xfree86 issues

[Chris Locke]

I'm having problems with XF86. It will not let me run a resolution
higher than 1024x768. I have a 19inch monitor so it is rather ugly. I
have tried using different combination of drivers for both monitor or
video card and nothing works. This system dual boots between redhat 9
and fedora and under redhat 9 I can run 1600x1200 no problem. I tried
editing the XF86Config file by hand to give it the same settings as my
redhat install but it still goes back to 1024x768. Anyone else have this
problem or know of a resolution for it?

thanks

This is devoid of almost any useful information.. which graphics card
are you using?  What are the contents of your XFree86 log
(/var/log/XFree86.0.log)?  What are the contents of your XF86Config
file?

Its also usually a good idea to check the bug database, if this has
already been reported a temporary workaround may be in there.  Or you
could provide additional information to make the debugging process go
faster.  ^,^

The usual reason for this is the values on these lines in the Monitor section 
of your /etc/X11/XF86Config:

        HorizSync    31.5 - 150.0
        VertRefresh  60.0 - 60.0

This is from my one which is driving an LCD panel, so I restricted the 
vertical refresh to 60Hz.  The values in the HorizSync entry are in kHz and 
basically describe how fast your monitor can draw.  The higher resolutions 
and refresh rates need faster drawing, if your Monitor description is telling 
X that it can't cope with that it won't let you select them.

Another important bit is this:

Section "Screen"
        Identifier "Screen0"
        Device     "Videocard0"
        Monitor    "Monitor0"
        DefaultDepth     24
        SubSection "Display"
                Depth     24
                Modes    "1024x768" "800x600" "640x480"
        EndSubSection
EndSection

You need to make sure your desired modes are listed there (yours might be 
quite different, but the same basic layout).  X has a ton of built-in common 
modes in the axb format that you can try, like "1280x1024" or
"1600x1200" 
assuming your monitor can cope.

If this doesn't help much, why not post your /etc/X11/XF86Config?

This happens usually because the config for the monitor is not set
correctly.

try redhat-configure-xfree86 - and choose more appropirate monitor
setting.  (for example 'hardware -> Monitor Type -> Generic CRT
Display -> Monitor 1280x1024). Now you can change the resolution as
well.

When you hand edited the XF86Config file, did you forget to migrate the
HorizSync and VertRefresh values found in the Monitor Section?

I ended up running diff against the two files and did find a VertRefresh
I missed....all is good now. I just wonder why in 9 it could set it up
properly for me but in fedora it doesn't. Oh well it's all good now.
