Description of problem: Red Hat 8.0 Installer fails to correctly identify and configure a Dell E171FP Flat Panel display. Version-Release number of selected component (if applicable): 8.0 How reproducible: Every time. Steps to Reproduce: 1. Try installing RH 8.0 from CDs on a PC with this monitor attached. Actual results: Monitor displays a black screen with the words "Cannot display this video mode." Expected results: Graphical installer should work. Settings specified during installation should work once RH is installed. Additional info: Finally got RH installed by starting installer with "linux resolution=1280x1024 skipddc", rebooting (gives same black screen and error), killing gdm, and then manually editing /etc/X11/XF86Config to add appropriate modelines. Used the procedure described at <http://www.xmission.com/~howardm/modelines.html> to calculate the entries. The installer does list the Dell E151p (a smaller predecessor?) among its known displays, but that did not work. FWIW, the redhat-config-xfree86 utility does not work either -- after choosing appropriate resolution, etc., under the Advanced section and restarting X, the same error message appears. Specs are at <http://support.ap.dell.com/docs/monitors/e171fp/en/specs.htm>. This is a fairly new, VBE/DDC compatible display. Build date is December 2002. I can post the output log(s) of ddcprobe,read-edid, XFree86 -configure, and startx, and/or the appropriate .INF files (it is a dual-boot machine with WinXP) if necessary.

This is a issue with either rhpl or kudzu.
What is the output of running /usr/sbin/ddcprobe on the installed system?
Sorry for the delay... here are the results of running /usr/sbin/ddcprobe: | Videocard DDC probe results | | Description: Intel Corporation Brookdale-G Graphics Controller | | Memory (MB): 7 | | Monitor DDC probe results | ID: DEL300f | Name: DELL E171FP | Horizontal Sync (kHZ): 30-80 | Vertical Sync (HZ): 56-76 | Width (mm): 340 | Height (mm): 270 From the monitor's specifications (see URL in comment #1 above), the scan rates and screen dimensions are correct. I know the video card has 64MB onboard, but I'm assuming the 7MB memory reported is for the monitor, not the card.
Is this better with Red Hat Linux 9?
Unfortunately I no longer have access to this particular display. I installed RH8 on a friend's new machine, which came with this monitor. If I can arrange to borrow his display for a day, I will try to find a spare machine and install RH9 on it.
