I have been trying to fix my monitor resolution for a while now. However everything I have tried doesn't work or isn't permanent. I've changing resolution using xrandr. I've tried editing the X11 file. I've tried editing the lightdm configuration, but only get a black screen.
Currently I use a script every time I log in, but I would like my full resolution to be permanent. I would also like the other resolutions in between. Without running the script the maximum resolution I can get is 1024 x 768. I can get 1080 (not sure whether it is p or i). Please help me. Looking at a 4:3 boot screen, login screen and desktop on a 16:9 is very saddening :(.
If it helps I am using a Philips 234EL 1080p display coupled with Intel Sandy Bridge Graphics (2500 if I'm not mistaken)
Any help would be appreciated and thanks in advance.
