After you upgrading Ubuntu I get black screen and only the cursor is visible. I get an error like this:
"Could not apply the store configuration for monitors
None of the selected modes were compatible with the possible modes:
Trying modes for CRTC 82
CRTC 82: trying mode 1280x720@0Hz with output at 1600x900@50Hz (pass 0)
CRTC 82: trying mode 1024x720@61Hz with output at 1600x900@50Hz (pass 0)
and many more of those CRTC 82:, it is kind of difficult to type them all on a phone.
I wish I could post the log file but I don't know how to do it through the command line. Any suggestions would be highly appreciated? Thanks in advance.
