Cursor Issue in Blender on Linux using NVidia Drivers

To start off:
OS: Linux: Knoppix on Hard Disk (KDE): Recompiled 2.4.26 kernel for nvidia support
Video Card: GForce4 MX 440 w/ AGP 8x
Latest drivers? Yes; compiled into kernel about 1 week ago and enabled in XF86Config-4
Mouse shadows? No, already turned them off according to directions
AA turned off? I turned it off but the problem was not fixed; it is on again, but not blurring blender.
Color depth? Currently 24; 32 is unsupported by Nvidia’s driver and 16 didn’t fix the problem.
Tried different window program? Yes, but Afterstep and Gnome had the same problems

Ok, the issue is that when I open menus with the space bar, my cursor has a rectangular (the color of the background of blender) trail behind it; often, an image of the cursor is left where the cursor was when I opened the menu. I’m using blender 2.31, but 2.34 had the same problem. The giltch also affects when I move the cross hairs, often deleting all but the very tips of the cross hairds. When I open blender in full screen, the problem is worse as my cursor is completely invisible when in the 3d window (though it’s visible in the menus at the top and bottom).

Anyone have any ideas?

Can you post your XF86Config-4 file and the output of lsmod. It’s really hard to see what might be wrong without seeing those. Some other info that might help

  1. how do you start X – from console or kdm
  2. are you seeing the nvidia splash screen
  3. did you compile the kernel and nvidia module yourself

I have a machine with the same kernel (although I don’t know what patches lnoppix uses) and video card here and it works perfectly so we should be able to get it working on your box if it isn’t flakey hardware.

  1. KDM starts X
  2. Nvidia splash screen does appear
  3. Yes, I compiled the Kernel through the Nvidia utility from their site.

Here goes some huge posts:

Ok, from what you posted it looks like the driver is loading correctly and your video settings are the same as mine except here:

sw_cursor is needed for some ati and radeon cards

Option “sw_cursor”
#Option “hw_cursor”

where you have a sw_cursor I use a hw_cursor.

I’m hoping that this will fix your problem, if not, the next thing I would check is your “agp” setting.

Believe it or not, that fixed it. Thanks so much.
