[Bug 1394653] Re: gpu-manager's xorg.conf generation should be configurable
I've been struggling with this for the past year, but never thought to file a bug report. My use case is a little different, but the base request - allow customization of the Xorg config - is the same. My system is an Intel Skull Canyon NUC with Iris Pro integrated graphics. I also have an external GPU box with an Nvidia 1080 Ti that connects to the system with a Thunderbolt interface. Two displays are connected - one to the main system's port, and one to external video card's port. The Nvidia driver requires an option added to the Xorg config to use the external GPU: Option "AllowExternalGpus" "True" If this is not set, the Nvidia section of the Xorg config will fail, and this cascades to Xorg not starting (i.e. login screen immediately drops back to login screen.) Currently I work around this by editing /usr/share/X11/xorg.conf.d/11-nvidia-prime.conf, which is generated by gpu-manager. The problem comes when a system update occurs, and gpu- manager is run again, re-generating the config file. Thus, it would be beneficial to have a way to save customizations of gpu-manager's configs. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1394653 Title: gpu-manager's xorg.conf generation should be configurable To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-drivers-common/+bug/1394653/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1394653] Re: gpu-manager's xorg.conf generation should be configurable
I've figured out (by looking through the xorg.0.log) that there's a config directory: /usr/share/X11/xorg.conf.d/ where I can put config snippets, so this bug report in the present form is invalid, as there is a way to configure X besides the autogenerated xorg.conf. I've created a file in the xorg.conf.d directory: 90-force-crt to force a virtual display to be recognized by the nvidia card, so i can align my laptop's internal screen to cover this virtual crt, thus being able to the internal screen. 90-force-crt content: Section "Screen" Identifier "nvidia" Device "nvidia" Option "AllowEmptyInitialConfiguration" "on" Option "IgnoreDisplayDevices" "" EndSection ** Attachment added: "generated xorg.conf" https://bugs.launchpad.net/ubuntu/+source/ubuntu-drivers-common/+bug/1394653/+attachment/4272021/+files/xorg.conf -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1394653 Title: gpu-manager's xorg.conf generation should be configurable To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-drivers-common/+bug/1394653/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I must mention that to make things work, I've written a bash script to add and set 1600x900 mode to the virtual crt screen at login, so it matches the resolution of my laptop's screen. The script is the following: (VGA-0 is the non-existent display recognized by the nvidia driver) #!/bin/bash if prime-select query | grep -q "nvidia"; then if xrandr | grep -q "HDMI-0 connected"; then xrandr --newmode "1600x900_60.00" 118.25 1600 1696 1856 2112 900 903 908 934 -hsync +vsync xrandr --addmode VGA-0 "1600x900" xrandr --output VGA-0 --mode "1600x900" fi fi ** Attachment added: "xorg.0.log with the above config" https://bugs.launchpad.net/ubuntu/+source/ubuntu-drivers-common/+bug/1394653/+attachment/4272028/+files/Xorg.0.log -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1394653 Title: gpu-manager's xorg.conf generation should be configurable To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-drivers-common/+bug/1394653/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Can you please attach a xorg.conf that works for you (and a /var/log/Xorg.0.log), so that I can see what's going on? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1394653 Title: gpu-manager's xorg.conf generation should be configurable To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-drivers-common/+bug/1394653/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
