http://bugzilla.opensuse.org/show_bug.cgi?id=1209296 Bug ID: 1209296 Summary: Missing backlight control on Dell Vostro 3700 Classification: openSUSE Product: openSUSE Tumbleweed Version: Current Hardware: x86 OS: openSUSE Tumbleweed Status: NEW Severity: Normal Priority: P5 - None Component: Kernel Assignee: kernel-bugs@opensuse.org Reporter: eh@eggbird.eu QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- Created attachment 865548 --> http://bugzilla.opensuse.org/attachment.cgi?id=865548&action=edit output of dmesg on kernels before 6.2.1 and WITH the kernel parameter acpi_backlight=native /sys/class/backlight contained nv_backlight. Starting with 6.2.1 AND the same parameter /sys/class/backlight remains empty. After removing the kernel parameter the directory contains acpi_video0. The backlight parameter in /sys/class/backlight/acpi_video0 responds to the function keys to increase/decrease the backlight, but the "real" backlight does not respond. I've just (15 March) installed 6.2.4-1-default but the problem remains. -- You are receiving this mail because: You are the assignee for the bug.
