Laptop lid problem

[rex]

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.

Tried this

# sysctl hw.acpi.reset_video=1
hw.acpi.reset_video: 0 -> 1
#

No luck

I'm also using intel driver.

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.

you sure switching to xf86-video-i810 will solve the problem? DRI and i915 are already enabled. How do I make sure that glxinfo reports direct rendering is enabled?

Thanks

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.

In glxinfo ouptut (in first several lines) it should be displayed Yes.

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.

It is xf86-video-intel bug, you can not compare nvidia(nv) driver with intel driver. Reasons why it work on some intel cards and on some it does not is because xf86-video-intel driver supports some intel cards better than others.

It is not Dell/HP/Toshiba/IBM etc. fault.
