Summary: [egl] When program ends, monitor is switched off leaving system unusable Product: Mesa Version: git Platform: x86-64 (AMD64) OS/Version: Linux (All) Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/r600 AssignedTo: dri-devel@lists.freedesktop.org ReportedBy: rleigh@debian.org
Using current git and mesa demos 8.0.1 for testing, with linux 2.6.39 with radeondrmfb on a radeon HD4850/RV770 graphics card, and HP LP2475w monitor via an HDMI cable. I'm using EGL_PLATFORM=drm running on the framebuffer console.
What I see is that the demo programs run at the native resolution (1920×1200) but when the program ends (either by C-c/SIGTERM or by ending after the 5 seconds it runs for) it causes the display to power down, leaving the system in an unusable state. [I'm running X on vt7, so a switch to vt7 and back makes things work again, but if I wasn't running X, I'd need to reboot the system to reinitialise things.]
I've tested with src/egl/opengles1/gears_screen, src/egl/opengles1/torus_screen and src/egl/openvg/lion_screen (the rest of the demos have glx dependencies or other deps which make them fail to run on the console).
A log of a sample run is attached. Note the kernel HDMI hot plug events from the kernel log at the end which are presumably related. I'm not sure when these are issued due to the monitor being off. It might be at power down, or when I switch to vt7 and back again.
Regards, Roger
