    Can't get my video card working right


    I just installed Ubuntu on my Toshiba Portege 3500. I can't get it to display at more than 800x600, which sucks because in Windows on the same machine I can get 1024x768. I found a webpage that said my CyberBlade video card works with xorg's trident driver, so I edited my xorg.conf file to use that one. Nothing changed. Am I missing some step required to update xorg? Oh, and I did restart the computer since I changed it, so it's not that.

    Can you post the bottom portion of your xorg.conf? Start at "Section "Device"" to the end of the file please.

    There are several lines that say Section "Device", so here is the entire file except for a large comment block at the beginning:

    Code:
    Section "InputDevice"
    	Identifier	"Generic Keyboard"
    	Driver		"kbd"
    	Option		"XkbRules"	"xorg"
    	Option		"XkbModel"	"pc105"
    	Option		"XkbLayout"	"us"
    EndSection
    
    Section "InputDevice"
    	Identifier	"Configured Mouse"
    	Driver		"mouse"
    EndSection
    
    Section "InputDevice"
    	Identifier	"Synaptics Touchpad"
    	Driver		"synaptics"
    	Option		"SendCoreEvents"	"true"
    	Option		"Device"		"/dev/psaux"
    	Option		"Protocol"		"auto-dev"
    	Option		"HorizEdgeScroll"	"0"
    EndSection
    
    Section "Device"
    	Identifier	"Configured Video Device"
    	Driver 	"trident"
    EndSection
    
    Section "Monitor"
    	Identifier	"Configured Monitor"
    	Driver 	"trident"
    EndSection
    
    Section "Screen"
    	Identifier	"Default Screen"
    	Monitor		"Configured Monitor"
    	Device		"Configured Video Device"
    EndSection
    
    Section "ServerLayout"
    	Identifier	"Default Layout"
    	Screen		"Default Screen"
    	InputDevice	"Synaptics Touchpad"
    EndSection

    Execute this
    Code:
    sudo dpkg-reconfigure xserver-xorg
    Reconfigure display settings. Select supported Resolutions ( modes ), trident Video Driver and Depth 16.
    Press Alt+Ctrl+Backspace to restart X Server or Reboot machine.
    In case it doesn't work, execute this
    Code:
    sudo lspci | grep VGA
    Post output here.

    dpkg-reconfigure just asked me various questions about my keyboard (which was and still is working properly) and nothing to do with my video card or display. No surprise, therefore, that it didn't fix the problem, even after I restarted.

    The other gave this output:
    Code:
    01:00.0 VGA compatible controller: Trident Microsystems CyberBlade XPAi1 (rev 82)

    Thats strange. That command configure everything including KeyBoard, Mouse, Monitor and Video Card.
    Which version of Ubuntu are you using?
    Post the output of this
    Code:
    cat /etc/lsb-release
    Could you post all the contents of xorg.conf file or attach it here ?

    Code:
    DISTRIB_ID=Ubuntu
    DISTRIB_RELEASE=8.04
    DISTRIB_CODENAME=hardy
    DISTRIB_DESCRIPTION="Ubuntu hardy (development branch)"
    I already posted almost all of my xorg.conf file, here is the whole thing:
    Code:
    # xorg.conf (X.Org X Window System server configuration file)
    #
    # This file was generated by dexconf, the Debian X Configuration tool, using
    # values from the debconf database.
    #
    # Edit this file with caution, and see the xorg.conf manual page.
    # (Type "man xorg.conf" at the shell prompt.)
    #
    # This file is automatically updated on xserver-xorg package upgrades *only*
    # if it has not been modified since the last upgrade of the xserver-xorg
    # package.
    #
    # If you have edited this file but would like it to be automatically updated
    # again, run the following command:
    #   sudo dpkg-reconfigure -phigh xserver-xorg

    You are using Testing Branch of Ubuntu and this release tries to reconfigure Display settings itself. There are a few problem that are yet to be fixed.
    Edit three Sections in xorg.conf.
    Code:
    sudo nano /etc/X11/xorg.conf
    These sections:
    Code:
    Section "Device"
        Identifier    "Configured Video Device"
        Driver        "trident"
        BusID        "PCI:1:0:0"
    EndSection
    
    Section "Monitor"
        Identifier    "Configured Monitor"
        Option        "DPMS"
        HorizSync      30-71
        VertRefresh    50-100
    EndSection
    
    Section "Screen"
        Identifier    "Default Screen"
        Monitor       "Configured Monitor"
        Device        "Configured Video Device"
        DefaultDepth    16
        SubSection "Display"
            Depth        16
            Modes        "1280x1024" "1024x768"
        EndSubSection
        SubSection "Display"
            Depth        24
            Modes        "1280x1024" "1024x768" 
        EndSubSection
    EndSection

    So that's what "Development Branch" means! I just chose the most recent release available, on the theory that it was probably the best.

    I made your changes to the xorg file and restarted the computer. First I got a black screen with a mouse shaped like an X and a message saying that it had gone into "Low graphics mode" or something. Than, that disappeared and I got a command line. Then, before I could do anything there, that disappeared also and I got the normal login screen. It doesn't look like a low graphics mode to me; but I still can't make the screen bigger than 800x600.

    It makes me consider starting over again and installing a non-beta operating system.

    Its a Developement branch and should not be installed in Production machine or for regular use. I would suggest you try Ubuntu 7.10 ( Gutsy ).
    Try this
    Open xorg.conf file again and set Driver "vesa" instead of "trident". vesa is a generic driver and works fine with most of Graphics Cards.
