I got these errors at the time as I had not added my user to the i2c group. ``` 08:40:44 org_kde_powerdevil[1827]: [ 1968][900.449310] Open failed for /dev/i2c-5, errno=EACCES(-13): Permission denied in file i2c_bus_core.c near line 433 08:40:44 org_kde_powerdevil[1827]: [ 1968][900.449365] open() failed with 1 EACCES errors, total retry ms = 100 08:40:44 org_kde_powerdevil[1827]: [ 1968][900.450380] Open failed for /dev/i2c-6, errno=EACCES(-13): Permission denied in file i2c_bus_core.c near line 433 08:40:44 org_kde_powerdevil[1827]: [ 1968][900.450396] Traced function stack 0x7fa26c0008b0 for current thread [ 1968] 08:40:44 org_kde_powerdevil[1827]: [ 1968][900.450405] dw_watch_display_connections 08:40:44 org_kde_powerdevil[1827]: [ 1968][900.450413] invoke_process_screen_change_event 08:40:44 org_kde_powerdevil[1827]: [ 1968][900.450418] process_screen_change_event 08:40:44 org_kde_powerdevil[1827]: [ 1968][900.450423] i2c_edid_exists 08:40:44 org_kde_powerdevil[1827]: [ 1968][900.450427] i2c_open_bus 08:40:44 org_kde_powerdevil[1827]: [ 1968][900.450431] i2c_open_bus_basic 08:40:44 org_kde_powerdevil[1827]: [ 1968] Open failed for /dev/i2c-6, errno=EACCES(-13): Permission denied in file i2c_bus_core.c near line 433 08:40:44 org_kde_powerdevil[1827]: [ 1968] Elapsed time since start of program execution: 900.450436 seconds 08:40:44 org_kde_powerdevil[1827]: [ 1968] Time since last resume from sleep: 900.313 seconds = 900314 millisec (900313657355nanosec) 08:40:44 org_kde_powerdevil[1827]: [ 1968] recently_returned_from_sleep() returned false 08:40:44 org_kde_powerdevil[1827]: [ 1968] uid: 1003=user2, euid: 1003=user2, gid: 1003=user2, egid: 1003=user2 08:40:44 org_kde_powerdevil[1827]: [ 1968] Checking for group i2c... 08:40:44 org_kde_powerdevil[1827]: [ 1968] Group i2c exists 08:40:44 org_kde_powerdevil[1827]: [ 1968] WARNING: Current user user2 is NOT a member of group i2c 08:40:44 org_kde_powerdevil[1827]: [ 1968] Permissions for /dev/i2c-6: 08:40:44 org_kde_powerdevil[1827]: [ 1968] file owner: 0=root, file group: 969=i2c 08:40:44 org_kde_powerdevil[1827]: [ 1968] access(/dev/i2c-6) failed, errno=13 08:40:44 org_kde_powerdevil[1827]: [ 1968] faccessat(0,/dev/i2c-6,R_OK|W_OK, AT_EADCESS) failed, errno=13 08:40:44 org_kde_powerdevil[1827]: [ 1968] Using command getfacl: 08:40:44 org_kde_powerdevil[1827]: [ 1968] getfacl: Removing leading '/' from absolute path names 08:40:44 org_kde_powerdevil[1827]: [ 1968] #
