Of course the first part (Arduino IDE) can be downloaded for free and

IIRC Ubuntu 9.04 includes the FTDI driver already.

I'd like to see you post exactly what you did in order to get X running. Where 
did you get the drivers? Where in your filesystem did you put them? How did you 
tell Ubuntu's package manager they were custom? Did you alter System-

More details on getting X to work:

At first I tried to use ubuntu's (System->Administration->Hardware 
drivers) identification of the hardware that would typically result in 
suggestion to use nvidia propriety drivers. It did, and I went with it 
suggestion. Version 180 (IIRC) of the nvidia drivers was installed but 
all It didn't work - I got corrupted 6 windows instead of one nice 
LED-lit screen :-)


Next, I realized and saw on the web (and docs) that version 180 of the 
drivers do not support my relatively new GPU. I decided to give "nv" 
drivers a shot. I'm not a gamer anyhow. nv didn't work nice with my 
screen - I failed to see the full resolution of it. Maybe I could have 
make it work with nv, but I saw it simply takes too much time so...


After sawing on nvnews.net (forums) that my GPU is supported (beta? 
don't recall) in version 185 of the drivers (which is to this time the 
latest stable nvidia release of drivers for linux) I decided to install it.
You download a nice binary from their site. Its a self contained 
installer that you just need to run as root. There's a wizard there that 
collects your answers and preferences, and does the rest, including all. 
Ubuntu package manager on the laptop is not aware of this package. 
That's the downside of course. Note that their installer installed 
binaries all over the system, installs a kernel module, overwrites (asks 
permission to) your xorg.conf and more, so its quite obtrusive. But, 
AFAIK their installer job-quality is ok and has an uninstall feature 
that actually works (as far as I can recall from the past).
Like mentioned before I still downloaded an xorg.conf suggested on 
nvnews.net forums and only after using it everything worked ok. Mail me 
if you need it.


cest tout.

man synclient

By the way, my acer toggles mousepad-on state every time you push it, so your 
situation is definitely not normal. I have a feeling the next Ubuntu will fix 
it, and maybe you can file a Ubuntu bug report to make sure of that fact.

While I do tend to agree with what you say... who are those "people"? Is it 
the poor salesman who gets payed 22nis/h for seeling on office depot? or the 
supplier/vendor?

If you are molesting a poor kid, please see this: http://xkcd.com/225/

If you are actually talking about the vendors, how are you exactly contanting

touchpad can't be re-enabled after disabled

2009-09-04 Thread Boaz Rymland

Hi,


I have a new laptop (Acer 5738 mentioned in a different thread) which I 
have a nagging problem with:



I have this nice and useful button right next to the touchpad, for 
disabling it (when working with mouse and using the keyboard and prefer 
not having pointer distracted by occasional touches on the touchpad 
while typing).



The problem is that when I use it, all is gute and the touchpad is 
disabled but when I try to re-enable the touchpad its still disabled. 
This is fixed only after a shutdown of the system, or "suspend" of it.



I failed to find any useful help on the web.


When I run hal-device or lspci (-v) I find nothing like "touchpad" or 
"synaptic".



Any tip?

Thanks,

Boaz.

For my new desktop PC (which I already ordered and should receive next
week), I specified an ATI display card.

Hi David,

Try first to use View pane and switch to the classic view.

Re: Alsa Underrun problems with Skype and Skype ALSA problem on Ubuntu jauntu

2009-09-04 Thread Lev Olshvang

Hi Geoff,

Perhaps you know what is going wrong with Ununtu jaunty Skype - recently 
I upgraded from ububtu 8.10 to 9.04  and although sound work well with 
all non-skype applications the Skype complains that it have problem with 
audio playback and capture device.


Strace shows the problem is :

ALSA lib pcm.c:2205:(snd_pcm_open_noupdate) Unknown PCM cards.pcm.hdmi


And I saw in ubuntu forums that smbody  just installed skype build with 
static oss bound,

but I woul dlike to stay with alsa model.

I get the same problems (breakup) and other random problems under both 
MacOS and Windows on several different computers. I think it is a 
SKYPE problem, not a Linux one.


You can turn on a display of packet information and see how many 
dropped or out of sequence packets you get. You can improve it if you 
open a UDP port on your router for SKYPE. The port is a user setting 
so you can do it for more than one computer if you share a router.


BTW, SKYPE is very careful to keep the exact details of their protocol 
hidden, though some people have packet sniffed it. Because it is 
hidden, one of the things I can't do is to give it priority (QOS) over 
other things on my router. Therefore SKYPE is often a less than 
desirable way for me to communicate. I use SKYPE, and yes they do get 
some of my money, but most of my money goes to SIP providers who use 
an open protocol. YMMV.



Geoff.

Thunderbird problem

This is not a Linux question but it is a FOSS related question.  I am running

Re: Automated GUI testing with JS and AJAX

2009-09-04 Thread Lev Olshvang




Just my 2 cents:

I think that combination of iMacros +GreaseMonkey plugins can be used
for regression tests,
perhaps the  iMacros alone  is just sufficient for your purposes.

  Leonid,
  
I'm pretty sure there are two possible non-DIY alternatives
1)  maybe  ratproxy - it's pretty cool for webapp software security
assessment and it might cover some of your test use cases
  
2) probably Mochitest - https://developer.mozilla.org/en/Mochitest
  
Just a thought.

  Hi, all,
At my work we encountered a problem and it looks like we are
re-inventing the bicycle. Someone here surely has an experience with
that.
We have a regressions testing lab. As a part of the testing we have to
work with the web-interface of our product. (I'm intentionally vague,
the details are quite irrelevant to the problem). The testing scenario
includes action items like "press the button with caption 'Advanced
Settings' on it".
This is implemented as a C program with sockets interface, so "find a
button" actually means "look for a substring in the received HTML
code" and "press the button" means "create an HTTP POST message and
send it".
However, recently we have added some _javascript_ and AJAX to the
web-interface and now the testing environment must be able to run JS
and even cope with things like replacing part of the DOM tree. We can
see three possible directions to tackle the problem:
- Further fix our great testing program. After all, we know what AJAX
can return -- we can manually open the connection it would open, parse
the response, etc. Looks ugly and has a potential to turn into
maintenance nightmare.
- Setup a headless X server with Firefox running inside and some sort
of scripting/management add-on. If someone has an experience with such
a setup, I would appreciate pointers to specific add-ons you used.
- Somehow hack off the GUI from any open-source browser and link it to
our program, i.e. use it as HTML parser and JS machine. Looks
unpredictably complicated, maybe not even feasible.
