Video card problem


Hi, i have a problem with my video card on my laptop. In particular when i configure xorg with the command xorgconfig i am not able to find any suitable driver for the chipset that is: Intel Corporation Mobile GM965/GL960. My OS is Slackware 12.0
When i launch the command lspci, it returns:

what should i do to make my video card working correctly? Now i can set it to 1280x800 but the refresh rate of the monitor goes up to 60Hz, that is low...
Thanks to all.

What driver are you currently using ? Check your '/etc/X11/xorg.conf', it's either vesa or intel. What type of monitor do you have ? If it's LCD, 60 Hz is not low, it's regular.

One thing you could try is enabling direct rendering (not sure how well this will go):

I choose the Intel 810 chipset while configuring with xorgconfig.
Yes the monitor is an LCD and 60Hz is correct, but when i run a window manager like xfce or kde, it seems that the colors are opaque and fonts are too much aliased, should i change something in the appearence of that window manager as well?

Thanks.

What is the native resolution of the LCD screen ? That's usually the best resolution to run it at.

So, is direct rendering enabled, it may allow you to choose higher settings. So run:
Code:
glxinfo | grep direct
it should say 'direct rendering: Yes'. Then you can try upping the refresh rate to 75 Hz or so, but you should probably lower the resolution, I doubt your monitor is capable of both. Do you have the manual for the LCD ? It should have data on refresh rates and corresponding resolutions supported.

This is the output of the command glxinfo | grep direct:

bash-3.1# glxinfo | grep direct
direct rendering: No
OpenGL renderer string: Mesa GLX Indirect


direct rendering is not supported, what can i do furthermore?

thanks

Follow the guide here to enable direct rendering:
http://www.linuxquestions.org/questi...in-x11-402003/

What about the manual for LCD monitor, it has important info, might wanna find it in the mean time if possible.

I don't have any manual with the specs in the shipment of the laptop. It is a Hp model: Compaq 6710s and the display is a 15.4 WXGA display. I caught the specs for this monitor running windows xp in dual boot and displaying the properties, so i am not shure if the parameters are correct: Horizontal refresh is 28.0-96.0Khz and Vertical refresh is 50.0-75.0Hz.

I followed the tutorial on http://www.linuxquestions.org/questi...in-x11-402003/
but Xorg doesn't enable direct rendering yet. I wonder why...

Yeah, unfortunately it seems that this particular version of Xorg may have problems with getting direct rendering on that card.

You don't actually need it, but I would think you could achieve higher refresh rates with direct rendering enabled, that way the load is put on the GPU not the CPU.

Try changing the following in your '/etc/X11/xorg.conf':
Code:
Section "Monitor"

    HorizSync       28.0 - 96.0
    VertRefresh     50.0 - 75.0

EndSection

Section "Screen"

    DefaultDepth    24

    SubSection     "Display"
        Depth       24
        Modes      "1280x800"
    EndSubSection
EndSection
I believe WXGA has native resolution as 1280 x 800, right ? that's what you should put as a mode.

I'am currently running with those parameters set, but i can't change the refresh rate differently than 60Hz.
I have tryied to change also the depth mode to 32 but X says that I830 driver doesn't support other then 24 bit.
There should be a solution for this i think. Maybe reinstalling the driver from the intel support site

thank you all.
