--- Comment #7 from svily0 at yahoo.com --- I connected a third panel today and it works, the two old ones do not! It's not the connector, just the panels were somehow rendered unusable. I don't really know how to investigate further as the panel is a complete unit, which is hard to open. There is no backlight and there is not even the faintest of image on the LCD. Another strange thing is that, when booting with radeon.dpm=1, even the HDMI output doesn't work after doing the mode setting and before KDE is started. Without this parameter I can see all kernel messages at boot time. -- You are receiving this mail because: You are watching the assignee of the bug.
