After the laptop has been in sleep mode for a couple of hours,when I try and resume my session I get the following error:
Read-error on swap device
It takes about 30 seconds for the login screen to load post this happening. Once I log in, the screen blanks out once or twice for a second, and none of my programs are open anymore. I get a "System problem detected" prompt. When I click on "Send Report", another notification pops up saying:
Sorry the program "Xorg" closed unexpectedly. Your computeer does not have enough free memory to automatically analyze the problem and send a report to the developers.
What I have tried so far is to increase the swap space available. It was around 2 GB initially and I created another swap file of 9 GB. This hasn't helped. The occupied swap space ( as per the swapon command ) after the crash is always around 170MB.
The DMESG for when I resume my session, up to the read error on swap device is as follows:
