Subject: [PATCH 0/2] Pixel 3 display fixes
Date: Sun, 09 Aug 2026 02:04:28 +0200 [thread overview]
Message-ID: <20260809-fix-blueline-panel-v1-0-e7f3a6beb1fa@ixit.cz> (raw)
Fix panel not recovering after unprepare and backlight intensity.
I extensively reproduced the vendor bootloader sequence, but after the
boot isn't possible to do the full initialization of the display (at
least on Pixel 3, and panel can't be found anywhere else).
The downstream, due to having attached touchscreen reusing same
supplies, never turns the panel off. Let's do the same.
