Solve the problem that the display resolution of ThinkPad x200 in Ubuntu cannot reach 1280*800

From: http://www.php-oa.com/2008/12/11/ubuntu-thinkpad-x200-1280-800.html

 

In ubuntu8.10, the default Xorg. conf setting does not work well. The default setting is 1074X768, but the x200 standard is 1280x800, which cannot be well set in the system.System> preferences> screen resolutionCannot be set properly.

I have updated the settings many times, and this is the last time. First, make sure that your system has an Intel driver installed.

$ sudo apt-get install xserver-xorg-video-intel

Then, use gedit to set Xorg. conf.

$ sudo gedit /etc/X11/xorg.conf

Then add the following parts

Section "Monitor"
    Identifier    "Configured Monitor"
EndSection

Section "Monitor"
    Identifier    "HDMI-1"
    Option        "Ignore" "True"
EndSection

Section "Monitor"
    Identifier    "HDMI-2"
    Option        "Ignore" "True"
EndSection

Section "Screen"
    Identifier    "Default Screen"
    Monitor        "Configured Monitor"
    Device        "Configured Video Device"
    DefaultDepth     24
    SubSection "Display"
        Modes "1280x800" "1024x768"
# The following line was an auto-configuration added by an external VGA projector; you might leave it out to try
# letting the system detect dimensions appropriate for whatever display you happen to use.
        Virtual    2432 864
    EndSubSection
EndSection

 Section "Device"
     Identifier    "Configured Video Device"
     Driver        "intel"
     Option        "monitor-HDMI-1" "HDMI-1"
     Option        "monitor-HDMI-2" "HDMI-2"
 EndSection

 

Then save and close gedit. Basically, you can. It seems that it's not because of the driver, but because of the HDMI. Then you just need to restart your xwindows.

System> preferences> screen resolutionSelect again.
