Force higher screen resolutions

Asked by David Samuels

I'm running Ubuntu 7.10 on an HP Compaq nc6320 which has a native resolution of 1400 x 1050 and I cant get a resolution of better than 1280 X 1024.

I tried running the command:

sudo dpkg-reconfigure -phigh xserver-xorg

but only got the following message:

xserver-xorg postinst warning: overwriting possibly-customised configuration file; backup in /etc/X11/xorg.conf.20080114114528

Can anyone help?

Try to edit /etc/X11/xorg.conf manually.
Find in your xorg.conf part:

SubSection "Display"
  Depth 24
  Modes "1280x1024"
 EndSubSection

(maybe it will not look right so)

and add new resolutin.

Example:
SubSection "Display"
  Depth 24
  Modes "1400x1050" "1280x1024"
 EndSubSection

When I looked at /etc/X11/xorg.conf, I found it already showed the reslution. Here's what it says:

Section "Screen"
 Identifier "Default Screen"
 Device "Intel Corporation Mobile 945GM/GMS, 943/940GML Express Integrated Graphics Controller"
 Monitor "Generic Monitor"
 DefaultDepth 24
 SubSection "Display"
  Modes "1400x1050"
 EndSubSection
EndSection

Despite this, when I go to System>Preferences>Screen Resolution, the highest it offers is 1280 x 1024

Install package "915resolution" (if you don't have it).
Change resolution using command "915resolution 5c 1400 1050"

For automatically set this resolution at start add to file /etc/rc.local line:
915resolution 5c 1400 1050

(it must be before line "exit 0")

Here is my current xorg.conf -- hope it helps. Remember to restart after modding and remember to save the old one first under another name (e.g. xorg-yyyymmdd.conf.old:

David!
Thanks, but not help for me.
My resolution is still 1024x768.
I using Ubuntu 8.02.2LTS with Gnome.
Some other things?
ps: how can I change resolution from keyboard shortcut? ( in the older linux operation systems with CTRL-ALT-minus to increment resolution, CTRL-ALT-plus decrement resolution, but on the notebook??? )
thanks and bye: fgy

I have a HP Compaq nc6320 notebook with 15" XGA display, you have too nc6320, but
your notebook have an SXGA display, to my mind.
Am I right, or not?

<Am I right, or not?>

I don't know. My display is 1400 x 1050 (as I said in massage 1) and is OK.
