Hello, I've been running myth for a few years now. I like it a lot! I recently tried to upgrade to 2.6.24 and also to <a href="http://2.6.24.4">2.6.24.4</a> and both times when I get into KDE and attempt to play a video, it's horribly slow. I just found out that my AGP is disabled by looking in the nvidia driver AGP status flag file. It reports:<br>
<br>Status: Disabled<br><br>AGP initialization failed, please check the ouput<br>of the 'dmesg' command and/or your system log file<br>for additional information on this problem.<br><br>I did a little poking around way long ago and I found that this is caused by the agpgart (kernel AGP driver) getting loaded instead of NvAGP (the nvidia AGP driver). When I look for 'AGP' in dmesg, I found these messages:<br>
<br>NVRM: loading NVIDIA UNIX x86_64 Kernel Module 169.12 Thu Feb 14 17:51:09 PST 2008<br>NVRM: not using NVAGP, kernel was compiled with GART_IOMMU support!!<br>NVRM: failed to allocate stack!<br><br>So I went back to my kernel source and I cannot deselect the agpgart! It get automatically selected when I add PCI support. I had this problem long ago and I was able to solve it by putting 'Option "NvAGP" "1"' in my xorg.conf and 'agp=off' in my kernel line in grub, they are both still there but 'agp=off' no longer disables the agpgart from loading. How can I fix this? Am I doomed to use 2.6.23.xx indefinitely? Because it honors the 'agp=off' flag.<br>
<br>Thanks,<br>-Greg<br>
