Black screen with Weblish using upstream kernel (Glish works)
So, the title sums it up. I booted up using a upstream kernel image (5.2 Debian10), and everything is working fine, Glish works but not Weblish. Weblish just blinks some prompt information that fade too quickly giving me a black screen where keyboard doesn't work. After digging a bit I got this info:
Linode Lish Console [*] Wed Aug 28 11:14:59 EDT 2019 [*] Linode Shell (lish) Console starting... [*] [screen is terminating]
I think this [screen is terminating] is a default message of GNU screen, that is terminating before the prompt spawns for some reason… Any clues?
If you're using a customized upstream kernel, you may need to make the configuration changes detailed here for Lish access. Namely, update these settings in your /etc/default/grub file:
GRUB_TIMEOUT=10 GRUB_CMDLINE_LINUX="console=ttyS0,19200n8" GRUB_TERMINAL=serial GRUB_DISABLE_LINUX_UUID=true GRUB_SERIAL_COMMAND="serial --speed=19200 --unit=0 --word=8 --parity=no --stop=1"
Then, apply these changes:
You may need to reboot your Linode as well.
Otherwise, you may find our documentation on Lish helpful as well: Using the Linode Shell (Lish)
Hope this helps!
