RE: How to recover from blank screen on sparc64
Hello Adrian!
Thanks for your prompt response.
OK - I had a bit of a problem getting the serial console to work again but I
played around a bit with the handshaking and was successful.
I thought perhaps the system was trying to start a desktop but that's not
the case. It's probably the same situation that occurred when I tried to do
the install from the cdrom: it appeared to boot from the cdrom but then the
screen went black. That's what's happening now. The problem during install
seemed to be resolved but after installing packages for a desktop the
problem is back.
I used the serial console and aptitude to install some hardware discovery
utilities. Running hwinfo --gfxcard shows the graphics card to be "Sun
Microsystems Sun|Turbo GX Plus (cgsix)". Config status is "cfg=new,
avail=yes, need=no, active=unknown"

This is normal to Debian and not related to sparc64 at all. If your system
is up-to-date, APT will have set up a systemd timer job to update your
package lists automatically once per day.

Did you try hooking up the machine to the serial console again and check the
output there?
What kind of framebuffer device do you have?
