I also have the same problem. I am running intrepid alpha6 64bit, and nvidia driver 177. Im am using an Asus nvidia EN9500GT PCI-E discrete graphics card. My monitor is a Hanns.G HG281D LCD panel with HDMI and D-SUB inputs. The graphics card has dvi, hdmi, and d-sub outputs. My monitor only goes to sleep properly when I use the dsub connection. When I connect my monitor to the HDMI or DVI ouputs of the graphics card, the monitor does not go to sleep properly. Instead, the monitor shows a "No Signal Input" message, but I guess it's not a complete loss of signal, because the monitor does not go to sleep. If I disconnect the cable or turn off the computer then the monitor goes to sleep. I have tried "xset dpms force standby/suspend/off" and they all have the same effect (monitor's own "signal loss" message screen, but monitor never actually goes to sleep).
Some interesting points: Using the "nv" driver does not have this problem (sleep works properly over both DVI and HDMI connection). Using a different discrete graphics card (EVGA nvidia 8400GS) I don't have this problem with either "nv" or nvidia drivers. I am not using twinview or xinerama, just a single connection to a single monitor. -- monitors wont go to sleep https://bugs.launchpad.net/bugs/273484 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
