Thanks Alex adding the modelines worked. I tried Beso's suggestion first without success. I have 2 follow up questions, 1) What changed in 7.3 that caused this issue? 2) How do I generate Mode lines so I can update 1280x1024 and 1024x768 at a higher frequency than the 60hz currently posted in xrandr? Thanks again for your help.. Just for completeness Beso's suggestion i don't see anything that seems like a monitor props scan. i neither don't see things that seem odd in your xorg.conf. i'd only suggest you to add the following to it: <blockquote style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;" class="gmail_quote"> Section "Modes" Identifier "Modes[0]" EndSection</blockquote><div><blockquote style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;" class="gmail_quote"> </blockquote></div><blockquote style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;" class="gmail_quote">Section "Extensions" Option "DAMAGE" "true" Option "RENDER" "true" Option "Composite" "Enable" EndSection </blockquote> the following to the screen section:<div class="Ih2E3d"> <blockquote> Device "** ATI Radeon (generic) [radeon]" Monitor "IBM P70" </blockquote> </div>the first options should set up a mode section, the extensions would enable damage, rendering and compositing (this would increase your overall xorg experience), while the addons in the screen section should tell xorg that that screen has the defaults for the monitor ibm p70 and of the device indicated above. so it should set the resolution to the first available in the 16bit section of the screen section (since your screen is set to 16bit by default). -- <div class="gmail_quote">On Sun, Mar 23, 2008 at 10:46 AM, Alex Deucher <<a href="mailto:alexdeucher@gmail.com">alexdeucher@gmail.com</a>> wrote: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"><div class="Ih2E3d">On Sun, Mar 23, 2008 at 7:55 AM, Greg Treantos <<a href="mailto:gtreanto@gmail.com">gtreanto@gmail.com</a>> wrote: > I am running a Gentoo system and after upgrading to x11 7.3 now when I issue > startx, xwindows starts with a screen resolution of 1152x768 54.8hz.

Thanks > </div><div class="Ih2E3d">(II) RADEON(0): Found color CRT connected to primary DAC </div>The driver is not able to get an edid from the monitor so it doesn't know what modes the monitor supports. At this point the server attempts to (rather poorly) pick a mode within the sync ranges of your monitor as specified in your monitor section. Ajax has attempted to fix up the mode selection logic in these cases in newer X servers. For now you have to specify a preferred mode and possibly some modelines, depending on the referesh rate you want. See below.
