Clients should auto-detect their graphics hardware and load the appropriate drivers. Yours seem to not be doing that. Perhaps you have an outdated version of Edubuntu (or a too-new version that has bugs). Or maybe you're just unlucky. Either way, you can manually specify the drivers and resolution in lts.conf. I think Edubuntu keeps that file in /var/lib/tftpboot, but I'm not sure. I also think you need to run another command after editing lts.conf (this is related to Edubuntu using a squashed image instead of NFS, like my Debian system). Somebody on this list is sure to know what that command is -- I can't remember it. Anyway, you'll want to run 'man lts.conf' to get some details on how that file is structured. You'll probably want to include something like this for your problem clients: XSERVER = vesa X_MODE_0= 1280x1024 vesa is a good xserver value to start with, because it usually works. It is slower than others, so once you get things working you may want to try other values.

Re: [Ltsp-discuss] Upgrading LTSP...
On Wed, Sep 07, 2011 at 02:38:47AM -0700, Michael C. Robinson wrote: The idea behind LTSP is to support thin clients and unfortunately, redundancy is extremely hard to implement because the expectations aren't compatible. There is no standard way to pick one server over another during a network boot that I know of. Another issue, what specifically does one go the next version of LTSP for? What is lacking in the current version that you need from the next version? Sometimes, it is better to patch an older version that works than it is to move to a newer version with new bugs. One option, you need a host OS on the server that doesn't run LTSP and an emulated Linux environment(s) that does. This is a possible way to fire up one server or the other so that the server you want is the one you are running. Problem is, how do you test the new server while you let your clients use the old? The immediate appeal of running LTSP on the server under emulation is that you don't have to reboot. The downside, well you have to have a hefty enough computer and you have to understand emulation on top of understanding LTSP. If you can emulate a subnet or if you can run a second subnet and a test client on that secondary subnet... You should be able to emulate both LTSPs as long as one runs on one subnet and the other runs on another subnet. DHCP could be a problem though if you give out random IP addresses. Maybe on the secondary subnet you can do static configuration??? So I'm saying do static configuration on your test subnet and dynamic configuration on your production subnet. Looks like this can work. BTW: If you have two physical subnets and you partition the servers between them, both can be dynamically configured. Network cards are pretty cheap these days and memory/hard disk space/processing power is getting pretty cheap too. Only when you share media for two different IP subnets does dhcp become problematic. Are you trying to test out only a new version of LTSP, or a new Linux Distro? If just LTSP, you can create your chroot with the --base parameter and specify something other than /opt/ltsp. What I do is create several chroots, such as /opt/ltsp.squeeze, /opt/ltsp.wheezy, opt/ltsp.20110907, etc. Then I symlink /opt/ltsp to one of them. Changing the symlink changes which chroot I use. (I think I have to restart the nfs server to make this work, but it's been a while...) If you need to test different base distros, you can use virtualization. You don't need different subnets. Just specify in dhcpd.conf that certain mac addresses get certain ltsp servers. Create different pools in dhcpd.conf and specify a next-server and/or root-pathin each of them. This lets you specify where the thin clients get their tftpboot files and their nfs root files.

Get this error message in /var/log/syslog: LTSP5 uses LDM instead of traditional login managers (like GDM, slim, etc.) In lts.conf, you can set: SCREEN_07 = startx (I think this is still supported) This may let you use slim. By default, SCREEN_07 is probably set like: SCREEN_07 = LDM Note that for startx to work, you need to have XDMCP enabled on the server. I'm not sure how to do that in slim, if it is even supported at all. If it does work, I don't think you need to mess with the keys at all, as XDMCP sends everything over the network unencrypted. But maybe somebody else on the list has more knowledge about this. Note that you can lighten things up a little bit, while still using LDM, by specifying in lts.conf: LDM_DIRECTX = true This eliminates encryption of server-client traffic, which could possibly earn you the same performance gain you are hoping to obtain by using slim. -Rob -- Simplify data backup and recovery for your virtual environment with vRanger.

