Suspend fails on Sony Vaio SZ650, nVidia 8400M GS and nvidia-glx-new

Failed suspend...

Unfortunately making these changes breaks suspend when rebooting in STAMINA mode (intel 965), so perhaps the configs will need to be switched a la the xorg.conf switching script.

Ideally, xserver should be able to automatically select the right driver (and options) when switching, if no xorg.conf is present. In testing, though, it appears that the hardware's edid information is not getting read (ddcprobe returns 'edidfail').

So, could you also attach your /var/log/Xorg.0.log, and the (binary) output of get-edid (from the read-edid package)?

Booting with the i386 version of the LiveCD (required because of 1386 limitation to read-edid) was fine - correct screen res detected, nv driver installed, progress bar during boot. All the problems I've seen have been in the 64-bit LiveCD. Here's the output of get-edid:

get-edid: get-edid version 1.4.1

Running up-to-date Hardy, just installed nVidia proprietary drivers to test bug #95444 and realised that I hadn't tested this bug for ages.

I had a successful resume from suspend while using the nVidia's proprietary drivers on my Vaio SZ650, so I guess this bug is fixed.

Per a decision made by the Ubuntu Kernel Team, bugs will longer be assigned to the ubuntu-kernel-team in Launchpad as part of the bug triage process. The ubuntu-kernel-team is being unassigned from this bug report. Refer to https://wiki.ubuntu.com/KernelTeamBugPolicies for more information. Thanks.
