I just got the email back from the vendor: my box has both kernels installed, so I'll just roll back. I've done some searching on the web in the meantime, and it seems all one has to do is to change the defaults is to edit the file /boot/grub/menu.1st and select the line: default 0 and change "0" to the number corresponding to 2.6.24-16 (the non- safe mode version) in the list of kernels. Correct? I did read on the Ubuntu forums that by a poster's performance tests, 2.6.24-18 does run significantly faster. So perhaps a package compatible with it might be desirable. Or at least downloaders of SD4L should be warned that they will need to choose to boot to the earlier kernel to save themselves (and you!) the hassle of re-answering this question. =) Stewart |
