Resuming from suspend results in black screen
Status in linux package in Ubuntu:
This problem occurs with the most current snapshot of Hoary (kernel
2.6.24-14). The machine is a Shuttle SN95G5 nforce3 chipset with an
Athlon64 X2 processor. The video card is an Nvidia GeForce 7600 GT.
This is a desktop machine with a wired LAN connection.
I can suspend to RAM and it appear to finish properly. However, when
I then try to resume, I get the same result. The screen stays black
and X never displays. The machine is not entirely dead, though,
because the HDD light blinks every 5-10 seconds. Also, if I press
CTRL+ALT+DELETE, I get a flurry of disk activity and then it goes back
to the 5-10 second blinking. Fortunately, I can use the Magic SysRq
key combos to sync, unmount, and reboot the machine. The network is
not active during this and I cannot SSH into the machine or even ping
These results occur using the binary Nvidia driver. I did try using
the nv driver as well, but it was a couple weeks ago and so it isn't
quite a fair comparison. In that case, resuming from a suspend did
actually hang the machine requiring a manual reset. I was able to
successfully resume the machine with the nv driver, however.
I really hope I can get this issue resolved as it is one of the only
features not working with the latest Ubuntu on my system. I have not
specified a package for this bug as I'm not sure if it should go
against the kernel, the Nvidia driver, pm-utils, or something else.
