This is the output for kernel 4.6.4-040604-generic (running back on Ubuntu 16.04, but I guess that shouldn't make any difference if we're just reading the kernel info):
/sys/class/drm/card0-eDP-1/modes:3840x2160 (There's a bunch of other modes but they are all for the various resolutions on the HDMI screen). So it looks like it's just seeing one mode for the laptop screen, the native resolution. Does that mean it's inventing a bunch of modes anyway - just not the right ones? -- 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/1606103 Title: modeset driver does not detect all screen resolutions To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1606103/+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
