    Question Rotating display in Ubuntu

    I'm currently using Ubuntu 8.04 and would like to rotate my screen vertically as my Samsung SyncMaster 204B is able to do physically. In Windows there was a simple program called MagicRotation that with one click I could go from my usual 1600x1200 to a 1200x1600 with everything appropriately oriented.

    This is a rather key thing for me since I got quite used to reading documents and browsing the web that way. Unfortunately I haven't found any way to do this in Linux. The only solutions I saw were only for NVIDIA video cards and I have a Radeon 9800 Pro.

    So, how would I go about rotating my screen back and forth? What additional information is needed about my computer before this can be answered?

    Thanks for your help.

    Re: Rotating display in Ubuntu

    Have you tried rotating it through:

    System > Preferences > Screen Resolution

    ATI drivers, ergo...

    The X Server does not support the XRandR extension. Runtime resolution changes to the display size are not available.
    And when I do a sudo displayconfig-gtk there are no options regarding rotation that I can see.

    Is there another forum I should post this in to get an answer?

    The fgrlx driver doesn't support xrandr.

    If you un-install it and go back to the open radeon driver you will be able to use xrandr to rotate your screen.

    I've gone back to the open ati drivers now and indeed the rotation options appeared. After fixing the virtual desktop size in xorg.conf I was able to successfully rotate the screen. Before throwing a minor party though I found the screen to be refreshing horrifyingly slowly. It was completely unusable.

    Running glxgears while vertical produced a completely normal fps.

    Thank you for your advice, any thoughts on this development?

    Here's my xorg.conf:
    Code:
    Section "ServerLayout"
    	Identifier     "Default Layout"
    	Screen      0  "aticonfig-Screen[0]-0" 0 0
            Option          "AIGLX"         "true"
    EndSection
    
    Section "Files"
    EndSection
    
    Section "Module"
    EndSection
    
    Section "InputDevice"
    	Identifier  "Generic Keyboard"
    	Driver      "kbd"
    	Option	    "XkbRules" "xorg"

    EndSection
    
    Section "InputDevice"

    	Option	    "ModelName" "Generic Autodetecting Monitor"
    	Option	    "DPMS" "true"
            HorizSync       30-81
            VertRefresh     56-75
    EndSection
    
    Section "Device"
    	Identifier  "aticonfig-Device[0]-0"
    	Driver      "ati"
    	BusID       "PCI:1:0:0"
            Option		"XAANoOffscreenPixmaps"
    
    EndSection
    
    Section "Screen"
    	Identifier "aticonfig-Screen[0]-0"
    	Device     "aticonfig-Device[0]-0"

    	SubSection "Display"
    		Viewport   0 0
    		Depth     24
               	# ADD A VIRTUAL LINE TO PROVIDE FOR THE LARGEST SCREENS YOU WILL HOTPLUG 
               	Virtual    1600 1600 
    	EndSubSection
    EndSection
    
    Section "DRI"
            Mode 0666
    EndSection
            
    Section "Extensions"
            Option "Composite" "Enable"
    EndSection

    Re: Rotating display in Ubuntu

    Have you tried adding "Option" "XRandR" "True" to your xorg.conf under the device section? I know that enables it for nvidia cards, I think it's an X option, not and nvidia option.

    Back up your xorg.conf first, save all your work and be prepared for a hard reboot if it fails.
