I won't report again with latest kernel because (from my experience) I do not expect it to be solved (or that it solved because of people reporting bugs), but I still provide the following information to save the time for those who wish to find a workaround - I do not know a workaround, but I know the following would not work:
The following methods would not prevent the desktop to rotate automatically after login: - delete /lib/udev/accelerometer - comment out the only line in /lib/udev/rules.d/61-accelerometer.rules Since the rotate-after-login does not alter input matrix, which is still horizental, touch-screen will be useless right after login, until you rotate the screen back (with xrandr -o randr). If, instead of preventing auto-rotate-after-login, you wish to rotate input matrix as well to make the machine at least usable, the following command would not work: $ xinput set-prop 9 --type=float "Coordinate Transformation Matrix" 0 -1 1 1 0 0 0 0 1 The effect of that command is zero: input matrix remain the same (horizental) while the screen is auto-rotated to vertical. If you wish to study the issue, a starting point is the accelerometer device, which can be found in /proc/bus/input/devices Find out the event device (in my case event4) then you can find out which driver drives it by: $ cat /sys/devices/platform/asus_laptop/input/input4/device/driver -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1326885 Title: desktop start rotated To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1326885/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
