  • Try it once.. In dash search System Settings and open it. Click on the Displays icon and try to change Resolution. Hope it would help.. Reply what happens.. – Saurav Kumar Sep 08 '13 at 12:20
  • @SauravKumar thz for your reply. I tried it. But there are also other problems. When I pointed dash home with my mouse, there is no effect. I meant is when i point dash home, the effected icon is Home folder.EFFECTED ICON AND REAL POINTING ARE MISS MATCHED !!! Finally i can open System settings but system setting is opened in the middle of the screen where I cannot reach (because there is no scroll). You can see in my picture, I opened Mysql query browser, but can't access because query browser is opened in the middle of the screen where i can't access. pls help me. – yu mon Sep 09 '13 at 06:50
  • ok.. open terminal(ctrl+alt+t) run this command.. xrandr --output VGA1 --mode 1366x768 Although you are not able to see terminal just type this be sure you are not doing any mistake.. Here 1366x768 is resolution you want to set. I recommend you to set the same resolution you are currently using for Windows – Saurav Kumar Sep 09 '13 at 07:00
  • My windows 7's recommeded screen resolution is 1280x800 and it is the highest. Can I change? – yu mon Sep 09 '13 at 07:14
  • Then use xrandr --output VGA1 --mode 1280x800 first.. If it fails then try xrandr --output VGA1 --mode 1366x768 it it also fails then try some other low resolution like xrandr --output VGA1 --mode 1024x768 – Saurav Kumar Sep 09 '13 at 07:17
  • I run root@ubuntuntwo~# xrandr --output VGA1 --mode 1280x800. And the err is " xrandr: Failed to get size of gamma for output default. warning: output VGA1 not found; ignoring" – yu mon Sep 09 '13 at 07:35
  • If you are not able to see what the display shows then it is fairly impossible to fix your problem.. Uff!! Okay! Follow my answer.. – Saurav Kumar Sep 09 '13 at 08:10

Be sure the you are following these steps very precisely without clicking or highlighting other window.. So I recommend you don't click some other place while following these steps..

  • Open System Settings from Dash (as you told that you already opened but it was not visible, so don't worry, without seeing it you can change..)

  • Without cling some other place type displays and press Enter

  • again without clicking any other press Alt+R

  • then press Down arrow key once

  • then press Alt+A two times then press Enter again two times..

Try it it will change your resolution!! Reply for further assistance!!

  • I 've tried Saurav. I've tried many times. After restarting, the display is same as before. No change. :( – yu mon Sep 09 '13 at 08:45
  • Okay! Last option.. repeat above step and press alt+a key once. If still not working.. Then try to these option: VGA , LVDS ,DP1 , TV , TMDS-1 , TMDS-2 , LVDS1 , DVI1 ,VGA-0 , S-video , DVI-0 in place of VGA1 in this command: xrandr --output VGA1 --mode 1366x768. If still doesn't work then I would recommend you to use Windows + Ubuntu Dual Boot – Saurav Kumar Sep 09 '13 at 08:53
  • Thz for ur patient help. I have done all the best. but doesn't change. Now I found that this is because new pae download "linux-image-3.2.0-52-generic-pae". My old pae version is 3.2.0-29-generic-pae. So I tried while first starting, I click shift and enter into bootloader menu. I chose "previous version" tap. and I choose my old 3.2.0-29. Finally, I can restore my previous state. Why do this become fine? I don't know reason. And friend, how to change 3.2.0-29 to be my default pae? – yu mon Sep 09 '13 at 09:19
