Description Sitsofe Wheeler 2006-06-17 11:06:16 EDT
Description of problem:
The monitor is not turned off during a suspend to RAM.

Version-Release number of selected component (if applicable):

How reproducible:
Every time.

Steps to Reproduce:
(as root)
1. Edit /usr/sbin/pm-suspend so that it echos "standby" instead of "mem" into
2. modprobe -r acpi_cpufreq (see Bug #195367)
3. Run pm-suspend .
Actual results:
Mointor stays on and
Stopping taks: ===========|
and a flashing '_' cursor are visible.

Expected results:
Monitor to be put into power saving mode and powersaving to be left when a
resume takes place.

Additional info:
Ubuntu Dapper does
/usr/sbin/vbetool dpms suspend
for all graphics cards by default (I guess the thining goes that other than
super old cards there is no harm in turning the monitor off twice).

FC5 is now end of life, so sadly this bug won't be fixed in this release. Is
this bug still present in FC6 or F7?
Comment 5 Sitsofe Wheeler 2007-08-30 13:07:07 EDT
Since filing this bug over a year ago the machine had its SiS graphics card
swapped away for an NVIDIA so I can't follow up on this.

Let's resolve this INSUFFICIENT_DATA.
