This happened to me installing an no-name generic Nvidia Quadro NVS 290 pci-x into a Dell Optilplex OptiPlex 210L 32 bit machine. (Dell service tag FYF7Y91), which has an integrated Intel gpu using the i915 driver. There is no way to 'disable' onboard video but you can 'autodetect' added cards.
I took a video of the bootup with my phone and basically linux reboots right after it tries to load the i915 driver. My workaround was to add i915 to the /etc/modprobe.d/blacklist.cfg but it still didnt fix the overall problem. nomodeset works but the problem with adding 'nomodeset' is that this prevents nouveau from working at all. Read around the internet and it needs kms modesetting in order for it to work properly. If you use nomodeset, then X boots up with software rendering, it doesnt use the 3d graphics card at all. running 'glxinfo' will show gallium / softpipe / llvm. Installing proprietary Nvidia driver does not help either. I poked around some kernel logs and basically it looks like nouveau itself crashes and dumps a bunch of info. In the end I gave up and am going to try using a different card. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-nouveau in Ubuntu. https://bugs.launchpad.net/bugs/1128801 Title: Adding second graphics card causes infinite reboot loop for Ubuntu, but Windows boots.
