This means X, by default, is using a display mode that doesn't work. Obvious, I know... It's important to note that the default display mode is the first entry in the Modes section for the selected depth in the selected display. Wait, that's not exactly right. It's the first *working* entry. But in your case, XFree86 and your graphics card and/or monitor disagree on the meaning of the word "working". > Pressing it a couple more times, produces the perfect resolution on my LCD > screen. Tell us exactly how many times. And you're using CTRL+ALT+MINUS, right? That steps right-to-left through the Modes list. CTRL+ALT+PLUS goes left-to-right. (Is this always true?) As I so-clumsily stated above, nonworking modes are skipped. > The monitor reports this as 1280x1024, 80kHz, 75Hz.

If XFree86 doesn't default to it even though it's first in the list, then it doesn't think it works. > Shuttle SK41G with ProSavage chipset > IIyama 4315 LCD monitor (using analogue input) - its manual lists a > 1280x1024, 79.976kHz, 75.025Hz, 135MHZ mode > # Option "XkbVariant" "nodeadkeys" I've always wondered what this meant...

I guess it knows how to handle this resolution at both 60 Hz and 75 Hz. Above it also lists 85 Hz and 100 Hz, but apparently X feels that even though your card might be able to handle those, your monitor can't.

[... other stuff ...] This must be the mode it starts with. Can someone verify this by double- checking the log? By checking the mode table logged above, I see this is 1280x1024. It's probably "1280x1024-75" because that's what's first in your list and because I saw no log message saying it had been rejected. > (--) SAVAGE(0): Chose mode 111 at 75Hz. 111: "640x480" (you must have used CTRL+ALT+MINUS) > (--) SAVAGE(0): Chose mode 114 at 75Hz. 114: "800x600" > (--) SAVAGE(0): Chose mode 117 at 75Hz. 117: "1024x768" > (--) SAVAGE(0): No suitable BIOS mode found for 1152x864 108MHz. "1152x864" isn't listed in the BIOS mode table above, so remove it from your Modes list. > (--) SAVAGE(0): Chose mode 14f at 60Hz. 14f: "1280x960" (you might want to remove this because it's 60 Hz) > (--) SAVAGE(0): Chose mode 11a at 75Hz. 11a: "1280x1024" What happens when you press CTRL+ALT+MINUS one more time at this point? Does the screen change? It should 'flip' from "1280x1024" to "1280x1024-75", which, as far as I can tell, are identical. It appears you settled on 1280x1024, 75 Hz after all. Weeeird, this brings us to your problem. The mode doesn't work the first time but works after you select something else and then come back. First try removing "1280x1024-75" (it's redundant), "1152x864" (it's not supported), and "1280x960" (it's not 75 Hz). I don't expect that to fix anything, but hey, you don't need those modes anyhow. And we'll take it from there. -- Andy Goth | [EMAIL PROTECTED] | http://ioioio.net/ End communication. _______________________________________________ XFree86 mailing list [EMAIL PROTECTED] http://XFree86.Org/mailman/listinfo/xfree86
