[Ubuntu-x-swat] [Bug 1733136] Re: wayland session in Ubuntu 18.04 chooses LLVMpipe software driver on hybrid graphics system
The bug isn't in X server, but is related to EGL graphics drivers being installed incorrectly by ubiquity. ** Package changed: xorg-server (Ubuntu) => ubiquity (Ubuntu) ** Summary changed: - wayland session in Ubuntu 18.04 chooses LLVMpipe software driver on hybrid graphics system + libglvnd0/libegl installed in Ubuntu 18.04 breaks graphics drivers and forces LLVMpipe driver on i915 systems -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1733136 Title: libglvnd0/libegl installed in Ubuntu 18.04 breaks graphics drivers and forces LLVMpipe driver on i915 systems To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/1733136/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
[Ubuntu-x-swat] [Bug 1733136] Re: wayland session in Ubuntu 18.04 chooses LLVMpipe software driver on hybrid graphics system
FWIW, removing libglvnd0 fixed the problem (libegl1 does depend on it, but it isn't installed in artful either - libegl1-mesa is). So the bug is actually: a) the upgrade from artful to bionic installed libglvnd0 and libegl1 when they aren't needed; b) having libglvnd0/libegl1 installed breaks EGL on Intel-graphics systems. ** Description changed: + This bug is in ubiquity and in libglvnd0/libegl1: + + a) Upgrading from artful to bionic installs libglvnd0 and libegl1 when + they aren't needed; + + b) having libglvnd0/libegl1 installed breaks EGL on Intel-graphics + systems so you get llvmpipe as the video driver.

(Unity used to run when I first upgraded, but now gnome-shell is the only option because the gdm login screen offers no login options.) The upgrade did force me to remove bumblebee and nvidia, but afterwards I manually reinstalled bumblebee and nvidia-387 and reset to using intel via prime-select (installing nvidia changes some of the symlinks so that gnome-shell no longer boots, but "sudo prime-select intel" fixes this). The nvidia-387 modules are blacklisted in /etc/modprobe.d, and bumblebee isn't reporting any errors - bbswitch reports that the nvidia card is off, so I don't think it's an issue with hybrid graphics. (primusrun does work, as well.) Attached are the mutter logs that I generated via the environment variables mentioned in https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1724583 comment #20.

[Ubuntu-x-swat] [Bug 1733136] Re: wayland session in Ubuntu 18.04 chooses LLVMpipe software driver on hybrid graphics system
One difference between artful and bionic is that bionic has libglvnd0 installed (and libegl1 depends on it, so I can't really remove it). Artful doesn't have it installed. I read in one bug report (for Arch or Fedora? I can't find it now) with similar symptoms (ie no wayland session) that libglvnd was causing problems.

Yes definitely try blacklisting nouveau. The GTX 1050 is relatively new. In my experience the GTX 1060 (slightly older) only started working recently and the GTX 960 still doesn't work with nouveau at last check. Although when I say "working" I mean the machine boots without hanging and doesn't fall back to the LLVMpipe driver (which my GTX 1060 did for quite a while). -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1733136 Title: wayland session in Ubuntu 18.04 chooses LLVMpipe software driver on hybrid graphics system To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1733136/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp

[Ubuntu-x-swat] [Bug 1733136] Re: wayland session in Ubuntu 18.04 chooses LLVMpipe software driver on hybrid graphics system
And I only saw your feedback after I put my last comment in... :O The lspci -k command run from artful shows this: 01:00.0 3D controller: NVIDIA Corporation GP107M [GeForce GTX 1050 Mobile] (rev ff) Kernel modules: nvidiafb, nouveau, nvidia_387_drm, nvidia_387 I've got all those blacklisted though in /etc/modprobe.d/, and "lsmod|grep nvidia" and lsmod|grep nouveau" both return an empty string. (The configuration is pretty much the same in bionic as in artful.) I can't disable the discrete GPU in my BIOS, btw. bumblebee works fine in artful, though, turning off and hiding the nvidia card from gnome- shell, and primus runs an X session using the nvidia card quite happily from within gnome-shell, both under Wayland and X. I guess I should go back to bionic and blacklist nouveau as well as re- remove the nvidia driver and try again? Perhaps nouveau was being loaded when I tried last time. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1733136 Title: wayland session in Ubuntu 18.04 chooses LLVMpipe software driver on hybrid graphics system To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1733136/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp

P.P.S If you don't care for the Nvidia GPU and just want something that works reliably, you might be able to disable the discrete GPU properly in your BIOS. Just use integrated graphics. Then Linux will never see it at all and there shouldn't be as much confusion. ** Summary changed: - wayland session in Ubuntu 18.04 chooses vmware driver on intel hardware + wayland session in Ubuntu 18.04 chooses LLVMpipe software driver on hybrid graphics system -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1733136 Title: wayland session in Ubuntu 18.04 chooses LLVMpipe software driver on hybrid graphics system To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1733136/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
