I worked with a person at Red Hat on this problem this A.M. trying to
start XFree86 version 4.0.3, with no success.
During installation, the Red Hat installation program found the Radeon AGP
SDR card and Gateway FPD1500 monitor, and an imperfect X screen desktop
(screen with some distortion around text items) could be seen. However,
after the initial install program, attempts to run XFree86 failed with a
blank screen. We ran Xconfigurator, and during all configuration tests,
XFree86 yields a blank screen also. The Red Hat rep. checked the horizonal
sync and vertical sync. of the FPD1500 monitor and gave me slightly
corrected values to try, as well as double-checking that the color was 16
bit and the screen resolution 1024x768. These did not solve the problem.
We also double-checked that Option "nodri" was set (it was).
On running modprobe -d radeon, modprobe failed with the error
message "cannot initialize agpgart module". On running modprobe -d
agpgart does not give an error message, and subsequent calls to modprobe -
d radeon also did not cause an error. After the modprobes, we again tried
to start X, again without success.
Steps to Reproduce:
1.Use either installation routine or Xconfigurator to configure card
2.In Xconfigurator, do not get an acceptable configuration, with
3.Otherwise, type startx. About half of the time I can get back to the
command-line using <Ctrl>-<Alt>-<Backspace>, the other half of the time
only a reboot will bring back the screen.
Actual Results: Blank screen with screen status light changed to yellow
(normally power save or computer off status). If in Xconfigurator, the
screen sometimes will return with the message that the configuration is
not good. As mentioned above, when trying startx, about half of the time
I can get back to the command-line using <Ctrl>-<Alt>-<Backspace>, the
other hold of the time it's locked up totally.
Thank you in advance.
You should not use modprobe at all for any video card. XFree86 will
automatically modprobe any kernel DRM modules on its own, as well as
agpgart. The Radeon 3D is not supported at all, and so any radeon.o
kernel module should _never_ be loaded.
Is this a Radeon VE card by chance? Please supply your XF86Config-4
and X server logs as file attachments using the "Create a new attachment"
link below. Also, I will need the output of "lspci -v" as well as
"lspci -vn" to analyze the PCI ID's.

Hi. I believe that I have attached the information that you have requested.
To the best of my knowledge, the card is a Radeon AGP QD. Please let me know
if you require more or different information, and thank you again for looking
P.S. The file really is XFree86Config-4. Sorry for the typo on the label
Another customer is having a similar problem. The primary ID is 0x1002 (ATI)
0x5144 (Radeon), subsystem ID is 0538. Xconfigurator works, detects things
correctly, displays a black screen on testing. He has an SPD(FPD?)1800
flat-panel display hooked up to the DVI port.
Does XFree86 4.2.0 in Red Hat Linux 7.3 still exhibit this problem?
Closing CURRENTRELEASE. If the problem persists in Red Hat Linux 7.3
with all erratum applied, feel free to reopen and I'll look into this
