intel 865 problems

I have the i865 intel on board graphics but have no 3d acceleration. I tried to use the patch for the i915 module but after running "sh install.sh" I got the message that DRI drivers cannot be installed without the latest kernel modules. But I am up to date with everything.

Re: intel 865 problems

the i915 in arch's stock kernel (current) should work perfeclty. if it doesn't for you, see what /var/log/Xorg.0.log says. else i suggest to increase the amount of memory shared for the card or lower you resolution / bpp. if that all doesn't help try to force DRI:

Option "DRI" "true"

i expect that you took a look at the default DRI section in xorg.conf though.  wink

Re: intel 865 problems

This is a long log file so I guess I can't stick it here. Before I didn't have dri enabled, which didn't matter because I didn't need 3d accel, now it is but it enabled glxinfo reads....

The resolution is fine for this card. By increasing the amount of memory shared do you mean to change this in BIOS?

Re: intel 865 problems

1) you did load the GLX module in xorg.conf, right? (the line above the one with dri)

2) DRI needs extra memory (no idea what exactly is behind this as my knowledge isn't that deep), so it might be that if you for instance have allocated 8MB for the card in your bios. if you then try to run 1280x1024-24 (possible) there might not be enough left. so it's a good idea to increase the ammount of memory. twice of what you expect your desktop resolution to take up is always a good idea.

my xorg.xonf snippet:

Section "Device"
        Identifier   "Intel"
        Driver       "i810"
        #Driver       "intel"  # package is on the aur ;-)
        VideoRam     32768
        Option       "DDC" "false"
        #Option       "VBERestore" "true"
        #Option       "Rotation" "270"
        #Option       "Xvideo" "true"
EndSection

Section "Screen"
        Identifier "Screen"
        Device     "Intel"
        Monitor    "Monitor"
        DefaultDepth   16
        SubSection "Display"
                Depth     16
                Modes    "1366x768"
        EndSubSection
EndSection

Section "DRI"
        Group "users"
        Mode 0666
EndSection

and a snippet from a successfully enabled DRI:

        Screen to screen bit blits
        Solid filled rectangles
        8x8 mono pattern filled rectangles

Re: intel 865 problems

I got the dri working and have 3d.....a little. I ran glxgears and get fp of 340 fps. So the only 3d I could get off my box would be to lose sleep for a few days and then stare at my computer.

Anyhow, is this all I can expect to get.

Re: intel 865 problems

I did try the scitech driver which was more beautiful but no 3d.

Re: intel 865 problems

the intel chipsets are not meant for gaming. primarily they're general purpose highly integrated components which are - relatively - cheap to get. so it's not unusual to get so few fps i'm afraid.

i'd suggest to get the inofficial X11R6 driver made by intel a go though. it just might make a difference.

Re: intel 865 problems

Of course you are right. My box is built for work. It was cheap and runs fairly well. I designed it for office work and that is what it does.

In most other areas I have been able to do much better with Linux. It kind of bothers me that I can't run NWN better under Linux than Windows.
