Adjusting display

sunils1973 · 02-02-2009, 08:39 AM

In my debian system there is a slight flickering in the monitor

I corrected that issue in windows XP by increasing the frequency to 75
(This type of flickering is ther in 60HZ)

I think without having proper driver for the display card, it can't be done in debian[default vesa driver is installed]

For downloading and installing the correct driver, I have to know the graphic card details. How can I get it in debian?

as root:

Code:

lspci|grep VGA

If you want info about drivers and modules:

Code:

lspci -k

Send the output for advise about driver to use.

sunils1973 · 02-03-2009, 07:03 AM

sun:/home/sunil# lspci|grep VGA
01:00.0 VGA compatible controller: VIA Technologies, Inc. Unknown device 3230 (rev 01)

-k is not a valid swith for lspci command

su - to root and update your pci.ids file

update-pciids

Try your commands again.. and -k is a valid switch for lspci in Debian.

also
cat /etc/X11/xorg.conf | grep -i driver

sunils1973 · 02-03-2009, 11:39 AM

cat /etc/X11/xorg.conf|grep -i driver
Driver "kbd"
Driver "mouse"
Driver "vesa"

-k is still not working

In /etc/X11/xorg.conf, try replacing
Driver "vesa"
by
Driver "via"
so the via X module be used instead of the generic (vesa) one.

[EDIT]There is also a kernel module for the via graphic card. If 'lsmod|grep via' return nothing, load the module by hand. As root: 'modprobe via'.

Then try to start X.

if the via driver isn't installed by default you can install it.. although my system shows this as a driver that is 'A' automatically installed with the system

Code:

user@it-lenny:/usr/src$ aptitude search ~i | grep xserver-xorg-video | grep via
i A xserver-xorg-video-via          - X.Org X server -- VIA display driver

It could also be the openchrome driver, but you haven't showed us the output of lspci after updating your pci.ids file as directed, so we can't tell what video card you have from where we are sitting..

Code:

usr@it-lenny:/~$ aptitude search chrome
p   xserver-xorg-video-openchrome                            - X.Org X server -- VIA display driver

Looks like a good possibility though.. 3230 K8M890CE/K8N890CE [Chrome 9]

Now update that pci.ids file already and verify this..

update-pciids

if it confirms you have the Via Chrome integrated graphics which I believe it will, install the driver

aptitude update
aptitude install xsrver-xorg-video-openchrome

then edit your xorg.conf and change 'vesa' to 'openchrome'
or run
dpkg-reconfigure xserver-xorg

and set the driver using the reconfigurtation wizard (I find editing the file directly to be easier and faster)

sunils1973 · 02-04-2009, 09:00 AM

sun:/home/sunil# lspci|grep -i vga
01:00.0 VGA compatible controller: VIA Technologies, Inc. K8M890CE/K8N890CE [Chrome 9] (rev 01)

lsmod |grep don't return nothing

farslayer · 02-04-2009, 09:49 AM

confirmed, try the openchrome driver for your video.

sunils1973 · 02-05-2009, 09:19 AM

but how?

sun:/home/sunil# apt-get install xserver-xorg-video-openchrome
Reading package lists... Done
Building dependency tree... Done
xserver-xorg-video-openchrome is already the newest version.
You might want to run `apt-get -f install' to correct these:
The following packages have unmet dependencies:
xserver-xorg-video-openchrome: Depends: libc6 (>= 2.7-1) but 2.3.6.ds1-13etch7 is to be installed
Depends: libdrm2 (>= 2.3.1) but 2.0.2-0.1 is to be installed
Depends: xserver-xorg-core (>= 2:1.4) but 2:1.1.1-21 is to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

Did you try this ?

could you post the output of
cat /etc/apt/sources.list

Not sure why you are receiving those dependency errors, but I'm going to guess the CDROM you used for install is not commented out in your sources list.

It says it needs packages from Debian (testing) to meet the dependencies, but it's trying to install packages from Debian (Stable)

TESTING
xserver-xorg-core (2:1.4.2-10)
libc6 (2.7-18)
libdrm2 (2.3.1-2)

STABLE
xserver-xorg-core (2:1.1.1-21etch5)
libc6 (2.3.6.ds1-13etch8)
libdrm2 (2.0.2-0.1)

You need to fix your sources list, then apt-get update && apt-get upgrade to resolve those issues before moving forward.

Notice how the CDROM (that is labeled Etch) is Commented out in my list ?

then I replace via with vesa

OK that makes no sense.. if that is your sources list why is the openchrome driver asking for Lenny dependencies ? ? ?

Could you post the output of

apt-cache policy xserver-xorg-video-openchrome

Lets see where this driver came from
