Talk:Problem with display remaining black after resume
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...
