Default xorg.conf results in out-of-range video signal
Last modified: 2007-11-30 17:07:39 EST
A default installation of RHEL5 Beta 2 on a Dell E521 produces an out-of-range
video signal (for a Dell 2005FPW LCD display) and blank screen during RHGB,
firstboot, and X11. Manually running systom-config-display and selecting
appropriate monitor and resolutions settings fixes the problem.

Note that the 2005FPW is connected via a KVM which does not pass DDC probe info.
This may account for the nearly blank default xorg.conf. However I'd expect a
failed probe to result in an xorg.conf with very conservative settings and,
ideally, system-config-display automatically presented to the user.

fixed by a later update.

Reporter, I am sorry, that we have left this bug unnoticed for so long, but
could you confirm please, that this bug still could be reproduced with the
latest updates of RHEL?
Reporter, could you please reply to the previous question? If you won't reply in
one month, I will have to close this bug as INSUFFICIENT_DATA. Thank you.
What, you have 6 months to respond and I only have 2? :)
RHEL 5 final appears to work correctly from a default install on my hw.
Thanks a lot for letting us know. Yes, there is no justice in the world ... :-)
