Re: LG GRAM 14 (14Z90Q-G.AA58F) problems

Hi,

Ok some updates while I'm still experimenting with the laptop.

Ok absolutely no link with acpitz, sorry for that !

I discovered that if I touch the keyboard during the boot time (for example
to disable acpitz... or if I just press any key) then the keyboard will
work perfectly afterwards.

However, if I don't press any key during boot time then the keyboard won't work
at the login prompt. If I then log on to the machine with another pc and run
xenodm then the keyboard becomes fully functional.

I tried to change a lot of settings in the bios (lots of variables available!)
but no better on this side.

Ok I think it is a problem with cwm. I tested with fvwm and no problem at all.

So in cwm :
With xterm no problem, I can switch it to full screen (CTRL-ALT-f) and no crash.
With Chrome and mpv (the two I tested) I can maximize the windows (CTRL-ALT-m)
without problem but as soon as I switch them to full screen (CTRL-ALT-f) the
laptop freezes (with no possibility to ssh from another machine).
