Hi, I've started encountering a weird problem: roughly one in three times, something will crash when I try to log in, and bounce me back to the login manager (slim in my case). When I look in .xsession-errors, I can see: XIO: fatal IO error 4 (Interrupted system call) on X server ":0.0" after 8690 requests (8690 known processed) with 0 events remaining. XIO: fatal IO error 11 (Resource temporarily unavailable) on X server ":0.0" after 2823 requests (6 known processed) with 0 events remaining. lxpolkit: Fatal IO error 11 (Resource temporarily unavailable) on X server :0.0. X connection to :0.0 broken (explicit kill or server shutdown). X connection to :0.0 broken (explicit kill or server shutdown). X connection to :0.0 broken (explicit kill or server shutdown). But I'm not sure what this means or how to debug further. Here's the full .xsession-errors https://pastebin.com/t3AcV7dC Any help would be appreciated. -- There are 10 types of people, those who know binary and those who don't.
