How to get back previous resolution (1440-900) using displayconfig-gtk

Asked by Kiran

While exploring Ubuntu, I have changed LCD settings using displayconfig-gtk. Now Ubuntu is running in low graphics mode. How can I get back my previous resolution (I don’t remember previous settings)

I am using Dell Inspiron 640m notepad. The screen resolution is 1440-900 (widescreen). LCD model number: WF320. Graphics card: Intel 945.

I have tried different setting options using displayconfig-gtk. But it did not help me in getting positive result

Please let me know how can I get 1440-900 resolution back. Also the settings i have make in displayconfig-gtk.

I would suggest you let X build your config file from the command line. Go to a terminal and type the following:

sudo dpkg-reconfigure -phigh xserver-xorg

Your old "/etc/X11/xorg.conf" file will be backed up in the process. Then close everything you are working with and press Alt+Ctrl+Backspace (this kills the X server, which means it kills the graphics session) and then you'll be back in the login window, most likely with a better resolution.

If not, try other drivers (the Intel experimental 9xx driver for instance) and check your luck. 1024x768 is always a good bet for resolution, from there you can move up and down.

Good luck!

After using displayconfig-gtk you must select the available display resolution using the System->Preferences->Screen Resolution...

Using displayconfig-gtk you can also load the specific windows .inf file of your monitor usually you can find it on the windows monitor drivers installation disk coming with your pc or searching using the web.

hope this helps
