HP Compaq CQ 58 with Ubuntu 13.04: Black Screen Problem

HP Compaq CQ 58 with Ubuntu 13.04: Black Screen Problem published on Keine Kommentare zu HP Compaq CQ 58 with Ubuntu 13.04: Black Screen Problem

Problem: Screen turns completely black during boot, when trying to recover from suspend (after a short moment of non-blackness) and also when trying to open the brightness & lock options.

How to deal with the problem:

To recover from black screen, switch to console. Close lid until computer is in suspend mode. Open lid again.

To fix the problem permanently, play around a little with the brightness controls (F2 and F3).

Note: This solution was found after certain other shots at fixing the problem which did not succeed. (Like installing new drivers for the Intel graphics chipset and adding the following script (taken from some place on the internet) under the name /etc/pm/sleep.d/00fixSuspend:

#!/bin/sh
#
case "$1" in
suspend)
;;
resume)
sleep 5
vbetool dpms off
vbetool dpms on
;;
*) exit $NA
;;
esac

All of this neither helped nor did any harm, so I suppose it is not necessary to fix the problem. If this should turn out to be false, please leave a comment.)