Ubuntu moves at a rapid pace, so that could be the reason. If you go w/ Ubuntu, I'd recommend sticking with an LTS version. If you go with Debian, stick with stable and optionally use the later LTSP packages from the backports repository. This will reduce the number of major upgrades you need to deal with. Fedora has an LTSP list of its own. k12...@redhat.com. Traffic on that list is kind of light, but they may be better-suited to answering Fedora-specific questions.

With Lucid LTS having had a while to settle and the impending 'death' of KDE3.5 and Hardy, I thought I'd get up a spare server and start testing the latest and greatest LTSP and Kubuntu in advance of moving our systems over to it so that's what I've spent the last couple of days doing and it's all become something of a nightmare :-( Sticking with LTSP 4.2 for the moment.. (it's faster to boot than LTSP5 although I do like 5's idea and design); If I boot my thin clients without glx modules in Xorg (ie with the the vesa driver) then the desktop performance is truly dire and becomes unusable. If I boot them with the (Xorg detected) Via drivers and glx then Kde crashes out just after showing the initial desktop and panel. The .xsession-errors file is some 38K long! but the point of failure seems to be kdeinit4: Fatal IO error: client killed. I've started off with kubuntu-10.04-alternate-i386.iso and upgraded via apt to the latest versions of everything; I've even added the kubuntu-ppa and installed KDE 4.4.5 but there's no difference. FWIW, using a Gnome session on the same server and thin-client works fine as does Xfce4 (although with glx, compositing turned on and shadows and transparency it's not a snappy as without but proves the point that Xorg/glx in itself isn't the problem) so I don't think it's the thin-client(s) or LTSP that's the problem but something in KDE4/plasma/etc; I'm just asking here in the hope that others have been down the same path and found a solution. So. am I flogging a dead horse trying to use KDE4 on modest hardware? Has anyone else got a similar setup working? Any suggestions on where to go from here? Perhaps KDE4 is just too heavy on the graphics for any non-local X display... but I hope someone will tell me otherwise. Oh using LTSP5; Xorg dies (using SCREEN_07 = xdmcp) as soon as it tries starting the KDE4 session :-( but works fine with Gnome. I have very little experience with KDE4. I have tried it briefly in a virtual machine running Debian Squeeze, and it seems reasonably quick. (To be fair, I only opened a handful of applications, but it wasn't laggy). So I'd recommend you give Debian Squeeze a try, just to see if its performance is any different than Kubuntu. In general I find that Debian is a little more old hardware friendly than Ubuntu. Alternatively, you could try another KDE-like desktop. You can make Gnome have a KDE-like menu at the bottom of the screen. Alternatively you could try LXDE (very lightweight), FVWM-Crystal, IceWM, or one of the many others out there. Personally I'd recommend giving LXDE a try. Or you could try to fix the problems you're having with Kubuntu, but I don't have any advice for you there. Maybe somebody else can help with that. -Rob -- This SF.net email is sponsored by Sprint What will you do first with EVO, the first 4G phone?

We are looking into the future and like what we see so far. I have been dabbling in similar setups since late 1999 to early 2000 so I have some basics. but so much has changed now. Here is what we would like to see happen in the testbed: Run Ubuntu on a server with LTSP installed have a windows machine (xp, vista, 7, or a combination of them) to serve windows programs to the clients have about 3-5 client machines to test with. This is planned to be done in a closed testbed off our main network. I have a few questions though 1. What version of Ubuntu should I look at? I would like to test 10.04 but I have read here on the list where people are having issues with it. Many people, myself included, recommend not adopting a new Ubuntu version until it's been out for a month or so. The release cycle is so fast that new releases aren't always as rock-solid as they could be. Of course, if you're just testing the waters this might be ok with you. But if things don't work well, don't get discouraged -- just try a different release. 2. Would I need the server to be i386 or amd64 install? I have read that all clients need to be 32bit anyways but the server may have more memory than 32-bit can read You can run a 64-bit server with 32-bit clients. You need to build the chroot with the --arch i386 option. 3. What is the best way to tie windows programs into the ltsp server? I am thinking I may need to use the ltsp-cluster instead of the standalone. You could try to run the windows programs on the LTSP server, using wine. Sometimes this works. The most foolproof way to do what you want, though, is to run a Windows terminal server and let your LTSP clients connect to that. 4. As long as a client can network boot I should be able to use it to test, correct? We don't have any thin clients currently, but I can remove the hard drives from a few pc's and test with them. You don't need to remove the hard drives. Just change the boot order to boot from the network first (or boot from a gpxe cd, if you can't PXE boot natively). -Rob -- _ Ltsp-discuss mailing list.

