Ok. Scratch the idea then ;) > As I wrote in private, perhaps a full Cirrus "reprogramming" could be > necessary in the guest, after resume. Yes. In theory cirrus_crtc_mode_set() should do exactly that. In practice this function seems to be thrown together using the "tweak until it works" method, and it is incomplete. Doesn't trip up in testing in case vgabios initialized the cirrus, but hits after S3 resume. So I guess we have to wade through the cirrus init code in vgabios and find the init steps missing in cirrusdrm ... cheers, Gerd ------------------------------------------------------------------------------ Subversion Kills Productivity.
