No brightness control window 74/16/2024 So it seemed like that kernel or install had issues (at least for me). ![]() The only kernel installed on my machine up until today was 4.0.5-1. When I last installed Tumbleweed I used a snapshot from mid June. After updating to kernel 4.1.1-1 things seem to work with no additional adjustments from me. Thanks for any assistance you can provide. Also running lsmod|grep acpi returns nothing.Ħ.500070] ACPI: Video Device (multi-head: yes rom: no post: no)įor i in /sys/class/backlight/* do echo $i cat $i/brightness cat $i/actual_brightness cat $i/max_brightness done I’ve tried updating kernel parameters to include “acpi_backlight=vendor acpi_osi=Linux” but have had no luck.

I’ve been researching this for about 1 month now. I hope one of the experts here can point me in the right direction to get this resolved. The only time it worked on TW was when I did a zypper dup upgrade and booted into an old 3.x kernel from 13.1. On my laptop all 4.x.x kernels seem to be affected. On TW, when I press the backlight fn keys I see the monitor indicator showing it’s receiving input from my keystrokes but the screen’s brighness does not change until I reduce the slider all the way down at which point the monitor goes completely dark. My monitor is stuck on maximum brightness. However on Tumbleweed it does not as I can not change the monitor brightness (backlight). On 13.1 brightness control works flawlessly using fn keys. ![]() Memory Range: 0xc2440000-0xc245ffff (ro,non-prefetchable,disabled) Memory Range: 0xc2400000-0xc241ffff (rw,non-prefetchable) Memory Range: 0xb0000000-0xbfffffff (ro,non-prefetchable) SubVendor: pci 0x103c "Hewlett-Packard Company" Vendor: pci 0x1002 "ATI Technologies Inc"ĭevice: pci 0圆740 "Whistler XT " Whistler Ģ3: PCI 100.0: 0300 VGA compatible controller (VGA) My graphics card is an ATI:Ġ1:00.0 VGA compatible controller: Advanced Micro Devices, Inc.
