Sleep issues on Ubuntu 10.04 on Dell Inspiron 5150
After resurrecting and upgrading an old Dell Inspiron 5150 for a friend, I installed Ubuntu 10.04 Desktop and installed all available updates.
I don’t have a ton of experience with Linux as a desktop OS, but I gather sleep and hibernate functions can be problematic. Hibernate definitely doesn’t work out of the box on this Dell unit, but that’s not a big deal; my biggest concern was a functional sleep operation, which also wasn’t working out of the box.
After a little Googling on the issue, I changed the following line in /etc/default/acpi-support
ACPI_SLEEP_MODE=mem
…to:
ACPI_SLEEP_MODE=standby
…and ran:
sudo /etc/init.d/acpid restart
This apparently results in reduced power savings, but it at least grants some functional sleep functionality on this particular laptop.
(It’s worth mentioning that with 512MB of RAM, Ubuntu 10.04 totally screams on this unit. Very responsive, rapid startup, fabulous range of applications right out of the gate… I’m impressed. Beats the crap out of WinXP on the same machine.)
