How to use a terabyte of RAMHow to use a terabyte of RAMPosted Mar 13, 2008 15:49 UTC (Thu) by landley (guest, #6789)Parent article: How to use a terabyte of RAM
When I suspend/resume my laptop (A Dell Inspiron E1505 that came pre-installed with Ubuntu, since upgraded to x86-64 Kubuntu 7.10), about 10% of the time the keyboard and touchpad are dead when it comes back. The rest of the system is still working fine; if I press the power button the "log out/suspend/hibernate/restart/turn off" dialog comes up (useless if I have no mouse and keyboard), and if I plug in a USB mouse or USB keyboard I can use the system normally. (And if I suspend and resume it again via said USB peripherals, the keyboard/touchpad controller usually revives itself when it comes back.) If I don't happen to be carrying USB peripherals around with me, the only thing I can do is hold the darn power button down until it hard powers off, and then reboot it. I wind up doing this, on average, about twice a month. So there _is_ more to life than just trusting your battery...

(system -> preferences -> power management, general tab, "when the power button is pressed: suspend"). Alternatively, if you have a suspend key on your keyboard, that might be handled by the BIOS instead of the OS, and might trigger a suspend event.

(See http://www.atomicmpc.com.au/forums.asp?s=2&c=16&t... for details.) However, all I had to do was edit /etc/acpi/powerbtn.sh and replace the call to /usr/bin/dcop with a call to /etc/acpi/sleep.sh. I'm aware this is probably not the _approved_ way of doing this, but as with most "chainsaw, shotgun, and duct tape" solutions, it works just fine for me...

I suggest that you do not design your Dell inspiron laptop into a mission critical transaction processing system. Or that if you do, you should consider avoiding sleep state :-)
