2. Close lid

Expected results:

screen is switched off.

Additional info:

Can be solved by changing

/usr/share/hal/fdi/information/10freedesktop/20-video-quirk-pm-el5-ibm.fdi

In this file the X31 is not detected correctly, according to hal:

 lshal | grep system.hardware
  system.hardware.uuid = 'E47BD681-46E4-11CB-B1D0-E417DF42D093'  (string)
  system.hardware.serial = '9924KTR'  (string)
  system.hardware.version = 'ThinkPad X31'  (string)
  system.hardware.product = '26725KG'  (string)
  system.hardware.vendor = 'IBM'  (string)
  system.hardware.primary_video.product = 19545  (0x4c59)  (int)
  system.hardware.primary_video.vendor = 4098  (0x1002)  (int)

The prefix *should* be 2672, in the fdi however this prefix is defined as X40/X30.

Whatever.

After changing

      <!-- X40/X30 -->
      <match key="system.hardware.product" prefix="2672">
        <merge key="power_management.quirk.s3_bios" type="bool">true</merge>
        <merge key="power_management.quirk.s3_mode" type="bool">true</merge>
        <merge key="power_management.quirk.radeon_off" type="bool">true</merge>
      </match>

To
      <!-- X40/X30 -->
      <match key="system.hardware.product" prefix="2672">
        <merge key="power_management.quirk.dpms_suspend" type="bool">true</merge>
        <merge key="power_management.quirk.s3_bios" type="bool">true</merge>
        <merge key="power_management.quirk.s3_mode" type="bool">true</merge>
        <merge key="power_management.quirk.radeon_off" type="bool">true</merge>
      </match>

suspend works as intended.

So supposed fix is to add the dpms_suspend quirk to the 2672 prefix
