This is in SEAWOLF! During CD/GUI/fb install, configuring X on a Dell Inspiron 7500: For all of the ATI Mobility video cards, 1280x1024 does *not* show up as an acceptable resolution, though 1400x1050 does (incorrectly). Dell ships (shipped? it isn't even a year old yet!) this laptop with a choice of 2 displays. One does 1400x1050 (and may be able to do 1280x1024), but the one I chose does 1280x1024 (and can't do 1400x1050). According to the install screens, the display is "DCC probed". Somehow, there must be a way to differentiate between these 2 displays. BTW, I chose the display based on the fact that I should be able to throw a nice big monitor on it; with 1400x1050, I didn't think that would fly very well (if at all). We did go through this on an earlier beta, but I was unable to schedule more testing in between. Sorry, "real" work interfered. I still don't know if Xconfigurator is the correct component for install-time X configuration. If not, please adjust as necessary.
I'm not sure if Xconfigurator is involved here, but I know for sure that the installer is not giving the choice of 1280x1024 with the ATI Rage Mobility chipset. The text based installer uses Xconfigurator, but the GUI does not. What is the behavior like with the text installer? Changing component to anaconda.
Running Xconfigurator manually (after the GUI install) correctly allows me to choose the Dell 1280X LCD. Should I trust that Xconfigurator invoked through the text installer will behave the same?
Yes. I think the problem is specific to the GUI installer. Will address in a future release.
Fixed in cvs. Should appear in post anaconda-7.1-5.i386.rpm builds. Thanks for your report.
