So, it seems to me that following your example, if I wanted to |
70 |
experiment with screen backlighting what would I do? I'm in KDE BTW in |
71 |
case we're doing something different in that regard. |
72 |
|
73 |
I see in the Global Keyboard Shortcuts in KDE that there are |
74 |
Monitor Brightness Down/Up controls defined but I'm not understanding |
75 |
what keys actually control those. I Googled around for a minute and |
76 |
found Fn-ArrowUp/ArrowDn but they didn't work o I'm hoping you can |
77 |
tell me and save me a few minutes. Maybe it's because I haven't |
78 |
started something required? |
79 |
|
80 |
acpi_listen on n-ArrowUp/Dn does produce a response so maybe I |
81 |
don't have something properly mapped? |
82 |
|
83 |
I do have baselayout1.start/stop stuff so it seems our systems are |
84 |
fairly different. |
85 |

Thank in advance, |
