I've wasted a lot of time with the mmio registers to find out why things go slow. But it seems it's something else.
Just loading the nvidia kernel module without starting X is enough to make nouveau go fast after kexec. I did an mmio trace while loading the module, but it only wrote 140 to 0, and that was all. I've checked the PCI config space, also nothing interesting. Any tips how to find out what happens? -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-nouveau in Ubuntu. https://bugs.launchpad.net/bugs/653714 Title: Garbage on X display w/ Dell D800 wuxga & nouveau driver (Nvidia GeForce4 Ti 4200 Go AGP rev a1 [NV28]) To manage notifications about this bug go to: https://bugs.launchpad.net/nouveau/+bug/653714/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
