Unfortunately this is happening on Feisty as well to me. I'm using the latest Nvidia drivers with a GeForce 6800 PCI-express Nvidia card. System specs are below:
Intel Pentium D 830 (3.0gHz dual core) 2GB RAM Nforce chipset I experience the exact symptoms as above, at random times, using random applications. For example, last night's lockup occurred while I was surfing around using Firefox, while another one occurred while I was listening to tunes in Amarok. The Windows side of this box works fine. I'm thinking this may be a kernel / xorg issue as it's happened to me on other distributions with this box as well, so I don't think it's Ubuntu- specific. -- Xorg process freezes, uses 100% of CPU. Can be killed by remote terminal. https://bugs.launchpad.net/bugs/51991 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
