| RickZilla | Hi gang, on this page http://www.edubuntu.org/GettingStarted I see the line "Besides the standard software available on the Edubuntu CD, you will also find a world of software in the Edubuntu Universe, an on-line repository containing more than 10GB of community contributed software." But I don't see a link to it anywhere. Can somebody point me in the right direction? | 16:46 |
|---|---|---|
| ogra | click on add/remove software in your menu :) | 16:50 |
| RickZilla | But surely that doesn't include all of the "10G of community contributed software", does it? | 16:50 |
| ogra | look at the top, you have a pulldown menu there .... beyond that you can use System->administration->Synaptic package manager to get the rest that not registered in add/remove | 16:53 |
| RickZilla | ogra: Thanks, I'll check that out...sounds like Synaptic goes out on the web and finds additional software for me | 17:16 |
| ogra | add/remove does as well | 17:17 |
| ogra | they are both similar apps but add/remove only shows everything that has a menu entry | 17:18 |

| jc2it | I am looking for information on how LDM is configured | 22:38 |
| ogra | through lts.conf | 22:40 |
| jc2it | Where is the documentaion located? | 22:43 |
| jc2it | for lts.conf | 22:43 |
| ogra | in /opt/ltsp/i386/usr/share/doc/ltsp-client-core/examples | 22:45 |
| jc2it | what does SCREEN_01=ldm do in conjunction with SCREEN_02=shell? | 22:51 |
| ogra | SCREEN_01 is always ignored, its used by upstart as console | 22:52 |
| ogra | SCREEN_02=shell and SCREEN_07=ldm would be better | 22:52 |
| ogra | that means there is an open login shell on tty2 and ldm on tty7 running | 22:53 |
| ogra | (thats ltsp config, not ldm specific) | 22:53 |
| jc2it | Is SCREEN_07 set that way as default? | 22:53 |
| ogra | SCREEN_XX isnt set by default, but ldm usually runs on tty7, yes | 22:54 |
| jc2it | How do I know if LDM is running? | 22:54 |
| ogra | the SCREEN variables are used to override these defaults | 22:54 |
| ogra | if ldm is running you have a graphical login screen | 22:54 |
| jc2it | How do i determine the Screen that loads as default? | 22:54 |
| ogra | thats all ldm does | 22:54 |
| jc2it | so that SCREEN_07=ldm is the first screen the user sees | 22:55 |
| ogra | ldm start on tty7 be default, thats how its implemented | 22:55 |
| jc2it | ok | 22:55 |
| ogra | right, ldm on tty7 | 22:55 |
| jc2it | great that is what I wanted to see. Now the thin client boots to an LDM screen on tty7 and by using Ctrl+Alt+F2 I can get a LTSP login to check/troubleshoot local stuff. Alos the PS -ale command verifies LDM is working. | 23:01 |
| ogra | good | 23:03 |
| jc2it | So why Can't I change the Screensaver in Ubuntu + LTSP 5? When I attempt it the Thin Client logs out the user and returns to a login screen | 23:03 |
| ogra | sounds like a bug | 23:04 |
| jc2it | Also I cannot change the Screen Effects | 23:04 |
| ogra | thats a matter of the grphics card ... usual thin clients dont have the HW to support 3D effects | 23:05 |
| jc2it | in System --> Preferences --> Appearence --> Visual effects | 23:05 |
| jc2it | hmmm How do i find out | 23:05 |
| jc2it | Do these effects then run on the thin client HW instead of the Server HW | 23:07 |
| ogra | indeed | 23:07 |
| ogra | they make use of the GL engine of your graphics card | 23:07 |
| jc2it | How do I know if something ( OpenOffice, LDM) is running on the Thin Client or the Server? | 23:07 |
| ogra | so the card needs to be set up to support 3D (out of the box only intel cards do that, since intel is the only company providing free 3D capable drivers) | 23:08 |
| ogra | all apps run on the server | 23:08 |
| ogra | only ldm runs on the client | 23:08 |
| jc2it | So the visual effects because they run through LDM are ran on the client? | 23:09 |
| ogra | they run through X | 23:09 |
| jc2it | which is on the client | 23:09 |
| ogra | right, the driver that drives the hardware sits on the client | 23:10 |
| ogra | it gets the drawing commands via network from the server | 23:10 |
| ogra | but to actually draw stuff the driver is used to drive the hardware | 23:11 |
| ogra | so that part runs locally on the client ... while the app generating the commands runs on the server | 23:11 |
| jc2it | Ok. So in my old server- thin client setup. I was running RH EL4 on the server. It used XDMCP to communicate between Thin Client and Server. the Thin clients booted into NeoLinux (Neoware's distro) and used GDM on the server to implement XDMCP. I am pretty sure I was able to run like Open GL Screensavers and such on the Thin clients | 23:13 |
| ogra | well, the crasher is surely a bug | 23:13 |
| ogra | the effects require a card and driver that supports the composite extension | 23:13 |
| jc2it | Where does LTSP generate logs | 23:13 |
| ogra | for X it uses /var/log/Xorg.6.log | 23:14 |
| ogra | and for ldm the ldm.log in the same folder | 23:14 |
| ogra | beyond that it forwards to the servers syslog | 23:14 |
| jc2it | on the server or client | 23:14 |
| ogra | the first two on the client, the latter on the server | 23:15 |
| jc2it | so to enable effects I need to find out if my card supports the composite extension and I need a driver that allows this to work. If i was able to successfully determine both then where would I change the driver that loads. I am assuming it would be in the image area for LTSP but is this located in the chroot environment somewhere? under /opt/ltsp/i386/????? | 23:50 |
