RFE: Please add 1152x864 100hz modeline
Last modified: 2007-11-30 17:10:30 EST
I have XFree86-4.0.3-5 and Xconfigurator-4.9.29-1. Installation with my Matrox G450 went fine so far (except the missing DRI but this is another problem). However, after the installation X runs only with 1152x864 75Hz although the monitor can easily run 100Hz. A quick test showed that the relevant modelines are in /etc/X11/XF86Config, but not in XF86Config-4. After I copied the modelines to XF86Config-4 my X server runs with 1152x864 100Hz. BTW, the same happens with Matrox G400 (and working DRI). Why do I have to copy the modelines manually after the installation?
Because XFree86 4 has the modelines built into the server itself. It also accepts modelines in the config file though. So if there are missing modelines in 4.x, that are important, they should be added via patching X sources rather than by us hacking Xconfigurator. This has already been requested however, and a patch applied to XFree86 4.1.0 in rawhide for 85Hz. If you'd like 100hz also, please attach the commented modeline and I will patch it into XFree86.
This is the modeline I copied from XF86Config to XF86Config-4. It works fine for me. # 1152x864 @ 100 Hz, 89.62 kHz hsync Modeline "1152x864" 137.65 1152 1184 1312 1536 864 866 885 902 -HSync -VSync Would be fine if it would be included into XFree86-4.1.0. BTW, what files do I need to upgrade to 4.1.0? Is it sufficient to install all XFree86*-4.1.0-0.8.6.i386.rpm, Mesa*-3.4.2-3.i386.rpm and Xconfigurator-4.9.31-1.i386.rpm Do I have to recompile the kernel (kernel-2.4.3-12 in the moment) to get DRI with my Matrox G450 DH working? Does there exist a document which describes the update?
This is 3 years old, and probably deprecated as well (for one, Fedora has moved to xorg). Can this be closed? -Chris Kuivenhoven
Bug can be closed (It doesn't occur in XFree86-4.3.99.902 in Suse. I had to switch to Suse because there is no retail customer version of Redhat Linux :-()
This was closed "CURRENTRELEASE" which I believe is incorrect, unless upstream added this modeline to xorg-x11 6.7.0 (which is in our current release). General purpose modelines really should be built directly into the X server, and formulated by using the VESA GTF specification. The proper place to have new modelines added to the X server directly is by filing a request for enhancement to the upstream X.Org project (or XFree86) directly. Once the request is reviewed and resolved by X.Org, the modeline will be available to all Linux distributions, without each distribution needing to manually patch their X server each OS release. In the mean time, the modeline can easily be added by hand to the X server config file as a simple workaround. Take care, TTYL
A quick check seems to show either nobody ever requested this upstream, or if they did, Xorg never added the mode to the server. I've added 1152x864@100 Hz calculated using VESA GTF to the Red Hat extramodes patch for the time being as follows: $ gtf 1152 864 100 # 1152x864 @ 100.00 Hz (GTF) hsync: 91.50 kHz; pclk: 143.47 MHz Modeline "1152x864_100.00" 143.47 1152 1232 1360 1568 864 865 868 915 -HSync +Vsync It will be in the next X server build in rawhide (1.1.1-8.fc6)
