The good news is that when I tested Skype with the RC1 it did not work at all. So this represents an improvement.....

IF that is not a typo how is not working an improvement?

Any pressing NEED to move to Maverick? (You can get KDE 4.5.1 through PPA backports)

Re: Skype Unsuitable

I should have mentioned that I currently have KDE 4.5.2 installed. I am not sure that the version of KDE would affect Skype, rather I think is would be the new Kernel which Skype may have not been compile with.

I know that on Skype there is a button to change the size of the video, but my understanding is that it only changes the size on the received image. Double clicking on the received image puts it to full screen.

I have a computer savy friend with whom I have been testing the difference between Windows and Linux Skype for some time now. He sent me the image that he was receiving from me and his comment was that the resolution was not good.

I have attached the images from him for 10.10 and 10.04

I have for some time now been wanting to change from 10.04 because I have been having the following problems with my Laptop.

wicd does not maintain a reliable wireless connection and often breaks connection on high data rates. I have therefore reverted to using an Ethernet cable to connect my Laptop to my router.
My Laptop does not always boot up the first time. When it does it stops with a black screen. Pressing the power button closes it down but sometimes does not power it off. I then have to hold the power button down to turn it off. Normally after 3 attempts the system comes up and I can logon.
Shutting down the system does not always power off the Laptop. I then have to once again hold down the power button.
If Dolphin is not used for some time it just freezes with no response. I find that if I wait for a number of seconds it finally "wakes up" and does what I want.
AMD have not released a Catalyst driver for their ATI cards, but I believe that this may be the case for 10.10.
I have a second monitor connected to my laptop. To get it working properly after each time I boot the system, I have to go to system settings to set it up.

I am quite frankly surprised that 10.04 is a LTS given these problems. I am therefore very interested to see 10.10 improve to a point where I am happy to install it on my Laptop.

Re: Skype Unsuitable

We are working in the dark here because we do not know what your make and model is for your laptop, video chip, etc.

In a Konsole do
lspci
lsusb
lshw

Is your webcam built in or external? (IF external does it have a focus ring?)

Re: Skype Unsuitable

I have 10.10 installed on my desktop and am testing it before installing it on my Laptop which is an ASUS F3jr. I am using the same webcam for all examples and under not circumstances will I use the webcam on the laptop. The webcam that I use is a Logitech QuickCam Vision Pro for Mac. It is a 2-megapixel webcam with built-in autofocus and rightlight 2.

You are operating from a faulty premise. How Kubuntu (or any distro) works on one PC has NO bearing on how it will work on another PC, so your experiments on a nearly eight year old desktop will have no bearing on how Kubuntu may or may not run on your 3 year old ASUS F3jr. So the listings you gave will only apply to the machine you were on when you issued the commands.

In fact, how a distro will work on, say, an Gateway m675prr laptop will have little to no bearing on how it will work on the SAME make and model laptop, but one made a year later and with different versions of firmware installed. A friend of mine purchased a Gateway m675prr laptop and based on how it ran Linux I purchased the same make and model a year later. It turns out that mine had an upgraded version of the firmware. I put the latest distro that I was using at the time and it gave me problems that my friend's computer did not give running the same distro. It turned out that they had different chip sets on the mobo, and hence different firmware versions to compensate. It took several months before enough updates came down the line and it began working well. It has given an "out of the box" experience every since, but it is still running Jaunty and my nine year old grandson has no complaints.

However, as computer generations pass by, (3 yrs/generation) older hardware gets "legacy" treatment by the vendors (i.e., no longer supported) and changes to the kernel make older drivers less and less compatible. That, I fear, may be a problem with your desktop.

For your desktop rtlk-8139 Ethernet ports the current kernel supplies two kernel modules: 8139too and 8139cp. If one is flaky perhaps the other one won't be. The EIGHT year old Nvidia card has two options: the Hardware Drivers from the menu, or installing the Nvidia proprietary drivers. Also, with the PC having only a 1.8GHz CPU and 1.5GB of RAM running Skype becomes problematic, especially if you have a slow bandwidth ISP connection. KDE4.5.x has a significant memory footprint when you have only 1.5GB of RAM. One sure sign of that is when the Skype sound begins lagging the Video by as much as 10 or more seconds, or drops out, and/or the video is jumpy or skips a lot, or freezes.

