Talked to Bin and he no longer has this issue, so I'm closing this bug. ** Changed in: linux (Ubuntu) Status: Confirmed => Fix Released -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1798708 Title: It will load nvidia driver when swith to Intel mode To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1798708/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1798708] Re: It will load nvidia driver when swith to Intel mode
The external monitor problem is probably a well-known gdm3 bug: gdm3 with nvidia modeset=1 stops the nvidia driver from detecting external monitors (possibly it invokes some wayland features when it shouldn't). It is not a problem with nvidia-prime or with the kernel. You can fix it by using lightdm instead of gdm3. This bug affects fedora as well. ubuntu 19.04 has reverted to nvidia modeset = 0 be default to avoid this bug (at the cost of unfixable screen tearing for Optimus users in nvidia mode). nvidia-prime does always include the nvidia modules in the initramfs kernel, this was a change in 18.10 backported to 18.04. Previous nvidia- prime pacakges used to rebuild initramfs to add or remove the module, but this is not required any longer. Choosing prime-select intel means the nvidia module is unloaded when the machine is starting. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1798708 Title: It will load nvidia driver when swith to Intel mode To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1798708/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1798708] Re: It will load nvidia driver when swith to Intel mode
Here is another workaround. When in Nvidia mode, do below commands. First add/edit nvidia-kms.conf, comment out "options nvidia-drm modeset=1", it will fix the external monitor issue. $ prime-select intel # It will generate /lib/moprobe.d/blacklist-nvidia.conf $ update-initramfs -u These will fix the nvidia or noveau loaded in intel mode. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1798708 Title: It will load nvidia driver when swith to Intel mode To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1798708/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

After I removed the nvidia-kms.conf or change option "nvidia-drm modeset=0", then update initramfs, the external monitor will work fine. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1798708 Title: It will load nvidia driver when swith to Intel mode To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1798708/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

After the workaround in comment 2, I found the external monitor couldn't be used ThinkPad P1 and P72, it's a critical issue. For normal user, they just switch from intel to nvidia, after that update-initramfs, the external monitor can't work. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1798708 Title: It will load nvidia driver when swith to Intel mode To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1798708/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

apport information ** Tags added: apport-collected bionic ** Description changed: We found the nvidia-prime will not run update-initramfs as before. After switch to intel, then reboot I found the nvidia modules was loaded. If I did S3 or close the lid, and resume back, the nvidia modules was removed, so the gnome session will be reloaded, you need to login again, all the opend applications in this session was gone. nvidia-prime 0.8.8.1 linux 4.15.0-1021-oem nvidia-driver-390 380.87-0ubuntu0~gpu18.04.1. + --- + ProblemType: Bug + ApportVersion: 2.20.9-0ubuntu7.4 + Architecture: amd64 + AudioDevicesInUse: + USERPID ACCESS COMMAND + /dev/snd/controlC1: u 2218 F pulseaudio + /dev/snd/controlC0: u 2218 F pulseaudio + CurrentDesktop: ubuntu:GNOME + DistributionChannelDescriptor: + # This is the distribution channel descriptor for the OEM CDs + # For more information see http://wiki.ubuntu.com/DistributionChannelDescriptor + canonical-oem-sutton-bionic-amd64-20181018-40+sutton-mccarthy-bionic-amd64+iso + DistroRelease: Ubuntu 18.04 + HibernationDevice: RESUME=UUID=2b45d917-3587-410f-9b94-f52eb082b7dc + InstallationDate: Installed on 2018-10-19 (0 days ago) + InstallationMedia: Ubuntu 18.04 "Bionic" - Build amd64 LIVE Binary 20181018-09:17 + MachineType: LENOVO 20MEZ480US + NonfreeKernelModules: nvidia + Package: linux (not installed) + ProcFB: 0 inteldrmfb + ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-4.15.0-1021-oem root=UUID=e68fa8d5-22f5-464b-9775-753b4ae159eb ro noprompt quiet splash acpi_osi=! acpi_osi=Linux-Lenovo-NV-HDMI-Audio vt.handoff=1 + ProcVersionSignature: Ubuntu 4.15.0-1021.24-oem 4.15.18 + RelatedPackageVersions: + linux-restricted-modules-4.15.0-1021-oem N/A + linux-backports-modules-4.15.0-1021-oem N/A + linux-firmware 1.173.1 + Tags: bionic + Uname: Linux 4.15.0-1021-oem x86_64 + UpgradeStatus: No upgrade log present (probably fresh install) + UserGroups: adm cdrom dip lpadmin plugdev sambashare sudo + _MarkForUpload: True + dmi.bios.date: 10/04/2018 + dmi.bios.vendor: LENOVO + dmi.bios.version: N2EET30W (1.12 ) + dmi.board.asset.tag: Not Available + dmi.board.name: 20MEZ480US + dmi.board.vendor: LENOVO + dmi.board.version: SDK0Q40104 WIN + dmi.chassis.asset.tag: No Asset Information + dmi.chassis.type: 10 + dmi.chassis.vendor: LENOVO + dmi.chassis.version: None + dmi.modalias: dmi:bvnLENOVO:bvrN2EET30W(1.12):bd10/04/2018:svnLENOVO:pn20MEZ480US:pvrThinkPadP1:rvnLENOVO:rn20MEZ480US:rvrSDK0Q40104WIN:cvnLENOVO:ct10:cvrNone: + dmi.product.family: ThinkPad P1 + dmi.product.name: 20MEZ480US + dmi.product.version: ThinkPad P1 + dmi.sys.vendor: LENOVO ** Attachment added: "AlsaInfo.txt" https://bugs.launchpad.net/bugs/1798708/+attachment/5202761/+files/AlsaInfo.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1798708 Title: It will load nvidia driver when swith to Intel mode To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1798708/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
