Yes. Killing X restores the console, but restarting X from any location still gives me a black screen. Even when using the DVI port, I can ctrl-alt-F1 back to the console, I just have to be patient while the LCD monitor figures out the change in scan rates. > I just hit this problem this morning on another computer, this time > with an RV380.

Are there any radeon driver patches, or even known troublesome locations I could start poking at? Compiler warnings I see when building xf86-video-ati-6.13.0 on this amd64 machine are radeon_accel.c: In function ‘RADEONHostDataBlit’: radeon_accel.c:855: warning: ‘__expected’ may be used uninitialized in this function radeon_atombios.c: In function ‘rhdAtomParseI2CRecord’: radeon_atombios.c:1596: warning: initialization from incompatible pointer type and a gazillion of the harmless atombios_crtc.c: In function ‘atombios_crtc_mode_set’: atombios_crtc.c:580: warning: dereferencing pointer ‘adp3_ptr’ does break strict-aliasing rules - Larry _______________________________________________ [email protected]: X.Org support Archives: http://lists.freedesktop.org/archives/xorg Info: http://lists.freedesktop.org/mailman/listinfo/xorg Your subscription address: [email protected]
