Hi there.
After a very painful bug-hunting that involved switching back and
forth between distributions (Debian and Ubuntu) and many versions of
them, I finally found that the culprit for my notebook's dpms not
being able to blank my monitor screen under X was commit
e17f9c3cd589ee50ba74976d11a5804ca2562472.
Indeed, the notebook that I have *is* an MSI one (and this thing is
quite buggy) and reverting only that makes everything work again.
This was hunted, bisected, tested, and retested.
Just for the record, the symptoms when I have that commit in are that
my notebook monitor flickers *a* *lot*, like if it were trying to go
to sleep and then a keyboard event preventing it from actually
sleeping. And it doesn't sleep. OTOH, when I leave it off, everything
works fine, with the exception of the kernel generating messages
telling me that some keycodes are not known (as would be expected). I
am attaching a dmesg snippet showing the kernel complaining about the
keycodes.
Perhaps a good fix would be something related to
/lib/udev/keymaps/micro-star, but I fear that we may have to
workaround things here due to a buggy hardware.
Regards, RogÃrio Brito.
