Installing 10.10 - Graphics Problem

[chetkgp]

Hi All,

The live Ubuntu 10.10 cd works fine on my laptop
and is able to detect and configure my graphics card.
But the installation of Ubuntu on my laptop fails to do so.

Is there any way to obtain the same graphics settings from
the live cd to the installed Ubuntu.

What graphics card do you have?
If you have a nvidia or ati card, have you installed the proper drivers (system > administration > hardware drivers) for your card?

Did you install Ubuntu inside Windows using Wubi? Or is this a real install to a linux partition on your hard drive?

My laptop has Intel's P6100 processor and
my graphics card shows

00:02.0 VGA compatible controller: Intel Corporation Core Processor Integrated Graphics Controller (rev 02)

Does Intel provide a driver for Linux for this chip ?

I did a fresh installation of Ubuntu not Wubi

Ubuntu already includes the intel graphics driver.
Are you able to get to the graphical desktop at all after installing Ubuntu 10.10? Or is it a problem with not getting the proper resolution for your monitor? What exactly happens when you boot to the desktop?
If you can not get to the graphical desktop, then boot to recovery mode and choose the option xfix fix video (or whatever it says exactly). Then reboot.
If that does not work, then try adding i915.modeset=1 or i915.modeset=0 to the kernel line when booting Ubuntu. This will disable the kernel mode setting for intel graphics.

After the 10.10 installation when I rebooted the laptop, gdm was unable to start.
I just a got a text mode login window.

I then added an xorg.conf file with a vesa driver and did a startx. This got me
a GUI with a bad resolution. Also it periodically logged me out of the GUI.

I have tried the booting with the i915.modeset=1 turned on but that fails to
solve the problem.

You can also try booting with the boot option i915.modeset=0.
Also, instead of trying to start the GUI with startx, try running:

sudo service gdm start

What specific intel graphics chip does your laptop have?

Tommcd,
I have the same problem and tried the 'sudo service gdm start' and get a black screen and no response.

I cannot find what type of graphics card I have. I looked in the Dell Setup menu, but found nothing. I am going to the Dell service site now to look the information up.

Is this a fresh install of Ubuntu? Or did you do a dist-upgrade from 10.04? How did you install Ubuntu?

To find out what graphics card you have, run lspci like this:

lspci | grep -i vga

And post the output here.
