I have the same problem, using nvidia-glx-legacy on two of my computers, both of which have a geforce 2 , one being a GTS Pro (Asus), the other one is a MX 400.
Whenever I use the nvidia driver with Xorg, I get lockups. Note that this ONLY HAPPENS on Xorg. If I use XGL, the system remains perfectly stable. This is SURELY a Xorg bug/incompatibility with the nvidia driver. I can confirm this on both of my systems. ** Attachment added: "Nvidia error code on a crashed system" http://librarian.launchpad.net/7220571/nvidia-bug.log -- nvidia-glx crashes/lockups https://bugs.launchpad.net/bugs/13530 You received this bug notification because you are a member of Kubuntu Team, which is a subscriber of a duplicate bug. -- kubuntu-bugs mailing list kubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
