Oh dear that broke mounting root again.

Much fiddling later:

it appears that at some point the disk in lovelace has been part of a 3 disk raid array, the md superblock is still there (possibly left over from a previous life?), the newer kernels that where detecting this and making a partly formed md0 disk which then blocked root from being mounted cos it overlapped with the raid partition.

I did mdadm --zero-superblock /dev/sda (or something like that), and now it boot!

it boooooooooooooooooooooooooots!!!!!

lovelace can't update the nvidia kernel modules, looks like it's using a back ported kernel.

remove back ported kernel and went with stock one.

Wouldn't turn on


Second monitor wasn't set up, added it to xorg.conf as a second X Screen (this will allow for disconnections w/o affecting Screen0). Noticed that attempting to restart X lead to it hitting 100% and hanging. Killed it, and kdm brought it up okay the next time & for a re-test. Should be okay on reboot (didn't test this). Gnome didn't handle a screen stretched across the two screens well (lacking Xinerama support?), which is why I went with the two-XScreen approach. The nouveau driver supports xrandr properly, so would be a better choice for frequent re-connections (at a cost of worse 3d support).

Note: Why is it using kdm for gnome? Loading gtk and qt for login is expensive. 15:22, 8 March 2012 (UTC)
