Bug Description

This bug is from AskUbuntu. I am filing it for somebody else. The question is at

On either of my two computers, the whole desktop gets extremely slow after Skype runs for about 20-30 min. That is, I can no longer use it, the mouse will only move every other second for some pixels, or not at all; keyboard input does not seem to work (at least alt+f4, etc.)

 My laptop runs on an Intel Core 5, my desktop an AMD Phenom 9650. The former has an Intel HD 3000 graphics processor (rc6 and stuff enabled, which never caused crashes without Skype enabled), the latter a Nvidia GeForce 8400 GS with proprietary drivers.

I have only added Google Chrome and Dropbox to my system.

Neither in syslog nor in the xorg log are any entries near the time of the freeze. Starting Skype in the Terminal wont give any results, it seems to crash before reporting.

Thank you very much, this bug report was filed on my behalf - since the askubuntu-question was mine. The problem described does no more occur on my machines, however, I did nothing to prevent it, so I cannot tell why. Skype runs well again without freezing my desktop or laptop.

So i suggest closing this report unless someone else is having the same problem.

But thank you, Robert!

I am still having this issue, I'm running Skype on Ubuntu 11.10.

I can't start skype without the entire system freezing.

@cunnama It looks like the same issue, please describe in more detail. Also, I need to know the version of Skype you are using and the Linux Distro and version you are using. Also, please mark this bug as affecting you so it can be marked as confirmed.

Hi Robert,

I am running Ubuntu 11.10 kernel 3.0.0-17-generic 64-bit and Skype 64-bit.

Basically I had skype in the startup list and the computer would be unresponsive immediately upon boot.

I've since removed it from startup but if I try and start skype manually the entire system freezes. The mouse seems to jitter around slowly as I move it making it appear to be a memory issue but I can't force shut down or anything. I have to power down in order to get out of it.

Starting from a terminal does not cause an output and I have also looked in syslog and the xorg log and there doesn't seem to be any info about it...

Hi Robert,

I've updated to 12.04 LTS and Skype seems to start and run normally once again.

I guess it will remain a mystery.

Funnily enough, I only started having this problem after I upgraded to 12.04.

A few more details:

 - The system starts reacting very slowly because skype is using up all available system memory almost immediately after you log in to it. (Note: it is on log-in, not actually starting skype; disable automatic log-in to prove it).

 - After some minutes, skype crashes with an out of memory error.

 - Subsequently starting skype it runs without problems - the problem only happens the first time skype starts on a cold boot.

 - The problem occurs with both the version of skype in the repositories, and the deb available from

 - There's a thread on the skype forums about this bug, with several guesses as to the cause and suggested workarounds:

Simon, please see if the new 4.0 version available at solves this problem. If that is the case, solving bug #1013258 will solve this bug as well.

Annoyingly, for the past week I hadn't had this problem at all. (Well, good for me, but annoying for bug-fixing purposes). I've just upgraded to 4.0 today, and it seems to be fine, but I don't know if that's because it's actually fixed, or if it's just that whatever changed a week ago meant I'm no longer affected.

Sorry that isn't more helpful. All I can do is report back if it ever starts happening again.