How well your 3 year old Asus F3Jr will fair is another mixed bag. One user had no problems. He was installing Gutsy, which is quite old. He used the ipw3945 wireless driver module, but that module is not supplied with Lucid or Maverick. Another said everything works, but he had to use the CLI to install the xorg-driver-fglrx driver following these instructions .

I hope you are able to locate the source of my problem from the above listings.

You might want to consider either Puppy 5.1 or Xubuntu Lucid for your desktop, and even your Asus. Even then I doubt either will give you the Skype experience you are expecting. Your laptop has a problematic wireless chip and video card. The two models I looked at had 1.6 and 2.0 GHz CPUs, and 1GB and 2GB of RAM. If your's is like the first it probably won't give what you expect from Skype. If yours has the power of the second it may, especially if you use a distro with a lighter footprint, like Xubuntu.

Re: Skype Unsuitable

i have just upgraded to 10,10 and all looking great

UNTIL i tried to use skype today ...

i have had it working great on 10.4 but now am back to the issue of the pulse audio server

i am using a plantrontic usb headset , that i used to have to reset the audio control in skype from the default to the usb headset, but now on upgrade i only pulse audio in the preference settings

can anyone please help

??

I use Skype with Logitech V20 speakers and to get them to work with the microphone in the webcam I used: System Settings > Multimedia and from this I selected Phonon. I then made the speakers and mike the top preference. Once this was done, Skype used these devices. In your case with the plantrontic headset connected, you should see these devices listed in the Phonon list.

The main problem will be when you are not using your headset, ie not connected. I think the system should revert to the next device in the Phonon list.

Re: Skype Unsuitable

Thanks GreyGeek for your comprehensive analysis of my problems. Below are my comments on the various issues you raised.

I have found the only difference is in speed. I previously had Kubuntu 10.04 on my desktop with Skype and was able to use it successfully. Unfortunately I did not get my friend to send me the picture he received when I was using my desktop. All I know is that no adverse comments were made regarding image quality with 10.04. I checked the version of Skype on both computers and it
is the same version, ie 2.1.0.81-1ubuntu5. On the Skype website they list 2.1.0.81 as only being available for ubuntu 8.10! Am I therefore to assume that canonical have been able to get Skype to build a version for each of their distributions?

Both my desktop and laptop are connected to a wireless router and are networked using nfs. To backup my laptop last week, I copied 12.5 GB of files through this system and the rate was close to the limit of the router and the properties of the copied directories were the same on both systems. For the video card. I have installed the NVIDIA accelerated graphics driver (version 173) from the Additional Drivers options.

When Skype and Firefox are loaded about 0.54GB is used. Still plenty of margin for other applications. On both machines I have not noticed any lag between the Video and sound. My ISP connection is by Cable and its claimed Download/Upload speed is 30/1 Mbps. In general I find that Skype does not approach these limits.

Since SKype was working so well on 10.04, I decided to replace the Windows partition with Kubuntu 10.10. With 10.10, I no longer have any problems with the wireless network and can now watch online videos without any break in the connection. I am very impressed with the new network manager. For my display driver I use the opensource software from xorg-edgers. Details on what to do are found at https://help.ubuntu.com/community/RadeonHD. This site does not list maverick as an option but when I put their repository site into Synaptic, I was able to install drivers for 10.10.

SKype on my laptop for 10.10 sends 640x480 images and both processors are about 70% loaded with the total memory used is less than 1GB. My conclusion from what I have observed is that Skype encoding and decoding of images and audio is CPU intensive. It seems to me that if Skype does not have sufficient CPU power, it reduces the image size, eg to 320x240. Their website http://www.skype.com/intl/en/get-sky...omputer/linux/ shows the following system requirements.

