On a fresh install of 13.37 Slackware64, (dual-boot with Windows 7 for now), the screen goes blank during the boot process.
It is similar to previous threads mentioned here
, yet different. Same Intel graphics as link.
The display is black on the left 2/3 and white on the right 1/3. It's not a backlight problem, and booting with "nomodeset" makes the problem go away, but makes X suck. Logging in blind and running startx does not make the problem go away.
If I wait for the screen-blanking timeout, then press a key, I get the console back and everything works.
