Gemini PDA - Linux / Lockscreen Freeze [Partial workaround found]
« on: September 19, 2018, 06:15:50 am »
From time to time, but overall quite regularly, I'm not able to unlock debian on my gemini anymore.
Usually when on debian, with wifi on, the screen gets locked due to inactivity or manually by a short Fn+Esc hit. Unlocking normally works by hitting Esc (worldmap appears), typing pwd and Enter. So far so good. But from time to time, there is no response on the Esc-wakeup keystroke. The screen just stays black, no worldmap screen showing up.
Trying to login blindly (?screen wakeup problem?) did not succeed. I tried the whole process from login to shutdown blindly by keyboard(*), but the system/device does not respond in any way. Also waiting does not help (checked 30min+ more than once). The only solution in this case I found so far was Fn-Esc (aka "Off") until the device is powered off and reboot from scratch.
Reading the post over at xda-developers, I checked the device is still reachable via network (wifi): yes, and that I can connect via ssh: true (did not tried this before, because the WLAN I use is normally fully isolated from LAN and isolates the clients also, but I took the effort...;-). So the device and debian are basically still running fine. I can't see anything special from the logs (syslog, daemon.log, repowerd.log, debug, auth.log).
Anyone any idea how to go further?
(*) Esc, typing pwd, Enter, Ctrl+Esc, three times cursor up, one time right, four times down and two times Enter ;-)
Edit:
After having ssh available I found out that
sudo service sddm restart
works around the issue by going to the initial login screen. But unfortunately that's not an option on the go...
