if laptop is not pluged in, during the kernel is loading Can you find out which driver is actually doing this. Danny can this be hal or something from userspace?

That means if AC is plugged in, everything works fine? Please paste lsmod, so that we could guess which module could cause this. I expect if you unplug AC adapter later, the brightness will go down again? -- 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.

Can you find out which driver is actually doing this.

if AC is plugged in at start time, it set the maximal possible brightness level, and at least you can see, what is going on on the screen, but u still can not change brightness (back light).

I expect if you unplug AC adapter later, the brightness will go down again? no, the back light does not changes.

There is no specific laptop ACPI driver loaded. Video driver (which couls/should do brightness switching is not used at that times yet). Maybe best is you install the latest 11.0 in a small partition (if you still have some free place). If this is still an 11.0 issue, the priortity of the bug increases and we even might get some help from Intel ACPI mainline people. If not, we already have a clue that it might got fixed between 2.6.22 and 2.6.25-rcX. -- 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.

Hit 'e' for edit and exchange the param vga=xxx to vga=normal (You may want to do this when booted in /boot/grub/menu.lst, it then permanently removes the splash screen at boot time). Can you upload dmesg output pls, and give as a hint at which position of the boot messages the brightness switch happens. Also try to boot with boot parameter: 1 Then you will only boot into runlevel 1 and a lot services are not started yet, is the screen still bright? Can you also attach output of acpidump command (as text/plain), pls. -- 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.

This one is known to be broken on 10.3.

@Thomas, is there any easy and fast to follow HOWTO for testing opensuse 11... without affecting the running system? I expect there is no live DVD for 11.0 out yet? Maybe you have an external USB disk you can install on or just still a bit of free space on the disk? You could possibly resize a partition with 10.3? We should really go for 11.0, it's a waste of time for 10.3. If we really find easy things to backport, it can still go into 10.3.

While looking for a BIOS is always a good idea..., your BIOS supports the IGD Integrated Graphics Device for which there is no Linux driver yet, but Lenovos also have such a device and do not switch to a black screen on battery... (If you find a BIOS update then check this *after* upgrading): Do you have any battery saving options in your BIOS configuration? Could you try 11.0 booting with: osi="!Windows 2006" boot parameter, pls. Also for 11.0: If you are in grub, hit ESC and enter the grub text menu. Hit 'e' for edit and exchange the param vga=xxx to vga=normal Could you point me to the line when the screen turns black when booting in your dmesg of comment #10. If you boot with AC plugged in and remove it later, does the screen turn black? -- 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.
