Thanks for the patch! I will take a look, but I need a licence grant that we can use it under the MIT licence in order to integrate it.

Ahem, I have taken a look and this is a patch against X.Org, not VirtualBox. Was that intentional?
comment:3 Changed 16 months ago by gandi_gk
yes I know but getting an answer from xorg for integration is impossible and I tried at least let people know a solution. Various bugs are pointing to the same issue so I wanted to help people only to get rid off it. People can use it in any way the want. But if this bug entry and solution is not ok so: feel free to delete it ;-)

The way it is done in the "modesetting" driver<1> should solve the problem, but it will have to wait for (quite) a bit until I get round to it.
