Comment 47 for bug 935778

To find the problem I attached the file /var/log/pm-suspend.log. I also found out, that this machine is not known by s2ram, although suspend works except the screen brightness.

# /usr/sbin/s2ram -n
  Machine unknown
  This machine can be identified by:
      sys_vendor = "TOSHIBA"
      sys_product = "TECRA R850"
      sys_version = "PT525E-00D00SS4"
      bios_version = "Version 3.00 "
  See for details.

By the way to things:
1) Because I have 8GB RAM and an SSD Harddrive I have no SWAP Partition, but by my side this shouldn't be a problem.

2) As described here ( I tried to edit /proc/acpi/toshiba/lcd manually using the following command:
  # sudo echo "brightness:4" > /proc/acpi/toshiba/lcd
But also with sudo rights I can not write to the file, the error message says "bash: /proc/acpi/toshiba/lcd: Keine Berechtigung" even tough I should have rights for sudo
