Randomly this morning when I turned on an old laptop, the backlight came on but nothing came on screen. Okay, thats weird, but I wanted to see what would happen. So then the lubuntu login screen came up, and the entire screen is a bunch of light blue vertical lines, the same color as the login screen.
I've tried lots of things, including goofing around with the screen, pulling up the recovery console, and running on battery. Nothing worked.
Last night someone else used the laptop and they said they did nothing out of the ordinary. Just used it and turned it off, leaving the power plugged in as normal.
The only issues I've had with the LCD is the LCD not even coming on at boot (A well known issue to this Laptop line) and randomly the screen will go black with some white-ish hue at the top for a second or two then go back to normal. I've never seen it where the entire screen is vertical lines.
Any suggestions?
