Unable to resolve 915GM resolution issue

samjaynes · 02-28-2007, 10:42 PM

I need your help and advice. I have googled, and read as much as I could before posting to this forum. As noted, I have the Dell Lattitude D610 (Ubuntu Edgy Eft) with the 915GM Video Card. I am limited to just 1024x768 resolution. Here are the steps I have done so far:

Installed 915resolution
sudo apt-get install 915resolution
sudo dpkg-reconfigure xserver-xorg
restarted xserver, but wouldn't come back from ctl-alt-f7, but ctl-alt-f1 went to a session.

Also, I have edited 915resolution MODE 30 to 1280 1024 32 (not being too picky at this point)
Changed the default to use mode 30 xres to 1280 yres to 1024 and bit to 32

Here is a some text from /etc/x11/xorg.conf:
Quote:

At this point, I am only allowed to select 1024X768 or 800X600 in System/Preferences/System Resolution... what am I missing?

Is their a repository that I am missing, driver, xorg stuff??? Any assistance would be helpful, I have seen quite a few threads both in Ubuntu forums, and other linux forums.

The modes may be limited by your monitor configuration. Have you tried selecting the proper monitor as opposed to generic? If your monitor isn't in the selection list, you should at least pick a generic monitor that can handle 1280x1024. That mode should be supported by the 915G video by default.

Also, since this is a laptop, it is highly possible that you are limited to 1024x768 by the LCD.

dlesaffre · 03-01-2007, 02:50 AM

I think you should at least have the "1280x1024" mode in your screens Modes lines.
And I am by no means an expert in X configuration, but you want 32 bit depth, but you don't have a 32-bit Display subsection. Maybe you should even adjust your DefaultDepth to 32. Or try everything with depth 24.

See /var/log/Xorg.0.log to see what's wrong and/or find the error messages in there and post them here.

Although targeted at Gentoo, a short HOWTO can be found at http://gentoo-wiki.org/HOWTO_Intel_O...ive_Resolution

@samjaynes

Most of the work has been done, now you just need to add one line of code and this issue will be sorted:

first edit the file bootmisc.sh:

Code:

$ sudo vi /etc/init.d/bootmisc.sh

Add the line 915resolution 3c 1280 800 after the line : [ -f /etc/default/rcS ] && . /etc/default/rcS (at approximatively line 10)
...

Code:

[ -f /etc/default/rcS ] && . /etc/default/rcS
915resolution 3c 1280 800

...

Evidently change the 1280 800 part to your desired resolution and where "3c" change it to your specified resolution. You can this find out by running in terminal the 915resolution hack and it should give you all available options:

Code:

sudo 915resolution -l

Just like everything else when it comes to tinkering back up everything worth backing up before attempting this. After the changes have been made, reboot.

This is part of a very useful guide from linux laptops: http://users.skynet.be/thomasvst/linux-on-laptop/

It was meant for a Vaio laptop but posses the very same chipset!

good luck

wabbalee · 03-01-2007, 07:44 AM

have you added a line in your either gdm or kdm file located: /etc/init.d/kdm ? as a first line you must put something like 915resolution 38 1280 800 24.
otherwise the hack will not load. check this thread http://www.linuxquestions.org/questi...d.php?t=496953 and this one http://www.linuxquestions.org/questi...39#post2503939 for more info, i have had the same battle with my Acer TM2480. everything is fine now.

Thank you for your response. I am unsure if the native resolution is 1024X768 (previously had XP), It very well could be on a 12.1" screen. However, I was hoping to force it to at least 1280X1024.

I know for a fact that an external 19" Dell LCD was able to produce 1280X1024 just fine when under the XP OS.

Thank you for your comments, as well as everyone else who has posted. I will make those modifications once I get back to the office.

GrueMaster · 03-01-2007, 04:34 PM

External monitor should, but I'm not sure how you would get there without some serious tweaks to the xorg.conf file. I know my nvidia supports different resolutions on different monitors, but it is a desktop system. I haven't been able to do the same on my 945GM based laptop.

Although it is confusing, I see:

I open this file, and could not see any code referring to the /etc directory. Everything began with /var... and no default directory either.

