I tagged that bug critical as it has some bad effect to the hardware. I
am not fully sure where the problem lives in. The only informations that
I have I will put into this report.
I use luakit on my laptop, a Lenovo X61s with a intel GM965/GL960
graphic controller. I am not able to reproduce that bug with any other
browser or software or any other hardware. As X is involved, I will also
attach the full Xorg log of a broken session.
When I use luakit and _load new pages_ it often blanks the screen by
switching the backlight of. There is no way to switch it back on again
but with a trick, putting the laptop to sleep and waking it up again, I
get some backlight back. Some means in this case that only the right
side is lighted. I have to do a full system restart to get the proper
backlight back. I do not know if that is good for the hardware or not
but I do not think that it should be the case that a browser is able to
destroy hardware.
I have no idea what does trigger the bug but I fear about using luakit
on that laptop anymore.
