Installing OpenSUSE 12.3 on a ThinkPad T500
Lenovo Thinkpad T500 2056-Y4R, BIOS 6FET92WW (3.22), ECP 7VHT16WW (1.06)
This installation instruction describes these parts that do not or do not completely work after my OpenSUSE 12.3 DVD installation using KDE 4 as window manager. If anything does not work as expected, please have a look at the older Installation of OpenSUSE 12.1 on a ThinkPad T500 for possible workarounds that I forgot to mention here. However, almost everything seems to work fine.
Since the default BIOS settings Switchable Graphics caused high power consumption in the past, I changed the BIOS settings from Switchable to Internal graphics before installation. Please read Switchable Graphics for the pros and cons. Note that I did not test the ATI graphics.
# mkinitrdin order to prevent loading of unnecessary modules.
Suspend to RAM works out of the box. Note that I neither tested the default Switchable graphics BIOS setting nor Suspend to Disk.
LCD Brightness Buttons
The LCD brightness buttons do actually work, however, there is no on-screen display feedback.
