Output of journalctl -b

I have an ASUS Q550LF running Arch Linux and KDM. I followed https://wiki.archlinux.org/index.php/NVIDIA_Optimus but glxgears says I have do not have any GLX support in X. I was asked on #archlinux on irc.freenode.net for the output of journalctl -b and /var/log/Xorg.0.log

A knowledgeable person determined from this line

Jul 27 11:40:45 Kilimanjaro kernel: ACPI Error: Field [TMPB] at 274432 exceeds Buffer [ROM1] size 262144 (bits) (20140214/dsopcode-236)

that there was a bug in ACPI and how that relates to detecting the video card. I am not an expert, but I was also told by this person that this bug report https://bugzilla.kernel.org/show_bug.cgi?id=60829 (Wrong ACPI handle is detected for Acer V5-573G) is similar.

Because of that, I've also attached the output of acpidump and dmesg. In addition, I've added the output of lspci. Is there anything else that you all might need to investigate this?

The error message from _ROM and _DSM all seems originated from the nouveau driver, I would suggest having the nouveau driver developer take a look first.

Comment 8 Ilia Mirkin 2014-08-04 04:03:29 UTC

There are no nouveau messages and there are NVRM messages. Do these issues happen with nouveau instead of the blob?

As for not having GLX, you're probably mixing and matching xorg/mesa and nvidia blob libraries.

The Xorg log all seems fine... you never actually stated anything about the problem you're having (beyond some annoying lines in dmesg which are usually a result of buggy ASL logic). And lastly using the blob basically gets you 0 support from most of the open source community. [FTR, the suggested config on that archlinux wiki page is pretty crazy... but it does seem like it could work.]

So... what's the issue? Is it that the proprietary nvidia drivers don't work in some way that you expect them to? Then file a bug with nvidia. If the issue, whatever it is, is reproducible without the blob drivers, feel free to update.
