No Video on Bootup With 3.0.0-15.25

[Scott Talbert]

I just upgraded today to 3.0.0-15.25. My system appears to boot up normally, but when X starts, the display is blank. The backlight is on, however. When I revert back to 3.0.0-14.23, everything works again. My system is a Dell Latitude E6410 with Intel Graphics. I can log in by entering my password, but still can't see anything on the screen.

Dell Latitude E6510, also affected, exact same symptoms.

I can get display with safe boot from grub, but even then I can get screen blacked via mplayer. I'm postulating this is KMS bug.

Sure enough

[ytti@lintukoto ~]% grep nomodeset /etc/default/grub
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset"

Does 'fix' the problem.
