[Bug 435906] Re: need to turn off extra Switchable graphics GPU
If it would be possible to switch between graphics cards then consequently it would also be possible to turn off the one you don't need. It seems like there is a lot of effort being made for the master bug, I don't think another project will start just for this one as this is just a subset of the main project. What makes you think this is just a one-liner? There are many different laptops with many different graphics cards. -- need to turn off extra Switchable graphics GPU https://bugs.launchpad.net/bugs/435906 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Now in Maverick, vga_switcheroo is enabled, but the extra GPU is still powered on by default.

There are two BIOS settings: Switchable graphics and Discrete graphics. With the latter option, only the ATI GPU is in use, but with the former option, *both* GPUs are powered on by default. Neither of these options is good for battery runtime. - Fortunately, someone has found a solution that turns off the discrete - GPU in the switchable mode.

On the 8371G here, Switchable graphics originally gave some 2 hours of battery use, Discrete graphics gives some 3 hours of battery use, and Switchable graphics with this module loaded gives some 4 hours of battery use. The module doesn't re-apply the fix after resume from hibernate, so I've had to list it in the pm-utils - SUSPEND_MODULES variable. + On the 8371G here, Switchable graphics originally gave some 2 hours of + battery use, Discrete graphics gives some 3 hours of battery use, and + Switchable graphics with this module loaded gives some 4 hours of + battery use.

Adam, wrt bug #312756 support graphics card hot switch: Here in bug #435906, I'm not asking for hot switch -- what we urgently need is just that the extra GPU be turned off. I consider this a significant bug as these laptops are certainly not designed to power two GPUs at a time. Further, this is not something very complicated so I would've hoped for a fix earlier. It's even easier now that it's a one- liner :-) -- need to turn off extra Switchable graphics GPU https://bugs.launchpad.net/bugs/435906 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
