I'm having an incredible amount of trouble installing Ubuntu on an Asus K501LX.
I'm booting from a USB drive, created by usb-creator-gtk. I've attempted Ubuntu 14.04 and 15.04, as well as Kubuntu 15.04 (all 64-bit).
When I select "Try Ubuntu", 15.x hangs on the Ubuntu splash screen, while 14.x seems to work. However, when I select "Install Ubuntu", both 14.x and 15.x versions just throw a bunch of SCHED_ERR messages and crash. Kubuntu goes past the load screen, but then goes to a black screen and hangs.
I've been through all of the troubleshooting documentation with no luck. My md5 hash is fine, running "Check disk for defects" yields an all-clear, fast bootup and secure bootup have been disabled. Does anyone have any ideas what could be causing this problem or how it could be remedied?
