Comment 5 for bug 1618423

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?
