Please don't > close it until the problem is fixed in the mainline. I recently bought an Acer Travelmate 4530 AMD Athlon 64 dual-core with ATI Radeon HD3200 graphics on which I installed Debian/Sid. When using kernels 2.6.30 and 31 the backlight control doesn't work well. Only occasionly there is /sys/class/backlight and /sys/devices/virtual/backlight/acpi_video, most times these dirs are empty. Sometimes it boots with backlight very low, sometimes maximum. When the mentioned dirs are empty there is no control of the backlight, otherwise the control is buggy, too dark or to light. When using linux-image-2.6.29 there's no problem with the backlight. -- Configure bugmail: http://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug. ------------------------------------------------------------------------------ Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.
