Bug Description

Binary package hint: lcdproc

During S3 suspend LCDd should be stopped and restarted on resume.

This has two possitive effects:
 1) the display is dark indicating the computer is asleep
 2) you can unloasd the modules responsible for LCD device (they sometimes don't play well with suspend/resume)

Attached is a proposed simple script which stops LCDd on suspend and restarts it on resume. It should be installed as /usr/lib/pm-utils/sleep.d/50LCDd

Would it help if I made a debdiff of this? It's pretty simple. Maybe that would get it sponsored. i independently came up with this same solution on my mythbuntu frontend.

Sorry, I work mostly on Debian side, and I didn't see this bug report. I'll implement your proposal on Debian. Ubuntu will get the fix soon after.

All the best

This bug was fixed in the package lcdproc - 0.5.7-2

---------------
lcdproc (0.5.7-2) unstable; urgency=medium

  * stop/start LCDd on suspend/wakeup (LP: #365474)
  * provide and use permanent symlink for imon device file (LP: #1186569)
    This requires udev for Linux.
  * control:
    + added depends on udev and libconfig-model-lcdproc-perl (>= 2.042-2)
    + added dependency on libconfig-model-perl >= 2.059 to avoid a bug
