The simple answer is that (afaik) this particular hardware set of hardware has had trouble since kernel mode-setting was introduce. There is not going to be a git bisect-able place where the problem started happening. ... I do have a question for devs... I have been all over the initialization code and I cannot find a place where the sideport RAM is treated as distinct from the UMA "vram". Is this stuff set up by the atombios? Is there a way to see what hardware addresses ranges are assigned? Is there a way to fix the GART (table) if the bios is setting up overlapping or otherwise broken addresses for GTT, UMA and sideport vram? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/556782 Title: [rs690m] Graphics corruption with ati x1200 To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/556782/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
