<\/a><\/p>\nThis software is not really intuitive. You’d need to click “left” or “right” and then click “apply” to see the effect. Keep doing this until you get the desired screen fit and then click “show” to show the parameters on the terminal. Copy the output.<\/p>\n
Then gedit or vi the following file \/etc\/X11\/xorg.conf, which I append below:
\npaste the line in between the “Monitor” Section as follows:<\/p>\n
Section “Monitor”
\n\tIdentifier\t“Generic Monitor”
\n\tOption\t\t“DPMS”
\n\tHorizSync\t30-83
\n\tVertRefresh\t55-76
\n\tModeline “NV1280x1024” 135.00 1280 1312 1456 1688 1024 1025 1028 1066 +hsync +vsync<\/p>\n
You’d need to the prefix of “Modeline” in front of the line. Notice that I added “NV” (or any thing to make it unique) in front of “1280×1024”. Well this is really the trick that took me over a couple hours to figure out. This string “NV1280x1024” needs to have a same counter part in the Display Section. In my case, it is as follows:<\/p>\n
\tSubSection “Display”
\n\t\tDepth\t\t24
\n\t\tModes\t\t“NV1280x1024”
\n#\t\tModes\t\t“1280×1024” “1024×768” “800×600” “640×480”
\n\tEndSubSection<\/p>\n
Notice that I comment out the original lines and all other Display sections so I can force X display
\nto use this particular mode I just specified. You may want to have more than one mode after you become more familiar with how the file works.<\/p>\n
Save the file then refresh the display by doing
\nCTRL-ALT-BACKSPACE <\/p>\n
The display should be what you intended. If not, keep editing the \/etc\/X11\/xorg.conf file until you get what you want.
\nThere it is. A bit tedious.<\/p>\n

Linux is notorious in positioning the horizontal position on your monitor. After installing the Ubuntu on my old Sony Vaio PCV-RX650, which has a Nvidia TNT2 display card, I found the display is shifted to the right, leaving a blank strip on the left and distorted image on the right. This was very annoying. I … Continue reading Setting\/Centering the Horizontal Display Position on Ubuntu or Linux<\/span>
