OK guys i figured it out!! after three days and destroying my system twice, i finally changed the resolution of my monitor to 1024x768. i have an HP monitor and just so happens HP doesnt support linux, so i havent been able to find a software driver for it to run in ubuntu. that means that ubuntu can't detect what the settings of the monitor are, so it reverts to 'low graphics mode". which means that you cant set the resolution higher that 800x600.(to put it nicely that SUCK!!!) after hours looking through google results i found the answer.
the problem is, the code provided in this how-to will set the resolution to 1024x768_70.00mhz, and my monitor runs at 60.00mhz. so the link above will show you how to do it but you may have to change part of it to get it to work for you.
this is what i did:
first open the configuration file with:
then look for the lineCode:gksudo gedit /etc/gdm/Init/Default
it should be near the top. position the curser just below these lines and past the code:Code:PATH=/usr/bin:$PATH OLD_IFS=$IFS
(the 60.00 part outside the "" is the part i had to change to make mine work)Code:xrandr --newmode "1024x768_60.00" 60.00 1024 1072 1176 1328 768 771 775 798 -hsync +vsync xrandr --addmode VGA1 1024x768_60.00
make sure that the code is two different lines and that they are all the way on the left margin.save and close the file. now restart your computer. login and go to system>preferences>display. now 1024x768 should be one of the options you can chose.
i know alot of people have this problem so i hope that this helps. good luck
