Comment 1 Sitsofe Wheeler 2005-01-05 17:22:28 UTC
Sounds related to bug #130604 . Presumably 1280x720 isn't displayed to you by system-config-display and thus you were unable to select it as the deafult at install time?
Comment 2 Evan Patey 2005-01-06 03:27:42 UTC
yes this is correct. however, the manual modeline should preclude this condition.
Comment 3 Sitsofe Wheeler 2005-01-06 15:28:46 UTC
Ah I think I see what you are saying now: Actual results: Even with custom xorg.conf (with custom modeline) 1280x720 is not available. Expected results: With custom xorg.conf 1280x720 to be available. Anyway I'd recommend attaching your /var/log/Xorg.0.log because that shows why various choices are refused.
Comment 4 Evan Patey 2005-01-06 15:44:49 UTC
Created attachment 109425 [details] Xorg log file showing resolution details Please read the sections that show the widescreen resolution failing and advise on any changes to xorg.conf.
Comment 5 Sitsofe Wheeler 2005-01-06 16:12:21 UTC
NOTE: I'm not a xorg expert. Xorg said it couldn't do 1280x720 because the hsync was out of range for your monitor. Why this is so I don't know - maybe your modeline was wrong. You may get a better answer than any I can give by asking on the fedora-list mailing list (http://www.redhat.com/mailman/listinfo/fedora-list ).
Comment 6 Evan Patey 2005-01-07 00:03:33 UTC
How do I get the HSynch in range? Which number(s) in the modeline do I need to change? Please advise. Also... there is still a defect in the way the modes are not reported in the GUI.
Comment 7 Evan Patey 2005-01-23 02:55:39 UTC
I finally have widscreen resolution. Here's what I did: 1. Downloaded AMD64 driver from ATI (brand new release) 2. Installed driver. Config'd driver 3. Switch to DVI output on my vid card 4. Modified XF86Config. The file is attached. Please notify redhat engineers.
Comment 8 Evan Patey 2005-01-23 02:58:09 UTC
Created attachment 110098 [details] XF86Config It was a pain, but I got it working using this file on my Syntax Olevia.
Comment 9 Mike A. Harris 2005-02-08 03:27:31 UTC
*** This is an automated comment update *** The X11 implementation included with Fedora Core 2 and 3, is "X.Org X11" provided by the X.Org project located at "http://www.x.org". XFree86 is no longer included in Fedora Core. To ensure faster review and investigation of X related Fedora Core bug reports, please be sure to file the bug against the correct component of "xorg-x11" in the future. Thanks in advance. Reassigning several bugs from XFree86 component to proper xorg-x11 component ...
Comment 10 Mike A. Harris 2005-02-11 21:35:07 UTC
The X server does not have modelines for widescreen resolutions built in, so you currently have to hand add custom modelines to the config file if you have a display with a native resolution that the X server does not have built in defaults for. Just to be clear, this is not a video driver or X server bug, and you do not need to use the unsupported ATI proprietary video driver. You can use the "gtf" utility to generate a modeline for your display, and then paste it into the appropriate part of the xorg.conf config file. It is recommended that once you've generated a working modeline with the "gtf" utility, or set of modelines in different refresh rates, this should be submitted to X.Org as a request for enhancement, in the X.Org bugzilla located at: http://bugs.freedesktop.org in the "xorg" component. Once you've filed your RFE in X.Org bugzilla, please paste the URL here, and we will track the issue, and consider adding the changes to future updates. Thanks in advance.
Comment 11 Mike A. Harris 2005-02-11 21:35:42 UTC
Setting status to NEEDINFO, awaiting upstream bug URL for tracking.
Comment 12 Mike A. Harris 2005-04-15 14:52:15 UTC
Please file a bug report upstream to X.Org as requested above and paste the URL here if you prefer Red Hat to track this issue. Thanks in advance.
Comment 13 Mike A. Harris 2005-04-20 16:39:40 UTC
# 1280x720 @ 60.00 Hz (GTF) hsync: 44.76 kHz; pclk: 74.48 MHz Modeline "1280x720_60.00" 74.48 1280 1336 1472 1664 720 721 724 746 -HSync +Vsync This is a GTF mode. If you could test that and provide feedback, that would be appreciated. We can add it to the extramodes if it works.
Comment 14 Mike A. Harris 2005-05-19 00:59:41 UTC
In comment #13 above, I provided a modeline generated with the "gtf" utility that comes with Xorg. The timing differs slightly from the modeline provided in the initial report, however modelines calculated using the VESA GTF standard are always prefered over modelines generated by alternative means. Before we consider modifying the X server to include this modeline, we need it to be tested. If someone is still interested in seeing these changes added to the distribution, please remove manually supplied modelines from the X config file, and replace it with the following: Modeline "1280x720" 74.48 1280 1336 1472 1664 720 721 724 746 -HSync +Vsync Add "1280x720" to the "Modes" list in the screen section, and test it. Provide feedback as to wether it works or not, and either way - attach your X server log file and config file to the report as individual uncompressed file attachments for review, then set the bug status back to "REOPENED". Due to lack of response in over 3 weeks however, I'm setting the status to "WONTFIX", as we require the above tests to be performed first, and have direct feedback from someone who has tested them before we will consider adding them to the OS by default. Once the tests are performed, and status updated, feel free to "REOPEN" if you still want us to track the problem. Thanks in advance.
