Thanks for following up. I read most of that document, but it's difficult in places. My understanding is that what you're asking me to do is what's described under “Commit bisecting Ubuntu kernel versions,” correct? That's the only part of the main page (excluding the FAQ below) that seems to apply.
But I don't see anything on the page addressing the question of “what if you want to bisect revisions that are not tagged in the branch.” Are you saying you don't want me to bisect Ubuntu kernels in that case, and go to the upstream kernels instead? -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1300557 Title: Screen resolution no longer works Status in linux package in Ubuntu: Incomplete Bug description: My display's native resolution is 2560×1440 pixels. Prior to, I think, Saucy I could only reach this resolution by adding it using xrandr, and then calling xrandr on boot/login to select that resolution. The Display preferences did not show any higher options than 1920×1200. In Saucy, the native resolution just worked, and I could stop using xrandr. It also worked in Trusty in the alpha releases, up to (and I think including) beta-1. But today (this is not an April's fool, is it?) I rebooted after an upgrade, and found myself back in 1920×1200. Again, the Display preferences list that resolution as the highest possible. But this time, attempts to ‘xrandr --addmode’ my native resolution failed. The error message wasn't very helpful; I'll try to reproduce it later but it throws my display into yet a lower resolution that's hard to work with.
