I can't say if the PFIFO_CACHE_ERROR is still present, because I can't get past this error to run any XWindows apps.

Those protection errors are expected... there's some minor difference between NV04 and NV05, and so those happen.... iirc...

This is with Tahrpup 6.0, with an updated kernel released by the maintainer of Tahrpup. The Xserver has no mouse pointer, and displays only vertical stripes. But ctrl-alt-F2 worked and I can still use the text screen console. Looked at

Oh, that's the issue. OK. At what point does the display become corrupted? Can you describe the corruption, and/or take a photo? -- You are receiving this

https://bugs.freedesktop.org/show_bug.cgi?id=28095 --- Comment #11 from Brent <bzipitidoo at hotmail.com> --- The display shows thin vertical stripes. The very top line is solid, the rest of the lines alternate between white and light gray. Best as I can make out, the stripes are 3 pixels wide. I do not see a mouse pointer. But if I move the mouse to the upper left and try a right

https://bugs.freedesktop.org/show_bug.cgi?id=28095 --- Comment #12 from Brent <bzipitidoo at hotmail.com> --- The display is corrupt at the start.

https://bugs.freedesktop.org/show_bug.cgi?id=28095 --- Comment #14 from Ilia Mirkin <imirkin at alum.mit.edu> --- So by the sounds of it, we broke the display stuff at some point between pre-history (i.e. before nouveau was in mainline) and... now. I'm fairly sure that it's a fairly self-contained problem -- my NV05 TNT2 M64 works fine (or at least did recently, I think I last

https://bugs.freedesktop.org/show_bug.cgi?id=28095 --- Comment #15 from Brent <bzipitidoo at hotmail.com> --- Yes, someone else said that hardware was unusual. But Nouveau did work with it, at elast somewhat, in the later 2.6 kernels. If it helps at all, the Diamond Viper V550 video card reports a version of 1.93E during POST. Tried older versions of Puppy Linux, and ran into other
