Bug Description
Binary package hint: linux-source
I am running the Alpha-4 release of 8.10 (the same behavior was observed in 7.10 and Alpha-3 release of 8.10) on my sony vaio vgn sz483n laptop. It has a selection switch to toggle between speed and stamina mode.
Suspend to RAM works like a charm when I select the stamina mode. But when I select the speed switch (which uses the nvidia graphics card) suspend to RAM does not work. The machine suspends properly and the power light becomes orange as expected. When I press any key it also looks like it resumes but the LCD screen remains blank.
I am running the open source "nv" drivers. I have tried various things including passing agp=off to the boot options and passing various quirk flags to the pm-suspend script. None of them worked unfortunately :(
I am attaching outputs of various commands.
Please let me know if you need any more information or if you need me to try out something.

Update: After installing to the hard disk, using the workarounds suggested in https:/ /help.ubuntu. com/community/ NvidiaLaptopBin aryDriverSuspen d hibernate works with Ubuntu 7.10
To get suspend to RAM to work I needed to compile the 2.6.24 kernel and install it. Once this is done suspend to RAM works but the wifi drivers and the alsa drivers don't work :(
I suspect once Hardy 8.04 is out (with the latest 2.6.24 kernel) this problem will be fixed. Therefore this bug can be closed.
