i am experiencing the same problem with a 8400GS on a Dell XPS M1330. what i see here, is that the wrong kernel module is loaded for this videocard. even after manually installing nvidia-glx-new, this error is thrown:
"Error: API mismatch: the NVIDIA kernel module has version 71.86.01, but this NVIDIA driver component has version 169.09." this error is persistent, doing a: rmmod nvidia modprobe nvidia_new solves it for the current session, it falls back to legacy however after a reboot. -- Hardy LiveCD fails to identify nVidia 8400M GS on Sony Vaio SZ https://bugs.launchpad.net/bugs/175436 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
