Intel Extreme Graphics running as 640x480

**tjcw** · 02-25-2004, 02:26 PM

I have an 'Intel Extreme Graphics' chip (82845, supported like i810) in a machine with 2 GB of memory. When I boot knoppix, I get a message to the effect that the 'insmod' for i810 fauls becuase 'agpgart' has a memory allocation error; and the X-server runs in 640x480 mode.

My monitor is capable of everything up to 1600x1200.

What do I specify to get my video hardware working to its capability ?

I increased the 'AGP memory' in the BIOS settings to 8 MB, and the aperture to 128 MB. I still get the error message, but now I get an 1024x768 screen.

I get 'i810: Unknown symbol cmpxchg' from char/drm/i810.ko when trying to run the c't knoppix26.

So, better, but not perfect. Can I tell if I am running 'accelerated' video ?

I had exactly the same problem running Knoppix 3.2 - neither my on-board graphics or on-board sound was working.

However, both seem fine in 3.3

Now, the power managment doesn't work; which isn't so important.

(I ought to run Knoppix again, and retrieve the specific error messages and post them here, instead of just whinging at my colleagues.)
