locking on a netbook

[roland-38]

Hello,

I have a netbook Samsung N110
Freenx and nx are installed on a CentOS 5 server
The client Windows xp, nomachine version 3.3.0-6

Every 5 or 10 min the connection locks up and I have to do  
Ctrl+Alt+Shift+Esc to close the nx client and restart.

Has anyone this experience?

Thanks for help

Roland

If the connection doesn't complete, then you may find the session
suspends after a few minutes.

If there is another half completed session it is possible to see
other sessions not connecting for that user.

If the network is droppping packets then the session can time out
and suspend.

etc etc etc

You don't tell us very much about what is happening.

Is the session suspended ??

Does the client work with other servers??

Do other clients work with this server ??

How many sessions are running for that user on the server??

Does it still happen if you try a different user ??

etc etc etc

I am the only one that is connected to that server (Compaq-HP ML350 6GB  
RAM)
When I work locally, nomachine will start from an acer travelmate 3000  
centrino processor. In this case there are no problems, except that work  
is done on a 21 inch Display, (Nomachine full screen) and experienced as  
slower than Vnc.

When I work remote, nomachine starts from a netbook Samsung Atom processor

In the latter case, there is no problem with login. It happens, as I  
mentioned before, after some little on-line time, few minutes, sometimes,  
exceptionally, much longer.
Remote I work via a DSL-stick (HSPDA) or from a Wifi, depending upon where  
I am, i.o.w. everywhere in Belgium, Germany or France.

I hope this is enough info.

Thanks for replying

Roland

I forgot to write below, that after this little time, the session is not  
disconnected, but only input-locked.
But I have the impression that, even after locking, some keystrokes are  
accepted. p.e. when I do Ctrl-Alt-T, nothing happens.
When coming back, after Ctrl-Alt-shift-Esc, the session showes the message  
that Ctrl-Alt-T should show, i.e. the option cancel session.

Server works, FreeNX works, account works. Good

VNC doesn't have to have the time lag for compression so on a fast LAN with
no latency issues . . .

Should work, though xp is now so slow, memory hungry and bloated that it
probably won't go as well as Linux on a netbook.

Anyone would think M$ wanted to push us onto Vista or W7.

The timeout due to not completeing takes about 3-4 mins AFAIK.

If it reaches 10 mins then it's probably something else.

HSPDA sticks often end up working a lot slower then you would hope, not always
due to 3G issues, but the IP net behind them.

Its worth keeping an  eye on what speeds you are getting. One week it can
be OK another week it seems OK browsing, but is slow and may have high
packet loss.

Dos this happen all the time on a variety of wifi points too ??

?????

Do you mean that if you run something with output to screen that you can
see the output continuing to move, but can't control the session ??

When you re-connect to the running session, does it time out again or work
continually after that ??

Are you trying to connect remote smb drives or printers etc??

Are you doing other work at the same time, email clients etc

I would guess networking issues based on what you say.

BUT

you haven't told us what hapens when you put the Samsung netbook on the LAN
and try it locally !!

I normally use on my office chair a connection over a slower network,  
using the grid,electricity network of my home.
So I tested the netbook directly wired to the server over a 1Gb-swith.  
Speed was very good but only for 10 min. Then the keyboard was locked.

Every time it locks the screen moves a little bit from left or right or  
vice versa. The only thing one can do at that moment is Ctrl-Alt-Shift-Esc.

In Belgium and Germany speed is almost Dsl.

The keyboard gets locked. No other input is possible beside  
Ctrl-Alt-Shift-Esc.

So, on the local network, on every wifi and with stick same problem.

I have the impression that it has something to do with video rendering
These netbooks don't have much of videocards.

I have one netbook acer with linux on it. Maybe I could try the same on  
this portable.

That isn't normal.

So

I would now try scandisk then re-install the latest NX client.

I use NX on netbooks OK.

Worth a go !!

Try the scandisk and re-install as I said first.
