Installed Ubuntu on new laptop with Win8.1 installed from USB key. Worked fine and could dual boot. Installed updates and rebooted when instructed Got following message when booting into ubuntu:
Kernel panic - not syncing: fatal exception in interrupt
drm_kms_helper: panic occured, switching back to text console
(does not switch back and just hangs) Reinstalled ubuntu but exact same happened although new version was installed on new partitions Windows 8.1 loads fine How do I fix?
eto edit the Ubuntu option and add "nomodeset" afterquiet splash. Then F10 to boot. If that works, let us know and we'll update with how to make the change permanent. – amanthethy Sep 21 '14 at 05:47
