Also, I tried modifying /usr/lib/X11/xorg.conf.d/10-monitor.conf to fix this problem, but still does not work:

I'm using Gnome. System > Preference > Monitor screen resolution sticks to 800x600. What am I going to do?

EDIT:

xrandr -q

Screen 0: minimum 800 x 600, current 800 x 600, maximum 800 x 600
default connected 800x600+0+0 0mm x 0mm
   800x600         0.0*

Can you attach the output of xrandr -q? –  Samik Jun 8 '12 at 16:58
    
@Samik: see edits. –  Neigyl R. Noval Jun 8 '12 at 17:02
    
you can check what video driver is in use by typing lspci -v, that provides more verbose output. can you update the o/p of lspci with -v option? –  Samik Jun 8 '12 at 17:22
    
@Samik: I'm stuck here. What would be the video driver in this case? –  Neigyl R. Noval Jun 8 '12 at 18:17
    
no driver is currently in use, I think that's why the default vesa driver is kicking in and in your xorg.conf you have mentioned vesa as driver, one thing you can try, comment that line and open grub.cfg and in the menu entry add a line insmod i915 and then add i915.modeset=1 in the kernel line. then reboot. By this you will be loading Intel's i915 driver into kernel instead of vesa. –  Samik Jun 8 '12 at 18:29

enter image description here xrandr -q will gives the resolutions for your monitor and you can choose one by using xrandr -s 1366x768 you can choose the resolution you want .

In my situation, does that mean I am eternally stuck at 800*600? –  Neigyl R. Noval Jun 8 '12 at 17:07
    
your issue seems different you got proper VGA drivers installed ? –  AgentCool Jun 8 '12 at 17:11
    
@NeigylR.Noval you can add new resolution with xrandr --newmode modename modeline then xrandr --addmode modename where you can get the modeline by gtf width height refreshrate –  Samik Jun 8 '12 at 17:12
    
@Raja: I don't know what drivers to install on the first place. I have edited my question with lspci -v output. –  Neigyl R. Noval Jun 8 '12 at 18:18
