I don't know if this is the cause, but
I ran out of disk space, coudn't login and things broke...
After enlarging the system partition, some problems sorted themselves out,
but I lost some settings and the nvidia graphics driver. Reinstalling that fixed it and compiz worked perfectly.
But sound dosen't quite work right and now fails to init on boot.
running sudo /sbin/alsa force-reload will make it load, but sometimes I have to run it several times to make both soundcards to be recognized. once loaded they work well.
There were also two freezes with corrupted screen after login.
I am using both sound devices side by side:
Intel HDA for regular sound set as index 0
M-audio 1010LT for studio work set as index 1
mixed through external mixer
I am also using an M-audio 1x1 usb midi interface and a usb keyboard
I just got a korg nanokontrol (usb) and changed to a usb wheelmouse from a ps/2 mouse because I needed the middle button
the nanokontrol prevents the 1010LT from starting if it's plugged in at boot.
plugging it in after boot, it works fine.
I haven't tried changing the mouse back again.
I still haven't got the boot screen working right yet, so I think other things may be screwed up.
