Using development modesetting driver it is possible to get the correct
resolution however rather than displaying the screen to scale the screen still

I am sorry, but we cannot work on the basis of information somewhere on the web.
Could you please, do it once more here. Please, attach your X server config file
(/etc/X11/xorg.conf) and X server log file (/var/log/Xorg.*.log) to the bug
report as individual uncompressed file attachments using the bugzilla file
attachment link below.

Could you please also try to run without any /etc/X11/xorg.conf whatsoever and
let X11 autodetect your display and video card? Attach to this bug
/var/log/Xorg.0.log from this attempt as well, please.

We will review this issue again once you've had a chance to attach this information.

Thanks in advance.

Actually, the URL mentioned below seems to be non-reponsive, so I cannot even
attach the information myself. Could you please attach the files required in
comment 1? Unless you respond in two weeks (the comment 1 is already half a year
old) I will have to close this bug as INSUFFICIENT_DATA.
Comment 3 Matt Darcy 2007-07-04 05:05:16 EDT
The URL is dead as a lot of time has passed and only one or two guys seemed 
interested in progressing this forward/accepting new info on it. 

I am happy to regnerate and provide the logs for this bug if you feel it a 
worth while bug to be worked on / resolved.
Comment 4 Matěj Cepl 2007-07-04 09:58:39 EDT
If you can reproduce this bu on supported distro (which includes FC6 of course)
then we are certainly very interested in any information on this bug. See the
instructions in comment 1 about what we need. Thank you very much.
Comment 5 Matěj Cepl 2007-08-11 16:26:46 EDT
No information requested was provided, so I close this bug as INSUFFICIENT_DATA.
Reporter, if you could, please, reopen with additional information.
