I gave OpenSolaris 2009.06 a shot, on an old HP nx6320. Already during the install, it slows down considerably, and got stuck completely. The third effort succeeded finally. Now, after reboot, the system is normal, if not snappy, for a few minutes, then the mouse starts to react slow, that is, it jumps as if it would read the position data once per second, and after a few more minutes it freezes completely: no more keyboard, no more mouse, and it doesn't answer to ping-s any more. Hard reboot, and the same starts all over. Since it is a fresh install from the original CD, I guess, there is a serious problem. The same notebook runs XP and Ubuntu very well; memory test goes through for > 24 hours.
I have tried an update, which resulted in an 'opensolaris-1' grub entry, and it behaves likewise. It has 4 GB of RAM. Just after boot, 31% thereof are consumes for programs, 0% for cache, by the desktop alone. Is that normal? Uwe -- This message posted from opensolaris.org
