Package: tlp Version: 1.7.0-1 Severity: important Tags: upstream X-Debbugs-Cc: r...@debian.org
The default setting for AMD_ABM_LEVEL_ON_BAT (1) renders my laptop
unusable after resuming from suspend on battery. In particular, it
adjusts my screen brightness in an increasingly fast loop, where the
screen fades from zero to full brightenss over the span of a second and
a half, then restarts the fade from zero to full over 0.75 seconds, over
0.5 seconds, over 0.25 seconds, causing a flickering sensation, until
the screen is just stuck off. Suspending (by shutting the laptop lid)
and resuming restarts the loop. I've managed to narrow down the bug to
the value of AMD_ABM_LEVEL_ON_BAT: setting it to 0 disables the
behaviour; setting it to 1 re-enables it. My graphics card is:
