I recently up-graded to X 4.0.3 as part of the upgade to debian
testing. Also kernel version 2.4.5. There were some things to sort
out, but all seems basically well at this point.
There's one glitch, though, that I'm still trying to resolve. I have a
Matrox G400 card and I'm using the mga driver.
In the XFree86 log, I get this:
(II) MGA(0): [drm] bpp: 16 depth: 16
(II) MGA(0): [drm] Sarea 2196+632: 2828
[drm] failed to load kernel module "mga"
(0): [drm] drmOpen failed
(EE) MGA(0): [drm] DRIScreenInit Failed
and in syslog:
Jul 18 12:19:17 toraigh kernel: [drm] The mga drm module requires the
agpgart module to function correctly
Jul 18 12:19:17 toraigh kernel: Please load the agpgart module before
you load the mga module
So mga_drm requires the agpgart kernel module. I have this module in:
/lib/modules/2.4.5/kernel/drivers/char/agp/
The device file exists:
crw-rw---- 1 root video 10, 175 Jul 18 12:22 agpgart
But all attempts to load the module fail, with this on the
command-line:
init_module: No such device
and this in sys.log:
kernel: Linux agpgart interface v0.99 (c) Jeff Hartmann
kernel: agpgart: Maximum main memory to use for agp memory: 94M
kernel: agpgart: unsupported bridge
kernel: agpgart: no supported devices found.
lspci shows:
00:00.0 Host bridge: VIA Technologies, Inc.: Unknown device 0391 (rev 02)
00:01.0 PCI bridge: VIA Technologies, Inc.: Unknown device 8391
00:07.0 ISA bridge: VIA Technologies, Inc. VT82C686 [Apollo Super] (rev 22)
So I tried:
modprobe agpgart agp_try_unsupported=1
but got the same error messages. Anyone know of a way forward? Thanks,
Jim
