we have T4-2 as sunray server with sun ray version 4.5_44 installed.
30 sun ray 3 plus DTUs are connected to the server over network. among the 30 clients , 13 client's display resolution were suddenly changed to 640x480@60Hz. remaining around 17 clients have the required resolution of 1920x1200@60Hz.
with the 17 properly working clients, for root login, the display appears to be correct but for some newly created users, the displays are bigger.
please advise what could be the issue.
