Thread: screen resolution on ubuntu

  1. screen resolution on ubuntu

    Hi, I just brought up my new computer on ubuntu 7.

    System -> Preferences -> Screen Resolution only goes up 1024x768. My
    monitor is 1600x1200, and Windoze was able to drive that just fine.
    My graphics card is an NVidia GeForce 6150 SE.

    In my /etc/X11/xorg.conf it said

    Section "Screen"
    Identifier "Default Screen"
    Device "Generic Video Card"
    Monitor "Generic Monitor"
    DefaultDepth 24
    SubSection "Display"
    Depth 1
    Modes "1024x768" "800x600" "640x480"
    EndSubSection
    ...
    SubSection "Display"
    Depth 24
    Modes "1024x768" "800x600" "640x480"
    EndSubSection
    EndSection

    I changed '"1024x768"' to '"1600x1200" "1024x768"' on each "Modes"
    line and rebooted. The system still wouldn't let me choose the higher
    resolution.
    Then I changed the "Device" line to "NVIDIA GeForce 6150 SE Video
    Card" and tried to reboot, and the system couldn't bring up the
    graphics, I had to reboot in safe mode and restore the xorg.conf file.
    I'm really wondering if "Generic Video Card" and "Generic Monitor" are
    limiting me, and what I should change them to.

    I just solved this on my own. First I had to download the nvidia-glx-
    new package, rebooted, which didn't work. I looked at the X logfile,
    and it looked like the device was found at PCI:0:13:0 but the
    xorg.conf file was looking for it at PCI:0:5:0, so I edited the
    xorg.conf file and rebooted again. I had to manually edit the
    xorg.conf to include the 1600x1200 resolution again, rebooted, and
    viola! 1600x1200 resolution!
