Description of problem:
During the install of FC5T1 my video card and monitor are detected properly. When firstboot comes up and I am prompted to select the resolution and color depth the proper resoltion is not listed. I have a Revolution IV video card and a SGI 1600sw LCD monitor. The resolutions for this monitor are 800x512 and 1600x1024. I can attach a working xorg.conf file if it would help.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. install fc5t1
2. the correct resoultion is not there
Actual Results: The screen does not appear correctly because the wrong resolution is used.
Expected Results: I should be able to select the proper resolution, which should automatically write the correct settings to xorg.conf so X will work correctly.
If you edit /etc/X11/xorg.conf to have the correct resolutions does it work? If
not please attach /var/log/Xorg.0.log as an uncompressed attachment. The
modelines are in rhpxl extramodes.
If I add the modelines by hand, or copy my old working xorg.conf to the system
Xwindows works fine. The modelines might be in rhpxl but firstboot did not show
800x512 or 1600x1024 as a resolution I could select.
Here are the working modelines:
ModeLine "1600x1024d32" 103.125 1600 1600 1656 1664 1024 1024 1029 1030 HSkew 7
ModeLine "1600x1024d16" 103.125 1600 1600 1656 1664 1024 1024 1029 1030 HSkew 5
ModeLine "1600x1024d08" 103.125 1600 1600 1656 1664 1024 1024 1029 1030 HSkew 1
ModeLine "800x512d32" 54.375 800 800 840 848 512 512 514 515 HSkew 7 DoubleScan
ModeLine "800x512d16" 54.375 800 800 840 848 512 512 514 515 HSkew 5 DoubleScan
ModeLine "800x512d08" 54.375 800 800 840 848 512 512 514 515 HSkew 1 DoubleScan
This looks similar to 174686
This bug is for s-c-d not listing 800x512 and 1600x1024 as valid resolutions for
my monitor when firstboot calls s-c-d (just after the intial install is complete).
174686 happens after the install is complete. S-c-d crashes when I try to
system-config-display still not list 800x512 and 1600x1024 as proper resoultions
for my monitor.
system-config-display-1.0.36-1 still does not list 800x512 and 1600x1024 as
proper resoultions for my monitor (a SGI 1600SW).
