I am fairly new to this, so please excuse if this post is misplaced or incomplete.
Ubuntu is running pretty smooth on my laptop, but I cannot suspend more than once before restarting and it is really frustrating. When I try to suspend again, it just logs out.
Please help me out here.
I am running
Distributor ID: Ubuntu
Description: Ubuntu 12.04.1 LTS
Release: 12.04
Codename: precise
on an X301 Lenovo.
How big is your swap partition? Your swap has to be at least as big as your ram is you want to use suspend properly.
Twice is better.Quote:

Additionally, it may be helpful if you could provide as much information about your hardware as possible.
Thank you for the replies.

these lines sound suspicious, but are hieroglyphs to me
My partitions areCode:/usr/lib/pm-utils/sleep.d/49wwan suspend suspend: success.

so maybe swap is to small, but then I don t understand why it would work fine the first time after boot?Code:Device Boot Start End Blocks Id System

/dev/sda6 235636736 239605759 1984512 82 Linux swap / Solaris
Does this information confirm that the problem is caused by a too small swap partition?
Probably not. Having a look around, it seems to be a problem some others are having, with no current fix.Quote:
