Title:
Utopic freezes while booting the ISO image
Status in “linux” package in Ubuntu:
New
Bug description:
I'm testing an Ubuntu GNOME Utopic 20141016 amd64 image. When booting
the ISO (using grubentry method), the screen freezes and becomes
unresponsive after 3 secs of showing up the Gnome desktop screen. Not
able to continue beyond that or even to the installation step. Do not
face this issue with Beta 1 or Beta 2. The md5sum for iso file is OK.
Problem is repeatable everytime.
ProblemType: Bug
DistroRelease: Ubuntu 14.10
Architecture: amd64
UpgradeStatus: No upgrade log present (probably fresh install)
I don't know how to capture information about the crash, although I
went through debugging guide, as can't get to part where I can get
console / terminal access.
I am attaching my laptop profile.
