[Qemu-discuss] libdrm framebuffer applications not updating

[Fernando Rodriguez]

Hello,

I'm working on a framebuffer application (currently using a DirectFB 
driver) and I'm writing a libdrm driver for it. When using the DRM 
driver the display window does not get updated until I use CTRL-TAB to 
switch the active window. That is with the GTK+ qemu backend and the qxl 
driver. With the SDL backend the window does not update at all, even
when switching. When using DirectFB (fbdev backend) everything works as 
it should with the GTK+ interface and QXL driver.

The problem can be reproduced with the libdrm examples found here:
https://github.com/dvdhrm/docs/blob/master/drm-howto/modeset.c

I'm using a Gentoo box with intel graphics.

Any suggestions?

Thanks in advance,
