This worked for me. I had a unused Fiber NIC still installed and removed it. FYI: NIC Had LSI Chip (L2A1157) and I have a Nvidia Quadro FX 4800/PCIe/SSE2 graphics card installed.
Seems to be some type of Hardware & IRQ issue. Problem has been gone for last 2 days. Previously this issue would appear within half hour or so after logging in. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/996008 Title: GUI slows down significantly after random period of time.
