/i386/dev/pts chroot with: LTSP_HANDLE_DAEMONS=false chroot /opt/ltsp/i386 and install required packages.

Re: [Ltsp-discuss] Ubuntu 14.04 pnp with freerdp
You need neither Windows Ultimate nor Hyper-V to enable RemoteFX. Windows Server 2012 natively supports RemoteFX, you need only to set 32-bit color mode on your server in Group Policy.

[Ltsp-discuss] Can't set up Ubuntu 16.04 LTSP with NFS
Hello, I'm trying to configure LTSP to use NFS on Ubuntu 16.04 (it uses NBD by default). First, I added to /etc/exports: ## /opt/ltsp/i386_xenial *(ro,no_root_squash,async,no_subtree_check) ## Then I created PXE config file /var/lib/tftpboot/ltsp/i386_xenial/pxelinux.cfg/default: ## default ltsp-NFS ontimeout ltsp-NFS label ltsp-NFS menu label LTSP, using NFS kernel vmlinuz append ro initrd=initrd.img init=/sbin/init-ltsp forcepae root=/dev/nfs ip=dhcp boot=nfs rootpath=/opt/ltsp/i386_xenial ipappend 2 ## The client succesfully booted but I couldn't log in. After some search I discovered that all system files are not writeable by root though they have 644 permissions. However, they can be made writeable with chmod: ## root@vma-test:~# ls -l /etc/environment -rw-r--r-- 1 root root 96 окт 3 14:07 /etc/environment root@vma-test:~# echo '#test' >> /etc/environment -bash: /etc/environment: Permission denied root@vma-test:~# chmod 644 /etc/environment root@vma-test:~# ls -l /etc/environment -rw-r--r-- 1 root root 96 окт 3 14:07 /etc/environment root@vma-test:~# echo '#test' >> /etc/environment root@vma-test:~# cat /etc/environment PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/game s:/usr/local/games" #test root@vma-test:~# ## NBD works ok so I guess there's something wrong with my NFS configarion.
