Red Hat Bugzilla – Bug 154172
when ddcprobe fails, s-c-display always sets SVGA hsync & vsync
Last modified: 2007-11-30 17:11:03 EST
Description of problem:
I have Dell Latitude CPx J650GT and configured LCD Panel 1024x768 in anaconda.
When I starting system-config-display, ddcprobe fails and rhpl.xhwstate sets
monitor refresh at hsync=31.5-37.9 vsync=50-70. Because of this I have only two
choices for display resolution: 640x480 and 800x600, regardless of xorg.conf
configured to 1024x768.
If I select "LCD Panel 1024x768" in "Monitor" dialod and press OK, then
"Resolution" combobox allows me to select 1024x768. But this choice disappears
when I restarting system-config-display again.
IMO it such cases (if ddcprobe fails and xorg.xonf doesn't specify HorizSync and
VertRefresh explicitly) it would be better to get monitor`s hsync and vsync from
MonitorsDB, rather than set SVGA refresh values.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.Connect monitor that doesn`t work with ddcprobe but supports 1024x768
3.Try to set 1024x768 mode
There are no choice for 1024x768
1024x768 option in Resolution combobox
