It is recommended to use the Red Hat Linux kernel which has been released as erratum. If you experience problems with it you believe to be bugs, file bug reports in bugzilla please. >I suspect that the problem is caused by the improper AGP Videocard >Driver.

There is the agpgart module, which is used by DRI supported drivers. The video drivers themselves work with PCI and AGP hardware, there is no separate driver for each. >I found a driver for VIA ProSavage PM133 on www.soltek.com.tw an also at >https://ranger.s3graphics.com/395drv/ but is writted for an old XFree86 >version (3.3.6) (i downloaded s3savage-1.0-15.tar.gz) Both are extremely ancient and useless. >So, my question is: Can be configured somehow this Videocard to keep my >sistem working correctly in Xwindows?

I'm not sure if the driver officially supports that. >I try to use: modprobe agpgart agp_try_unsupported=1 and, AGP driver >found but is not working corectly (i test it with TuxRacer Game)! That wont work, because the Savage driver is 2D only. There is no DRI 3D accleration support for Savage hardware, and so agpgart does nothing. For DRI supported hardware, the X server automatically loads the agpgart driver and the hardware specific DRI module, so you never need to do so yourself. However, unfortunately there is no DRI module for savage hardware currently so you're out of luck for 3D. >See below the kernel message > >Tail -f /var/log/messages > >Jun 14 13:19:29 dev04 kernel: Linux agpgart interface v0.99 (c) Jeff >Hartmann >Jun 14 13:19:29 dev04 kernel: agpgart: Maximum main memory to use for >agp memory: 79M >Jun 14 13:19:29 dev04 kernel: agpgart: Trying generic Via routines for >device id: 0605 >Jun 14 13:19:29 dev04 kernel: agpgart: AGP aperture is 64M @ 0xe8000000 That just shows that you've loaded the agpgart driver into memory. That is a motherboard chipset driver, not a video driver, so it will load. However it wont do anything useful, since XFree86 wont use it for your card, as it is unsupported as I mentioned above. If you're having lockups and problems with the Savage driver, it is highly recommended to report such problems to the xpert@xfree86.org mailing list, and to Tim Roberts <timr@probo.com> whom is the Savage driver maintainer. Tim may be able to troubleshoot and possibly fix the driver if he is able to reproduce the problem you are experiencing. There is aparently a project which aims to create DRI support for the Savage, but to my knowledge it isn't ready or publically available yet. Good luck, TTYL -- Mike A.
