Description Dave W. 2003-02-28 00:02:10 UTC
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.

Comment 3 Jeremy Katz 2003-03-04 17:54:48 UTC
What is the output of running /usr/sbin/ddcprobe on the installed system?

Comment 4 Dave W. 2003-03-06 18:48:36 UTC
Sorry for the delay... here are the results of running

| 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.

Comment 5 Jeremy Katz 2003-07-28 23:30:07 UTC
Is this better with Red Hat Linux 9?

Comment 6 SM 2003-08-08 21:21:32 UTC
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.
