I think I have found the culprit: till@till-twist:~/kernel/linux-stable$ git bisect good Bisecting: 4 revisions left to test after this (roughly 2 steps) [740922ee575f8ee4daa2bfd3db5f69dd7573fc76] drm: don't add inferred modes for monitors that don't support them till@till-twist:~/kernel/linux-stable$
The extra modes in reality work with the monitor, and they give extra chances to find a best match between laptop screen and external monitor/projector. Anyway, I will continue the bisect to confirm ... -- 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/1167301 Title: 8086:0166 [ThinkPad Twist S230u 3347] REGRESSION: Mirroring display works only with 1024x768 (4:3) whereas my laptop has 1366x768 (16:9) & external monitor 1920x1080 (16:9) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1167301/+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
