This has been affecting my installation routines for a number of versions of Kubuntu now. I found a workaround that involves temporarily disabling nouveau until nvidia drivers can be installed:
Boot from the Ubuntu installation media. When the boot menu appears : Highlight Try Ubuntu without installing and press the E key. Add the nouveau.modeset=0 parameter to the end of the linux line ... Then press F10 to boot. Having entered the desktop start the installation process, once completed restart the PC. Again. When the GRUB boot menu appears : Highlight the Ubuntu menu entry and press the E key. Add the nouveau.modeset=0 parameter to the end of the linux line ... Then press F10 to boot. Now install the latest official NVIDIA drivers. This is a bug that needs to be addressed. Anyone new to *ubuntu who encounters this would assume that installation is impossible, even using the Live Disk has become a problem. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1217585 Title: System hangs after some time with nouveau and GT240 To manage notifications about this bug go to: https://bugs.launchpad.net/nouveau/+bug/1217585/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
