Subject: [PATCH] monitor-manager: Fix the max potential number of logical
|
|
|
2c033f |
monitors
|
|
|
2c033f |
|
|
|
2c033f |
The max potential number of logical monitors (i.e. MetaMonitorInfos)
|
|
|
2c033f |
is the number of CRTCs, not the number of outputs.
|
|
|
2c033f |
|
|
|
2c033f |
In cases where we have more enabled CRTCs than connected outputs we
|
|
|
2c033f |
would end up appending more MetaMonitorInfos to the GArray than the
|
|
|
2c033f |
size it was initialized with which means the array would get
|
|
|
2c033f |
re-allocated rendering invalid some MetaCRTC->logical_monitor pointers
|
|
|
2c033f |
assigned previously and thus ending in crashes later on.
