Hopefully this workaround should work in all Ubuntu. '''Note:''' ''I have tested only for Intel Graphics Controller.'' ||<(-2 tablewidth="90%" style="border:none"> 1. Go to '''System''' ---> '''Preferences''' ---> '''Display''' || ||<( width="10%" style="border:none">||<( style="border:none">{{attachment:menu.png}} || ||<(-2 tablewidth="90%" style="border:none"> 2. You will see a screen similar to the following, where you can change refresh rate, resolution, rotation and detecting monitors. || ||<( width="20%" style="border:none">||<( style="border:none">{{attachment:display preferences.png}} || * In this screen as you see monitor will not get detected and you will not have options to change refresh rate, resolution and rotation. = Workaround = ||<(-2 tablewidth="90%" style="border:none"> 1. To know what is your controller open a terminal and execute the following command : || {{{ $ sudo lspci | grep -i vga }}} It should give message like this: {{{ $ sudo lspci | grep -i vga 00:02.0 VGA compatible controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (rev 0c) }}} ||<(-2 tablewidth="90%" style="border:none"> 2. Make sure that your hardware is not in the blacklist. Modify the script /usr/bin/compiz. Open a terminal and execute the following command : || {{{ $ sudo gedit /usr/bin/compiz }}} Search in the file the lines about the blacklist. There should be a pair of lines with your (i.e. intel) graphic card. Comment them out (meaning: put a '#' at the beginning of the line). It should look like this: {{{ # blacklist based on the pci ids # See http://wiki.compiz-fusion.org/Hardware/Blacklist for details #T=" 1002:5954 1002:5854 1002:5955" # ati rs480 #T="$T 1002:4153" # ATI Rv350 #T="$T 8086:2982 8086:2992 8086:29a2 8086:2a02 8086:2a12" # intel 965 #T="$T 8086:2a02 " # Intel GM965 #T="$T 8086:3577 8086:2562 " # Intel 830MG, 845G (LP: #259385) BLACKLIST_PCIIDS="$T" unset T }}} ||<(-2 tablewidth="90%" style="border:none"> 3. In xorg.conf, replace "vesa" with "intel". Open a terminal and execute the following command :|| '''Note:''' ''Make sure you take a backup of xorg.conf before editing.'' {{{ $ sudo gedit /etc/X11/xorg.conf }}} * Search for “vesa” and replace it with “intel”. * Save and close the file. ||<(-2 tablewidth="90%" style="border:none"> 4. Restart the computer and now you can change refresh rate, resolution, rotation and detecting monitors. ||
