So I updated debian on my N900, because having different version on phone and PC sucks.
It booted, after I added "rw" to kernel command line, which is small miracle.
But X are without usable mouse, without panel, and without reasonable keymap. In particular, I don't have numbers, or any symbols besides ',.<>'. But I have root shell. Now I need to enable remote access somehow... which will be fun because sshd disappeared.
emacs to the rescue. By editing existing script, I can get access to characters such as '/', and launch telnetd. Installing sshd was easy with nmtui. Good.
Now, it seems something changed in the X land, and "xinput --set-prop --type=int 8 249 0 1" no longer works, which means touchscreen is
"upside down". If you know the replacement commands, let me know...
