The correct kernel parameter should be acpi_backlight=vendor acpi_osi=Linux.
Add it to the end of the GRUB_CMDLINE_LINUX variable in the /etc/default/grub file.
Then run the grub2-mkconfig -o /boot/grub2/grub.cfg command ...

All distro releases have bugs – including openSUSE, many of which will of course be fixed via online updates in the coming weeks and months. However so far I’m not aware of any major bugs that will cause a lot of grief to legions of people.

I predict that the thing that will cause the most people to say “wtf!?!” in 11.2 is actually intended behaviour. YaST/zypper will not show nor perform updates that involve “vendor changes” (i.e. updating an official package to a newer version of the same software from packman) unless the user explicitly does some extra work.

You roughly have these coping strategies:

  • Don’t worry about it and stick with the old versions included in the distro no matter how many 3rd party repositories you add.
  • Manually go to the Repositories tab or the Versions tab in YaST Software Management, and manually select the updates you want – or manually specify the versions you want on the command line with zypper (note, you only have to do the extra work to change vendor once per package).
  • Set AllowVendorChange = true in /etc/zypp/zypp.conf – this way YaST/zypper will update everything to whatever has the highest version number – and let you ping-pong back and forth between package vendors, if that’s what you want.

In the future the tools are expected to be improved, so that the vendor stickyness becomes less annoying and obtrusive.

When you open the Automatic Updates tab in My Computer Property sheet, or from Control Panel, all of the Automatic Updates configuration options may be grayed out. This happens due to any of the following reasons:
You're not logged on as Administrator (or equivalent)
Automatic Updates Policy is enabled
Automatic Updates (and Windows Update) access is blocked via Group Policy
To make the Automatic Updates options configurable by the user (only for stand-alone systems), remove the restrictions 2 & 3 above.
Click Start, Run and type REGEDIT.EXE
Navigate to this location:
HKEY_LOCAL_MACHINE \ SOFTWARE \ Policies \ Microsoft \ Windows \ WindowsUpdate \ AU
In the right-pane, delete the two values AUOptions and NoAutoUpdate
Navigate to this location:
HKEY_CURRENT_USER \ SOFTWARE \ Microsoft \ Windows \ CurrentVersion \ Policies \ WindowsUpdate
In the right-pane, delete the value DisableWindowsUpdateAccess
Using the Group Policy Editor - for Windows XP Professional
Click Start, Run and type gpedit.msc
Navigate to the following location:
=> Computer Configuration
==> Administrative Templates
===> Windows Components
====> Windows Update
In the right-pane, double-click Configure Automatic Updates and set it to Not Configured
Then, navigate to this location:
=> User Configuration
==> Administrative Templates
===> Windows Components
====> Windows Update
In the right-pane, set Remove access to all Windows Update features to Not Configured

There seems to be a problem with recognizing the ati-card as a mobility-firegl-V5700; instead it is seen as a HD3650, which is slightly different, resulting in different drivers.
Bios upgrade to >1.18 fixes this; then also a new driver for the firegl is needed instead of the hd3650 driver...

link to bios-update
link to driver
explanation etc.

After kernel update on Suse 11.0, the kde 100%cpu hang happens again...
removed ksmserverrc to fix this.

On samwise with 11.1 , this didn't help;
removing kpowersaverc does seem to have fixed this.
