Resolution problem!

De-code · 08-01-2008, 01:58 AM

I know that you get this question a lot on the forum. I am running Ubuntu 8.04 with KDE. I can't change my screen res. at all when I go through the display setup, when I pick my resolution it won't let me apply it.
When I change it to 1024 x 768 from the desktop I get a SIGABRT error message, and it reverts back to 800 x 600.

I tried to go through the xorg config file but it wont let me change anything. It says I don't have the permission.

I have tried the XFCE environment and it works fine in 1024 x 768.

Thank you in advance for the help.

using ubuntu 7.10, I click on System/Administration/Screens and Graphics
and a password request pops up. from there I can change my screen resolution.
8.04 should not be much different...

I tried to do it that way but it will not let me apply the changes.

a little more searching and I found this...

For you to have permission to alter a system file, you have to open it as root.

Run

Code:

gksu gedit /etc/X11/xorg.conf

in order to be able to save.

just copy that line of code and past it into a terminal, make your changes and you should be able to save it...

This is what I have in my xorg file:

Section "Device"
Identifier "Configured Video Device"
EndSection

Section "Monitor"
Identifier "Configured Monitor"
EndSection

Section "Screen"
Identifier "Default Screen"
Monitor "Configured Monitor"
Device "Configured Video Device"
EndSection

Should it look like that if not what do I add.

hope that is not your complete xorg file...

here is mine...

Code:

# /etc/X11/xorg.conf (xorg X Window System server configuration file)
#
# This file was generated by dexconf, the Debian X Configuration tool, using
# values from the debconf database.
#
# Edit this file with caution, and see the xorg.conf(5) manual page.
# (Type "man xorg.conf" at the shell prompt.)
#
# This file is automatically updated on xserver-xorg package upgrades *only*
# if it has not been modified since the last upgrade of the xserver-xorg
# package.

# If you have edited this file but would like it to be automatically updated

#   sudo dpkg-reconfigure -phigh xserver-xorg

That was just a part of the xorg file pertaining to the display settings.

Is there a program I can run that will recognize what hardware I have?
I think that is where the problem is.

Things are definitely different in the xorg.conf for 8.04, there is definitely a driver issue here. KDE starts up like a charm, I hadn't used it, yet -- nice. I found out I could rotate my monitor if I want (cool).

What is your video card?

At the terminal, type:

Code:

sudo lshw

You should have a bunch of lines that looks like this:

Code:

        *-display UNCLAIMED
             description: VGA compatible controller
             product: 82945G/GZ Integrated Graphics Controller
             vendor: Intel Corporation
             physical id: 2
             bus info: pci@0000:00:02.0
             version: 02
             width: 32 bits
             clock: 33MHz
             capabilities: msi pm vga_controller bus_master cap_list
             configuration: latency=0

This is a fishing trip, still checking things out here.

Hey Jer, when I typed that I got this:

*-display UNCLAIMED

product: 82865G Integrated Graphics Controller
vendor: Intel Corporation
physical id: 2
bus info: pci@0000:00:02.0

I could bring up the program that lets me rotate as well as change my res. but after I change my res I get the sigabrt error message in KWIN.

jerril · 08-03-2008, 02:56 PM

De-code;

I got a suggestion to try this from Ubuntu forums, I have no idea what it is, but person looking for a solution said it worked for that card:

Code:

XORG_SYNC_RANGES=yes sudo dpkg-reconfigure -phigh xserver-xorg

Here is the page I got this suggestion from.
