--- Comment #17 from Patrick <ps_mail at freenet.de> --- (In reply to comment #14) This could be true. I can control it via /sys/class/backlight/acpi_video0/brightness. If I change /sys/class/backlight/radeon_bl0/brightness then the display is nearly black and cannot be restored. After reboot the following values are set: acpi_video0 = 7 radeon_bl0 = 0 I've attached a lspci -vvv to " lspci output for amilo" and the vbios to "vbios from Amilo" -- You are receiving this mail because: You are the assignee for the bug. -------------- next part -------------- An HTML attachment was scrubbed...
