Hello,

KDE works fine in daily usage, but after making call using Google Hangout for 1 hour or so, it starts freezing for some seconds. The only thing I can do is using the mouse, everything freezes (sound, hangout, chromium, panel etc.).

I tried to change scheduling settings, but it did not help.

What else can I do?

I am using Kubuntu 13.10 x64 with KDE 4.11.3

Thanks,

Does toggling desktop effects or restarting the video hangout make a difference?
It sounds like your system may be running out of memory / video memory.

Restarting Chromium helps for some time, but this happens again later on. I have Intel i7 2690 w/ 4GB RAM, 1 GB Intel GPU & 2 GB Nvidia GPU

Do you think 1 GB is not enough for the video? I will also try disabling effects and using Hangout again.

I'm thinking your hw isn't the issue because it's pretty high end (ok very)

there's a Google page discussing the bandwidth setting and how adjusting it can resolve issues inc. a slow pc

I don't think it's a gpu issue but you could force the use of the Nvidia card, that would be a bumblebee or bios thing I'm guessing

you could also try determining if when the freeze happens there's an excessive i/o or cpu spike and from what process(s) if the desktop freezes you could try switching to a already opened virtual terminal (alt+ctrl+F1) running htop and then using Ksysguard to lower the priority (should work for i/o and cpu) or was this what you meant by scheduling.

Hi,

I just started using again my Linux system and the problem continues. As you told me, I opened another tty to check cpu consuming app and it was GoogleTalkPlugin for chromium. I changed its priority and IO scheduling policies via Ksysguard, but the problem still continues. It's weird because I dont have the same problem under Windows.

might have more responses in the Hangouts forum http://productforums.google.com/forum/#!forum/hangouts

have you tried using Chrome instead of Chromium?

if you have another de (Gnome, Unity, XFCE, etc or a minimal fallback window manager installed by default like TWM) installed you could test using that as it would preclude KDE as your cause

Thanks for answer and sorry for late reply. I just tried chrome and the problem is the same. It also happened with firefox too. I posted on hangout forum and will keep this post updated with the result.
