Display running in low graphics mode after update

[santam chakraborty]

After update and restart the computer fails to boot as it shows that it is running in the low graphics mode. Trying to troubleshoot with the use of backup configuration / default configuration fails. I had to downgrade kernel to access to the computer.

This happens to me as well. Able to access my computer from 3.19.0-25. Attempting to boot in kernel 3.19.0-26 causes low graphics mode followed by a freeze on "starting version 219".
