From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i586; en-US; rv:1.8.0.6) Gecko/20060808 Fedora/1.5.0.6-2.fc5 Firefox/1.5.0.6 pango-text Description of problem: At boot if monitor (SAMSUNG SyncMaster 701N) not attached (via KVMswitch) to the system login screen defaults to large size (1920 x 1200) and if connected it gets setup as (1400 x 1050). The native display size is 1280 x 1024 and I notice that no display sizes get specified in X11.conf anymore. Also at install the monitor was not detected correctly I had to select it from the list but this only worked after the first set of updates and I think I had to wait for the next updates before you could specify the video card. Once loged in you can set the users display size and refresh rate but it defaults at the next login to the highest available refresh rate for the given resolution. (see bug 176326) On previous installs at first boot you got the opertunity to set the maximum display size and color depth but this was not the case for FC6test2 so are we now dynomically detecting monitot capabilities at each boot and if so this will cause problems where people like me use one monitor for several systems va a KVM switch Version-Release number of selected component (if applicable): current as of 10/8/06 and apparent since FC6test2 install How reproducible: Always Steps to Reproduce: see description Actual Results: see description Expected Results: Some mechanism to fix expected monitor size at boot (it was previously done in the x11.conf file) Additional info:
Adding back the following in xorg.conf (annotates **) cures the problem. # Xorg configuration created by system-config-display Section "ServerLayout" Identifier "single head configuration" Screen 0 "Screen0" 0 0 InputDevice "Keyboard0" "CoreKeyboard" EndSection Section "InputDevice" Identifier "Keyboard0" Driver "kbd" Option "XkbModel" "pc105" Option "XkbLayout" "gb" EndSection Section "Monitor" Identifier "Monitor0" ModelName "Samsung SyncMaster 710N/177N/CX711N/CX701N" ### Comment all HorizSync and VertSync values to use DDC: HorizSync 30.0 - 81.0 VertRefresh 56.0 - 85.0 Option "dpms" EndSection Section "Device" Identifier "Videocard0" Driver "nv" EndSection Section "Screen" Identifier "Screen0" Device "Videocard0" Monitor "Monitor0" DefaultDepth 24 ** SubSection "Display" ** Viewport 0 0 ** Depth 24 ** Modes "1280x1024" ** EndSubSection EndSection
Can you attach the Xorg.0.log from a startup without the extra Display subsection?
Created attachment 135284 [details] info as requested See attachment info as requested.
Note between the iniial re-creation of the xorg.conf file and the .1 logfie and between the creations of .1 and .2 and between .3 and .4 and between .4 and .5 the system was restarted. The monitor was specified after the creation of .3 log file by running s-c-display and the resulting new xorg.conf file (4-6) being saved before restarting the system.
Well for one, you're getting the sync ranges wrong in the config file, which is assuredly giving you a much larger range of bad modes than you'd normally see: HorizSync 30.0 - 81.0 VertRefresh 56.0 - 85.0 Versus: (II) NV(0): Ranges: V min: 56 V max: 75 Hz, H min: 30 H max: 81 kHz, PixClock max 140 MHz That appears to be a bug in the MonitorsDB list though, which should be fixed in 0.187 which I just pushed. I'm definitely seeing the resolution selection bug now though, working on it.
Is this bug resolved now? Then please close it :-)
Closing as resolved in RAWHIDE
