My issue is very similar to Black screen after unlock screen os 6
Just locking the screen and unlocking it is not returning to the desktop. Here is what I got:
And checking the dmesg
following line caught my attention:
traps: pool-io.element[34441] trap int3 ip:9fac32u543878 error:0 in ibglig-2.0.so.0.6400.6
How can I fix this issue and get the desktop after unlocking?
