I am looking for a way to increase the display resolution of my ubuntu desktop to a minimum of 4096x4096. I searched on the web but couldn't find a solution to this. Is there a way to make native resoltuion higher? I would be glad if you can share it with me or direct me in the right way to achieve this myself. Thanks.
You can use xrandr, though I recommend that you do not set your resolution to something higher than what your monitor can handle.
xrandr with no arguments returns information about your current displays:
mgodby@mg-ws1:~$ xrandr
Screen 0: minimum 320 x 200, current 3200 x 1200, maximum 16384 x 16384
DisplayPort-0 connected primary 1600x1200+0+0 (normal left inverted right x axis y axis) 408mm x 306mm
1600x1200 60.0*+
1400x1050 74.9 59.9
1280x1024 75.0 60.0
1280x960 60.0
1152x864 75.0
1024x768 75.1 70.1 60.0
832x624 74.6
800x600 72.2 75.0 60.3 56.2
640x480 75.0 72.8 66.7 60.0
720x400 70.1
DVI-0 connected 1600x1200+1600+0 (normal left inverted right x axis y axis) 408mm x 306mm
1600x1200 60.0*+
1400x1050 74.9 59.9
1280x1024 75.0 60.0
1280x960 60.0
1152x864 75.0
1024x768 75.1 70.1 60.0
832x624 74.6
800x600 72.2 75.0 60.3 56.2
640x480 75.0 72.8 66.7 60.0
720x400 70.1
mgodby@mg-ws1:~$
You can set your resolution like so (replace DVI-0 with your display name and 1400x1050 with your desired resolution):
xrandr -d DVI-0 -fb 1400x1050
A simple man xrandr will give you more information, and online searching will get you even more information yet.
