Eris, Goddess Of Chaos, Discord Confusion Does my laptop risk overheating when I enable acpi? The answer is dependent on how old your laptop is. My old Compaq Presario 2100 did not work with ACPI enable because it couldn't control the thermal functionality. But my new laptop (macbook 2,1) it works great with acpi and is needed to get some stuff working. So I suggest you try enable ACPI and see what happens. If you laptop can't control the thermal functionality it will most likely just turn of and then you just need to install it again without ACPI and you'll be fine. The laptop it self has a protection that it turns if off if it feels it to hot so you won't burn anything. BR Dunceor
X11 very slow with SMP kernel
Hi! I can see X redraw the screen top down very slowly when I use the SMP kernel on my Thinkpad T60. I can actually see it draw the background first and then every widget one by one. I don't see this behaviour when I use GENERIC. I use an the amd64 kernel. I tried with a 2 month old snapshot and a freshly built GENERIC.MP checked out this afternoon with the same result. spaceman% uname -a OpenBSD spaceman.my.domain 4.2 GENERIC.MP#0 amd64 dmesg: http://www.hcl-club.lu/~jaj/foo/dmesg `X -version`: http://www.hcl-club.lu/~jaj/foo/xversion Is this a know issue? Do I need to rebuild Xenocara with special knobs to use it with bsd.mp? Could you point me into a direction to further investigate this? Best regards, Jona
