I have a mach64-GX that keeps trying to overdrive my display. I've set a modeline of 640x480 at 60hz and 29.8khz. When I run it, my display complains that I'm sending it 239Hz and 118K.
This is a factor of 4 difference in both frequencies. What's likely to be happening here? I can very occasionally get it to display, but it's monochrome and stretched. I wouldn't be surprised if the stretch was a factor of 4 actually. It really sounds like a problem with the clock, and when I check the log, it's full of modes eliminated for a bad clock. For example: [ 5318.178] (--) MACH64(0): Reference clock 157.5/11 (14.318) MHz. [ 5318.179] (II) MACH64(0): Monitor0: Using hsync range of 30.00-85.00 kHz [ 5318.179] (II) MACH64(0): Monitor0: Using vrefresh range of 50.00-160.00 Hz [ 5318.180] (II) MACH64(0): Clock range: 9.00 to 80.00 MHz [ 5318.180] (II) MACH64(0): Not using mode "1024x768@75" (bad mode clock/interlace/doublescan) [ 5318.180] (II) MACH64(0): Not using default mode "320x175" (bad mode clock/interlace/doublescan) [ 5318.185] (II) MACH64(0): Not using default mode "320x200" (bad mode clock/interlace/doublescan) [ 5318.185] (II) MACH64(0): Not using default mode "360x200" (bad mode clock/interlace/doublescan) ... [ 5318.239] (**) MACH64(0): *Mode "640x480@60": 23.9 MHz, 29.8 kHz, 60.0 Hz [ 5318.239] (II) MACH64(0): Modeline "640x480@60"x60.0 23.86 640 656 720 800 480 481 484 497 -hsync +vsync (29.8 kHz) I know there's an option to actually set the reference clock, but the documentation says it's for non-intel platforms, so I'm disinclined to play with it unless encouraged to do so. FWIW the entire log can be found here: http://pastebin.ca/2138566 And my xorg.conf is here: http://pastebin.ca/2138568 I know this is an old machine, but that's all the more reason why I'd really like to have 2d acceleration on it. VESA is unbearably slow. Any thoughts, advice, hints, tips, or pointers would be appreciated. _______________________________________________ [email protected]: X.Org support Archives: http://lists.freedesktop.org/archives/xorg Info: http://lists.x.org/mailman/listinfo/xorg Your subscription address: [email protected]
