Description of problem: Hardware: Dell Optiplex GX270 with Nvidia Geforce 4 MX and Dell 1901FP monitor connected via DVI. Monitor never goes into power saving mode which means the back lights will burn out much sooner. XFree86 config file generated with redhat-config-xfree86 command. Xscreensaver set to do power management and shutoff the screen. The command "xset dpms force off" blanks the screen but the monitor does not go into power saving mode. Nor does the screensaver put the monitor in power saving mode. This was working on previos machine: Dell Optiplex GX260 with ATI Radeon VE connected to a Dell 1801FP using the ati driver. So, I think there is a problem in the "nv" driver. Version-Release number of selected component (if applicable): How reproducible: Very Steps to Reproduce: 1. RHEL 3 with Nvidia card and "nv" xfree driver should do it. 2. 3. Actual results: Expected results: Additional info:
The XFree86 4.3.0 "nv" driver supports DPMS only on CRT displays, and does not support DPMS on DFP panels connected via DVI. As such, this is a lack of feature in the driver rather than a bug. Since the hardware specifications for Nvidia hardware are not available to Red Hat nor the open source community, unfortunately we do not have any way of adding this feature to the driver, other than to wait for Nvidia to provide patches under an open source MIT/X11 style license to Red Hat or to the community which implement this functionality. If such patches become available in the future, we may review them and consider reopening this request. Updating bug report summary, and closing as 'WONTFIX'.
