So, this is my setup :
xUbuntu 18.04
Nvidia 390.48 on Nvidia TI750 card
Dual Monitor (one on DispayPort, Second is DVI)
Multiuser setup.
My problem is - when i boot - everything is fine and work as expected - desctop is extended on both monitors. When i log in as first user - its still OK.
BUT, once i try to change user shit happens. GDM screen first drops on VGA resolution (640x480). Second user logged in have both screen mirrored (not extended) and both in VGA mode. Nvidia setting started by second user shows basically nothing. No info about drive, about card anything.
If i simply chnge to firt user - everthing go back fine! Again. if i log out both users and relogin second (it will work on full res).
To cut it short - only one session works normally.
I have tried newer, Nvidia 396 driver from official PPA - no good either. Basically same problem and frequent xorg crashes.
On 17.04 and Nvidia 384 i have no such problem.
I have searched internet and found that some peoples have similar problem, its related to dual monitor setup it seems.
Its also seems that one of 390 drivers had such problem according to Nvidia release notes, but it should be already fixed on version provided in Ubuntu.
Thats problem is blocker for 18.04 to me.
