resolution problem

ekamlesh · 09-27-2008, 06:58 AM

Respected Linux experts,
I have installed Debian Etch on my system which has Intel DG31 PR motherboard (G 31/33 chipset). My monitor is Samsung 943NWX, it has 1440x900 @60Hz optimum resolution.Installer selected vesa card and gave a resolution of 1280x1024@75.I tried to reconfigure xorg.conf with dpkg and select i810 but that did not work. Then I made suitable changes in my xorg.conf file which now gives 1024x768@60Hz resolution. I tried to load modules agpgart, i915, intel_agp, drm and then reconfigure xorg.conf to use i810, but that does not work.After loading the modules glxinfo gives the out put direct rendering : No. I then installed Ubuntu 8.04.1 which automatically detected my screen's resolution and it is fine. But Ubuntu's xorg.conf does not give any information. It just says configured monitor, configure screen etc. Here is the relevant portion from Debian's xorg.conf

Backup your "xorg.conf" to something like "xorg.conf-20080927". Add "1440x900_60" to the start of each of your "Modes" lines in xorg.conf. Reboot or restart X using "Ctrl-Alt-Backspace". Tell us if it works.

ekamlesh · 10-02-2008, 06:48 AM

Thank you for your response, sorry I am late in replying.But your suggestion failed to give a positive outcome. Xorg.log file says that vesa does not support 1440x900. Thank you again for your answer, if there is any other way out please let me know.

farslayer · 10-02-2008, 07:20 AM

First thing you need to do is select the right video driver. what is the output of lspci

adding 1440x900_60 to your xorg.conf, won't do anything for you right now, because that is referencing a modeline that isn't in your configuration. You could certainly add a modeline if necessary, but first we need to get you off the generic limited vesa driver and onto the proper video driver.

My bad. I did not notice the

Code:

Driver "vesa"

line.

farslayer is correct, you need the driver for your card. Please post the output of "lspci" and "lspci -n".

That's not very useful.. we need to fix that first. Run the following command.

update-pciids

Then post the output of lspci again please.

lspci -n gives the following output
00:02.0 0300: 8086:29c2 (rev 10)

Unfortunately, that device is not supported by the latest stable kernel (2.6.26.5 at the time of this writing). You might want to buy a supported add-on card.

Your other alternative is to search the Intel web site to see if they have released an out-of-kernel driver for the VGA adapter in your chipset (82801G).

ekamlesh · 10-05-2008, 12:27 AM

Thank you farslayer and David1357.
update command did not work beacause my Linux machine is not connected to the net. But output did give me a clue. I replaced my pci.ids file manually in /usr/share/misc/. Here is the first three lines of the out put from lspci command. Other lines remained unchanged and hence I am not posting those lines.

00:00.0 Host bridge: Intel Corporation 82G33/G31/P35/P31 Express DRAM Controller (rev 10)

00:02.0 VGA compatible controller: Intel Corporation 82G33/G31 Express Integrated Graphics Controller (rev 10)

Please guide me furthur. Thank you again.

The info I found indicates that Graphics controller should work with kernel 2.6.22 or newer..

Debian Etch is 2.6.18

Debian Lenny would probably work fine with it (2.6.24 on install 2.6.26 after update)

Could you provide a reference? I schlepped through the code for 2.6.26.5 and I could not find support for that device.

I wish they would keep the device ID definitions in header files. I finally found the definition for ekamlesh's hardware:

Code:

#define PCI_DEVICE_ID_INTEL_G33_IG          0x29C2

in "linux-2.6.26.5/drivers/char/agp/intel-agp.c". So it looks like an upgrade to Debian "Lenny" is a good solution. I would personally compile a custom kernel from the latest source, but I like doing that.

ekamlesh · 10-17-2008, 11:26 PM

Thank you farslayer and David1357, I will install Lenny beta 2 today and tell you about the outcome. I was not knowing about Lenny.Thanks again.

farslayer · 10-17-2008, 11:51 PM

All you really need to do is upgrade etch to lenny..

edit your sources list and change all entries from stable or etch to lenny

BEFORE

Code:

debianetch:~# cat /etc/apt/sources.list

deb http://ftp.uwsg.indiana.edu/linux/debian/ etch main contrib non-free
deb-src http://ftp.uwsg.indiana.edu/linux/debian/ etch main contrib non-free
deb http://security.debian.org/ etch/updates main contrib non-free
deb-src http://security.debian.org/ etch/updates main contrib non-free
deb http://www.debian-multimedia.org etch main

AFTER

Code:

debianetch:~# cat /etc/apt/sources.list

deb http://ftp.uwsg.indiana.edu/linux/debian/ lenny main contrib non-free
deb-src http://ftp.uwsg.indiana.edu/linux/debian/ lenny main contrib non-free
deb http://security.debian.org/ lenny/updates main contrib non-free
deb-src http://security.debian.org/ lenny/updates main contrib non-free
deb http://www.debian-multimedia.org lenny main

then update and do the upgrade..

Quote:

If you are running stable (aka Etch), you could consider upgrading to Lenny and see, if everything works fine. Currently there are no detailed release notes documenting the procedure, so you best way to test upgrades are to:

1. Make backups
2. Change your /etc/apt/sources.list
3. Run aptitude update to get information about new packages
4. Run aptitude install dpkg aptitude apt to install the newest package management
5. Run script aptitude full-upgrade
6. Exit the environment of the script command, by typing exit

If something goes wrong / something unexpected happens, please report it. If you already know a specific package, report a bug against that package. If you don't know, please report a bug describing the problem you experienced to the upgrade-reports package. If your problem is something, which can't be fixed properly, but should be documented (e.g. hardware support regressions, packages no longer available) please report a bug against the release-notes package (Bonus points if you not only report the bug, but also supply a paragraph to be added to the release notes).
The command script will log the entire output of the command in the file typescript. Should something go wrong during the upgrade, please send this file along with your bug report.
