[SOLVED] Intel 965 does not give correct resolution (1280x800)

AbtZ · 09:57 AM

EDIT: As of Ubuntu 8.04 the fix proposed further down is no longer necessary -- everything works fine out of the box. So if you have issues with graphics and your Intel 965 chip, it's unrelated to what is being discussed in this thread.

Hi,

I just bought a new laptop with an integrated Intel 965 graphics controller. The laptop came with Ubuntu already installed, with everything working fine... until I decided that I wanted to reinstall Ubuntu to get as "clean" an installation as possible.

Now my resolution is fubared. Gnome won't let me pick any resolution above 1024x768. The native resolution for this screen is 1280x800.

I tried downloading the 915resolution package. I tried changing the default color depth from 24 (which this card does not appear to support) to 16 bits. No luck.

Compiz does not work either, yet glxgears does.

The only thing that gives me the desired native resolution is if I edit xorg.conf so Ubuntu uses the Vesa driver instead. glxgears still works (at lower fps) but I still can't get Compiz Fusion to work, which is my goal ultimately.

The laptop in question is a Clevo MobiNote with an Intel Core 2 Duo T7500 @ 2,2GHz, 2 gb ram, and aforementioned Intel GM965 (X3100) Graphics Media Accelerator.

I have attached a pic of what my desktop looks like, running on the intel driver.

Any help?

I managed to fix it, with the help of the company who sold me the laptop. I'm posting the fix here, just in case someone else runs into the same problems as me.

1. Open a terminal.

Code:

sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf.backup

(makes a backup copy of your current xorg.conf)

2.

Code:

sudo gedit /etc/X11/xorg.conf

Copy the text below into the document you just opened.

Code:

# 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.
#

Save and close.

3. ctrl+alt+backspace to reload windows manager. If it doesn't work you can restore your old copy of xorg.conf through

Code:

sudo cp /etc/X11/xorg.conf.backup /etc/X11/xorg.conf

I'm not sure what exactly consitutes the "fix" in this xorg.conf (I'm just using the file they provided me). Maybe if I have a bit more time I will try to find out.

I am having this exact problem on my Gateway T-6815, so I will try to use your xorg.conf to fix it. I also think that I know why this happens ... it is a 'known issue' with version 1.2.0 (I think this is the right version) of xf86-video-intel from intellinuxgraphics.com.

From the README:
- Some GM965 systems, such as the Thinkpad T61, probe the TV as being connected
even when no output connector is available. This results in the gnome-panel
issue noted below.

And the issue noted below:
- gnome-panel is located in the middle of the screen. gnome-panel places
itself within head #0's boundaries, which doesn't work well with a second
head covering the same area as head #0 but larger.

Maybe the next release will not do this?

AbtZ

Good to know -- I guess then that it is the TVOutPut "Ignore" option that makes it function properly.

I hope it works for you.

It solved my problem, thank you!

For reference, I have a Gateway ML6720, running the 965 chipset, Intel X3100 gfx card.
Copying & pasting this part is what solved it for me:

I am having same problem with my toshiba u300-ns5.
intel 965.
Is there a way to find out if the monitor is the same name as listed here?
mine tells me it is just a generic lcd
or will 'lspci' give me the results?

AbtZ

"Allmän skärm" is Swedish for "Generic monitor". It doesn't matter what you call it.

From what I've gathered it's ignoring TV output that is important.

goodrench

well, that did it but after a reboot It goes back to the 4:3 resolution.
when I open the xorg.conf file I find that the line that reads

Quote:

Option "monitor-TV" "TVOutput"

is gone.
I have to add it to the file again and restart X.
Is there a way to make this stick?

AbtZ

Weird. If you save the file it should stick. Something must be changing your xorg file.

Try going through the steps I listed above again, after a fresh reboot. If it still doesn't work, try to figure out if you have some program running at boot that might alter your xorg file.

It's taken me all day and many false-starts to get this resolution thing sorted out. Thanks so much!!
