Description Bill D 2008-03-02 19:10:27 UTC
I have an ASUS P5E-VM motherboard and can not get a display working with the intel drivers and the HDMI (or the HDMI/DVI) output.

Monitors:

Cheepo no-name 1024x768 flat screen with VGA input.
Sony television set - very big CRT with HDMI input.
Gateway 24 inch monitor 1920x1200 with DVI input.

Software:
Gentoo, latest git kernel, Xorg 7.3, xorg-server-1.4.0.90-r3, latest git intel drivers xf86-video-intel. (same results with stable software)

I am guessing it is probably a software driver problem with the intel drivers (or perhaps a bad chipset)  Everything works great when I put an nvidia video card into the system to replace the on-board video.

Here is what I have so far:

BOOT/POST/Boot Linux:
VGA:      good
HDMI:     good
HDMI/DVI: good

X (or startx) vesa drivers (limited resolution):
VGA:      good
HDMI:     good
HDMI/DVI: good

X (or startx) intel drivers:
VGA:      good
HDMI:     black screen
HDMI/DVI: black screen

X (or startx)intel drivers, 2 monitors hooked up:
           Hi-Def:          VGA:
HDMI:      black screen     black screen (and a complaint about video frequency)
HDMI/DVI:  black screen     an X display

If stuck on a black screen some cases control-alt-backspace got back to text mode, sometimes not, but I could blind type the "reboot" command so it is not a complete lock up.  I am watching bug #13968 which sounds like a similar problem.

Bill, thanks for the clear report. But how do you think this different with #14787?
Comment 5 Bill D 2008-03-03 19:21:53 UTC
The other bug appears to imply that the HDMI connection works and that the problem appears when using the HDMI to DVI dongle.

That is not my experience.  When connected to the sony television I have worse results (no picture on the tv or on the vga).  This (speculation) could be because the sony television appears to want a resolution of 1920 x 540 -- 1080i ??

I could post log files from the television configuration, but I did not want to confuse the issue from the begining and am really more interested in using this system with the gateway 24 inch monitor at 1920 x 1200.

Could you try the latest git?

No difference with the latest driver -- I will attach a log file.  I tried with the 24 inch gateway monitor connected through the HDMI->DVI connector and also with the no-name VGA monitor on the VGA port.  Got an X screen on the VGA only.

if you mean bug# 13968, I didn't see the original bug reporter - Kevin DeKorte reort using HDMI fine. He is trying to connect it to a DVI monitor, too. Someone else reported direct HDMI works on his machine...

Bill, I've retitled the bug and mark it as dup of bug# 13968. For the direct-connection-to-HDMI-TV issue, please open a new bug, so that it won't confuse this bug report then. thanks.
