--- Comment #7 from Sandor Ecker (esanya@freemail.hu) --- I have upgraded to 5.6.rc1:
uname -a Linux Aspire-A315-41 5.6.0-050600rc1-generic #202002092032 SMP Mon Feb 10 01:36:50 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux
I have seen that the code has log messages like:
DC_LOG_BACKLIGHT("New Backlight level: %d (0x%X)\n", backlight_pwm_u16_16, backlight_pwm_u16_16);
I have set the kernel log by
echo "8" > /proc/sys/kernel/printk cat /proc/sys/kernel/printk 8 4 1 7
but I can't see any logmessage with "New Backlight" in the output of the commands:
grep -i "new backli" /var/log/* dmesg |grep -i "back"
Maybe it does not reach that line of code? Or the log should be visible somewhere else... ?
Can somebody help...?
