Plymouth is not responsible for built-in backlight, but just uses the stuff the kernel is providing. I can imagine that you could have a black screen between Grub2 and KDM, but KDM should be disabled normally. So this is either a Xorg or Kernel bug.

Then the backlight is working, but the screen-resolution is fixed on 1024x768 (instead of the native resolution of the Widescreen-Laptop) The other way that should work is according to some forum entries i studied to write the following line in the "/etc/init.d/boot.local": "setpci -s 00:02.0 F4.B=0" This will fix the backlight to maximum. In any case I think this is a problem of the Kernel itself (KMS). I'd also tried Ubuntu Live CD in a new version with the same result. The problem with that graphic controller alredy started with OpenSuse 11.4 which switched to KMS. Hope that there will be a solution very soon. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I want to try your package from home:jobeymayr but it's totally empty and I cannot find this package nowhere. I got prepared OpenSUSE 12.2 on USB Stick for testing any solution that could help in this issue. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
