Let me quote NVIDIA's "Common Problems" page: "This can be caused by a variety of problems, such as PCI IRQ routing errors, I/O APIC problems or conflicts with other devices sharing the IRQ (or their drivers).
If possible, configure your system such that your graphics card does not share its IRQ with other devices (try moving the graphics card to another slot if applicable, unload/disable the driver(s) for the device(s) sharing the card's IRQ, or remove/disable the device(s)). Depending on the nature of the problem, one of (or a combination of) these kernel parameters might also help: Parameter Behavior pci=noacpi don't use ACPI for PCI IRQ routing pci=biosirq use PCI BIOS calls to retrieve the IRQ routing table noapic don't use I/O APICs present in the system acpi=off disable ACPI" In other words I suggest you to follow these steps: 1) turn on your computer 2) after you see the BIOS you will see the GRUB menu which contains a list of kernels that you can use to boot into Ubuntu. Select the 1st entry with your keyboard (do not press Enter) and press "e". You will see 3 or 4 lines and you will have to select the 2nd line (i.e. the longest line) with your keyboard and press "e". Get to the end of the line and add one of the recommended parameters (e.g. pci=noacpi) so that the line will look similar to the following: kernel /boot/vmlinuz-2.6.27-7-generic root=UUID=756f974e-86b9-4ba1-b5b7-33dd59f616ce ro quiet splash pci=noacpi Then press Enter and you will get back to the previous screen. Select the 2nd line again but this time press "b" and let Ubuntu boot. 3) If the problem persists you will have to repeat the same procedure with a different parameter. Once you've found a parameter that works for you I will give you further instructions on how you can make that parameter permanent. Let me know how it goes. -- X fails to start with proprietary nvidia driver https://bugs.launchpad.net/bugs/284715 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
