Comment # 8 on bug 1009932 from Roger Price

(In reply to Ronny Peine from comment #7)

Hello Ronny, here is the test report:

1. I checked that screen saver was in state "Disable Screen Saver" and killed
xscreensaver.

2. In an xfce terminal I repeatedly entered the command "xset dpms force
suspend".

3. The first three attempts produced the same result as force standby: Both
monitors blank for 1 second and then the previous display returns to both
monitors without any action by me.

4. Fourth attempt: both monitors go blank with blue power indicator.  DP-2 (2nd
monitor) returns with its previous display.  DP-1 (1st monitor) stays blank.  
Moving the mouse has no effect on DP-1, it stays blank.

5. I rebooted the machine, and killed xscreensaver.

6. In an xfce terminal I repeatedly entered the command "xset dpms force
suspend".

7. The first 12 attempts produced the same result as force standby

8. 13th attempt: the monitors blanked for 10 seconds before both diplays
resume.

9. The next 17 attempts produced the same result as force standby

10. 31st attempt: the monitors blanked for 10 seconds before both diplays
resume.

11. At least 20 further attempts produced the same result as force standby.

12. (Same as 4 above) Both monitors go blank with blue power indicator.  I do
not touch the mouse.  After about 10 seconds DP-2 (2nd monitor) returns with
its previous display.  DP-1 (1st monitor) stays blank.  I now move the mouse -
this has no effect on DP-1, it stays blank.  I can see the mouse movement and
type into DP-2 but DP-1 cannot be used.

Best Regards, Roger
