Just had the idea to unload "glx" and see if I can Disable Composite without crashing Xorg / startx / xinit.
It works! Here's my xorg.conf: Section "Module" Disable "glx" EndSection Section "Extensions" Option "Composite" "0" EndSection I'll put my resulting Xorg.0.log as an attachment. However logically this prevents me from getting DRI (which I need), while glxinfo saying: "LIBGL_DEBUG=verbose glxinfo name of display: :0 Error: couldn't find RGB GLX visual or fbconfig" Interesting though that Xorg no longer crashes with Composite being disabled when I disable the glx module at the same time. ** Summary changed: - [bionic] startx / xinit crashes with Composite Disabled in xorg.conf + [bionic] startx / xinit crashes with GLX backtrace if Composite Disabled in xorg.conf ** Attachment added: "Xorg.0.log.txt" https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1754296/+attachment/5075590/+files/Xorg.0.log.txt -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1754296 Title: [bionic] startx / xinit crashes with GLX backtrace if Composite Disabled in xorg.conf To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1754296/+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
