Description Simona Pisano 2025-02-18 13:40:50 UTC

starting from plasma 6.3 when i boot in energy saving mode the display brightness change function is completely missing.
if i run "systemctl --user status plasma-powerdevil" i find the error "feb 17 17:22:20 simonapc1 org_kde_powerdevil[4224]: busno=9, sleep-multiplier = 2,00. Testing for supported feature 0x10 returned Error_Info[DDCRC_RETRIES in ddc_write_read_with_retry, causes: DDCRC_NULL_RESPONSE(10)]"
when i do "systemctl --user restart plasma-powerdevil " all goes ok
