Hello,

I'm new to the Debian world, but with 40 years of UNIX/kernel
experience.

I own since 2023 a tablet L11, produced by Purism, see https://puri.sm/
The tablet runs a modified Debian OS, with the name PureOS.

Accidentally I cracked its display in 2023. We (my 16 years old son and I) were
able to take the tablet apart, which is not an easy thing because it is
not designed for this (the LCD is glued in). My other, son who lives and
works in China/Taiwan, was able to get the LCD from its manufacturer there
and yesterday we connected it to the PCBA and assembled enough to make
the L11 booting again. It boots, the LCD shows the messages and the Gnome
desktop, but needs an external keyboard and mouse because the
touch-layer of the LCD does not give any key input.

I could imagine that nothing were working, but because of the working
display I think more in an issue in the driver, or some whitelisting
missing of the now mounted model of the LCD.

I'm willing to dig into this, starting with the source of the driver. I
can nicely SSH into the tablet and debug what is necessary.

Short question: from where and how could I git clone the kernel sources.

Thanks in advance	

	matthias
