Video flicker on Inspiron 6000 with kununtu 8.10


First Linux install. Everything seems to work except for a screen flicker every few seconds. X.org log lists the following:
Information intel(0): EDID vendor "SEC", prod id 12888
Information intel(0): Printing DDC gathered Modelines:
Information intel(0): Modeline "1280x800"x0.0 71.11 1280 1328 1360 1440 800 802 808 823 -hsync -vsync (49.4 kHz)
Information intel(0): EDID vendor "SEC", prod id 12888

Tried changing to "1024 x 768"
Tried changing refresh to "auto" from 60 hz
No change.

Looked in Tutorials and forums and did not see anything. Where would I go to find info on errors like this?

Where do I find the info on hardware like in "System" in windoze? All docs lost with HD crash.

#sudo lshw
#sudo lspci -v


The problem is due to the less stable Xorg in *buntu.

You can put in a custom xorg.conf file in /etc/X11

Card?
Driver?

in termenal type lspci this will show all your hardware and chips.
but if you told use the distro or if it was kde or gnome etc we could help. some distros use also lsdev. some you need to sudo some you dont so little help please.

Wish I knew what card and driver was in here. That's why I asked about finding system info.

In the output of
#lsmod

look for i810 or i915M (the driver)
if it is not there

then

#sudo modprobe i810.o

or

#sudo modprobe i915m.o

If it is edit

#sudo kate /etc/X11/xorg.conf



based on (Do NOT Copy blindly)



# 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 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
# again, run the following commands as root:
#
# cp /etc/X11/xorg.conf /etc/X11/xorg.conf.custom

See http://www.autistici.org/blicero/vai...nstall-en.html too (the machine is different, but xorg.conf will match )

or you can install Fedora-10 in parallel for a multi-boot system

Thank you amani. The command that worked in Bash was what Drakeo suggested. It did not work with sudo. Do I leave out the sudo part on the commands in your previous post?

sudo is for root privileges.

without that you cannot edit things outside /home/user
modprobe will need it


lsmod, lspci can work without that

This may be a KDE PROBLEM

TRY THIS FIRST:

edit /usr/bin/startkde (in kate with root permissions)
comment out the line starting ksmserver (kwrapper4 ksmserver) (that is put a # in front)
Instead write
kwrapper4 krunner &
kwrapper4 plasma &
kwrapper4 kwin


Restart computer
