** Description changed: When I login, I type the password on the laptop screen. (Maybe it's important.) After a while, while I'm waiting to get logged in, Ubuntu changes the display mode. Both monitor goes black, laptop screen becomes the secondary and my external monitor becomes the primary display. Because of Ubuntu is unable to remember to the previously set display mode, I usually change it a bit after I have logged in. However, if I (would like to) do this too quickly, say... less than 4-5 seconds after I can see my desktop, my session gets terminated and I'm returned to the - login screen. You can repeat it indefinitely, it always worked (?) for - me. + login screen. You can repeat it indefinitely, it always worked for me. I thought it's because of one of my extensions but I could reproduce it after I have disabled them. I haven't found any useful log entries. + + + UPDATE 1: + While I was writing this, I thought it has something to do with theme loading or something like this, so I continued to test with startup applications. + I just rarely managed to reproduce this bug when I didn't execute the following script (as a file) at login: + ``` + #!/bin/bash + sleep 1s; firefox & + sleep 1s; thunderbird & + ``` + + I also noticed that after I have some faulty logins and then I login + without changing display mode, I >sometimes< have no desktop, no startup + applications and when I click power off/logout buttons nothing happens, + but that's sure I will being logged out randomly in the near future - + even if I don't touch my computer (I'm talking about minutes). + + Plus, I can see the desktop and the top bar (so it's the primary screen) + with two wide black bars on the two sides of my laptop monitor for a + moment before I get logged out.
