From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7) Gecko/20040625 Description of problem: A Sony Multiscan 15sf CRT monitor will do 1024x768 @75Hz, but it has no DDC. During install and firstboot, the monitor is detected as "Unprobed monitor" and there is no opportunity to override this, nor is there a message about how to change it after installation. The screen comes up as 800x600 instead. Not allowing override of "Unprobed monitor" during install and/or firstboot is an unexpected decrease in functionality. Both the Anaconda developers and I have worked hard over the past 2 or 3 years to get the manual choice working correctly (H&V frequencies were swapped once; Dell Laptop screen choice was not clear; etc.). The FC1 and FC2 installers finally had good support for non-DDC monitors. Why was this support removed? Version-Release number of selected component (if applicable): firstboot-1.3.16-1 How reproducible: Always Steps to Reproduce: 1. Fresh graphical install from CD-ROM using CRT monitor without DDC. 2. Enter X11 configuration screen of firstboot. 3. Actual Results: During firstboot the only choice is color depth (hundreds, thousands, or millions of colors); there is no choice to override "Unprobed monitor". Expected Results: There should be a choice to override "Unprobed monitor" by choosing from the monitor database. Additional info:
If you boot the installer with the "resolution=1024x768" option and (re)install with that, does that make any difference to the final installed system?
The plan is to add a "select monitor" button to the firstboot screen, just haven't gotten there yet.
Replying to Comment #1 (Barry K Nathan): booting the installer with "linux resolution=1024x768" gets a Monitor section in /etc/X11/xorg.conf with HorizSync of 31.5 - 48.5, and a Screen section than has 1024x768 first. Thus the screen is 1024x768 @60Hz, according to "xrandr". In order to get @75Hz, then I copy from RHEL3 which has HorizSync 31.0 - 64.0 (and VertRefresh of 50.0 to 120.0 instead of 40.0 - 70.0).
In addition to the feature work one useful thing the original poster can do to get the monitor added to the database is (quoting mharris): " All you have to do, is attach Microsoft Windows .INF files supplied by the monitor manufacturer into a bugzilla bug report that requests the entries be added to the database. Feel free to attach all .INF files for all monitors of a given brand, or of as many brands as you like, and they'll all get processed simultaneously." If you could open a seperate bug against hwdata with the monitor.inf attached that would be useful.
Sony Multiscan 15sf is already in the database -- it just doesn't have DDC support and thus can't be automatically probed.
I've added a button to the firstboot screen in system-config-display for monitor detection. Will appear in rawhide shortly.
