Putting this under linux-restricted-modules, as I suspect it's related to fglrx.
Re-opening, because I see the same thing in Hardy, using kwin-kde4 with compositing features enabled. I suspect that it may be related to 3d acceleration, hence why Alexei found it didn't occur with metacity. Kubuntu-KDE4 Hardy, ATI Mobility Radeon X600 with fglrx drivers from repositories (hardy-backports). ** Changed in: linux-restricted-modules-2.6.24 (Ubuntu) Sourcepackagename: compiz => linux-restricted-modules-2.6.24 Status: Invalid => New -- System lags after resume due to high hard drive activity https://bugs.launchpad.net/bugs/190585 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
