The new laptop (Dell Inspiron 5000) has one or two teething issues. Which is disappointing as I had installed Ubuntu on the XPS I had previously (at work) with no problems at all, so thought this laptop would be a safe bet.
At present I can’t use suspend. Although the laptop sounds like it is resuming, the screen remains blank and I have to do a hard reset. It’s a pain starting everything up again whenever I shut down, so I thought I’d try hibernate instead.
For some reason this is not available on the system tray menu. To hibernate from the terminal the command is:
sudo pm-hibernate
My laptop resumes fine after this. To add the option to the system tray menu, I edited the file
/var/lib/polkit-1/localauthority/10-vendor.d/com.ubuntu.desktop.pkla
I changed the setting ResultActive to yes in the two places below:
... [Disable hibernate by default in upower] Identity=unix-user:* Action=org.freedesktop.upower.hibernate ResultActive=yes [Disable hibernate by default in logind] Identity=unix-user:* Action=org.freedesktop.login1.hibernate ResultActive=yes ...
I also decided it would be useful for the laptop to hibernate if I shut the lid. To do this I edited the file
/etc/systemd/logind.conf
I replaced the line below:
#HandleLidSwitch=suspend
with
HandleLidSwitch=hibernate
Reboot required after these changed. Now it will at least hibernate. Thanks to this blog post (and the comments) for the guidance: http://ubuntuhandbook.org/index.php/2014/04/enable-hibernate-ubuntu-14-04/
Next I need to get the audio working…
