I notice a strange thing, when ever I close the lid of my laptop and open it up back display don't turn on, the only way I was able to find to turn it on again was to switch back to console mode (Ctrl - Alt- F1) and then back to X (Ctrl- Alt - F9). Has any one noticed this before and is there a fix for this.
I tried this in two Dell Laptops Latitude D420 Latitude D800 |

It could be Xorg drivers fault after all.
What driver are you using? I had same experience with intel driver when DRI was disabled. |

Try this command with superuser priviledge:
#sysctl hw.acpi.reset_video=1 , close and open the lid again.

Then you have same problem like me (it is xf86-video-intel bug)
enable DRI if it is not enabled.(load drm and i915 module, and make sure that glxinfo reports direct rendering is enabled) If that doesnt help switch to xf86-video-i810. |

At least It solved it for me, but maybe i810 will not work at all with new Xorg server (>1.5)
i810 is marked as broken, it does not build with newest libdrm so portdowngrade libdrm to 2.3.0 and after that remove BROKEN from i810 port Makefile. Quote:
I should really check is this intel bug fixed in newer versions, but I currently dont care .... |

To me this seems to be a problem with Dell H/W rather then bug in intel driver. I tried this in Acer laptop with Intel driver worked like charm. Then trien on different Dell dimension laptop with nvidia (nv) driver, problem was there. Infact this time I tried even without installing X, and it was even worst.
While X is running, I was able to turn the display on by switching to TTy 1 and back to X. But when X is not running only way to turn the display on again is to reboot the system ![]() So I've tried this in 2 different Dell H/W, all of them having this problem and tried on one Acer H/W worked without problem. So any one conscedring to purchase Dell Laptop for BSD might wanna conscider this. |
