Public bug reported:
I'm not sure if my issue is a duplicate of other's, but suspend no longer works
on my system after upgrading to the latest -beta. This is on an AMD64 (64-bit
install) with an nVidia card, proprietary drivers not loaded. I started
running tests (gotten from
http://www.mjmwired.net/kernel/Documentation/power/basic-pm-debugging.txt) in
"recovery mode" to test Suspend / Resume:
Running:" echo reboot > /sys/power/disk; echo disk > /sys/power/state" reboots
my computer, but trashes my swapfile. After re-running mkswap on /dev/hda4
(and adding resume=/dev/hda4 to grub command line), I am able to resume, but
the text console is corrupted. Its difficult to describe, but pressing enter
just scrolls the ubuntu logo (which never goes away) to the left. At the
bottom, there is a garbled white strip with random pixel noise that increases
by one pixel each time I press enter. It does look as if it responds to
commands, though.
Runing: "echo test > /sys/power/disk; echo disk > /sys/power/state"
brings the system back fine, repeatedly.
