            Bug ID: 98375
           Summary: Intel driver is ignoring DPMS monitor section
           Product: xorg
           Version: unspecified
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/intel

Xorg.log with logverbose 20

Hi.
The problem is that the intel driver seems to ignoring the:
Option "DPMS" "false"
of the associated monitor section in the xorg.conf.

Expected behavior: If a monitor has "DPMS" set to "false" the monitor should
stay powered on, even after typing "xset dpms force off"/or DPMS enabled by the
window manager.

Current behavior: The monitor is powered down.
I was also testing to put "DPMS" "false" to all monitors associated with the
intel driver - the result was the same => all monitors went sleep.

Other drivers (tested on nvidia and nouveau) honors this option and monitor
with the above option set is not turned off, while the others are.

As a side note, I can see a difference in parsing the option by the driver,
because when all intel-driven monitors are without the DPMS option, then I have
in the log:
[   147.737] (==) intel(0): DPMS enabled
[   147.737] (==) intel(1): DPMS enabled

and when I disable DPMS for monitor0, then in the log is only one line:
[   147.737] (==) intel(1): DPMS enabled

I am attaching my xorg.conf and the log with .
