-- script snipped -- |
| 28 |
|
| 29 |
Thanks lots ! -- I looked up [1], which has useful extra advice. |
| 30 |
|
| 31 |
However, it occurs to me that my keyboard (Sanyo 1989) is PS/2 , |
| 32 |
so the script will help only to enable restart via the mouse. |
| 33 |
There's a PS/2 setting on the mobo, which I've enabled, |
| 34 |
but might there also be something in the kernel which needs enabling ? |
| 35 |
|
| 36 |
Lots of people seem to have problems with suspend/restart |
| 37 |
& it seems to be somewhat random & vary with different makes of mobo, |
| 38 |
so any further suggestions here may help others in future too. |
