Previously, Linux could boot with either GPU but couldn't bring the discrete GPU back after the integrated GPU was selected, forcing users to either accept a 12W idle power cost from the unused discrete GPU or lose access to it entirely. The fix spans apple-gmux, amdgpu, and the HDA controller, enabling proper power lifecycle transitions, DRI_PRIME offloading, external monitor support, and suspend/resume, tested over three weeks on both MacBook revisions. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### How do I fix the discrete GPU not coming back after boot on a 2018 or 2019 MacBookPro15,1 running Linux? Patches posted to the Linux kernel mailing list by Andre Eikmeyer add the missing power lifecycle support across apple-gmux, amdgpu, and the HDA controller, letting the discrete GPU return after being powered down by GMUX. With the integrated GPU set as primary at boot, the discrete GPU can then transition between DynOff and DynPwr states, enabling DRI_PRIME offloading and external monitor support, tested over three weeks on both 2018 and 2019 MacBookPro15,1 revisions. _Track this hybrid graphics fix on daily.dev as it moves through kernel review toward mainline._ ### How much power does the unused discrete GPU waste on a MacBookPro15,1 running Linux? Roughly 12 watts of idle power draw is attributable to the discrete GPU sitting unused when Linux boots with it as the primary GPU, out of about 24 watts total idle draw on the MacBookPro15,1. Selecting the integrated GPU at boot avoids that cost, but until now the discrete GPU could not be brought back up afterward, blocking hybrid graphics and suspend. _Linux users chasing battery life gains on MacBook hardware can follow fixes like this on daily.dev._ ## Similar posts on daily.dev -
