how can i use xinerama on a client (debian) ? can it be done anyway ?
driver = mga
yanu: did you install xinerama in the chroot?
|07:08||alkisg has joined #ltsp|
ftherese: probably not, buzzy installing
how much experience do you have with ltsp?
yanu: have you ever installed something in the chroot before?
ftherese: ya sudo chroot /opt/ltsp/i386/ apt-get install ...
i suppose i have to enable xinerama in the config? in lts.conf of /etc/X11/xorg.conf
do you have DIRECTX enabled?
explain DIRECTX ? isn't that windowsstuff?
|07:25||otavio_ has joined #ltsp|
ach ok, now i get that directx, no via ldm
that is probably unimportant I am thinking now
|07:28||alkisg has quit IRC|
when you say "using xinerama" what do you mean exactly?
it installs but then what kind of error/problem are you having?
in the client, there is a matrox dualhead-agp-card PCI:1:0:0
i connected 2 monitors, they al more-or-less the same
so now i want to enable xinerama, so ik have one wide screen
there is no error, just on the 2 monitors, i see the same
the same session, move with the cursor -> same move on the 2 monitors
so , it is the script that doesn't recognize the variables in lts.conf X_XINERAMA = Y

have you checked that there isn't some little extra program that has to be installed in the chroot for it to work?
xorg-mdg is installed, i checked 'apt-cache search xinerama' ...
I unfortunately don't think I can be of much help... I haven't tried to use that feature...
are you using the ubuntu dist?
i did it once with ltsp4.2, a long long time ago
|07:41||alkisg has joined #ltsp|
hmmm... yeah... I really don't think I'd be much help unless the problem had to do with printing or simpler stuff
google isn't that helpfull ...
i doubt that it is even possible

i've got access to my switch finally ...
i never thought connecting the dots would be so hard
anywho, so it appears there is flow control option, but it appears to be turned off
Did you have to change your ip to "see" the switch?
however, there is "auto sense" and it is sensing 100. if i try to change it to 1000 it drops the connection.
no, i changed the address of the server
Yup that's what I meant
then accessed it, and changed the server ip back
So the server connects at 100mbps, not gigabit?
i did have a question about the server ip. the server is serving dhcp to all the clients. i assume that the dhcpd deamon has a range of ip address it uses set somewhere, or does it start with the address of the server for it's subnet
no, the server connects at 1000
but any client i plug in is 100
Well, your clients have 100 mbps cards, right?
So it's only natural that they connect at 100...
so if flow control is off, what else am i missing?
Can you do a test bench?
I.e. get some time when 10 clients are not in use, and try iperf on them
(from a *local* terminal, not from a gnome-terminal)
|15:59||japerry has joined #ltsp|
When I tried it with 10 of my 100-mbps clients, I saw that the server actually sent data very close to 1 Gbps
i have only 5 clients right now. 4 working
but i can boot those up and try that
It should be enough
You should be able to see something close to 400 mbps
btw, ethtool -a eth1
If you only see 100, then there's still a problem
Pause parameters for eth1:
the switch did not have flow control on.
That doesn't sound like your switch supports flow control :)
well, it has a turn on/off option
and it was off by default
Ahmuck_Sr: what nic is that? intel?
i do have que mode, and "strict" or "wrr"
alkisg: let me check
I've never seen a switch web interface, can't help you with that...
01:0a.0 Ethernet controller: Marvell Technology Group Ltd. 88E8001 Gigabit Ethernet Controller (rev 13)
Hmmm it doesn't seem realtek based... can you try to change flow control from the server?
strict services in sequential order, transmitting all higher priorty before lower priorty
wwr, is weighted, scheduling wiethgs for ques 1.4
Ahmuck_Sr: maybe that's some kind of controls, but not *flow* control
(i.e. it doesn't have anything to do with pause signals)
Ahmuck_Sr: try this on the server - it may cut your connection momentarily: sudo ethtool -A eth0 autoneg off rx off tx off
02:00.0 VGA compatible controller: nVidia Corporation NV43 [GeForce 6600] (rev a2)
i have two nics
they are both gigabyte nics
Well, the one facing the clients...
isn't that eth1?
ooops, so: sudo ethtool -A eth1 autoneg off rx off tx off
...and then to see if it had any effect: sudo ethtool -a
forgot to hook up the clients again
The clients don't need to be turned on to run ethtool on the server...
i thought you wanted me to start the clients?
I don't think you disabled flow control from the switch, so, better do that from the server...
...so I was telling you to do this: https://help.ubuntu.com/community/UbuntuLTSP/FlowControl#Disabling%20flow%20control%20with%20ethtool
yes, i'm looking at that doc
i double checked, flow control is turned off
now i have a bigger problem, for some reason my client's aren't booting
|16:11||cyberorg has quit IRC|
my clients are not connecting and getting an address. where is the dhcp address range set? i'm wondering if i changed the client side nic to the wrong ip address
cat /etc/network/interfaces - for the address, and cat /etc/ltsp/dhcpd.conf - for the ranges
...and sudo invoke-rc.d dhcp3-server restart
ouch, i'm learning something
my brain hurts
|16:20||* alkisg is (unsuccesfully) trying to set up a dns server.. :(|
|16:20||japerry has quit IRC|
oh, that's easy
anywho, looks like dhcp was stopped for some reason
Really??!!! After `sudo apt-get install bind9` I can't declare zones, or do nsupdates... /me has a lot to learn about dns
i never went that far
k, thin clients are started
What, for the benchmark? You need to install iperf or netperf on the chroot, first...
sudo ethtool -A eth1 autoneg off rx off tx off - samo thing
Ahmuck_Sr: ok, let's do this step by step
ok. ... sudo aptitude install chroot netperf
1) Install iperf on the chroot and then run ltsp-update-image
let me google for ltsp chroot installtion
sudo chroot /opts/ltsp/i386 apt-get install iperf
*and if it fails you need to mount /proc...

yeah !! I finally have a working shutdown and reboot that doesn't break the application server (close the session cleanly)
stgraber: i saw you added the hook, but i didn't see what part of the code actually made use of the hook
vagrantc: that's part of the Ubuntu packaging
vagrantc: as it's gnome specific (calls gnome-session-save) and uses icons that aren't there on some distro
basically, that's two .desktop files writting shutdown or reboot in /tmp/ldm-logout-action using ltsp-localapps, then calling a session logout
on logout ldm will read that file and do the action in it. That way I was able to remove our previous hack (sudo rights to shutdown) and have something that won't break the user session (opened files and stuff like that)
anyone can write to /tmp/ldm-logout-action ...
my current goal is to have something rock solid by Friday, then upload a final ldm and ltsp in karmic
vagrantc: well, that's on the thin client, so it can only write by a call to ltsp-localapps
vagrantc: and AFAIK multiple ldm session doesn't work so well, so it's usually a single user who's in front of the thin client that will do it
