From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:0.9.9) Gecko/20020513 Description of problem: I'm having trouble configuring X to run with my display hardware when using the digital interface. I'm using: Eizo L565A LCD display (has both analog and digital ports) Interpeed GeForce2 MX/400 viceo card (DVI-I port, 32Mb RAM) Thus far I've only been able to make them run in analog mode. When I do that, I get a nice 1280x1024 resolution, Hsync at 80kHz, Vsync at 75Hz. It works fine, but I'd like to be able to take advantage of the digital interface. When I try that, however, nothing works. According to the manual, the specs for the screen in digital mode are Hsync 31.5-64kHz Vsync 60Hz, 70Hz When I enter these in Xconfigurator's custom mode (the display is not automatically recognized) and do the test, the display reports a diagnostic saying that the Vsync is out of spec at 41.6Hz, which is awfully weird. I tried setting the Vsync paramenter in Xconfigurator to 60 (rather than 60-70), and got a blank (dark) screen, but no diagnostic. Since the hardware works together just fine in analog mode, this points to one or more of: Digital video processing in the display Digital video processing in the video card The DVI-D cable I'm using X configuration In fact, I doubt if X even cares whether the connection between the video card and the screen is digital, but it does seem like some strange interaction between the X and the card could still have something to do with the problem. The display allegedly supports DDC, so it seems possible that X is getting messed up there -- I heard that this sometimes fails. Unfortunately I don't know much about display systems, so I'm hoping that you will have some suggestions that will either fix the problem or allow me to diagnose which component is the culprit. PS The OS installation is a clean install, out-of-the-box Linux-only workstation class, brought up to date with all subsequently released patches (except the 2.4.18-5 kernel upgrade). Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: Given identical hardware, simply use the digital interfaces and run Xconfigurator. It should fail on the test. But of course I have no idea if it reproduces using hardware other than my own. Additional info:
