    cannot get resolution to be 1024x768 on Toshiba Satellite Laptop

    I have recently installed Ubuntu on my Toshiba Satellite A25-S207 Laptop. Everything runs great except that the resolution will not go above 800x600.

    I had this problem before on the same laptop and was able to fix it but cannot find the fix now (I had to wipe my laptop clean in order to remove some pesky Windows partitions and reinstall Ubuntu)

    I have found several "fixes" but none work. I tried the one below as well as it applies almost perfectly to my problem

    "I just installed the latest ubuntu 10.04 on a Toshiba-Tecra having "Trident Microsystems Cyberblade XP4m32" Monitor. After install resolution is defaulted to 800x600. I followed a method advised in some threads (arount xrandr and cvt) to increase the size (my laptop works with 1024x768 under XP). This was done OK and I obtained the resolution 1024X768 appearing in the drop list resolution options of the Monitor preferences but when I select the option if fails. Alternatively, when I execute
    $ xrandr --output default --mode 1024x768_60.00
    i got the message "xrandr : screen cannot be larger than 800x600 (desired size 1024X768)

    I also saw a possible fix proposing to add "HorizSync 31.50-48.00" in Xorg.conf but I then I DO NOT have such a file in my /etc/x11/ after ubuntu install (supposing that this will fix my problem !!!)

    Thanks to help me to progress
    Boot into recovery mode, when you get to the command line type:
    sudo Xorg -configurewhich will create a default /etc/X11/xorg.conf file. Add the lines:
    HorizSync 31.0 - 70.0
    VertRefresh 40.0 - 75.0to the Monitor section then reboot."


    However when I entered the "sudo Xorg -configure" line my computer spit back saying that "sudo" is not an acceptable command

    How can I fix this? It's very annoying.

    Thanks

    i would re-install, simply because you can't use sudo.

    if you can't sudo, that will really limit you...



    there is a alternative to sudo: su root
    if you really dont want to re-install, try running these:
    Code:
    su root
    Xorg -configure

    Hi

    I think that in recovery mode, you dont need sudo as you are root already?

    The right solution is to create an xorg.conf file. I have had to do this to get a Trident Cyberblade (not your model) to run a resolution higher than 800x600.

    You can create the xorg.conf file in a normal session by using
    gksu gedit /etc/X11/xorg.conf
    This will create an empty file for you to edit.

    I tried doing the "gksu gedit/etc.X11/xorg.conf" in the terminal and it would open a tab that said "starting administr..." but then it closes and nothings seems to have happened.

    Should I be doing this at the command line?

    the problem seems to be that I don't have a "xorg.conf" file in the etc/x11 folder and can't seem to get one there

    Backup your existing xorg.conf file and try that suggested one:

    Code:
    sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf-backup
    Code:
    gksudo gedit /etc/X11/xorg.conf
    Delete everything in the monitor section and paste in:

    Section "Monitor"
    Identifier "Configured Monitor"
    Option "DPMS" "true"
    HorizSync 30.0-60.0
    VertRefresh 50.0-70.0
    EndSection

    Section "Screen"
    Identifier "Default Screen"
    Monitor "Configured Monitor"
    Device "Configured Video Device"
    DefaultDepth 24
    SubSection "Display"
    Depth 24
    Modes "1024x768" "800x600"
    EndSubSection

    EndSection



    Save and close and log out/in to restart X server....


    BTW.mind that is X11 and not x11 !!

    If it should not be enough to have the monitor section,try :

    Section "Monitor"
    Identifier "Configured Monitor"
    Option "DPMS" "true"
    HorizSync 30.0-60.0
    VertRefresh 50.0-70.0
    EndSection

    Section "Screen"
    Identifier "Default Screen"
    Monitor "Configured Monitor"
    Device "Configured Video Device"
    DefaultDepth 24
    SubSection "Display"
    Depth 24
    Modes "1024x768" "800x600"
    EndSubSection
    EndSection

    Section "InputDevice"
    Identifier "Generic Keyboard"
    Driver "kbd"
    Option "CoreKeyboard"
    Option "XkbRules" "xorg"
    Option "XkbModel" "pc105"
    Option "XkbLayout" "es"
    EndSection

    Section "InputDevice"
    Identifier "Configured Mouse"
    Driver "mouse"
    Option "CorePointer"
    Option "Device" "/dev/input/mice"
    Option "Protocol" "ExplorerPS/2"
    Option "ZAxisMapping" "4 5"
    Option "Emulate3Buttons" "true"
    EndSection

    Section "InputDevice"
    Identifier "Synaptics Touchpad"
    Driver "synaptics"
    Option "SendCoreEvents" "true"
    Option "Device" "/dev/psaux"
    Option "Protocol" "auto-dev"
    Option "HorizScrollDelta" "0"
    EndSection

    Section "Device"
    Identifier "Trident Microsystems CyberBlade XPAi1"
    Driver "trident"

    EndSection

    THANKS REALZIPPY that last bit worked like a charm. after I rebooted I just went into "Monitor" and changed it to "1024x768" and PERFECT.

    Thanks to everyone that helped me on this. You're all great!
