From my experience, this does not work with TP R50e.
If you want to be able to resume, you need :
- To start from a VT
- No option acpi_sleep
- to save the PCI state like:
cat /proc/bus/pci/00/02.0 > /var/cache/video.config
- Once you get back, restore it:
cat /var/cache/video.config > /proc/bus/pci/00/02.0
However, the X screen is not clean after the restore, so this is not very useable...