Re: [Ltsp-discuss] Firefox is indeed the high disk IO culprit was Re: recommend a disk setup for LTSP install?
If the problem is Firefox making too many writes to the users' cache files, as some people have speculated/demonstrated, then this isn't an LTSP-specific problem. It should affect any system that has many simultaneous users accessing /home, such as NFS-mounted home. I imagine that's pretty common, so I'm surprised that this isn't a more widely-complained-about problem. -Rob On Thu, Apr 01, 2010 at 05:25:04PM -0700, Jordan Erickson wrote: Ahh, the good ole days of Firefox tackling an LTSP network like a football player would to an elderly woman carrying groceries home from the market. ;) Try these out, they helped me a bunch: https://help.ubuntu.com/community/UbuntuLTSP/Firefox3Optimize http://lns.wikidot.com/nsprupdate Cheers, Jordan john wrote: Hi all, As a follow up to my previous post.

You could try creating a script /usr/local/bin/mydesktop.sh containing the command /usr/bin/icewm /usr/bin/idesk and then tell nxclient to run that.

In my earlier post, I had not yet configured Ekiga to register two accounts simultaneously. (I almost feel like I'm budding into a private conversation at this point.) There still appears to be a fundamental difference here, in that Scott is running multiple SIP clients on multiple machines--no port-binding conflict there. Actually, David, I am running 7 SIP Clients across 3 Dynamic IP addresses, so the port binding issues remain the same - how to handle multiple LAN requests, from the same IP, for port 5060. I mentioned that I have a 4 Line Linksys phone in this setup - that's 1 IP Address and 4 SIP clients. I also mentioned that one instance of Ekiga has two SIP accounts registered - that's 2 SIP clients to 1 IP address. Without using SIP ports for each client beginning at 5061 and incrementing by one, per device, then I have to use a proxy like siproxd for the multiple LAN requests for port 5060. Actually, I have managed to get multiple Ekiga instances on my LAN to work. I used avahi for this, per the advice of somebody on this list. Although I only tested communication within the LAN. I did not test simultaneous internet-based calls. I've also had multiple Ekiga accounts registered on a single client. My last problem (hopefully my last) is that multiple Ekiga clients on the same machine refuse to load without giving me errors about the port. I've only been able to fix this by manually changing the ports in each Ekiga config. Is there any fancy iptable rule or other script that can say oh, you want port 5060, well that one's taken so I'll give you 5061 instead and forward all your traffic there? If not, then I'm back to changing ports manually and hoping the Ekiga devs implement the above feature. -Rob -- This SF.Net email is sponsored by the Verizon Developer Community Take advantage of Verizon's best-in-class app development support A streamlined, 14 day to market process makes app distribution fast and easy Join now and get one step closer to millions of Verizon customers http://p.sf.net/sfu/verizon-dev2dev _ Ltsp-discuss mailing list.