# 1 Ghz processor or faster.
# 256 MB RAM.
# 20 MB free disk space on your hard drive.

Since my desktop has more memory and processing power, according to this I shouldn't have any problems. On my desktop during a Skype session, the processing power used by Skype was about 44%, Xorg 13%, pulse audio 14%, kwin 8% and sysguard 3%. What surprised me was the amount of CPU used by Xorg. On my Laptop, Xorg processing load is negligible.

From these results, Skype is CPU intensive and a processor speed greater than 3GHz is required for 640x480 images. Thus I will only use Skype on my desktop as a last resort.

Re: [Solved]Skype Unsuitable

Am I therefore to assume that canonical have been able to get Skype to build a version for each of their distributions?

Nope. Skype source is proprietary. Canonical does not have access to that source. I suspect that Skype built a conventional Debian package ... one size fits all (Debian based) Linux boxes and Canonical probably adds wrappers to make it compatible with Ubuntu/Kubuntu.

And, as I mentioned before, even with the same make and model of PC how well Kubuntu will install,
configure and perform, is dependent on the BIOS and firmware it contains.

Mobility Radeon X2300

This message pretty much says it all.

PRO/Wireless 3945ABG [Golan] Network Connection

The Meerkat Release Notes state that:

Laptops using Intel Corporation PRO/Wireless 3945ABG experience reduced wifi speeds of the order of 1Mb/s. To see if your laptop uses this card, type the following: "lspci -v | grep 3945ABG". (621265)

Which has been reported here.
A Bug Report #621265 states that the user can't get the

network speed over wifi is never faster than 150kb/s

. Some experienced more speed, some less, but none obtained the speed the wireless chip was supposed to give.

The iwl3945.ko module is available in Meerkat. It has the following parameters:

parm: antenna:select antenna (1=Main, 2=Aux, default 0 [both]) (int)
parm: swcrypto:using software crypto (default 1 [software]) (int)
parm: disable_hw_scan:disable hardware scanning (default 0) (int)
parm: fw_restart3945:restart firmware in case of error (int)

They can be used while manually using modprobe

sudo modprobe iwl3945 fw_restart3945=1

or by adding settings to /etc/modprobe.d/options.conf
options iwl3945 fw_restart3945=1 antenna=1

And here is a site that gives external methods for activating the Intel PRO/Wireless 3945ABG chip. It uses the iwlwifi driver, which is present in the kernel source but has not been compiled to give a kernel module (*.ko). So, that link gives you tips on using getting and installing the iwlwifi driver.

You can read this for additional suggestions.

Thus I will only use Skype on my desktop as a last resort.

That pretty well limits you to less functional VOIP packages. Have you tried Ekiga?
It is in the repository. It works pretty well IF you get everyone you want to talk to using the same server.
You can even set up your own server and restrict its use to you and your friends. Skype works much better than Ekiga and those two are pretty much the best desktop VOIP applications you can get. HOWEVER, IF your camera is compatible with voice and video chat you can use a Google gmail account to chat and/or video talk with some one else any place in the world for free. Like Skype, you can also call land and mobile phones anywhere in the world. And, there are other web-based free chat and video conference utilities that require only FireFox. You can Google for them.

Re: [Solved]Skype Unsuitable

I do indeed have the wireless card you suggest. I do not know if (rev 02) is any better.

Code:

03:00.0 Network controller: Intel Corporation PRO/Wireless 3945ABG [Golan] Network Connection (rev 02)
    Subsystem: Intel Corporation PRO/Wireless 3945ABG Network Connection

I downloaded an mpg audio file and the system monitor plot is shown below. As you can see, the peak rate was about 1.8MiB/s which is 14.4 Mbps. I also did a speed test between Milton Keynes, UK and Sydney, Australia using http://www.speedtest.net/index.php. The download was about 6Mbps and the upload was 0.9Mbps. These speeds are considerably faster than what you are saying. I am quite happy with these speeds as they are well above those required for skype.

All the people that I communicate with use Windows, so a non-skype option is not that useful. As you probably realize, the video can be stopped in skype to use voice only. I always like to see the person who is talking, so I provide my picture as well - particularly when dealing with family.
