intel 946GZ drivers

logicalfuzz · 07-17-2007, 08:57 AM

Hello,

I've recently installed CentOS 5 on my PC at work.

The problem is, my display shows a resolution of only 800x600. How can i get a better resolution? I dont exactly know what make the motherboard is. I am not allowed to open the cabinet... :-( But Windows XP on the same machine tells me its "Intel 946GZ Express".

Intel redirects me to http://www.intellinuxgraphics.org, which has a wierd way of downloading the driver.. which shouldn't have been a problem if i had the package for git-clone installed (which again leads me to the dependency hell.. perl module compilation one.. argh!!)
Is it not possible to configure the display for a better resolution using VESA drivers?

or better still... is there an easier way to download the intel driver?

There is a way to get these chips to work in something other than "framebuffer" mode. Have a look at this thread: http://www.suseforums.net/index.php?...ic=27873&st=20

The short version is that you'll need to be root and run xorgconfig to tell the system to install the "i810" driver. The 810 is an earlier Intel chip, but the driver works with our 946GZ chips too. I used this to get out of framebuffer and 800x600 into 1280x1024 on an LCD monitor, and the screen and all that works okay now.

Hope this helps.

The solution to your problem is to install the 915resolution package. I had the same problem with my 945GZ motherbord, after installing this package it solved my problem. I used this package on Debian, Ubuntu and Mandriva and it always solved the resolution problem

walla299,
Seems CentOS does not support this command "xorgconfig". And in addition, when i open the xorg.conf file, i see the following entry <posting the complete xorg.conf file>:

Code:

# Xorg configuration created by system-config-display

Section "ServerLayout"
        Identifier     "single head configuration"
        Screen      0  "Screen0" 0 0
        InputDevice    "Keyboard0" "CoreKeyboard"
EndSection

Section "InputDevice"
        Identifier  "Keyboard0"
        Driver      "kbd"
        Option      "XkbModel" "pc105"
        Option      "XkbLayout" "us"
EndSection

Section "Device"
        Identifier  "Videocard0"
        Driver      "i810"
EndSection

Section "Screen"
        Identifier "Screen0"
        Device     "Videocard0"
        DefaultDepth     24
        SubSection "Display"
                Viewport   0 0
                Depth     24
        EndSubSection
EndSection

Does this not mean, that i am currently using i810 drivers? In addition, when i switch from init 3 to init 5, or vice versa, sometimes the screen goes blank.. no activity.. and it never comes back. Has this something to do with the display driver?

Yves,

The command "915resolution -l" throes the following error...

Code:

[root@localhost ~]# 915resolution -l
Intel 800/900 Series VBIOS Hack : version 0.5.2

Intel chipset detected.  However, 915resolution was unable to determine the chipset type.
Chipset Id: 29708086
Please report this problem to stomljen@yahoo.com

edit: Ubuntu/Debian seem to have the right packages available (xserver-xorg-video-intel). Deb packages are available for this. The readme in this tar file says this driver supports intel 946GZ chipset. However no rpm packages are available yet. And compilation of this source package lands me up in C file errors..
