[XFree86] LCD monitor: X works in Mandrake, but not in Redhat

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hola!

I have an NEC Multisync LCD1765.  I have not been able to get this monitor
to work with RH9.  I tried Mandrake 9.0 and the monitor worked without
problems.  I tried Mandy for awhile, but I really want to go back to Redhat
if possible.

I have tried to merge the working XF86Config files from M9 into the RH9
version without success.

My attention is currently focused on the horizontal and vertical sync rates.
If I enable the Redhat settings at 60Hz and 60Hz, there are no errors, but
the monitor reports "No signal found- going to sleep".   I am currently
booting to a prompt, so I can use CTRL-ALT-BKSPC to log out back to the
prompt.  When I return to the prompt, the screen is full of the typical
messages one gets when logging out of an x server to a prompt.  If I enable
the Mandrake settings (by commenting out the appropriate set of values), I
get the following errors:

(EE) VESA(0): No matching modes
(EE) Screen(s) found, no none have a usable configuration

Fatal server error:
no screens found.

My Frankenstien XF86Config file is enclosed.  I know somebody out there has
the answer or a really good hunch.  All commnets and suggestions
appreciated.  Lenard, your suggestions will be wasted on me, since I am
using a Microsoft newreader until I can get Redhat working or go back to
Mandrake.

Thanks, all!
Danny
