Fixing Ubuntu Issues: Flickering Pointer

Upon instlaling Ubuntu 11.10 some of may notice that the cursor constantly flickers and sometimes disappears randomly. To solve this do the following:

Note: xorg.conf is depreciated in Ubuntu 11+

Type the following in a new console window:

cd /usr/share/X11/xorg.conf.d

sudo touch 10-monitor.conf

sudo gedit 10-monitor.conf

Paste the following into the file, changing variables where indicated by the comments

Section "Monitor"
    Identifier    "Monitor0"
EndSection

Section "Device"
    Identifier    "Device0"
    Driver        "nvidia" #Choose the driver used for this monitor
EndSection

Section "Screen"
    Identifier    "Screen0"  #Collapse Monitor and Device section to Screen section
    Device        "Device0"
    Monitor       "Monitor0"
    DefaultDepth  24 #Choose the depth (16||24)
    SubSection "Display"
        Depth     24
        Modes     "1680x1050" #Choose the resolution
    EndSubSection
EndSection

Save the file.

Press CTRL + ALT + FI to enter terminal mode and type the following:

sudo stop lightdm

sudo start lightdm

Log in and notice that the cursor does not flicker any more. You may have to unplug your mouse and plug in back in to get the cursor to work. If you do not get back to the graphical mode after starting the display manager, press CTRL + ALT + F7
