Hello all, It has been a long time since I touched FreeBSD last... but I recently got a PowerMac G5 (because!) and FreeBSD seems to be the only reasonable choice these days for such a machine. So... I'm back here :) First of all, and to be honest, everything has worked better than expected. I could get the system installed without trouble and I've been surprised to see that there are now pre-built binary packages for powerpc64 available out of the box! A very nice surprise. Last time I tried this on a similar machine 7 years ago, I remember having to build a ton of stuff from scratch, which wasn't fun... So... I have installed X.org and, on the first attempt to run it, I got the following video output: https://photos.app.goo.gl/R1bx4FCRD7aRKG9x9 Note that the colors are all off and that half of the screen is "strange": the background is split in two colors. This picked up the scfb driver. This machine comes with an NVIDIA 6600, so I manually installed xf86-driver-nv to give it another try. With the nv driver, I got this: https://photos.app.goo.gl/U7Yx3zs2YfND25ks7 In this case, the colors are good and things mostly work... but note that the background problem is still there. And if I maximize something like xterm, the same thing happens: the top of the window has the right white color, but more than half is black and has some rendering artifacts: https://photos.app.goo.gl/kWacbVNXAB8cpqHJ9 Lastly, with the nv driver, when I exit Xorg I'm left with a console with extremely faint text. There is no brightness. Here is the X.org startup log: https://pastebin.com/srgPiUiu Any thoughts or things I could try? I remember the other machine I had years ago had this same card and gave me some trouble too, because I remember buying a Radeon to replace it. Maybe I should do the same thing now? :-/ Thank you! -- jmmv.dev
