Problem with libGL on Debian8.0

[victor wang]

Hi, i'm using Qt5.5 on my computer.
And i got some problem here.
It seems great when i compile my program but when i execute my program it will show the warning like below.

libEGL warning: DRI3: Screen seems not DRI3 capable
libEGL warning: DRI2: failed to authenticate

I assume that it is the reason why i set full screen mode in my program but it is not going like that when i execute my program.

How can i solve this problem?
Please help.

Hi,

What graphic card do you have installed ? Which driver are you currently using for it ?
