Thanks to Geert for pointing out you can't change virtual resolutions on the fly with XFree (I was about to try! ;-) You then asked me to look at getting it to work without using the FBDev. Given my earlier patch which calculates XCLK using OF supplied values in the pll registers, all you need to do to use it without FBDev is to simply comment out the calls to vgaHWSave and vgaHWRestore in r128_driver.c. >>From that point on, everything works like a charm. My question is as follows, under ppc should we ever be doing anything with vgaHWSave and vgaHWRestore. Can I simply ifdef them out for all __powerpc__ machines? If not, is there any way to determine under which powerpc machines that an r128 card actually can use vgaHWSave and vgaHWRestore. I think the only outstanding issue on r128 is the damn flashing white square when cursor images are changed. I have looked and looked at this but I can't figure out why this is happening unless a big white square is someone's idea of a transparent cursor! ;-) I have to start spending time on some other projects for awhile (i.e. real life research project that needs to get underway) so I wanted to wrap things up with the r128 driver for awhile. If and when I get some time, I would be happy to take a shot at taking the r128 source and making it a mach64 source just in case you think that would be of use (i.e. someone else hasn't done that yet and the old ati driver has not been converted to work yet).
