Hello, Recently I installed XFree86-3.3.6 and Utah-glx (on 4.2-BETA), both using ports. I'm loading agp.ko at startup (in /boot/loader.conf) and did a 'sh MAKEDEV agpgart' in /dev. At startup, an agp0 device is detected. X is configured to run at 16bpp, 1600x1200 on a Matrox G400 card with 32MB. I browsed the glx.conf file and found the defaults OK for me. When starting X (using xdm), the log shows a lot of [mga] lines. It shows some AGP related stuff and ends with waitForDmaCompletion: still going! PRIMADDRESS is 0xdc005a74 END 0xdc3fb7f6 SECADDRESS is 0x0 END 0x0 SETUPADDRESS is 0x0 END 0x0 STATUS is 0x80000020 xdm error (pid 271): IO Error in XOpenDisplay xdm error (pid 267): Server for display :0 terminated unexpectedly: 1536 xdm error (pid 267): Display :0 cannot be opened xdm is restarted several times but always fails. The screen is black and I need to log in through the network to reboot the machine (thereby resetting the video card). If I do not load agp.ko, the log complains about the agpgart device not configured, but starts OK, and rendering works more or less. It's a lot faster then software-Mesa, but my impression is that a G400 could do faster. Playing linux Unreal Tournament, the framerate is far below the performance of the Voodoo2-SLI that I also have in the machine (a factor 2 or so). Is it possible to get agp going with Utah glx? Would it be useful to increase the performance? BTW: on the same machine I had XFree-4 with agp and DRI going fine, so I assume resources are OK. Before going to XFree-3 I removed XFree-4 and Mesa (compiled via port with XFREE86_VERSION=4 option, to install some additional libs). If additional info is needed, I'll do my best to provide it ;-).
