Hi, I have been able to get around this bug on IBM T60/x1400 running Kubuntu 12.04, by using kwin_gles desktop manager instead of the default one (kwin).
I had problems with sound slowing down and being very choppy when desktop effects were enabled, or when playing full-screen flash videos. I did not notice any problems with wifi. With kwin_gles I have absolutely no sound issues with desktop effects enabled. How to change the window manager see: http://weits.blogspot.cz/2012/02/kwin-gles-as-default-window-manager-in.html I'm not X expert, so please take the following lines as my humble opinion. I belive, that the workaround is caused by the fact, that kwin_gles uses EGL for rendering, while kwin uses GLX. So maybe this bug can be avoided on other distros and window managers by setting them to use EGL instead of GLX. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/879790 Title: Sound doesn't play properly after upgrade from 11.04->11.10, also affects 12.04 To manage notifications about this bug go to: https://bugs.launchpad.net/xserver-xorg-driver-ati/+bug/879790/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