I've also had multiple Ekiga accounts registered on a single client. Right, but the point that I'm trying to make is that there is a fundamental difference between multiple accounts in Ekiga, and multiple instances of Ekiga on a machine. When you attempt to run multiple instances of Ekiga on a single machine (this includes the standard LTSP scenario), they are not aware of each other, except to notice that their port is not available. In the latter scenario, Ekiga is aware of these multiple SIP accounts and can manage them and their ports. Similarly, there is a fundamental difference between multiple instances of Ekiga on a LAN, and multiple instances on a machine, because whoever is doing NAT can recognize multiple IP addresses using the same port and manage that with port rewriting. Where port rewriting is not an option, a SIP proxy, such as siproxd can help with this by managing the LAN ports pre-NAT. The easiest way I can see to manage this is to try running Ekiga as a local app. Hopefully this will change the nature of the problem from being multiple instances of Ekiga on a single host, to multiple instances of Ekiga on a single LAN, which should be fundamentally different as summarized above. Failing that, you may have to manually manage your SIP ports. I agree with you. I'll have to look into local apps. I'm pretty sure my version of LTSP 5 doesn't support that, but I seem to remember later versions of LTSP 5 being backported to Debian Lenny. -Rob -- This SF.Net email is sponsored by the Verizon Developer Community Take advantage of Verizon's best-in-class app development support A streamlined, 14 day to market process makes app distribution fast and easy Join now and get one step closer to millions of Verizon customers http://p.sf.net/sfu/verizon-dev2dev _ Ltsp-discuss mailing list.

[Ltsp-discuss] multiple Ekiga instances on one server
When I try to register multiple Ekiga accounts on the same server (different users, different thin clients, but it's all running on the server), I get errors: Error while starting the listener for the H.323 protocol and Error while starting the listener for the SIP protocol It seems that each instance of Ekiga is attempting the use the same ports for SIP and H.323. This makes sense, but is there any way around it? If not then my LTSP server can only run a single instance of Ekiga. -Rob -- This SF.Net email is sponsored by the Verizon Developer Community Take advantage of Verizon's best-in-class app development support A streamlined, 14 day to market process makes app distribution fast and easy Join now and get one step closer to millions of Verizon customers http://p.sf.net/sfu/verizon-dev2dev _ Ltsp-discuss mailing list.

PXEbooting should be all you need to do. Fedora does something different w/ the networking than Ubuntu and Debian. If I recall correctly, they set up a bridged virtual network device for the thin clients to connect to. I don't know the details of it, but maybe that is what's causing your problem. Perhaps the TFTP server and/or other services are not listening on the correct network device. -Rob -- This SF.Net email is sponsored by the Verizon Developer Community Take advantage of Verizon's best-in-class app development support A streamlined, 14 day to market process makes app distribution fast and easy Join now and get one step closer to millions of Verizon customers http://p.sf.net/sfu/verizon-dev2dev _ Ltsp-discuss mailing list.

Re: [Ltsp-discuss] Locking terminal screens after idle
There are settings for this in your screensaver program. Two common ones are gnome-screensaver and Xscreensaver. Gnome-screensaver uses gconf to make these settings. Root user can make gconf settings default and/or mandatory for users. Xscreensaver uses regular text files for these settings. Each user can have a .xscreensaver file in their $HOME directory. The setting you want, I believe, is this: lockTimeout:0:15:00 You can create a .xscreensaver file and put it in /etc/skel so all new users will be given it. Note that users will be able to change their own .xscreensaver files unless you change the permissions on them to disallow write access. -Rob On Mon, Jul 20, 2009 at 08:08:51AM -0400, Ryan Stepalavich wrote: Good morning, I'm running LTSP 4.2 on RHEL 4 using IceWM.

One option is to download the video and watch it with the standalone player, but there's a cooler way: Install the greasemonkey extension for firefox/iceweasel, and then install the HQTube script. http://userscripts.org/scripts/show/24999 I tried it and it works nicely. On my system, the videos are shown with the totem plugin. I'm not sure how to specify to use mplayer instead, so I uninstalled totem temporarily and the mplayer plugin took over. Both plugins worked well, with less cpu usage than Adobe's flash player. I tried this on an LTSP thin client, and on a standalone machine. The standalone machine was a P3 700MHz laptop that would not play a youtube video with the flash plugin. It played using the mplayer plugin just fine, at about 40% cpu usage. Anyway, I'm gonna experiment some more with it. I figured some folks on this list might be interested, considering that I periodically hear complaints about flash audio not working on thin clients. -Rob -- Enter the BlackBerry Developer Challenge This is your chance to win up to $100,000 in prizes!
