The output of those commands are: 1.2.13 and 08/08/2016. I can't test the same configuration that I originally tested for another week, but on another 1680x1050 monitor it did work, eventually. I had to restart lightdm several times because things happened like the mouse click no longer working, once when I changed the resolution it flipped everything sideways, and the mouse started moving extraordinarily slowly and the desktop was unusable.
My issue is that there's a more severe bug with the brightness control after resume in the newer BIOS and its predecessor, so I can't use it (see http://en.community.dell.com/techcenter/os- applications/f/4613/p/19985875/20927410#20927410). Dell's official response is that they are aware of it, but they clearly aren't fixing it since they have released a second BIOS with the same bug. If it's purely a BIOS issue, why does the modeset driver have this screen resolution problem and not the intel driver? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1618423 Title: Modesetting driver cannot handle different display resolutions for two monitors To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1618423/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
