Title:
Screen blank or shaking if boot without nomodeset
Status in “linux” package in Ubuntu:
Incomplete
Bug description:
Booting with kernel 3.2.0-29 works normally. After upgrading to
3.2.0-52 the screen started shaking erratically and it was very hard
to make out anything on it. Adding the "nomodeset" parameter to boot
work as a workaround but also seems to make X.org use the vesa driver
instead of intel -> slower desktop.