I hope I have the solution for you. If your LCD monitor is 17" or larger 1280x1024 should be supported at 60Hz.

I use Ubuntu edgy and have a 945GM card using the i810 driver.
915resolution need to be installed but you do not have to make any modifications its config file unless you want to use a wide screen resolution.

"sudo 915resolution -l" will give you the supported resolutions. If the one you want is in this list you do not need to alter any 915resolution files.

Here's what I did to get 1280x1024 enabled in Xorg.

What you will need to do is to create a modeline for the resolution you want to place in xorg.conf. To get a modeline you type this into a terminal "gtf 1280 1024 60 -x".

Edit /etc/X11/xorg.conf. At the end of the Section "Monitor" add Option "DDC" "false" and on a new line add the modeline that you got in the previous step, minus the -HSync and +Vsync. Like this:

Quote:

Section "Monitor"
Identifier "BenQ T705"
Option "DPMS"
HorizSync 30-65
VertRefresh 50-75
Option "DDC" "false"
Modeline "1280x1024" 108.0 1280 1328 1440 1688 1024 1025 1028 1066
EndSection

Note that gtf will give you a modeline that is called "1280x1024_60.00". This you will need to rename to "1280x1024" because it is not a valid name for xorg.

In the Section "Screen" set the DefaultDepth to 24 and you MIGHT need to add this line underneath the DefaultDepth: Option "MonitorLayout" "CRT" (I say "might" because I am not using a laptop but a DVI to VGA adapter to connect my LCD screen)

If "1280x1024" is not visible in the SubSection "Display" for 24 bit depth, add it before "1024x768"

Quote:

Section "Screen"
Identifier "Default Screen"
Device "Intel Corporation Mobile Integrated Graphics Controller"
Monitor "BenQ T705"
DefaultDepth 24
Option "MonitorLayout" "CRT"
SubSection "Display"
Depth 16
Modes "1280x1024" "1024x768" "800x600" "640x480"
EndSubSection

SubSection "Display"
Depth 24
Modes "1280x1024" "1024x768" "800x600" "640x480"
EndSubSection
EndSection

the device section should look similar to this:

Quote:

Section "Device"
Identifier "Intel Corporation Mobile Integrated Graphics Controller"
Driver "i810"
Option "XAANoOffscreenPixmaps"
BusID "PCI:0:2:0"
EndSection

I hope this have been helpful to you.

samjaynes · 03-07-2007, 12:49 PM

Thank you for your response. I made the modifications to the xorg.conf file, and x-server failed to start. The error I saw was:

No Matching Device Section for Instance
Failed to start... 0:2:1

No Video BIOS Modes for chosen depth

Here is a section of the xorg.conf file I created:

Code:

	SubSection "Display"

	EndSubSection
	SubSection "Display"

	EndSubSection
	SubSection "Display"
		Depth		24
		Modes		"1280X1024" "1024x768"
	EndSubSection
EndSection

Any ideas what would cause x-server to fail with these configs? P.S. I tried running x-server reconfig by after accepting the defaults, and choosing resolutions, it failed also.

Here is the output of 915resolution -l

Code:

Hello again,

First of all I see a typo in your xorg.conf. Modeline is called "1280x1024" but the corresponding mode in the screen section for 24 bit say "1280X1024" (note the capital X).
I recommend you to correct the typo and try again. If that does not help:

That error is a bit strange. Might be that BusID "PCI:0:2:0" in xorg.conf is wrong.

Let's see if you have more than one detected card. I would like to see the output of "sudo lspci | grep -i graph"

...and also I will need to see the full xorg.conf, not just parts of it. Do you have several cards/screens defined in there?

Thanks for the quick response, and your willingness to work through this mess. I changed the X to a lower case, and it still failed (BTW, how do you get to a terminal screen from the blinking cursor [I have been rebooting in recovery to execute the CP command])

My entire xorg.conf file is:

BUT, I think you may have something with the PCI. Here is the output of the lspci command:

Code:

BTW, In the xorg.conf file, when x-server fails, I see some errors regarding the fonts (but not mission critical at this point)

I saw this on the Dell site:
