The discussion at the time was inconclusive, but in light of the strong possibility that we might not include i386 as a release architecture in 20.04 LTS, we took the proactive step to disable upgrades from 18.04 to 18.10 for i386 systems, to avoid accidentally stranding users on an interim release with 9 months of support instead of letting them continue to run Ubuntu 18.04 LTS with its 5 years of standard support. Last year, the Ubuntu developer community considered the question of whether to continue carrying forward the i386 architecture in the Ubuntu archive for future releases.
Note: this is an edited copy of my answer to this question, which may have useful pointers for your follow-on steps, as it is about resolving issues with the discrete card.Previous post (what follows is no longer accurate):Ĭross posted from the Ubuntu Devel Announce mailing list. It should only be needed on old (pre 2007) hardware. Update 2019 the package description for xserver-xorg-video-intel now recommends against installing the package. Sudo apt install xserver-xorg-video-intel That is alright, but you may want to keep xserver-xorg-video-intel installed (but see update below): sudo apt remove xserver-xorg-video-all This will trigger removal of the xserver-xorg-video-all meta-package, which by default is installed. Uninstall the Xorg nouveau driver sudo apt remove xserver-xorg-video-nouveau # or radeon, amdgpu. (For AMD blacklist radeon, amdgpu, etc.)Ĥ. When done, run sudo update-grub before rebooting. When done, run sudo update-grub before rebooting.Įdit /etc/default/grub and add modprobe.blacklist=nouveau to GRUB_CMDLINE_LINUX_DEFAULT.
In fact, you may want to swap steps 3 and 4.Ĭreate file /etc/X11//nf (this may require mkdir /etc/X11/), containing: Section "OutputClass"Įdit /etc/default/grub and add xdg.force_integrated=1 to GRUB_CMDLINE_LINUX_DEFAULT. Don't needlessly blacklist the kernel modules, as this could mean the discrete card won't be powered down. The following steps should achieve the first goal to increasing degrees of thoroughness.Ĭheck for improvement after each step, and stop when it works. If I understand correctly, your first wish is to run on the IGD exclusively, then sort the remaining issues.
