Yeah, sounds like you've been working on this at LEAST as much as I have lol. First off, you're definitely using Powermizer, it's built into the driver. What it does is adaptively underclock your video card to save power when on battery. In our case, it limits the video card's core and memory clocks to less than half of their potential by force. If you run nvidia-settings, you can actually see that your clocks are at 200/100 instead of 799/500 (which is retardedly slow). You can get a significant boost of performance if you upgrade from the 185 series of drivers to the new 190 beta series (which I'm using and have no issues with). These have an option to go from 'Adaptive' clocking to 'Maximum Performance', allowing us 'battery users' to get from 200/100 clocks to 275/301 (Yay, half power!). Stuff should be smoother for you, at least.
As for an easier way to compile the kernel, under Ubuntu I'd recommend KernelCheck. It's a GUI program that will download the latest version of the kernel, compile it for you, and even let you set the options. The only thing is that it isn't the default Ubuntu kernel, it's the raw source. However, it will also allow you to choose what kernel version you want to use. So you can compile, say 2.26.29 or 2.26.30 (or even an older version of 2.26.31) with ACPI as modular, and still keep the newest 2.26.31-rc so that Ubuntu won't nag you about it. The only trouble that this produces is that it isn't compatible with DKMS, at least not from what I've seen. So once you install the video driver in that kernel, you'll need to uninstall either that driver or the kernel in order to install a newer kernel (which occurs quite often if you're using Karmic, otherwise it shouldn't be an issue). Also, I'm shocked to learn that DSDT had nothing to do with it. Everywhere else I've looked (http://www.nvnews.net/vbulletin/showthread.php?p=2050621) lists DSDT as a possible problem, but no one was brave enough to tackle it. Nice job on that. I guess this is just a kernel issue, then. And only in certain distributions. Weird. If you can't compile the kernel correctly with KernelCheck, I might need you to post that tutorial. I've only ever used KernelCheck once before, and it wasn't really even needed (I set a few options to optimize my CPU usage, that's about it). And yeah, the last time I tried openSUSE, the 'One Click' driver install kept 404ing. I was hoping I'd have better luck this time, but I think I'll try your solution first, so long as I know how. -- ac adapter is not detected https://bugs.launchpad.net/bugs/412499 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
