c7×0 and cxx00 2.6 Kernel Information
January 9th, 2006 by Richard 'RP' Purdie 2.6 Keymaps copied from http://openzaurus.org/wordpress/howto/c7x0-and-cxx00-26-kernel-information/
The 2.6 kernels should take full advantage of the keyboard. As well as the standard marked keys, there are some unmarked combinations that have been added that people might find useful. Note that opie and gpe both change the keymap so these keys might change under these programs but should be valid on the console (or in raw keyboard mode using SysRq+R - see below).
c7×0
- The first Japanese key next to Fn is Ctrl
- The second Japanese key nex to Fn is Alt
- Fn+Left/Right Arrows switches Virtual Console (VC)
- Cancel is Escape
c1000/c3xxx
- Ctrl is technically Ctrl-Left (as PC keyboards traditionally have two Ctrl keys)
- The first Japanese key next to Ctrl is Alt
- The second Japanese key nex to Ctrl is Ctrl-Right
- Fn+Left/Right Arrows switches Virtual Console (VC)
- Cancel is Escape
SysRq on all models
On the 2.6 kernels, the SysRq key is mapped to the Alt+Home key combination. See above to find the Alt key. The procedure for generating a SysRq+x request is:
- Hold Alt
- Press Home as well
- Release Alt
- Press the second key (x in the above example) whilst still holding Home
Valid values of x are:
- R - Sets a “R”aw mode keyboard which switches the kernel back to its standard keymap rather than something set by gpe/opie
- S - “S”yncs the disks
- B - Re”b”oot the device
- U - “U”nmount and remount the root partition read-only
There are more key combinations so see the standard kernel SysRq documentation for more details.
