You have been subscribed to a public bug: I have experienced this for ubuntu 18.04 and 18.10 on a Lenovo Miix 510 laptop. This problem is fixed on ubuntu 19.04
The login page appears sideways (the mouse orientation is sideways also). After logging in the screen is corrected. I believe the issue lies with the detection of the accelerometer or perhaps the driver of the accelerometer. ** Affects: ubuntu Importance: Undecided Status: New ** Affects: linux (Ubuntu) Importance: Undecided Status: New ** Tags: bionic bot-comment cosmic -- login page first appears sideways for Lenovo miix 510 ubuntu 18.04 and 18.10 https://bugs.launchpad.net/bugs/1832436 You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
