Intel 3D rendering problems

[Tideflat]

I am having trouble with 3D rendering on my integrated Intel GPU. (I think it is a 3000 something). For example many (but not all; for example Triangle, Speedmine or SBalls) of the 3D screen savers on XScreenSaver show up in black and white, as in only black and white. No grey-scale. Also Wings3D only shows a black screen where the 3D is supposed to be.


I just updated to the newer kernel that Shador packaged. (I have only booted up into it once.)

Here is the output of lspci.

Do you have any idea what the problem is?

Did those problems exist before you updated the kernel or after or both?

[Tideflat]

The problems existed both before and after I updated the kernel. When I updated the kernel it only fixed all of the other hardware problems. Which was very nice but not what I was looking for.

I just discovered another oddity, "Queens" renders fine but "Endgame" is missing the board and the shader doesn't work right. (Same black and white problem.)

I am testing with screen savers simply because that is what I have installed on my computer. If there is some other program that I can use to test with that would be more helpful I am willing to try it.

Thank you for helping by the way.

I'm sorry, but I really have no idea why you're having these problems. It could be that your graphics card is too new and not properly supported by the kernel/xorg yet. Have you tried any other distributions? Do you have the same problems there?

You could try disabling direct rendering. No idea if it help or not. Create a file /etc/X11/xorg.conf.d/20-intel.conf with the following contents:

Code: Select all

Section "Device"
    Identifier "intel"
    Driver "intel"
    Option "DRI" "false"
 EndSection

reboot and see if it helps.

It works! Thank you.
