Description Laurier St.Onge 2006-09-12 08:27:39 EDT
Description of problem:

Wrong Vert rate for Samsung SyncMaster 192N...
 Is setup for 56-85 (WRONG) and should be 56-75

Horiz  30-81      Vert 56-75

Version-Release number of selected component (if applicable):

Applies to all builds when grub launches also when X windows is started.
Monitor displays an "Invalid Monitor Mode" during install and even after a 
full install during grub to X startup.

The Samsung SyncMaster 192N looks electrically identical to the 920MP(digital)
in both its Vert and Horz rates which are as stated above!

How reproducible:
Problem is MORE SEVERE under Fedora 6 Beta 2 and I do not know how to get 
around it even with Text mode setup!

Steps to Reproduce:
1. Do not enter linux skipddc or vga=0x31a
Actual results:
Grub loads (both phases) and then the monitor goes out of sync!
I have (post) edited the xorg.conf but this does not help during installs!

Expected results:

Please attach your Xorg.0.log.

Fedora Core 5 and Fedora Core 6 are, as we're sure you've noticed, no longer
test releases. We're cleaning up the bug database and making sure important bug
reports filed against these test releases don't get lost. It would be helpful if
you could test this issue with a released version of Fedora or with the latest
development / test release. Thanks for your help and for your patience.

[This is a bulk message for all open FC5/FC6 test release bugs. I'm adding
myself to the CC list for each bug, so I'll see any comments you make after this
and do my best to make sure every issue gets proper attention.]
Comment 4 Matěj Cepl 2007-07-12 10:47:06 EDT
Even after almost three months there has been no activity on these bugs, so we
consider them obsolete and they are being closed as INSUFFICIENT_DATA.

Please, if you are able to reproduce this bug on currently supported (FC6 and
F7) non-test distribution, or if there is any other reason why this bug should
be kept alive, please, reopen, change the product to something more recent and
add an additional information to the comment of such bug.

Thank you very much.

Comment 6 Matěj Cepl 2007-07-13 06:32:09 EDT
Confirmation, that this bug was reproduced (with new /var/log/Xorg.0.log and
/etc/X11/xorg.conf) either with FC6 or F7 (or Rawhide, if you wish).
