You need to enter the hsync and vrefresh ranges for your monitor in the monitor section of your config file. Also if you are running xfree86 from cvs you can try the "monitorlayout" option. see the radeon and XF86Config man pages for more info. Alex -------------------------- I just installed XFree 4.3.0 as part of a Mandrake 9.2 install. I'm using a Hyundai L70A LCD panel connected via DVI to my ATI All In Wonder 7500. The native resolution of the panel is 1280x1024. XFree starts and runs fine but does not allow the use of any resolutions above 640x480. Looking through the logs seems to indicate that the monitor is not providing any DDC data, so the X server refuses to use any modes above 640x480. I did some web/newsgroup searching and saw a few reports of similar problems but no solutions. I've tried various combinations of Option "DDCMode", "NoDDC", "IgnoreEDID", "CrtScreen", and "crt_screen" which all failed to fix the problem. Any suggestions? Here are the relevant lines from the log: (II) RADEON(0): Primary Display == Type 3 (II) Loading sub module "ddc" (II) LoadModule: "ddc" (II) Loading /usr/X11R6/lib/modules/libddc.a (II) Module ddc: vendor="The XFree86 Project" compiled for 4.3.0, module version = 1.0.0 ABI class: XFree86 Video Driver, version 0.6 (II) Loading sub module "i2c" (II) LoadModule: "i2c" (II) Loading /usr/X11R6/lib/modules/libi2c.a (II) Module i2c: vendor="The XFree86 Project" compiled for 4.3.0, module version = 1.2.0 ABI class: XFree86 Video Driver, version 0.6 (II) RADEON(0): PLL parameters: rf=2700 rd=12 min=20000 max=35000; xclk=18000 (==) RADEON(0): Using gamma correction (1.0, 1.0, 1.0) (II) RADEON(0): Validating modes on Primary head (DDCType: 0) --------- (II) RADEON(0): Total number of valid DDC mode(s) found: 0 (WW) RADEON(0): Mode 1280x1024 is out of range.
