[Plasma Mobile] Display goes dark after boot on Nexus 5 (lg-hammerhead)

    • Closed Imported Issue created by Administrator @root

    Posted by /u/magicvodi in /r/postmarketOS and confirmed by two more users in the thread:

    I installed following the steps in the wiki in a clean environment.

    PostmarketOS boots, i see the splash screen, MOTD, plasma-mobile loads (with really tiny font), and splitseconds after the top and bottom bar appear the display turns off.

    The phone doesn't react to any key presses or touching the screen.

    I can connect via ssh without problems.

      Display doesn't go completely off, but brightness is turned down. Which is known bug to me upstream.

      Is there an easy way to turn the brightness on again?

      Relevant part,

      Jan  1 01:59:59 lg-hammerhead user.notice bernhard:plasma-mobile: powerdevil: Screen brightness value max:  255
Jan  1 01:59:59 lg-hammerhead user.notice bernhard:plasma-mobile: powerdevil: Screen brightness value:  180
Jan  1 01:59:59 lg-hammerhead user.notice bernhard:plasma-mobile: powerdevil: Screen brightness value max:  255
Jan  1 01:59:59 lg-hammerhead user.notice bernhard:plasma-mobile: powerdevil: set screen brightness value:  1
Jan  1 01:59:59 lg-hammerhead daemon.notice dbus[1380]: [system] Activating service name='org.kde.powerdevil.backlighthelper' (using servicehelper)

      I think what you can do is write 180 value to /sys/devices/platform/soc/f9967000.i2c/i2c-3/3-0038/backlight/lm3630a_leda/brightness as workaround.

      echo 180 | sudo tee /sys/devices/platform/soc/f9967000.i2c/i2c-3/3-0038/backlight/lm3630a_leda/brightness manages to get the display on but the UI is so small it is unusable.

      FYI: !151 (merged) might fix the small fonts issue (at least it is fixing another issue). It will get merged next week, I'll need to pre-build the packages for all architectures first.

      If somebody is fine with compiling a lot of packages locally, you could try to checkout that MR and do a pmbootstrap install and see if it fixes the issue.

      Setting the brightness in settings to 100% also only sets /sys/devices/platform /soc/f9967000.i2c/i2c-3/3-0038/backlight/lm3630a_leda/brig htness to 50, rather than 255.

      I would like to write 180 value to /sys/devices/platform/soc/f9967000.i2c/i2c-3/3-0038/backlight/lm3630a_leda/brightness but I can't ssh into the phone. Would it be possible to set this value into the pmOS image before flashing this image to the phone?

      Well, maybe, but not having SSH sounds like a bigger issue tbh. I don't think we want device specific workarounds in UI packages.

      Anyways, since the bug is known upstream, this should be fixed soon.
