Hello everyone,

I am facing a very strange problem with X crashing when I am trying to perform a vt switch. I am running a custom application based on Qt5 which use opengl and some visual effects. My GPU is Intel HD2500, the X.org X server version is 1.14.3 and the intel driver module version is 2.21.15

When I try to switch from X to vt 1 the Xorg.0.log repeats the message

Code:
(II) AIGLX: Suspending AIGLX clients for VT switch


more than 10000 times and the X session crashes with no more messages.

The thing is that the problem occurs only when I use the intel driver with SNA accelaration enabled. If switch to UXA the problem disappears but a flickering on screen occurs.

Do you have any idea what might be wrong?

Thanks in advance.

Hello again,

I would like to add that i915 module is built-in into kernel and KMS is enabled. Also I noticed that

Code:
cat /sys/module/i915/parameters/modeset


returns -1.

Is this normal?

Thanks,
Mike

I manage to specifically reproduce the problem, please allow me to describe it in case someone can help.

Code:
X
export DISPLAY=:0.0
xterm


If I will kill xterm the X windows respawn. After that which ever graphics application I start it makes my tty consoles inaccesible and the cause X server to crash. In other words it seems that if the appication which claims tha X windows application stops, is not possible to claim it with any other.

You have face this problems before. Please help!

Thanks,
Mike
