http://bugs.freedesktop.org/show_bug.cgi?id=24617 Summary: Wrong backlight level detection using AtomBIOS Product: xorg Version: unspecified Platform: Other OS/Version: All Status: NEW Severity: normal Priority: medium Component: Driver/radeonhd AssignedTo: lverhaegen@suse.de ReportedBy: zajec5@gmail.com QAContact: xorg-team@lists.x.org It's bug in AtomBIOS or our reading AtomBIOS answer. My backlight is controlled by GPU so there are two important properties to check: 1) Is backlight control turned on 2) What level is used After booting backlight control is turned *off* and backlight value set to 0. Of course backlight level doesn't matter in that case, as backlight control is disabled. Backlight level is max in result. AtomBIOS ignores fact that backlight control is turned off, just reports backlight level (or not AtomBIOS, but out AtomBIOS parser hopefully). So after booting I have max backlight level and this: PANEL connected 1600x900+0+0 (normal left inverted right x axis y axis) 423mm x 238mm Backlight: 0 (0x00000000) range: (0,255) _PanningArea: _OutputNumber: 2 (0x00000002) ConnectorNumber: 2 (0x00000002) ConnectorType: Panel SignalFormat: LVDS supported: LVDS -- Configure bugmail: http://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the QA contact for the bug. _______________________________________________ xorg-team mailing list xorg-team@lists.x.org http://lists.x.org/mailman/listinfo/xorg-team -- To unsubscribe, e-mail: radeonhd+unsubscribe@opensuse.org For additional commands, e-mail: radeonhd+help@opensuse.org
