Re: [fedora-virt] F12 virtual screen resolution

The only options in the guest are 640x480 and 800x600.
I don't know where the list is stored where I could add another set of 
values.

I do this with the following /etc/X11/xorg.conf file.  You'll want to
adjust the resolutions in the "Modes" line for your screen.

Section "ServerLayout"
    Identifier     "Default Layout"
    Screen      0  "Screen0" 0 0
    InputDevice    "Keyboard0" "CoreKeyboard"
EndSection

Section "InputDevice"
    Identifier  "Keyboard0"
    Driver      "kbd"
    Option	    "XkbModel" "pc105"
    Option	    "XkbLayout" "us"
EndSection

Section "Device"
    Identifier  "Videocard0"
    Driver      "cirrus"
EndSection

Section "Monitor"
    Identifier  "Monitor0"
    HorizSync   31.5-62.5
    VertRefresh 50-70
EndSection

Section "Screen"
    Identifier "Screen0"
    Device     "Videocard0"
    Monitor    "Monitor0"
    DefaultDepth     24
    SubSection "Display"
    	Viewport   0 0
    	Depth     24
    	Modes     "1280x800" "1024x768"
    EndSubSection
EndSection

Thanks for response. I edited the  /etc/X11/xorg.conf in the client and 
added a modes line containing 1280x800, 1024x768 and 800x600 but the gui 
display change still only offers 800x600 and 600x480. Rebooting made no 
difference.  Brendan

Hmm.  Works like a charm for me with Centos 5.3 and 5.4 guests.  Maybe
a clue can be found in /var/log/Xorg.0.log on the guest.  What reason
does it give for discarding, say, 1024x768?

Jerry, The /var/log/Xorg.0.log shows that the Xorg program attempts to 
use a whole range of resolutions and rejects most of them as either "Bad 
mode clock/interface/doublescan" or "hsync out of range" the latter 
applied, for example, to "1024x768". Our target systems are Centos 5.3 
but I chose F12 as the base because I hoped that it would give me the 
best features, particularly a higher screen resolution for the guests.

F12 virtual screen resolution

[Brendan Whelan]

Thanks to all those who responded with suggestions. The solution was.....
I edited /etc/X11/xorg.conf on the client and:

Added>>>>>>>>> this section
Section "Monitor"
    Identifier  "Monitor0"
    HorizSync   31.5-62.5
    VertRefresh 50-70
EndSection

In the "Screen" secion:
Added	Monitor    "Monitor0"

In the display subsection:
Added/revised		Modes     "1280x800" "1024x768" "800x600"

After a reboot of the client, the screen resolution was 1280x800, which is fine and the GUI pull-down list of resolutions included a range of options.
